ITNEXT·4yFront-end Testing Principles
For the Front-End we need to focus on only two targets for our tests: the end-user who interacts with your component in the browser and the developer who renders and uses your component. Writing your tests in isolation will guide us to a better way to write your tests to improve their reliability, simplify the code, and increase confidence.
Community Picks·3yCI/CD Tutorial For Developers
Continuous integration (CI) and continuous delivery (CD) helps IT organizations streamline their development process by automating manual tasks related to code deployment. Continuous delivery automates the release process and ensures that code is always in a releasable state. CI/CD can also be as simple as moving away from software delivery practices to cloud-native ones.
