## Mutation Testing with PIT

To run mutation tests and coverage, add the following to your build file:

```java
@BuildCommand(summary = "Run PIT mutation tests")
public void pit() throws Exception {
    new PitestOperation()
        .fromProject(this)
        .reportDir(Path.of("reports", "mutations"))
        .targetClasses(pkg + ".*")
        .targetTests(pkg + ".*")
        .verbose(true)
        .execute();
    }
```

```console
./bld compile pit

```

Please check the [PitestOperation documentation](https://rife2.github.io/bld-pitest/rife/bld/extension/PitestOperation.html#method-summary) for all available configuration options.

## Pitest (PIT) Dependency

Don't forget to add the Pitest `test` dependencies to your build file, as they are not provided by the extension. For example:

```java
repositories = List.of(MAVEN_CENTRAL);
scope(test)
    .include(dependency("org.pitest", "pitest", version(1, 19, 1)))
    .include(dependency("org.pitest", "pitest-command-line", version(1, 17, 4)))
    .include(dependency("org.pitest", "pitest-junit5-plugin", version(1, 2, 2)))
    .include(dependency("org.pitest", "pitest-testng-plugin", version(1, 0, 0)));
```
