Why are Jasmine and Karma used for unit testing in angular?
Developers get to use a powerful unit testing tool called TestBed. Angular provides and initializes it in this file. In the end, Karma loads all the test files for the application by checking them against their names and a regular expression. All the files inside the app folder having “spec.ts” on their names are suitable for tests.
Which is the best JS library for unit testing?

This allows you to control what external methods return and to check how many times the methods are called. The method calculate calls an outside method, isAddition, which will return true or false.

What can Jasmine be used for in JavaScript?
Jasmine is a very popular JavaScript behavior-driven development (In BDD, you write tests before writing actual code) framework for unit testing JavaScript applications. It provides utilities that can be used to run automated tests for both synchronous and asynchronous code. Jasmine has many features such as:
