`GradleRunner` is an API provided by TestKit, which internally uses the Tooling API to execute the build.

The following example applies the plugin to the build script under test, configures the extension and executes the build with the task `verifyUrl`.
Please see the <<test_kit.adoc#test_kit,TestKit documentation>> to get more familiar with the functionality of TestKit.
