JarCastingatrium-gradle-testkit 
Atrium assertions to test Gradle plugins with TestKit.
Example
Here is how you can use this library to test Gradle plugins. The example uses Spek with spek-testfiles. You can see the whole example in the example-project folder.
object KotlinPluginSpek: Spek({
val testFiles = testFiles()
val projectDir by memoized(SCOPE) { testFiles.createDirectory("testProject") }
describe("run") {
it("compiles the Kotlin code and runs it") {
val runResult = GradleRunner.create()
.forwardOutput()
.withProjectDir(projectDir.toFile())
.withArguments("run")
.build()
expect(runResult) {
task(":compileKotlin").wasSuccessful()
task(":classes").wasInvoked()
output.contains("Hello World!")
}
}
}
beforeGroup {
/* set up the gradle project */
}
})
