Cyclomatic Complexity

The cyclomatic complexity number is basically the number of decisions in the source code. The higher the number the more complex and the more tests you need to verify the function. E.g. a cyclomatic complexity of 3 would require at least 3 tests to verify the function.

The linter shall help you to keep your functions slim and less complex and easy to test.
