Grails Spock integration test example?

[David Hay]

Hi,

 

Using Grails Spock plugin for 2.0.3.  Unit tests are running fine, but struggling to set up integration tests.

 

I believe I should extend IntegrationSpec, correct?

 

Is anything autowired for me?  for example if I need a service, do I just declare it, or do I need to new it up?

 

Also, what about integration testing controllers, so I can test the whole stack?  How do I access the request and add a param to it?

 

Many thanks

 

David

If you need auto wiring and data isolation, yes.

Yes, just declare it.

See the testing controllers section of http://grails.org/doc/latest/guide/testing.html#integrationTesting

It's the same, except you extend IntegrationSpec. I'm sorry I don't have more complete examples for you on hand.

Hi Luke,

 

Thanks for the feedback!  More questions inline...

Great - I since got it working well for a spock integration test - the service is autowired beautifully :)

Here's where I am stills struggling.  I created a TestController, and a TestControllerSpec.groovy under test/integration:

 

package ccs

grails.plugin.spock.IntegrationSpec;

class

TestControllerSpec extends IntegrationSpec {

   def

testController

   def setUp = {

       println controller

       println

testController

   }

   def "test controller exists" () {

      setup:

      println

testController

      when:

      1 == 1

      then:

      true

   }

}

However, both controller and testController are always null.

I'm at a loss - this should work, right?  Can you see anything I'm missing?  Can you point me to where to start to debug this?

thanks,

David

You should create a controller like this :

def yourController = new yourController()

Then add the params and other required into the created controller variable like this : 

yourController.params.something = "your params details"

Hope it helps!

[David Hay]

That works.  But I'm still confused as to why the controller is not autowired.

 

any ideas?

I think you need to put the @TestFor(TestController) annotation on the class to get the autowired controller instance. We haven't had any problems getting a reference to the controller.

Thanks, Jonathan.

 

So, I added the @TestFor(TestController), and I got the following error:

        at org.spockframework.util.ReflectionUtil.invokeMethod(ReflectionUtil.java:176)

 

This is an *integration* test - I believe @TestFor is only for unit tests?

 

Are you able to get the Controller injected in an Integration test which extends IntegrationSpec?

 

thanks,

 

David

I'd find it odd to add @TestFor annotations on an integration test.

As for obtaining an instance of a controller remember that Grails uses property name matching to decide if it should inject a dependency. As I have no idea what name Grails registers the controllers with I have always simply injected the grailsApplication bean and then used that to call grailsApplication.context.getBean(MyController)

Never put @TestFor on a Integration test. Even though it is not explicitly
mentioned in Grails documentation @TestFor annotation is for unit test cases
only.

I found it odd too that DI does not work for Controller. But, at this
moment I have done
def controller = new MyController()

Cheers,
Abhijith
