海外TECH	DEV Community	An Overview of UI | UX	https://dev.to/ohdylan/an-overview-of-ui-ux-7f	An Overview of UI UXWe are going to discuss a little bit about the differences between UI and UX in this article UI which stands for User Interface acts as a bridge between users and the visual content on the screens The screens could range from desktops laptops tablets to our mobile phones UI is more towards tangible and visible design For example the buttons scroll bar and even the colour palettes used by the website are also parts of UI Image from Technology vector created by freepik www freepik comUI decides the aesthetic and feel for the website Either you want your app to be more playful e g A travelling information website or to be more serious e g Scientific research UI plays an important role UI design has also evolved and improved over time as it has to be responsive to different screen sizes An example would be we are not going to show a huge side bar when the website is displayed on a phone s browser instead we could hide it with a togglable hamburger menu In this case UI designers have to draft out different wireframes and figure out how do they look the best with all the elements on the screen They will normally create sample pattern library mood boards and static interface to determine the design of an app   UX refers to User Experience design including research testing planning etc UX design cares about how users feel when accessing and navigating through the app The workflow of UX design from ideation to the creation of prototype will be covered in the future articles This is an example of simple wireframes and the navigation routes for an app UX design also involves getting users feedback in the early stages of designing phase and make improvements to the flow For example when user clicks on an icon he or she found out that some important information on the interface is blocked by the popped up modal window In this case the layout can be adjusted to optimize the overall experience of our app Follow me for more future articles on web design programming and self improvement	2021-11-05 09:44:23

海外TECH	DEV Community	Creating a React component with TDD	https://dev.to/mbarzeev/creating-a-react-component-with-tdd-2jn8	Creating a React component with TDDJoin me in this post as I create a React component using Test Driven Development TDD approach I am going to create a confirmation component which has the following features A static titleA confirmation question and this can be any question the app would like to confirmA button for confirming supporting an external handlerA button for canceling supporting an external handlerBoth buttons are not aware of what happens when they are clicked since it is out of the component s responsibilities but the component should enable other components containers which use it to give it a callback for these buttons Here how it should look So with that let s get started The process of TDD is a cycle of writing a test gt watch it fail gt write the minimum code for it to pass gt watch it succeed gt refactor if needed gt repeat and this is what I m going to practice here It may at some point appear to you as tedious or perhaps impractical but I insist on doing this by the book and leave it to you to decide whether it serves your purposes well or you d like to cut some corners on the way Off we go with the test file first I got my Jest testing env running on watch mode and created the component s directory named “Confirmation and an “index test js file residing in it The first test is pretty abstract I want to check that rendering the component renders something anything to make sure my component exists In practice I will render my still not existing component to see if I can find it on the document by its “dialog role import React from react import render from testing library react describe Confirmation component gt it should render gt const getByRole render lt Confirmation gt expect getByRole dialog toBeInTheDocument Well you guessed it Jest does not know what “Confirmation is and it is right Let s create that component just enough to satisfy this test import React from react const Confirmation gt return lt div role dialog gt lt div gt export default Confirmation I imported this Component to my test and it passed now Great Next we would like to have a title for this component For the purpose of this walkthrough the title is static and should say “Confirmation Let s create a test for it it should have a title saying Confirmation gt const getByText render lt Confirmation gt expect getByText Confirmation toBeInTheDocument The test fails now we write the code to make it pass import React from react const Confirmation gt return lt div role dialog gt lt h gt Confirmation lt h gt lt div gt export default Confirmation Moving to the next feature we want to make sure that there is a confirmation question in this component I want this question to be dynamic so it can be given from outside the component and I think that having the question as the “children of the Confirmation component is the right way to go about it so here s how the test for that looks like it should have a dynamic confirmation question gt const question Do you confirm const getByText render lt Confirmation gt question lt Confirmation gt expect getByText question toBeInTheDocument Again the test fails so I write the code to make it pass import React from react const Confirmation children gt return lt div role dialog gt lt h gt