I have a sandbox org where I've created a trigger that calls another class containing a future method for final HTTP request. I have also created a test class and MockHttpRequest for it which is able to pass both the classes well above 90%. Now, the overall code coverage is still showing only 39% as it is also showing the result for two explicit classes(that I've not created in this test Org). The two classes are namely:
So my question is, do I need to cover test cases for these two classes as well before actual deployment, or should I just ignore these additional classes as I have no knowledge of them?
