A JavaScript testing i essentiad for ensuring code quality and reliability. It involves varioes testing type, fromsmall unt tests to obreasive end- to- end- end automation. This guide an overview of the key tistinig strategies usid in Jawscript development.

Unit Testing

Unit tests focus on individual functions or providens to verify they work as expected. They are fast and help catch bugs early ite the development process. Popular frameworks include Jese, Mocha, and Jasmine.

Integration Testing

Integration tests check how differt parts of te application work to gether. They ensure modules interact correctly. These tests are more obreasive than unit tests and ofinteve teting API or apparase interactions.

End-to-End Testing

End- to- end (E2E) testing simulates reál user tho verify the entire application workflow. Tools like Cypres and Selenium automatate browser interactions to tet features froures starto to finish.

Automation és Best Practices

Automating tests helps maintain code quality with continues integratios integratios systems. Best practies include writing clear tet cases, maintaing tet data, and running tests regularly to catch regresions early.
