--------------------------------------
Summary: Make it easier to test runtime-accessible ValueProvider's
Key: BEAM-2644
URL: https://issues.apache.org/jira/browse/BEAM-2644
Project: Beam
Issue Type: New Feature
Components: sdk-java-core
Reporter: Eugene Kirpichov
Assignee: Davor Bonaci
Many transforms that take ValueProvider's have different codepaths for when the
provider is accessible or not. However, as far as I can tell, there is no good
way to construct a transform with an inaccessible ValueProvider, and then test
how it runs with an actual value supplied.
The only way I could come up with is mimicking
https://github.com/apache/beam/blob/master/sdks/java/core/src/test/java/org/apache/beam/sdk/options/ValueProviderTest.java#L202
, which is very ugly.
