Unit Test is an automated test that you write a few lines of code to create. A unit test checks that a specific part of the code functions as expected.

Test suite generators could help software engineers to ensure software quality by detecting software
faults. These generators can be applied to software projects that do not have an initial test suite, a
test suite can be generated which is maintained and optimized by the developers. Testing helps to
check if a program works and, also if it continues to work after changes.
