OCMock does not mock class included via Cocoapods

Question

I'm using OCMock to mock DataFetcher class:

id dataFetcherMock = OCMClassMock([DataFetcher class]);
OCMStub([dataFetcherMock fetchSetupForCompany:[OCMArg any]
                                   completion:[OCMArg any]]).andCall(self, @selector(fetchSetupForCompany:completion:));

It was working fine when DataFetcher was a part of the project. But then we moved DataFetcher to a private Cocoapods. And the mocking stopped working. Method defined in andCall just never called anymore.

Can OCMock be used to mock classes added via cocoapods? How can I make it work?

Answer 1

I found that the problem was with the way I included testing target in pod file. What I had was:

target 'Service' do
    pod 'MTDates'
    pod 'libextobjc'
    pod 'DataFetcher'

    target 'ServiceTests' do
        pod 'OCMock'
        pod 'OHHTTPStubs'
    end
end

This resulted in DataFetcher class being linked to both target and thus it was duplicated in runtime.

I changed to

target 'Service' do
    pod 'MTDates'
    pod 'libextobjc'
    pod 'DataFetcher'
end

target 'ServiceTests' do
    pod 'OCMock'
    pod 'OHHTTPStubs'
end

This resolved the problem.
