Adapt framework for testing, make tests use single transaction and be revertible

[romchellis]

It will be cool if there is an ability to revert changes produced from Spring batch job in test.
I tried to test some job or single step and found that typical Spring approach with idempotent tests using @Transactional doesn't work here. Even if transaction attributes were provided to support existing transaction and validateTransactionState is disabled.
So i would like to use it somehow like this
Expected Behavior

    @Test
    @Rollback
    @Transactional
    void Should_create_batches_for_existing_payments() throws Exception {
        testInvoiceGenerator.generateInvoicesForBatch(invoicesCount);
        var expectedCreatedBatchCount = invoicesCount / batchSize;

        var jobExecution = jobLauncherTestUtils.launchJob();
        int countPaymentBatchCount = countPaymentBatchCount();

        assertThat(jobExecution.getStatus()).isEqualTo(COMPLETED);
        assertThat(countPaymentBatchCount).isEqualTo(expectedCreatedBatchCount);
    }

Current Behavior

There is no way to revert commits made by Spring batch transaction manager, or override transaction behaviour in tests.

Context

Spring batch test

Hi @fmbenhassine ,what do you think about it?
Do you have an ideas how to achieve such testing?
