¶ Jasmine is a behavior-driven development framework for testing JavaScript code. It does not depend on any other JavaScript frameworks. It does not require a DOM. And it has a clean, obvious syntax so that you can easily write tests.
Similarly, what is the use of spyOn in Jasmine?
callFake() Test doubles like mocks, spies, and stubs are integral part of unit testing. In Jasmine, there are few such functions which can stub any function and track calls to it and all its arguments. They are known as spies.

What is Beforeeach in Jasmine?
The string is the title of the spec and the function is the spec, or test. A spec contains one or more expectations that test the state of the code. An expectation in Jasmine is an assertion that is either true or false. A spec with all true expectations is a passing spec.How do I debug Jasmine unit test?
