海外TECH	DEV Community	Google Charts Dashboard: a Tutorial with an Artistic Touch of MoMA 🖼	https://dev.to/cubejs/google-charts-dashboard-a-tutorial-with-an-artistic-touch-of-moma-1jdn	Google Charts Dashboard a Tutorial with an Artistic Touch of MoMA In this tutorial we ll learn how to visualize data with Google Charts a free charting service and JavaScript library by Google We ll also use Cube an open source API for building data apps to provide access to the public dataset with The Museum of Modern Art collection data In the end we ll have a dashboard with charts that tell all about MoMA s contemporary artworks Here s how the end result will look like Want to try it Here s the live demo you can use right away  Also the full source code is available on GitHub Now we re all set Please check your ticket and proceed to Floor Charting Gallery What is Google Charts Google Charts is a charting service by Google that provides a rich selection of data visualization types renders charts using HTML and SVG provides cross browser compatibility and cross platform portability meaning that charts look nice both on desktop and mobile Why is it a charting service not a charting library Indeed Google Charts provide a JavaScript library that takes the data and renders charts on the web page However unlike other data visualization tools Google Charts don t render all the charts on the client side Instead for some of the charts they pass the data to Google servers render a chart there and then display the result on the page Such an approach has its pros Rendering code is browser and platform independent which provides increased compatibility and portability If it renders once it will render anytime The size of the JavaScript library is fixed and doesn t depend on the features used And it s actually really tiny ーless than KB gzipped But it also has its cons For some charts data has to be uploaded to Google servers for the chart to be rendered If you deal with sensitive data please check the Google APIs Terms of Service Also make sure to always check the Data Policy sections in the docs In this tutorial we ll be using a public dataset so it s not a big deal Which charts are available Among the usual suspects like line charts bar charts or pie charts you can find a few distinctive ones Calendar charts that you must have seen numerous times at GitHub profiles Gantt charts that you might have wished to never encounter because of their affinity to enterprise software Diff charts that combine a couple of scatter charts pie charts or bar charts into an image that visualizes the difference between two similar datasets Vega charts that provide a way to render charts defined with Vega and Vega Lite visual grammars in Google Charts Enjoying the sight so far Please proceed to Floor Modern Arts What is MoMA The Museum of Modern Art is an art museum in New York USA It was established years ago on November and it s often identified as one of the largest and most influential museums of modern art in the world MoMA s collection includes almost works of architecture and design  drawing  painting  sculpture  photography  prints  illustrated books  film and electronic media On GitHub MoMA publishes and periodically updates a public dataset which contains records representing all of the works that have been accessioned into MoMA s collection and cataloged in our database It includes basic metadata for each work e g title artist date made medium dimensions and date of acquisition This dataset is placed in the public domain using a CC License so we re free to use it in this tutorial and available in CSV and JSON formats I ve imported this dataset to a publicly available Postgres instance that we ll use in a few minutes to explore the data Proceed to Floor Cubism What is Cube We re building a dashboard so it would be very convenient to access the data from the front end via an API Cube comes particularly handy for this purpose Cube is a popular open source product with more than stars on GitHub to date It serves as an API for building data apps You can configure Cube to connect to any database describe your data with a declarative data schema and instantly get an API that you can use in your app Let s spin up an API for the MoMA dataset First please make sure you have Docker installed on your machine It s recommended to run Cube with Docker or use a managed instance in Cube Cloud Second let s create a new folder for your Cube app and navigate to it mkdir google charts momacd google charts momaThird run this snippet to create a new docker compose yml file with the configuration We ll also use environment variables from the  env file to instruct Cube how to connect to Postgres cat gt docker compose yml lt lt EOLversion services cube image cubejs cube latest ports env file env volumes cube confEOLThen run this snippet to create the  env file with Postgres credentials In this tutorial we re using a publicly available Postgres database that I ve already set up Check the docs to learn more about connecting Cube to Postgres or any other database cat gt env lt lt EOLCUBEJS DB TYPE postgresCUBEJS DB HOST demo db examples cube devCUBEJS DB NAME momaCUBEJS DB USER cubeCUBEJS DB PASS CUBEJS API SECRET SECRETCUBEJS DEV MODE trueEOLThat is all we need to let Cube connect to Postgres The last part of configuration is the data schema which declaratively describes the contents of the database Let s put it under the schema folder mkdir schematouch Artworks jsPlease copy and paste this data schema into Artworks js then follow the comments in the file cube Artworks Cube definition It says that the data is kept in the artworks table Learn more in the docs sql SELECT FROM public artworks Quantitative information about the data e g count of rows It makes sense for all rows rather than individual rows measures count type count minAgeAtAcquisition type number sql MIN CUBE ageAtAcquisition avgAgeAtAcquisition type number sql SUM CUBE ageAtAcquisition CUBE count maxAgeAtAcquisition type number sql MAX CUBE ageAtAcquisition Qualitative information about the data e g an

