Usage

From source file:demo.ServerRunning.java

@Override
public Statement apply(final Statement base, FrameworkMethod method, Object target) {

    // Check at the beginning, so this can be used as a static field
    Assume.assumeTrue(serverOnline.get(port));

    RestTemplate client = new RestTemplate();
    boolean followRedirects = HttpURLConnection.getFollowRedirects();
    HttpURLConnection.setFollowRedirects(false);
    boolean online = false;
    try {/*ww  w  .  j a v  a2  s .co  m*/
        client.getForEntity(new UriTemplate(getUrl("/info")).toString(), String.class);
        online = true;
