---------------------------------
Summary: CoderProperties: Test that the coder doesn't consume more
bytes than it produces
Key: BEAM-372
URL: https://issues.apache.org/jira/browse/BEAM-372
Project: Beam
Issue Type: Bug
Components: sdk-java-core
Reporter: Ben Chambers
Assignee: Davor Bonaci
Priority: Minor
Add a test to CoderProperties that does the following:
1. Encode a value using the Coder
2. Add a byte at the end of the encoded array
3. Decode the value using the Coder
4. Verify the extra byte was not consumed
(This could possibly just be an enhancement to the existing round-trip
encode/decode test)
When this fails it can lead to very difficult to debug situations in a coder
wrapped around the problematic coder. This would be an easy test that would
clearly fail *for the coder which was problematic*.
