-----------------------------------
Summary: 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.
