hi, i want to write a test class for controller in which there is a webservice callout.. using webservicemock am getting response as null..confused.how to write test code

apex page

HttpCallouts don't actually work when running tests (nor do Soap callouts).

Use the Test.isRunTest() method to find out if the code being executed is part of a Unit Test. If this call returns true, then return some premade/pre-populated data with some conditions/results you want.

Specifically, I'd probably trap on the oGetPlantSfdcId.ZSD_FM_GET_PLANT_SFDC_ID() callout.

Since I don't know what your objResponse object really looks like, I won't evern try to think of how to popualte it. Suffice to say, if you can trap a real callout, then maybe save the output, that might help as a more plausible seed.

Hope this helps...

Leslie's incorrect in that you should use the WebserviceMock interface for this, as your subject suggests.  It's a best practice to shy away from using Test.isRunningTest at all costs, unless you absolutely have to.  

In order to get WebserviceMock to work, you'll need to create a separate class that implements the WebserviceMock interface as shown in the first example on this page: 
https://www.salesforce.com/us/developer/docs/apexcode/Content/apex_callouts_wsdl2apex_testing.htm

The response.put('response_x', respElement); piece is key, as this tells salefsorce what to expect from the soap callout.

Also key is using the Test.setMock(WebServiceMock.class, new YourWebServiceMockImpl()); in your Test class, which will tell Salesforce to inject your mock response into the unit test instead of performing an actual callout.

Hope that helps.

Stand corrected --> James' way is better.
