== Using TestKit

To use the TestKit, include the following in your plugin's build:

.Declaring the TestKit dependency
====
include::sample[dir="snippets/testKit/junitQuickstart/kotlin",files="build.gradle.kts[tags=declare-gradle-testkit-dependency]"]
include::sample[dir="snippets/testKit/junitQuickstart/groovy",files="build.gradle[tags=declare-gradle-testkit-dependency]"]
====

`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.

.UrlVerifierPluginFunctionalTest.groovy
[source,groovy]

The plugin also integrates with <<test_kit.adoc#test_kit,TestKit>>, a library that aids in writing and executing functional tests for plugin code.
It automatically adds the `gradleTestKit()` dependency to the `testImplementation` configuration and generates a plugin classpath manifest file consumed by a `GradleRunner` instance if found.

 * for your test by adding the `--watch-fs` command line argument via {@link #withArguments(String...)}.
 * <p>
 * Please see the Gradle <a href="https://docs.gradle.org/current/userguide/test_kit.html" target="_top">TestKit</a> User Manual chapter for more information.
 *
 * @since 2.6
