Run Infection on your code

Infection makes small changes to the source code, called mutants, and runs your test against each one.

• .Killed means a test failed with the change, so the tests noticed it.
• MEscaped means every test still passed. A test is missing for that behavior.
• UUncovered means no test executes that line.

Press Run or ⌘↵ to start.

Runs are public and listed in Explore. Don't paste code you can't share.
