tests: Avoid use of global mocked server
The meat of this changes is in 'testhelper/http_responses.go' and 'testhelper/client/fake.go'. The rest of the change is bulk generated updates to handle those changes: Create a "FakeServer" instance instead of configuring the global fake: sed -i 's/th.SetupHTTP/fakeServer := th.SetupHTTP/g' $(ag 'th.SetupHTTP' -l) Tear down this instance on test completion: sed -i 's/defer th.TeardownHTTP/defer fakeServer.Teardown/g' $(ag 'defer th.TeardownHTTP' -l) Update calls to the global 'Mux' instance with calls to the FakeServer version: sed -i 's/th.Mux.HandleFunc/fakeServer.Mux.HandleFunc/g' $(ag 'th.Mux.HandleFunc' -l) Update calls to ServiceClient to include a 'FakeServer' parameter: sed -i 's/client.ServiceClient()/client.ServiceClient(fakeServer)/' $(ag -w client.ServiceClient -l) Plus alises for the same: sed -i 's/fake.ServiceClient()/fake.ServiceClient(fakeServer)/' $(ag 'fake.ServiceClient' -l) Update definitions and calls to various MockFoo and HandleFoo helpers - plus lowercase, private variants of same - to include a 'FakeServer' parameter: sed -i 's/\(func Mock\w\+(t \*testing.T\)/\1, fakeServer th.FakeServer/' $(ag 'func Mock\w+\(t \*testing.T' -l) sed -i 's/\(\tMock\w\+(t\)/\1, fakeServer/' $(ag '\tMock\w+\(t' -l) sed -i 's/\(func mock\w\+(t \*testing.T\)/\1, fakeServer th.FakeServer/' $(ag 'func mock\w+\(t \*testing.T' -l) sed -i 's/\(\tmock\w\+(t\)/\1, fakeServer/' $(ag '\tmock\w+\(t' -l) sed -i 's/\(func Handle\w\+(t \*testing.T\)/\1, fakeServer th.FakeServer/' $(ag 'func Handle\w+\(t \*testing.T' -l) sed -i 's/\(\tHandle\w\+(t\)/\1, fakeServer/' $(ag '\tHandle\w+\(t' -l) sed -i 's/\(func handle\w\+(t \*testing.T\)/\1, fakeServer th.FakeServer/' $(ag 'func handle\w+\(t \*testing.T' -l) sed -i 's/\(\thandle\w\+(t\)/\1, fakeServer/' $(ag '\thandle\w+\(t' -l) Finally, there were some manual fixes to handle stuff that the regexes missed.
