The testing phase is one of the most essential phases of the software development life cycle process. The different types of testing discussed in this article can be executed through both manual and automated tests. But how do you know which testing is best for certain parts of the application testing? How do you know you will get full test coverage?
This article will cover:
- Unit testing
- Integration test
- System test
- Why do we need all these different types of tests?
Unit testing

They will also be able to know what should be…
