Jasmine is Angular’s default testing framework, providing a behavior-driven development syntax for writing clean, readable tests. As the creator of CoreUI with over 12 years of Angular experience since 2014, I’ve used Jasmine extensively for testing thousands of components and services. Jasmine offers describe blocks for test suites, it blocks for individual tests, and powerful matchers for assertions. The framework includes spies for mocking functions and tracking calls without external dependencies.
