Authoring New Tests

Integration tests live in the twiggy/tests directory:

├── expectations
├── fixtures
└── tests.rs
  • The twiggy/tests/tests.rs file contains the #[test] definitions.

  • The twiggy/tests/fixtures directory contains input binaries for tests.

  • The twiggy/tests/expectations directory contains the expected output of test commands.

Updating Test Expectations

To automatically update all test expectations, you can run the tests with the TWIGGY_UPDATE_TEST_EXPECTATIONS=1 environment variable set. Make sure that you look at the changes before committing them, and that they match your intentions!

TIP: You can use git add -p to examine individual hunks when staging changes before committing!
