React Testing - Code and Test 3 React Web Apps

build a birthday reminder app with React from scratch, discuss a wonderful testing strategy, and implement a single test that provides a ton of coverage for the web app.

Set up a birthday reminder React app from the setup folder, run and inspect the final app, implement the user list, and learn the testing strategy for React web apps.

Build a React UI with a main wrapper and container, show birthdays in an h3, import a list component, and add a button that logs to the console on click.

Build a dynamic list component that maps over a people array, destructures name, age, image, and id, and renders each as an article with an image and name.

Implement onClick by passing an empty array to setPeople to clear the list, update the counter, and show your birthdays today. Then test the button interaction to complete the app.

Explore a testing strategy for a React web app, using the testing pyramid, prioritizing end-to-end tests, validating DOM, database, and visual look-and-feel with two validation points in one test.

Install WebdriverIO to run a visual end-to-end test with screener, render the full app, and validate load and clear-list states for 100% coverage using mocha and Source Labs.

Set up the project with webdriver io, run a WDIO test via npm run wdio, and verify the environment by watching the login test and its video output.

Configure webdriver.io with screener for visual end-to-end testing, establishing a secure service, API keys, and project naming; capture snapshots of default and cleared states to validate visuals and baselines.

Wrap up the React testing module by thanking learners for joining the tutorial and promising to see you next time.

Explore white box and black box testing of a responsive DAB portfolio web app. Use Cypress for functional tests and Gest for unit testing in React testing practice.

Create a beautiful responsive, mobile-first personal portfolio site that showcases testing and development projects, technologies, timeline, and accomplishments with a live demo and easy contact.

Pull starter code from the repository, star the project, and download dev portfolio branch to access a barebones React portfolio with components, then run npm install and npm run dev.

Build a header component with styled components and a home link, plus a social details component with social icons. Implement responsive navigation and icon-driven links for a React web app.

Implement a mobile-first testing strategy for a responsive web app. Automated visual tests verify header layout, logo overlap, icon urls, navigation, and portfolio redirects to home across devices.

Learn to build visual end-to-end tests using Happo for cross-resolution snapshots and Cypress for functional tests. Configure baselines, run visual specs, and review cross-browser reports.

Learn to validate social links in a React app with end-to-end Cypress tests, using component tests and snapshot checks to verify URLs mapped via data test id attributes.

Build and test the hero section of a React web app by adding a title, text, and a button linking to an upcoming about section, with visual and Cypress tests.

Implement the project section with a responsive card view driven by projects.map, showing title, description, image, tags, source code, and visit links, while running visual and Cypress tests.

Learn to use jest snapshot tests to validate component data and project links, complementing visual tests and ensuring risk-free UI changes in React apps.
