The Jasmine framework includes a function called SpyOn() that lets you spy on a particular line of code.
SpyOn() and CreateSpy are the two spying technologies that Jasmine supports ().
ToBeTruthy matches the output as true, while toBeFalsy matches the output as false.
A global function is the it() method.
We use the special matcher any when we are dubious of the output.
Check whether any variables were previously undefined with the toBeUndefined () function.
The following are some Jasmine.js substitutes:
‥ Mocha
‥ Jest

These businesses make use of Jasmine:

The afterEach() method is called following the completion of each test specification.
The Jasmine Clock, which may be used to control how much time passes throughout your tests, is managed by the Jasmine.Clock () command.