heightCm sql ROUND CUBE Height cm type number widthCm sql ROUND CUBE Width cm type number dataSource default Whew Now we re finally ready to run Cube docker compose upNow let s review the data in the MoMA dataset Cube provides the Developer Playground a convenient web based tool that helps explore the data at localhost Navigate to the Developer Playground in your browser and explore the UI You can retrieve arbitrary data slice and dice the dataset by selecting dimensions and measures For example you can check how many artworks MoMA has for the artists that have Sarah in their name To do so select the Artworks count measure the Artworks artist dimension and also make sure to add a filter for the Artworks artist dimension that allows only the names containing Sarah Feel free to tinker with other measures and dimensions Once you re done let s get to building the dashboard Proceed to Floor Abstract Art Building a dashboard with Google ChartsNow it s time to develop a front end application telling the story behind the MoMA artworks collection with charts and other types of data visualizations For simplicity let s build it with pure JavaScript and without any frameworks however unofficial packages are available on NPM for React Angular and Vue as well as TypeScript definitions in the DefinitelyTyped repository Basic dashboard First let s create a subfolder for the dashboard under the google charts moma folder mkdir dashboard appcd dashboard appSecond let s start with an HTML file with the following contents You can name it basic html and put in that dashboard app folder We ll go through this file line by line Follow the comments lt html gt lt head gt lt Load Cube API library UMD version for in browser use gt lt script type text javascript src cubejs client

with just a couple of them function drawCharts drawChartForArtworkArtists drawChartForArtworkYears Function that creates a table chart See the docs to learn more function drawChartForArtworkArtists Cube query that will fetch ーartists names ーcount of artworks for each artist ーbut only for those artworks that are labeled as paintings Learn more about query format in the docs const query dimensions Artworks artist measures Artworks count filters member Artworks classification operator equals values Painting Let s execute the query via the Cube API cubeApi load query then resultSet gt and process the result set First let s turn it into an array of two element arrays with names and counts const rows resultSet tablePivot map function row return row Artworks artist parseInt row Artworks count Second let s convert it into Google Charts data table Note that we re passing an array of column names as the first row const data google visualization arrayToDataTable Artist Paintings rows Third let s specify a few options like pagination const options showRowNumber true page enable pageSize width Eventually let s render the chart It will be inserted in place of an HTML element with a known id const chart new google visualization Table document getElementById chart artists chart draw data options Function that creates a scatter chart See the docs to learn more function drawChartForArtworkYears Cube query that will fetch ーproduction years ーacquisition years ーcount of artworks for each year created year acquired pair ーbut only for those artworks that are labeled as

unlikely that MoMA can acquire an artwork before it was created right Less than lines of code allowed us to include all libraries query an API transform the data configure charts and render them side by side on the page Not that bad However I wouldn t call it a full fledged dashboard until it allows interaction with elements and change how the data is represented Let s explore how to work with events and cross link the charts Interactive dashboard Please create another file you can call it index html It will contain more lines of code so we ll have more charts and some bits of code that allow working with events Copy and paste the code from GitHub ーand let s go through the most interesting parts together Now we have many charts and many functions to draw them function drawCharts artistFilters drawChartForArtworkArtists artistFilters drawChartForArtworkMediums artistFilters drawChartForArtworkYears artistFilters drawChartForArtworkWidthsHeights artistFilters drawChartForArtworkAcquisitions artistFilters drawChartForArtworkAcquisitionsIn artistFilters drawChartForArtworkAcquisitionsAge artistFilters One of the charts the table with artists names has got an event listener that is fired every time you select one or many table rows or clear the selection As you can see we somehow build the filter for the data using the buildQueryFilter function and then pass this filter to every other chart google visualization events addListener chart select function const artistsFilter buildQueryFilter