Test the following new features:
The three issues can really only be tested in combination.
FLINK-19316 is done but missing documentation.
Write an example that uses a (new) FileSource, a (new) FileSink, some random transformations
Run the example in BATCH mode
How ergonomic is the API/configuration?
Are there any weird log messages/exceptions in the JM/TM logs
Maybe try sth that doesn't work on BATCH execution, such as iterations/feedback edges.
When testing a feature, consider the following aspects:
- Is the documentation easy to understand
- Are the error messages, log messages, APIs etc. easy to understand
- Is the feature working as expected under normal conditions
- Is the feature working / failing as expected with invalid input, induced errors etc.
If you find a problem during testing, please file a ticket (Priority=Critical; Fix Version = 1.12.0), and link it in this testing ticket.
During the testing, and once you are finished, please write a short summary of all things you have tested.
