There’s an excellent Go testing pattern that too few people know. I can teach it to you in 30 seconds. Instead of writing Go tests like this: // The common, unrefined way. username := GetUser() if username != "dummyUser" { t.Errorf("unexpected username: got %s, want: %s", username, "dummyUser") } Write your tests like this, beginning each assertion with if got, want :=: // The underused, elegant way. if got, want := GetUser(), "dummyUser"; got != want { t.Errorf("username=%s, want=%s", got, want) } The if got, want :=: pattern works even better in table-driven tests. Here’s an example from my library for parsing social media handles:
Software bloggers can make the same mistakes for years that prevent readers from discovering their writing. I know because I'm one of them. Over time, I've learned techniques that help some blog posts succeed and the pitfalls that cause others to languish in obscurity.