resultSet chart Artworks artist drawChartForArtworkMediums artistsFilter drawChartForArtworkYears artistsFilter drawChartForArtworkWidthsHeights artistsFilter drawChartForArtworkAcquisitions artistsFilter drawChartForArtworkAcquisitionsIn artistsFilter drawChartForArtworkAcquisitionsAge artistsFilter Here s how we build the filter We access selected rows via chart getSelection If there are no rows selected the filter will be undefined If there are any we ll find the values of selected cells and use them as values in the Cube query filter function buildQueryFilter resultSet chart member const selectedRowNumbers chart getSelection map function x return x row if selectedRowNumbers length return const values resultSet tablePivot filter function row i return selectedRowNumbers indexOf i map function row return row member return member operator equals values That s all you need to add interactivity to the dashboard See how the charts change upon the selection of one or many artists in the first table It s a kind of art isn t it ‍Actually these charts and this whole tutorial are inspired by the work of others that I d like to mention here A Nerd s Guide To The Paintings At MoMA by FiveThirtyEight MoMA on GitHub by YYYY MM DD and this tweet by Steven Lubar Cleaning Off the PaintThank you for reading and following this tutorial I encourage you to spend some time in the docs and explore what else Google Charts are capable of You ll find even more chart types configuration options and advanced features Also thanks for learning about Cube and building dashboards I hope you enjoyed it Please don t hesitate to like and bookmark this post write a comment and give a star to Cube on GitHub I hope that you ll try Cube and Google Charts in your next production gig or your next pet project Good luck and have fun Now proceed to the

海外TECH	DEV Community	Thinking outside the box: An online resume with Docz	https://dev.to/linksake/thinking-outside-the-box-an-online-resume-with-docz-1ila	Thinking outside the box An online resume with DoczOne of the best traits of humankind is its curiosity It is so human that in honor of it we named a Mars rover Curiosity in Talking about curiosity in the developer world open source projects top the list since by nature they invite us to experiment modify and share what else we can do with them This is why I propose to think a little outside the box with Docz a software documentation tool that is completely open source IndexWhat is Docz Creating our Docz projectAdding our informationAdding a custom componentDeploy to GitHub PagesParting note What is Docz Docz is a Gatsby based project that simplifies the process of documenting other projects without worrying about configuration speed and support It provides a library that allows you to write MDX pages instead of HTML or JSX files handles the routing and provides plugins for all the other needs that you may have All of this results on projects anyone can contribute to Is this simplicity and friendliness that makes Docz a great option for more than just docs Creating our Docz project Before we can jump into Docz there are some prerequisites that you will need have in order to create the project NodeJSYarn or npmNow that you have the prerequisites let s start by creating a new React app with create react app CRA Go to your terminal and run npx create react app my resumeIf you don t have CRA installed npm will ask you if it s okay to install create react app type y to continue and let CRA create the new project We are using the command npx instead of npm since we want to execute a package not install it to a project You can read more about it here Now lets move to the directory of our project and install Docz cd my resumeyarn add docz or npm install doczThen let s remove everything that CRA created for us inside the src folder since we don t need it rm src Also it is a good idea to add to the gitignore the docz folder since we only needed for development gitignore Docz generated files docz Let s go and create a file named index mdx and a hello world header in the following way lt src index mdx gt name Hello Worldroute Hello world from Docz And it s time to run our development server to see what we have just created yarn docz dev or npm run docz devIf you get an error ERROR while trying to run the development server just delete your yarn lock or package json lock and the node modules folder and install the dependencies again Et voila We have successfully created our Docz project Now is a good time to commit your files Your time to shine Before we start adding more pages let s create a configuration file named doczrc js on the root of our project This will help us to set some meta tags easily but it manages all the configuration of our project doczrc jsexport default title Luis Angel Ortega description Hello I m Luis Angel and this is my resume made with Docz ignore README md The title key will set the suffix for our title tag and it will change the text on the top left corner of our project since it s an online resume I recommend using your name in this field Then the description key that we added will modify the meta description tag on our webpage to display it when it s looked up or shared online The last key will tell Docz to ignore some files and don t display them on the webpage as is in this case with the README file Now let s add more pages I ll add a contact page with my socials and resume one in the following way lt src contact mdx gt name Contactroute contact Contact me Let s talk You can find me on these platforms ️ Email mailto hey luisangelme

