copied!<p><strong>This feature has made it into <a href="https://github.com/junit-team/junit/wiki/Download-and-Install" rel="noreferrer">JUnit 4.11</a>.</strong></p> <p>To use change the name of parameterized tests, you say:</p> <pre><code>@Parameters(name="namestring") </code></pre> <p><em><code>namestring</code></em> is a string, which can have the following special placeholders:</p> <ul> <li><code>{index}</code> - the index of this set of arguments. The default <em><code>namestring</code></em> is <code>{index}</code>.</li> <li><code>{0}</code> - the first parameter value from this invocation of the test.</li> <li><code>{1}</code> - the second parameter value</li> <li>and so on</li> </ul> <p>The final name of the test will be the name of the test method, followed by the <em><code>namestring</code></em> in brackets, as shown below.</p> <p>For example (adapted from the unit test for the <code>Parameterized</code> annotation):</p> <pre><code>@RunWith(Parameterized.class) static public class FibonacciTest { @Parameters( name = "{index}: fib({0})={1}" ) public static Iterable<Object[]> data() { return Arrays.asList(new Object[][] { { 0, 0 }, { 1, 1 }, { 2, 1 }, { 3, 2 }, { 4, 3 }, { 5, 5 }, { 6, 8 } }); } private final int fInput; private final int fExpected; public FibonacciTest(int input, int expected) { fInput= input; fExpected= expected; } @Test public void testFib() { assertEquals(fExpected, fib(fInput)); } private int fib(int x) { // TODO: actually calculate Fibonacci numbers return 0; } } </code></pre> <p>will give names like <code>testFib[1: fib(1)=1]</code> and <code>testFib[4: fib(4)=3]</code>. (The <code>testFib</code> part of the name is the method name of the <code>@Test</code>).</p>
