I am a gradle novice searching for help here. I got my tasks up and running and followed the examples for functional tests.
My test task fails with the exception path may not be null or empty string. path='null'

My docker container starts an application and keeps the foreground open, maybe this kind of leads the test to a unknown result?

Here is the gradle snippet.

task build_DockerImage(type: DockerBuildImage) {
	group 'Docker'
	description "Builds the docker image: ${dockerTag} locally"
	if(project.name.equals(rootProject.name) ) {
		dependsOn copy_ImageSource
	}
	inputDir = file("${rootProject.projectDir}/ci/images/${project.name}")
	tag = "azeti/${project.name}:${dockerTag}"
}

task push_DockerImage(type: DockerPushImage, dependsOn: build_DockerImage) {
	description 'Pushes the docker image into the azeti DockerHub, requires dockerRegistryUsername and dockerRegistryPassword to be set'
	group = 'Docker'
	imageName = dockerTag
}

task create_DockerTestContainer(type: DockerCreateContainer) {
		dependsOn build_DockerImage
		env = [ "foo=bar" ]
		targetImageId { build_DockerImage.getImageId() }
}

	task start_DockerTestContainer(type: DockerStartContainer) {
		dependsOn create_DockerTestContainer
		targetContainerId { create_DockerTestContainer.getContainerId() }
}

task stop_DockerTestContainer(type: DockerStopContainer) {
		targetContainerId { create_DockerTestContainer.getContainerId() }
}

task test_DockerContainer(type: Test) {
	group 'test'
	description 'Builds the image, creates and runs the container of it and tests against the return code for successful execution.'

	dependsOn start_DockerTestContainer
	finalizedBy stop_DockerTestContainer
}

And the stacktrace (stripped the head a little bit for sake of readability):

@seb-koch is this the output from gradle build with -s switch? If not can you post it here?

BTW, this setup won't work as you would expected, because test_DockerContainer task will start the container and immediately stop it during task finalization. You probably need to use DockerWaitContainer task to wait for container to do its job.

@orzeh i posted the stacktrace initially (--stacktrace). I will try DockerWaitContainer asap. thanks so far.

ok, I know what is causing the problem.

test_DockerContainer task is of type Test and you probably didn't apply java plugin to this project and some configuration is invalid. Remove the type declaration and it should work:

task test_DockerContainer() {
	group 'test'
	description 'Builds the image, creates and runs the container of it and tests against the return code for successful execution.'

	dependsOn start_DockerTestContainer
	finalizedBy stop_DockerTestContainer
}

Thanks a lot! This was the missing piece. The test now runs fine.
