Excluding a non param test in parameterized test class

I was able to do something very similar to Matthew Madson answer and found it useful to create a Base Class to encapsulate setup and common helper functions between the single and param tests. This works without using Enclosed.class.

 @RunWith(Suite.class)
 @SuiteClasses({ComponentTest.ComponentParamTests.class, ComponentTest.ComponentSingleTests.class})
 public class ComponentTest {

    public static class TestBase {
        @Spy
        ...
        @Before
        ...
    }

    @RunWith(Parameterized.class)
    public static class ComponentParamTests extends TestBase{
        @Parameter
        ...
        @Parameters
        ...
        @Test
        ...
    }
    public static class ComponentSingleTests extends TestBase{
        @Test
        ...
    }
}

For those who wants the parameters come from java function instead of annotations:

@ParameterizedTest
@MethodSource("provideStringsForIsBlank")
void isBlank_ShouldReturnTrueForNullOrBlankStrings(String input, boolean expected) {
    assertEquals(expected, Strings.isBlank(input));
}

private static Stream<Arguments> provideStringsForIsBlank() {
    return Stream.of(
      Arguments.of(null, true),
      Arguments.of("", true),
      Arguments.of("  ", true),
      Arguments.of("not blank", false)
    );
}

I stuck in this problem while I'm writing test in spring boot MockMvc I simply created two classes in separate java files ( one for ParameterizedTest and other for SingleTest ) and create a suite for them. because inner classes were creating error for static members and and not static members and class.
