Question 1

Which statement passes the "could a stranger check it?" test?

1. Make the API more robust
2. Handle errors properly
3. On a network timeout, retry twice with 1 s then 2 s backoff, then return 503 with a Retry-After header
4. Use clean, idiomatic code

Question 2

What is the main purpose of a non-goals section in a specification?

1. To list future work for the roadmap
2. To give the model and the reviewer a line to point at when the diff goes beyond the request
3. To document known bugs
4. To justify the estimate

Question 3

Why should the tests be written before the implementation when working with an assistant?

1. Because it is faster
2. Because tests written after generation tend to agree with the generated code, including its mistakes
3. Because assistants cannot write tests
4. Because CI requires it

---

Question 4

A newly written test fails with a syntax error in the test file itself. What should happen next?

1. Generate the implementation; the test will be fixed later
2. Delete the test
3. Fix the test first - a test must fail for the right reason before any code is generated
4. Ask the assistant to make the test pass

---

Question 5

During implementation, the assistant says one of the tests is wrong and proposes to change it. What is the correct response?

1. Accept the change; the assistant has seen the code
2. Stop, decide yourself by editing the spec, then update the test, then resume
3. Delete the test and continue
4. Ask the assistant to write a second test that passes

Question 6

Which kind of test gives the least protection against generated code?

1. Behavioural tests that call the endpoint and check the response
2. Example-based tests taken from the spec
3. Property-based tests
4. Mock-heavy unit tests that assert on internal calls
