This directory (integration_test) contains all the source code and scripts for the integration test framework and tests.

The main components are:

  • Test framework (src/java/.../(core, common))

    • this forms the core framework which ensures the output of the topology is converted to json, and uploaded to the test server. It also provides helper spouts and bolts which are commonly used by tests.
  • Test topologies (src/java/.../topology)

    • Test topologies make use of the above framework library to test heron functionality. Only this section needs to be touched to add any new tests.
  • Test runner (src/python/test_runner)

    • Test runner picks up the test topologies, launches them on aurora, polls for the actual test results (from the http server), compares that with expected results and kills the topology.
  • Test http server (src/python/http_server)

    • a simple http server (launched as an aurora job) to host the integration test results Test topologies post the result, and test runner gets the result.
  • Local test runner (src/python/local_test_runner)

    • Local test runner launches topologies locally, and polls for the actual results (from the local file system).

To run integration tests on your mac first run the following to build the test package and install the heron client:

  bazel build --config=darwin integration_test/src/...
  bazel run --config=darwin -- scripts/packages:heron-client-install.sh --user
  bazel run --config=darwin -- scripts/packages:heron-tools-install.sh --user

To run the local integration tests on your mac run the following from the heron repo's top dir:

  ./bazel-bin/integration_test/src/python/local_test_runner/local-test-runner

To run just a single test include the module and test class:

  ./bazel-bin/integration_test/src/python/local_test_runner/local-test-runner test_template.TestTemplate