the Blockchain Mobility Hackathon in Barcelona Spain As you can see using MDX means that we can use Markdown syntax and JSX in the same document giving a lot of flexibility and customization to our Docz projects At the end they will look something like this Spice it Adding a custom component Now let s focus on our index mdx file Let s change it s title to About me lt src index mdx gt name About meroute Hello world from Docz And then create a components folder inside of the src directory There create a welcome jsx component this will replace our Markdown heading to make the root page more interesting src components welcome jsximport React from react const Welcome props gt const style container display flex flexDirection column textContainer textAlign center imgContainer paddingTop em

displays it all centered and the image as a circle but you can make your creativity go wild on this one Next let s change index mdx to import our component and use it to give a warm welcome to all the visitors on our webpage here is how it looks It s alive Time to deploy ow that we have our Docz project it s time to build it and deploy it to GitHub Pages since we already have the repository there First we need to configure some things go to your doczrc js file and add a dest key with the value “ docs and a base key the name of your repo as it s value doczrc jsexport default title Luis Angel Ortega description Hello I m Luis Angel and this is my resume made with Docz ignore README md dest docs base docz resume The first key is telling Docz to build the project into the docs directory we re doing this since GitHub Pages expects the static files to be on the root or docs directories The base key is changing the base folder to match the name of the repo in order to make the public files and links to work in GitHub Pages Once we have everything correctly configured we need to build the project with the following command yarn docz build or npm run docz buildWhen it is done you will see a docs folder on your project Commit and push everything to your repo After that let s go to the settings tab on your project and in the left menu go to the Pages section Then select your main branch or the branch on which you are working on and select the docs folder And that is it In a few minutes your website should be live on the link that GitHub has given you The future awaits In this article we only scratched the surface of what Docz is capable of so be sure to check their documentation to learn more I encourage you to read about them to make your resume stand out from the crowd and always remember to support the creators of this amazing project and contribute if you can Find the repo of the project here For end result check out GitHub	2021-10-21 16:45:34
海外TECH	DEV Community	Android — Instrumentation test with hilt	https://dev.to/mahendranv/android-instrumentation-test-with-hilt-2ep6	Android ーInstrumentation test with hiltTesting in Android has been a pain from the beginning and there is no standard architecture setup to execute the frictionless test As you know there is no silver bullet for all the snags This piece of article covers how do you fake dependencies to your hilt viewmodel and assert the same from fragment using espresso What do we achieve here Decoupled UI from navigation and real data sourceFeed fake data to our viewmodelA less flaky test since we control the data or Explained in a single pictureThanks Mr Bean Art disaster Contents Testing strategy Dependency overview Test runner setup Shared test fakes Writing integration test Instrumentation or UI tests Faking modules The HiltAndroidTest Wrapup Resources Testing strategy code coverage is a myth and the more you squeeze towards it you end up with flaky tests Provided the content is dynamic and involves latency due to API calls it is simply hard to achieve So to what degree we should write tests credits mediumUnit tests Small amp fast Even with a large number of tests there won t be much impact on execution time Integration tests Covers how a system integrates with others ex How viewmodel works with the data source Cover the touchpoints Runs on JVM reliable UI tests Tests that cover UI interactions In android this means launching an emulator and running tests in it Slow dead slow So write tests to assert fixed UI states Wrapup at the end of the article should give a rough idea of execution time Here we cover how to write the integration and UI tests using hilt Before the actual implementation take a minute to read on test doubles literally a very short article We ll be using Fakes in our tests Keep in mind while coding Hilt resolves a dependency by its type So our code should refer to the Fake able dependency as interface Provide your dependency in module So that the whole module can be faked along with dependencies More on this is covered in faking modules section Dependency overviewTo recap from previous article we have a fragment that requires a Profile POJO object which is provided through a ViewModel DataRepository acts as a source of truth here and returns a profile ProfileViewModel is unaware of the implementation of DataRepository and Hilt resolves it at compile time Adding to the existing implementation we ll bring in our Fake data source FakeDataRepoImpl for tests So the rest of the post is about instructing Hilt to