--------------------------------
Summary: Support asserting the contents of windows and panes in
PAssert
Key: BEAM-155
URL: https://issues.apache.org/jira/browse/BEAM-155
Project: Beam
Issue Type: Improvement
Components: sdk-java-core
Reporter: Thomas Groh
Assignee: Davor Bonaci
This consists of reifying the output windows and panes, and running asserts
per-window about the contents of panes.
This includes aggregated matching and final pane matching, e.g.
PAssert.that(output).byOnTimePane().hasOutputElements(foo, bar);
// For discarding mode - could have emitted (say) [spam, eggs], [spam], [],
[sausage], []
PAssert.that(output).byFinalPane().hasOutputElements(spam, eggs, sausage, spam);
// For accumulating mode without late data
PAssert.that(output).finalPane().containsInAnyOrder(spam, eggs, sausage, spam);
// For accumulating mode with late data
PAssert.that(output).finalPane().containsInAnyOrder(foo,
bar).mayAlsoContain(baz, rab);
