Code testing tools help developers write, run and measure automated tests of their source code. Paid tools range from AI agents that generate unit and API tests, through continuous test runners inside the editor, to hosted services that track coverage and catch flaky tests in CI. Free open-source projects supply the test frameworks, coverage tools, test generators and mutation testers that most teams build on. This comparison covers ten paid tools and ten open-source projects against the same fifteen capabilities.
