Grails controller test containing model statements when rendering a template?

Using Grails 2.1.0

It seems to do this from the controller:

render(view: "someView", model: [modelEntry: "hello"])

allows me to do this in unit test for this controller:

controller.method() 
assert model.modelEntry == "hello"

However, if I change the controller, do this:

render(template: "someTemplate", model: [modelEntry: "hello"])

Now the model instance in the test is an empty array. I understand this a lot, and most of the solutions seem to be for Grails 1, often involving an object modelAndView(which is not in my test) or renderArgs(ditto).

The only solution I found was to manually override the views in the test, for example:

views['_someTemplate.gsp'] = '${modelEntry}'

and then make statements about the string. But I do not like this solution because it:

  • requires the test to know the template file name
  • makes it difficult to test model records that do not have good toString () methods
  • .
