How to identify different test cases when parameterizing

Question

When using JUnitParams, I can pass an array of Objects where each element will be used to run a test.

Is there any way to add a name or identification to each of these? So when I run these JUnit test, Eclipse would show the name of each case instead of the 0-n index of the array.

JUnitParams supports custom test names using the @TestCaseName annotation that would accomplish what you want. The annotation allows you to pass a template for the test name and then use indexed parameters in the format {n}.

Heres a very simple example of how that would work:

@Test
@Parameters(...)
@TestCaseName("Test {0} equals {1}")
public void testName(String expected, String actual) {
    assertEquals(expected, actual);
}
