To answer this question, it's first important to understand what cyclomatic complexity is. In short, it's a measure of the number of independent paths through a piece of code. A high cyclomatic complexity indicates that a piece of code is complex and difficult to understand. Unit tests are an important tool for keeping cyclomatic complexity under control. By testing individual pieces of code, unit tests can help to ensure that code is doing what it's supposed to do and nothing more. This can help to keep code clean and easy to understand. In addition, unit tests can provide a safety net that catches errors before they cause problems in production. As a result, unit tests and cyclomatic complexity are closely related, and both should be given careful consideration in any software development project.
