No runnable methods while running Test case run as

I have created test case for a eclipse RCP application:

@Test
public final void testIsCacertsFileExist() {
    try {//URL url = new URL("https://server/web/services/WO");
    // System.out.println(url.getPort());
    URL url1 = new URL("http://server/web/services/WO");
    System.out.println(url1.getPort());
    CertificateHandler.addCertToKeyStore(
        "http://server/web/services/WO");", 443);
    File file = new File("cacerts");
    Assert.assertTrue(file.exists());
    readCertificates(file);
} catch (ConnectionException e) {
    fail(e.getMessage());
} catch (MalformedURLException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
}
}

I am using @Test annotation. In Eclipse I am running run as > Junit Plugin test. Still I am getting below error:

java.lang.Exception: No runnable methods

Here is the solution to my question. I delete the project from workspace. Created newly checkout the code from repository. junit-4.3.1.jar added in the class-path. Opened the plugin.xml in dependency tab. under required plugins click on add button type in the search org.junit. add the latest one in my eclipse (Indigo) org.junit(4.8.2.v4_8_2_v20110321-1705) and it display as org.junit(4.8.2).

Modification in files: .classpath - added "junit-4.3.1.jar" entry MANIFEST.MF - Require-Bundle: ,org.junit;bundle-version="4.8.2" got added due to change in plugin.xml.

Thanks, Anand

Is this code itself also contained either in a test plugin or a plugin fragment (extending the plugin to be tested)? You cannot just have a Java class in a normal Java project for a plugin test.
