Bug description
Given the following JUnit Jupiter v6.1.3 test:
package com.example.project;
import org.junit.jupiter.api.Nested;
import org.junit.jupiter.api.Test;
import org.junit.jupiter.params.Parameter;
import org.junit.jupiter.params.ParameterizedClass;
import org.junit.jupiter.params.ParameterizedTest;
import org.junit.jupiter.params.provider.ValueSource;
@ParameterizedClass
@ValueSource(ints = { 1, 2 })
class CalculatorParameterizedClassTests {
@Parameter
int i;
@ParameterizedTest
@ValueSource(ints = { 1, 2 })
void parameterizedTest(int j) {
}
@Nested
@ParameterizedClass
@ValueSource(ints = { 1, 2 })
class Inner {
final int j;
Inner(int j) {
this.j = j;
}
@Test
void regularTest() {
}
}
}When running the regularTest with Surefire 3.6.0
mvn test -D'test=CalculatorParameterizedClassTests$Inner#regularTest'Surefire will execute 4 tests:

Looking at the changes made to the TestPlanScannerFilter in a35e23b there seems to be a misunderstanding. The collectClassNames method assumes that all candidates will be in the test plan if they're discovered. This is not necessarily the case. They may be registered dynamically by one of their parent containers.
