Why Is Unit Testing of Angular Apps Important?
You may check your application for coding bugs and unusual user behavior with Angular unit tests. It can be time-consuming and ineffective to test every potential behavior, but creating tests for each coupling block in your application will help you find issues with each one.

The creation of a test for each block is among the simplest methods for determining that block's strength. Rather than waiting for a bug to show up in production, you should take this action. Unit tests can be written for blocks (components, services, etc.) to help find and repair errors early in the development cycle.
