Abort/ignore parameterized test in JUnit 5

I have some parameterized tests

@ParameterizedTest
@CsvFileSource(resources = "testData.csv", numLinesToSkip = 1)
public void testExample(String parameter, String anotherParameter) {

    // testing here
}

In case one execution fails, I want to ignore all following executions.

AFAIK there is no built-in mechanism to do this. The following does work, but is a bit hackish:

@TestInstance(Lifecycle.PER_CLASS)
class Test {

    boolean skipRemaining = false;
    
    @ParameterizedTest
    @CsvFileSource(resources = "testData.csv", numLinesToSkip = 1)
    void test(String parameter, String anotherParameter) {
        Assumptions.assumeFalse(skipRemaining);
        try {
            // testing here
        } catch (AssertionError e) {
            skipRemaining = true;
            throw e;
        }
    }

}

In contrast to a failed assertion, which marks a test as failed, an assumption results in an abort of a test. In addition, the lifecycle is switched from per method to per class:

When using this mode, a new test instance will be created once per test class. Thus, if your test methods rely on state stored in instance variables, you may need to reset that state in @BeforeEach or @AfterEach methods.

Depending on how often you need that feature, I would rather go with a custom extension.
