How retrieve the Retry/Skipped data for Testing purposes [BATCH-2629]

Manuel Jordan opened BATCH-2629 and commented

For Testing purposes I can do the following in peace (in general)

assertThat(jobExecution.getExitStatus().getExitCode(), is("COMPLETED"));
assertThat(jobExecution.getAllFailureExceptions().size(), is(0));
assertThat(jobExecution.getFailureExceptions().size(), is(0));

or

assertThat(jobExecution.getExitStatus().getExitCode(), is("FAILED"));
assertThat(jobExecution.getAllFailureExceptions().size(), is(1));
assertThat(jobExecution.getAllFailureExceptions().get(0).getClass().getSimpleName(),
              is(SkipLimitExceededException.class.getSimpleName()));
assertThat(jobExecution.getAllFailureExceptions().get(0).getMessage(),
              is("Skip limit of '5' exceeded"));

assertThat(jobExecution.getFailureExceptions().size(), is(0));

Seems the API does not provide a way to extract detailed data about Retry and Skip information.

For example: for the Steps X, Y, Z (for each one or individually) how many retries were applied and for what row, same appreciation for Skip. Same about (Retry and Skip) but through a global report from the Steps X,Y,Z. Of course if the Job has one Step, the global is the same than the individual

The listeners works fine only for report purposes and their methods return void. Not sure if the current API and Spring Batch db schema support it for testing.

Thank you.

Affects: 3.0.6, 3.0.7

Start by reviewing the JobExecution API, listener behavior, and Spring Batch database schema mentioned in the issue. Determine whether retry and skip details can be retrieved per step and globally for testing, including counts and affected rows or exceptions; done means the supported API and expected test assertions are clearly defined.
