TestsShouldIncludeAssertions didn't treat assumptions as anything special, so a test guarded by an assumption but without an assertion got its body wrapped in assertDoesNotThrow:

@Test
void onLinux() {
    assertDoesNotThrow(() -> {
        assumeTrue(isLinux());
        service.start();
    });
}

assertDoesNotThrow catches the TestAbortedException a failed assumption throws, so a test that should have been skipped on other platforms now fails there.

The recipe now leaves a test unchanged when its body (or a helper it calls in the same class) calls JUnit Jupiter Assumptions, JUnit 4 Assume, or AssertJ Assumptions. The description mentions this too.
