I need to test two functions inside another function. See the example below: def parent(): a = A() b = B(a) c = C(b) d = D(c) e = E(d) f = F(e) g = G(f) h = H(g) return h I want to test only the interactions between A() and B(). The rest does not matter to me. I could split both functions into a second one, but it is not trivial. If I test the function parent(), I need to mock the functions C() to H(). So, if the b variable reaches the expected value, I could end my test with a success. I don't see a suitable solution for this. Even if I use pytest.raises, it is more dedicated to test behaviors than partial tests. Continue reading...
