This repository houses StreamSets Test Framework (STF) tests for StreamSets Data Collector.
To run tests, install the StreamSets Test Framework and then, after cloning this repository,
cd into it and execute stf test. By default, this will attempt to run all tests using
the default SDC version. If you're just trying STF out for the first time, it might be a better idea
to limit your test run to a module with no external dependencies (e.g. stage.test_dev_stages). It's also
usually desirable to specify an SDC version and add -s to send test output to the console.
Putting it all together:
$ git clone https://github.com/streamsets/datacollector-tests.git

- datacollector/: Tests that exercise DataCollector-wide functionality (e.g. classpath validation).
- fault/ (in progress): Tests that exercise product resilience in the presence of injected faults.
- package/ (in progress): Packaging tests.
- performance/ (in progress): Tests that focus on product performance using the pytest-benchmark plugin.
- pipeline/: Tests that exercise end-to-end workflows (e.g. the drift synchronization solution) or pipeline-level functionality. If the pipeline you want to test is complex, it should probably have a test here.
- resources/: Resources to be used within tests (e.g. protobuf object schema).
- stage/: Tests that attempt to isolate functionality of individual stages. This tends to be in the form of
<dev origin> >> <stage>tests for destinations,<dev origin> >> stage >> <trash>tests for processors, or<stage> >> <trash>tests for origins. - upgrade/: Legacy SDC pipeline upgrade tests. Unless there's a really good reason to do so, don't add new tests to this folder.
