Ben Chambers commented on BEAM-85: ---------------------------------- One possibility would be to use an `@Rule` instead. for instance: ```java @Rule public TestPipelineRule testPipeline; ... Pipeline p = testPipeline.create ... ``` Then the `tearDown` from the rule can validate proper usage. > DataflowAssert (BeamAssert ;) needs sanity check that it's used correctly > ------------------------------------------------------------------------- > > Key: BEAM-85 > URL: https://issues.apache.org/jira/browse/BEAM-85 > Project: Beam > Issue Type: New Feature > Components: sdk-java-core > Reporter: Daniel Halperin > Assignee: Davor Bonaci > > It is important that assert is applied to pipeline before the pipeline is > run, otherwise it does not actually execute the test. > This code should throw an assertion error or fail in some other way. > ```java > { > Pipeline p = TestPipeline.create(); > PCollection<Boolean> value = p.apply(Create.of(Boolean.FALSE)); > p.run(); > DataflowAssert.thatSingleton(value).isEqualTo(true); > } > ``` > but it would pass silently. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
