海外TECH	DEV Community	What is a unit test?	https://dev.to/scc33/what-is-a-unit-test-3n9j	What is a unit test Unit Testing BackgroundTl dr a unit test is code that tests other code Unit tests are the smallest type of software testing They are meant to verify that a single piece of code is working as intended Unit testing is typically automated and developers run tests as part of the development process to make sure everything is working appropriately Unit tests are commonly run on every build or change to the codebase Unit testing can fall into the category of TDD or test driven development TDD is a common method in extreme programming and agile where unit tests are written before the code Unit tests can sometimes be difficult to write because code often relies on outside components In these cases stubbing or mocking are common techniques to implement unit tests Unit Testing FrameworksThere are hundreds of testing frameworks in existence because unit testing is so common Wikipedia maintains a long list of testing frameworks for many languages Some of the most popular frameworks are Junit for Java Mocha for JavaScript and PyTest for Python AdvantagesUnit tests are small and typically quick to run The speed makes them easier to check and hastens development Unit testing can be helpful documentation because it shows how the code is properly used and can give insight into functionality Developers can use unit tests as a helpful sanity check to make sure their code is working as intended and under many scenarios DisadvantagesSince unit tests are checking only small chunks of code they cannot catch large errors that exist on the system level Other testing methods like integration tests are required for verifying the system behavior Writing and maintaining unit tests can often be difficult because developers are focused on writing deliverable code for customers Unit tests like all testing may not cover every edge case or may be incorrect Therefore relying too heavily on unit tests creates a false sense of security that the code is working as intended Further ReadingUnit tests are just the first level of testing More types of testing can be read about in my series on software testing and its methods	2022-03-29 02:41:08

海外TECH	DEV Community	Eloquent optimization: displaying only one record of a one-to-many relationship	https://dev.to/cosmeoes/eloquent-optimization-displaying-only-one-record-of-a-one-to-many-relationship-2o4o	Eloquent optimization displaying only one record of a one to many relationshipSometimes we need to display data for only one record in our one to many relationships For example Displaying the title of the last video each user postedShowing the most sold product in each categoryShowing the last comment on every blog postetc In this article I want to go over the different ways we can do this and figure out the most efficient way in both terms of time and memory The naive approachIn this article I m going to use the example of a platform where users can publish videos and I want to show the title of the last video for each user One way to do this is retrieving the users in the controller and then in our blade template order the videos by the created at date grab the first and then show the title return view users users gt User get foreach user as users lt Table html gt lt td gt user gt lt td gt lt td gt user gt videos gt sortByDesc created at gt first gt title lt td gt endforeachIn this database I seeded users with videos each to figure out the performance of the queries Using Laravel debugbar I can see that we are making queries to the database and loading models into memory This is very inefficient for what we are doing Let s fix this query Solving the n issueIf you are not familiar with n issues what I m referring to is that we are making one query per user meaning that if we are showing users we would make queries if we are showing users we will make queries This is the issue we are currently facing with our application One way that Laravel offers to fix this is by using eager loading And we can do this by adding a with videos call to our eloquent query return view users users gt User with videos gt get This simple change solves our n issues If I look at the Laravel debugbar output now I see that the queries we reduced to only This is a big improvement but we are still loading models into memory meaning that we are retrieving all the videos for every user from the database Let s fix that Retrieving only the last videoFortunately Laravel offers a simple way to create a relationship for the latest video the relationship will look something like this in our User model public function latestVideo return this gt hasOne Video class gt latestOfMany This way we can retrieve only the last video from a user using user gt latestVideo and since it s a relationship we can eager load it as well So let s make use of our new relationship in our controller return view welcome users gt User with latestVideo gt get And In our blade template foreach user as users lt Table html gt lt td gt user gt lt td gt lt td gt user gt latestVideo gt title lt td gt endforeachNow If I check Laravel debugbar we are only making queries since we are using eager loading and we are loading models into memory users and videos But I still think we can make it a little better what if we didn t have to load any video model and instead only fetched the title Fetching only the last video titleTo fetch only the title of the latest video we can use the addSelect method Using this method we can add a subselect that will be added as a column to our query Here is what I came up with users User addSelect latest video title gt Video query gt select title gt whereColumn user id users id gt orderByDesc created at gt limit gt get return view users users gt users In this query we select the title we add a where to make sure the video belongs to the user order the results by the created at column in descending order and then limit the results to only to grab the first one This is not as easy to read as the previous method so let s create a scope in our user model instead of doing this work in the controller public function scopeWithLastestVideoTitle query query gt addSelect lastest video title gt Video query gt select title gt whereColumn user id users id gt orderByDesc created at gt limit And in our controller we can just call the scope return view welcome users gt User withLastestVideoTitle gt get Then we need to change our blade template to use this new generated column foreach user as users lt Table html gt lt td gt user gt lt td gt lt td gt user gt lastest video title lt td gt endforeachUsing Laravel debugbar for the last time I can see that we got our page from making queries and loading models to making queries and loading only models into memory Pretty neat If you liked this article follow me on Twitter I post tips and other Laravel content there	2022-03-29 02:26:23
