Idiomatic Go Testing FAQs

Question 1

Can I automatically generate test scaffolds?

Accepted Answer

Yes, the skill includes access to scripts like gen-table-test.sh which can automatically scaffold the canonical struct, loop, and subtest layout for any Go function.

Question 2

Does this skill support testing Protocol Buffers?

Accepted Answer

Yes, it provides specific guidance for using protocmp.Transform() with cmp.Diff to ensure semantically correct comparisons of proto messages.

Question 3

How should I handle test cleanup and teardown?

Accepted Answer

The skill promotes the use of t.Cleanup() within test helpers. This is more robust than deferred functions because it ensures cleanup happens even if the test fails early or uses t.Fatal().

Question 4

Why does this skill avoid assertion libraries like Testify?

Accepted Answer

This skill follows the Go community and major tech style guides (Google/Uber) which prefer using the standard library and cmp.Diff. This approach leads to more readable, maintainable tests with better diagnostic messages without adding heavy external dependencies.

Question 5

When should I use t.Fatal versus t.Error?

Accepted Answer

Use t.Fatal when a failure makes continuing the test impossible (like a failed DB connection). Use t.Error by default for assertions so that multiple failures can be reported in a single test run.
