Remember that your test programs will probably bear almost no resemblance to the actual applications you build with your code. Unit testing alone won t guarantee quality software. First, the tests have to be designed to uncover potential bugs. The tests must be run whenever you change the underlying code. Developers use coverage tools to ensure unit tests adequately test their code before checking it in.
Testers use coverage tools to ensure that system tests adequately test the code before release.
Testing and code coverage analysis work together to help ensure higher-quality software. Contact our webmaster .
