CollapseConsecutiveAssertThatStatements does not work on Integers (possibly only on Lists?)

[timo-abele]

What version of OpenRewrite are you using?

I am using the latest as of 2024-09-20

How are you running OpenRewrite?

Gradle by editing build file, confirmed by tests on this repository:

• AssertJ assertions not collapsed on Integer #604

What is the smallest, simplest way to reproduce the problem?

• see here: AssertJ assertions not collapsed on Integer #604

in short:

                      Integer i = 1+1;
                      assertThat(i).isNotNull();
                      assertThat(i).isEqualTo(2);

What did you expect to see?

                      Integer i = 1+1;
                      assertThat(i).isNotNull().isEqualTo(2);

What did you see instead?

no change

What is the full stack trace of any errors you encountered?

Context

The existing test are all on Lists, so maybe the recipe currently only works on those and other types need to be enabled in general.

Are you interested in contributing a fix to OpenRewrite?
