Testing

• Run tests with cargo ci check.

Integration tests

There are special test cases in the code base that try to interact with a service run in the test environment. These tests only run when the respective service is started.

Those tests are flagged as such using the crate test-with and assume the presence or absence of an environment variable:

• The following test is only run if the environment variable OPENDUT_RUN_<service-name-in-upper-case>_INTEGRATION_TESTS is present:

  #![allow(unused)]
  fn main() {
  #[test_with::env(OPENDUT_RUN_KEYCLOAK_INTEGRATION_TESTS)]
  #[test]
  fn test_communication_with_service_works() {
      assert!(true);
  }
  }

See Run OpenDuT integration tests for details.

Running tests with logging

By default, log output is suppressed when running tests. To see log output when running tests, mark your test with the #[test_log::test] attribute instead of the standard #[test] attribute, for example: rust #[test_log::test] fn it_still_works() { // ... } And set the environment variable RUST_LOG to the desired log level before running the tests. To see all log messages at the debug level and above, you can then run: shell RUST_LOG=debug cargo ci check
