| 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 `get`s the result. |
| |
| * Test launcher (scripts/test_launcher.sh) |
| - this scripts is a helper to launch and kill the above components. |
| |
| To run the tests on jenkins, |
| Go to "https://ci.twitter.biz/job/heron-staging-integration_tests/" |
| Select 'Build With Parameters' |
| Enter the branch your want to test against, and click 'Build' |
| |
| Jenkins job will make an E release with pkgrole='jenkins', and pkgname='heron-integration-test', |
| and then launch the tests with this release. |
| |
| To run the tests locally (although not that useful), |
| make |
| cd build/integration-test |
| ./scripts/test_launcher.sh local |