use FakeDataRepoImpl instead of DataRepositoryImpl Test runner setupAdd test dependencies to app level gradle file This brings a HiltTestApplication and annotation processor to the project now As we ve seen in the scope section HiltTestApplication will hold singleton component File app build gradledependencies Hilt testing androidTestImplementation com google dagger hilt android testing kaptAndroidTest com google dagger hilt android compiler Although HiltTestApplication is present in our app it is not used in tests yet This hookup is done by defining a CustomTestRunner It points to the test application when instantiating the application class for instrument tests File app src androidTest java com ex hiltespresso CustomTestRunner ktimport androidx test runner AndroidJUnitRunnerimport dagger hilt android testing HiltTestApplicationclass CustomTestRunner AndroidJUnitRunner override fun newApplication cl ClassLoader className String context Context Application return super newApplication cl HiltTestApplication class java name context And the final step is to declare the test runner in app gradle file File app build gradleandroid defaultConfig testInstrumentationRunner androidx test runner AndroidJUnitRunner testInstrumentationRunner com ex hiltespresso CustomTestRunner Shared test fakesIn android there are Unit and Instrumentation tests Although both identify as tests they cannot share resources between them Here few places where tests will lookup for classes main source set here we place the production code Fakes have no place heretestShared source set This is the recommended way to share resources Create the below directory structure and place the FakeDataRepoImpl there File app src testShared java com ex hiltespresso data FakeDataRepoImpl ktclass FakeDataRepoImpl Inject constructor DataRepository override fun getProfile Profile name Fake Name age The next step is to add this to test and androidTest source sets In app level gradle file include testShared source set to test sources File app build gradleandroid sourceSets test java srcDirs projectDir src testShared androidTest java srcDirs projectDir src testShared Writing integration testIn the integration test we ll verify data source and viewmodel coupling is proper As seen in the testing strategy section tests run faster if the emulator is not involved Here ViewModel can be tested without UI All it needs is the DataRepository In the last section we placed the FakeDataRepoImpl in the shared source set Let s manually inject it and assert the data File app src test java com ex hiltespresso ui profile ProfileViewModelTest kt RunWith JUnit class class ProfileViewModelTest lateinit var SUT ProfileViewModel Before fun init SUT ProfileViewModel FakeDataRepoImpl Test fun Profile fetched from repository assertThat Name consumed from data source SUT getProfile name is Fake Name Why ProfileViewModel is instantiated manually instead of using Hilt This is the piece of HiltViewModelFactory which instantiates ProfileViewModel The SavedStateRegistryOwner defaultArgs are coming from Activity Fragment that is marked with AndroidEntryPoint So instantiating the viewmodel with hilt also brings in the complexity of launching the activity and testing the viewmodel from there This will result in a slower test whereas viewmodel test can run on JVM like we did above public HiltViewModelFactory NonNull SavedStateRegistryOwner owner Nullable Bundle defaultArgs NonNull Set lt String gt hiltViewModelKeys NonNull ViewModelProvider Factory delegateFactory NonNull ViewModelComponentBuilder viewModelComponentBuilder Instrumentation or UI testsInstrumentation UI tests run on emulator For this project we ll assert whether the name in UI matches the one in fake data source In a real world application the data source is dynamic and mostly involves a web service This means UI tests tend to get flaky So the ideal approach is to bring down the UI to have finite states and map it to the ViewModel and fake it Example UI states UI when the network response has failedUI when there are N items in the list vs the empty state Kotlin sealed classes are a good fit to design an FSM The aforementioned use cases are not covered here and won t fall into a straight line to write an article So here is the blueprint on how do we inject our fake for ViewModel … Faking modulesFor instrument tests androidTest hilt is responsible for instantiating the ViewModel So we need someone who speaks Hilt s language Create a fake module that will provide our FakeDataRepoImpl to the viewmodel File app src androidTest java com ex hiltespresso di FakeProfileModule ktimport dagger hilt android components ViewModelComponentimport dagger hilt testing TestInstallIn Hey Hilt Forget about the ProfileModule use me instead TestInstallIn components ViewModelComponent class replaces ProfileModule class Moduleclass FakeProfileModule Provides fun getProfileSource DataRepository FakeDataRepoImpl Notice the TestInstallIn annotation Defining the replaces array will make the original ProfileModule replaced with FakeProfileModule While building the component hilt will replace the original module and thus dependencies and instantiate the ViewModel with the fake repo Our UI will use the viewmodel and tests will assert the same … The HiltAndroidTestThe final piece is to write a test that uses the faked component All it needs is a couple of test rules and annotation from Hilt Rest is generated File app src androidTest java com ex