Confirmation lt h gt lt div gt children lt div gt lt div gt export default Confirmation On for the buttons I will start with the confirm button We first want to check that there is a button on the component which says “OK From now on I will write the test first and the code which satisfy it after Test it should have an OK button gt const getByRole render lt Confirmation gt expect getByRole button name OK toBeInTheDocument I m using the “name option here since I know there will be at least one more button in this component and I need to be more specific about which I d like to assertComponent import React from react const Confirmation children gt return lt div role dialog gt lt h gt Confirmation lt h gt lt div gt children lt div gt lt button role button gt OK lt button gt lt div gt export default Confirmation Let s do the same thing for the “Cancel button Test it should have an Cancel button gt const getByRole render lt Confirmation gt expect getByRole button name Cancel toBeInTheDocument Component import React from react const Confirmation children gt return lt div role dialog gt lt h gt Confirmation lt h gt lt div gt children lt div gt lt button role button gt OK lt button gt lt button role button gt Cancel lt button gt lt div gt export default Confirmation Ok nice So we got the component rendering what we want not styled but that s another story and now I would like to make sure I can pass handlers for the buttons of this component from outside and make sure that they are being called when the buttons are clicked I will start from the test for the “OK button it should be able to receive a handler for the OK button and execute it upon click gt const onConfirmationHandler jest fn const getByRole render lt Confirmation onConfirmation onConfirmationHandler gt const okButton getByRole button name OK fireEvent click okButton expect onConfirmationHandler toHaveBeenCalled What I did was to create a spy function give it to the component as the “onConfirmation handler simulate a click on the “OK button and assert that the spy has been called The test obviously fails and here is the code to make it happy import React from react const Confirmation children onConfirmation gt return lt div role dialog gt lt h gt Confirmation lt h gt lt div gt children lt div gt lt button role button onClick onConfirmation gt OK lt button gt lt button role button gt Cancel lt button gt lt div gt export default Confirmation Sweet let s do the same for the “Cancel button Test it should be able to receive a handler for the Cancel button and execute it upon click gt const onCancellationHandler jest fn const getByRole render lt Confirmation onCancellation onCancellationHandler gt const cancelButton getByRole button name Cancel fireEvent click cancelButton expect onCancellationHandler toHaveBeenCalled Component import React from react const Confirmation children onConfirmation onCancellation gt return lt div role dialog gt lt h gt Confirmation lt h gt lt div gt children lt div gt lt button role button onClick onConfirmation gt OK lt button gt lt button role button onClick onCancellation gt Cancel lt button gt lt div gt export default Confirmation And here is the full tests file import React from react import render fireEvent from testing library react import Confirmation from describe Confirmation component gt it should render gt const getByRole render lt Confirmation gt expect getByRole dialog toBeInTheDocument it should have a title saying Confirmation gt const getByText render lt Confirmation gt expect getByText Confirmation toBeInTheDocument it should have a dynamic confirmation question gt const question Do you confirm const getByText render lt Confirmation gt question lt Confirmation gt expect getByText question toBeInTheDocument it should have an OK button gt const getByRole render lt Confirmation gt expect getByRole button name OK toBeInTheDocument it should have an Cancel button gt const getByRole render lt Confirmation gt expect getByRole button name Cancel toBeInTheDocument it should be able to receive a handler for the OK button and execute it upon click gt const onConfirmationHandler jest fn const getByRole render lt Confirmation onConfirmation onConfirmationHandler gt const okButton getByRole button name OK fireEvent click okButton expect onConfirmationHandler toHaveBeenCalled it should be able to receive a handler for the Cancel button and execute it upon click gt const onCancellationHandler jest fn const getByRole render lt Confirmation onCancellation onCancellationHandler gt const cancelButton getByRole button name Cancel fireEvent click cancelButton expect onCancellationHandler toHaveBeenCalled And I think that that s it We have all the building blocks and logic of our component implemented and fully tested Yes I know the style is off but this is something we can fix after we are certain our building blocks are intact and all works according to spec Aside from walking with me in creating this component using TDD this post is clear evidence TDD can be applied and rather easily when developing UI components TDD will guide you step by step through your component features spec and help you focus on what matters while supplying a safety net for future refactoring This is really awesome As always if you have any ideas on how to make this better or any other technique be sure to share with the rest of us CheersHey If you liked what you ve just read check out mattibarzeev on Twitter Photo by Jo Szczepanska on Unsplash	2021-11-05 09:23:20
