v0.16.1

0.16.1 (2024-04-18)

This release updates Scalameta to 4.9.3, resolving an issue some users might have when another plugin is also using a recent version of Scalameta.

v0.16.0

0.16.0 (2023-12-27)

This release mainly features improved reporting. The biggest feature is inclusion of tests in the report. Stryker4s will now show all your test suites, and (if supported) the individual tests of each test suite. This makes it easier to see which tests cause failing mutants.

Test output

In the HTML report, a new tab is added to show the test results:

Opening a test suite reveals the tests inside that suite, clicking on one shows more information available about what mutants it covers and might have killed:

Back on the mutant tab, each mutant will now show what tests are covered by it. And for killed mutants the test exception output is shown:

Regex mutations

Regex mutations now show the precise characters inside the expression that has been mutated as its location, and a richer description with info about the mutation is added:

Stryker4s v0.15.2

🐛 Bugfixes

• Set --release javac option to 8 (#1458) @hugo-vrijswijk

Stryker4s v0.15.1

Stryker4s v0.14.2

This release updates log4j to 2.16.0 for the command-runner to fix the security issue. If you use the sbt or Maven plugin, this has no impact as those plugins do not use log4j. If you use the command-runner, upgrading is recommended.

Also updates the HTML report to a newer version with some performance fixes and a new 'diff' view #1028:

🧰 Maintenance
