SpringBoot ActiveProfiles with comma separated profiles does not work in release 2.3.2

the following code will pass in release 2.2.9 but in 2.3.2

@SpringBootTest
@ActiveProfiles("test1,test2")
@ContextConfiguration(classes = SpringBootTestWithActiveProfilesWithCommaTests.class)
public class SpringBootTestWithActiveProfilesWithCommaTests
{

    @Autowired
    private Environment environment;

    @Test
    void getActiveProfiles()
    {
        assertThat(this.environment.getActiveProfiles()).containsOnly("test1", "test2");
    }
}

Thanks for the report. I am not sure yet what was the change that led to this but the test above looks wrong to me if you intend to enable two profiles. It should rather be @ActiveProfiles({"test1", "test2"}). When I do that change, this test passes for me.

The release notes for 2.3 also has a dedicated section about this. Please make sure to review them when upgrading.
