Grails Testing problem

[sachin burange]

Hello guys,
I am testing the cotrollers.

Following is the scenario.

A class extends GrailsUnitTestCase class.
Following is the setup method inside it.

void setUp() {
super.setUp()
instance = controllerClass.newInstance()
assertNotNull("No instance found", instance)
String logicalName = controllerGrailsClass.logicalPropertyName
this.metaClass."get${logicalName[0].toUpperCase() + logicalName[1..-1]}" = {-> instance }
['request', 'response', 'session', 'params'].each { field ->
this.metaClass."get${field[0].toUpperCase() + field[1..-1]}" = {-> instance."${field}" }
}
['view', 'viewName', 'model'].each { field ->
this.metaClass."get${field[0].toUpperCase() + field[1..-1]}" = {-> instance.modelAndView."${field}" }
}

}


I am writing test case for render it was sucessful. but when i call redirect testcase it was throwing me follwing exception

Unable to create URL for mapping [/(*)/(*)?/(*)?] and parameters [{payGatewayParam=PayGatewayParam : 1, action=gatewayStatus}]. Parameter [controller] is required, but was not specified!

i am missing somthing in while setting up ?

Hi Sachin,

Have you tried using the mockController method? It looks like you are trying to mock a lot of behaviour yourself, which may be confusing the issue. If you are already extending GrailsUnitTestCase you can do the following:

class MessageControllerTests extends GrailsUnitTestCase {

    void setUp() {
        super.setUp()
        mockController(YourController) //this will set up the mocked behaviour on the MetaClass
    }

    void testCreateViewIsRenderedIfTheMessageDoesNotValidate() {
        def controller = new YourController() //this will create a controller with all the necessary mocked behaviour

        controller.anAction() //here you are executing the action you need to test

        assertEquals('success', controller.renderArgs.view) //here you are verifying that the action called render( view: 'success' )
    }
}

When a controller is mocked in this way the arguments that your code passes to the render and redirect methods are available through the renderArgs and redirectArgs properties. You can also get access to the various scopes (request, flash, session) to check the contents.

There is of course, quite a good example of this, using controllers, domain classes and services, in Chapter 6 of my book!

Cheers,
Jon.

Thanks dear. It get solved.
prviousely my service method was returning
redirect(action: list)
because of this error was coming then i replaced above with below

redirect(controller:"controllername",action: list)
