Integration testing is often optional, but is important for us to test interaction with other systems (and in our terminology this is also lumped with end-to-end tests). These tests are found in the tests/integration directory.
Unlike unit tests, these tests can use real secrets. To test locally, these secrets should be configured as usual and it will make use of your .env.
These are tested regularly by the PyRIT team but not necessarily run every pull request. Here are some general guidelines.
Unit tests should test all scenarios and more is often better. Integration tests should be scoped and be careful to not run too long.
Integration tests can sometimes test end-to-end. But almost always, these should target one scenario.
