Testing complex software is itself a complex task. Modern software has millions of lines of code, and it is very difficult to ensure that developers are testing every possible path through all of that code. Test coverage analysis seeks to give developers a sense of how much of their code was evaluated during a set of tests. In this video, learn how developers compute test coverage analysis.
- [Instructor] Testing complex software…is itself a complex task.…Modern software has millions of lines of code,…and it is very difficult to ensure that developers…are testing every possible path through all of that code.…Test coverage analysis seeks to give developers a sense…of how much of the code was evaluated during a set of tests.…Test coverage is defined as the percentage…of a piece of software that was evaluated…during a given test set.…Now, that definitely probably…raises more questions than it answers.…
What do I mean by the percentage of a piece of software?…I'm being deliberately vague here for a moment,…because there are many different ways…to compute test coverage, and I'll get to them in a minute.…In general, you can compute test coverage…using a simple formula.…Divide the number of cases tested…by the total possible number of cases.…If there were 10,000 possible test cases…and your testing evaluated 9,000 of them,…you have 90 percent test coverage.…There are many different variables that you can…
