[jira] [Created] (GROOVY-9188) Partial mocking static method calls with Ignore & Demand don't work as expected.

Bryan Stopp created GROOVY-9188:
-----------------------------------

             Summary: Partial mocking static method calls with Ignore & Demand don't work as expected.
                 Key: GROOVY-9188
                 URL: https://issues.apache.org/jira/browse/GROOVY-9188
             Project: Groovy
          Issue Type: Bug
          Components: mocks and stubs
    Affects Versions: 2.5.7
            Reporter: Bryan Stopp


When defining a mockFor on a class with static methods, if you _ignore_ a method which invokes a _demand_ mocked method. The _demand_ is not intercepted.

Here is an example modified from the MockFor documentation:

 
```
import groovy.mock.interceptor.MockFor
class Person {
  static def ignoreMe(foo) { foo }
  static def ignoreMeToo() { ignoreMe('foo') }
  static def ignoreMeThree() { ignoreMe('foo') }
}
def mock = new MockFor(Person)
mock.ignore('ignoreMeToo')
mock.ignore('ignoreMeThree')
mock.demand.ignoreMe { s -> 'baz' }
mock.use {
  assert Person.ignoreMe('foo') == 'baz'
  assert Person.ignoreMeToo() == 'baz'
  assert Person.ignoreMeThree() == 'baz'
}
```
 

Running this will result in a failure as *Person.ignoreMeToo()* returns `foo` instead of `baz`.

Use Case: Mocking nested static method calls. I want to test a particular method. I know/expect that method to invoke another static method on the same class, but I want to mock that one, and return an expected value.
