Coverage

Code coverage in PyCharm allows you to perform on-the-fly line coverage measuring for your code with low runtime overhead. In general, line coverage answers the question, "Was this line of code executed during unit testing simulation?"

Use this page to configure how coverage data is collected and processed.
