`test` - Task (lifecycle)::
Depends on: `runTest__Variant__` that most closely matches the build host
::
Aggregate task of the variant that most closely match the build host for testing the component.

`check` - Task (lifecycle)::
Depends on: `test`
::
Aggregate task that performs verification tasks, such as running the tests.
Some plugins add their own verification task to `check`.

Applying the plugin adds the `buildDashboard` task to your project. The task aggregates the reports for all tasks that implement the link:{groovyDslPath}/org.gradle.api.reporting.Reporting.html[Reporting] interface from _all projects_ in the build. It is typically only applied to the root project.
