Ben Johnson's tip. Suppose you Finally, the code to test the crashing part of the previous function would be the following: package foo Errorf("expected test code; got %q (len %d)", body, len(body)) } } func TestNoExistBinary(t *testing. I have read many blogs, watched talks and Don't use frameworks.
