Question 1

How do I test command output with multiple lines in fishtape?

Accepted Answer

Use `string collect` to capture multiline output into a single argument, or collapse newlines with `echo`, as shown in the README examples for comparing sequences.

Question 2

Can fishtape integrate with Jenkins or GitHub Actions?

Accepted Answer

Yes, its TAP-compliant output works with any CI/CD tool that supports TAP, such as Jenkins TAP plugin or custom scripts in GitHub Actions for test result parsing.

Question 3

Is fishtape better than using shunit2 or bats for Fish scripts?

Accepted Answer

Fishtape is Fish-native and simpler for Fish-specific testing, while shunit2 or bats are cross-shell but may require adaptation; choose fishtape for pure Fish ecosystems and others for mixed environments.

Question 4

How to set up test fixtures or cleanup in fishtape?

Accepted Answer

Directly include setup and teardown code in test files using Fish commands, like creating temp directories with `mktemp` and cleaning up, as demonstrated in the README for isolated environments.

Question 5

Does fishtape support running tests in parallel?

Accepted Answer

No, fishtape runs test files sequentially in isolated shells; for parallelism, you'd need to manage multiple fishtape instances manually, which can add overhead.

Question 6

What are the performance implications of fishtape's isolated shells?

Accepted Answer

Each test file spawns a new shell instance, which ensures isolation but may introduce overhead for large test suites, impacting speed compared to in-process runners.
