void testBar() {
def ctrl = new FooController()
def testParams = ...
ctrl.params.putAll(testParams)
ctrl.bar()
...
}
Different outcomes are expected from the call to the action:
Redirection
If redirection is expected, the redirected URL can be obtained from
ctrl.response.redirectedUrl. Keep in mind that unless GRAILS-4270 is resolved, you will have to make sure that the controller name is specified in the parameter list of redirect(). For example,
def index = {
redirect(action: 'list', params: params)
}
won't work. You need to change it to:
def index = {
redirect(controller: 'foo', action: 'list', params: params)
}
A View Is Rendered
If a view is expected, the parameters passed to
render() is actually stored in Spring's ModelAndView object. E.g. if you have the following statement in your controller:
render(view: 'show', model: [ fooInstance: foo ])
You can access foo via:
def foo = ctrl.modelAndView.model.fooInstance
Text Is Rendered Directly
If the action renders some texts directly, the texts can be accessed by
def text = ctrl.response.contentAsString
A Map Is Returned
If a map is returned, as is the case for the scaffolded list action, you can access the map like this:
def map = ctrl.list()
