Expected behavior
A clear and concise description of what you expected to happen.

        jobLauncherTestUtils.setJob(job);
        var result = jobLauncherTestUtils.launchJob();
        Assertions.assertThat(result.getJobParameters().getString("year")).isEqualTo(DateTimeFormatter.ofPattern("yyyyMM").format(LocalDateTime.now()));
        Assertions.assertThat(result.getStatus()).isEqualTo(BatchStatus.COMPLETED);

Minimal Complete Reproducible example
Please provide a failing test or a minimal complete verifiable example that reproduces the issue.
Bug reports that are reproducible will take priority in resolution over reports that are not reproducible.

        jobLauncherTestUtils.setJob(job);
        var result = jobLauncherTestUtils.launchJob(job.getJobParametersIncrementer().getNext(jobLauncherTestUtils.getUniqueJobParameters()));
        Assertions.assertThat(result.getJobParameters().getString("year")).isEqualTo(DateTimeFormatter.ofPattern("yyyyMM").format(LocalDateTime.now()));
        Assertions.assertThat(result.getStatus()).isEqualTo(BatchStatus.COMPLETED);

I'm sorry.
In the case of SimpleJobLauncher, it is thought that it does not depend on parameters.
So, if modification is needed, it seems that JobLauncherTestUtils needs to be modified. Since 5.0.0, the spring launcher test utility seems to be deprecated. What should I do if I am using version 4.3?

JobLauncherTestUtils

How about this modification in JobLauncherTestUtils?

    public JobExecution launchJob() throws Exception {
        JobParametersIncrementer incrementer = this.job.getJobParametersIncrementer();
        if (incrementer == null) {
            return this.launchJob(this.getUniqueJobParameters());
        }
        return this.launchJob(incrementer.getNext(this.getUniqueJobParameters()));
    }

Which cli are you referring to? The CommandLineJobRunner does not use the incrementer unless you specify the -next option. The equivalent API is JobOperator#startNextInstance. SimpleJobLauncher is not designed to start the next instance with the run method since the user gives the parameters and can increment them beforehand if needed.

So, if modification is needed, it seems that JobLauncherTestUtils needs to be modified. Since 5.0.0, the spring launcher test utility seems to be deprecated.

Which deprecated test utility you are referring to?

Please clarify the bug report. I still don't fully understand the issue your are reporting. Thank you upfront.
