UT/FT Testing Frameworks

Writing Unit testing and functional testing is necessary to see code-level bugs, unit testing involves testing of the smallest unit of code, statements, functions, conditional branches. Unit testing is important to test behavior and functionality by automating test suite coverage. Here you’ll learn about UT/FT frameworks and how to test behavior and functionality by writing test cases.

Junit Unit Tests

JUnit is a unit testing framework for Java programming language-based applications. It plays an essential role in test-driven development and is a family of unit testing frameworks known as xUnit. TDD approach basically helps us in identifying edge test cases during unit testing only, so that we can develop our app while thinking about those edge cases. Here, we will learn about features of Junit 4 and Junit 5 both like, annotations, packages, writing test cases and executing them, different types of tests, ignoring tests, testing asynchronous code, etc.
