Description
JEST has achieved remarkable popularity within the jаvascript ecosystem, standing out as a premier testing framework that developers turn to for various projects. Its rise in popularity can be attributed to several key factors:Like it has a User-Friendly Setup, Jest offers a straightforward and painless setup process, reducing the barrier for entry and making it accessible to developers of all levels.Jest comes bundled with essential testing tools, such as an assertion library (matchers), mocking capabilities, and a test runner. This comprehensive package saves developers time and effort by eliminating the need to piece together multiple libraries.Jest's intuitive API and descriptive syntax make it easy for developers to write expressive and readable tests. This helps teams maintain code quality and collaboratively contribute to the testing suite.By enrolling this course, you can learn all about JEST in one place , below are the topics cover in this course:.
