krmahadevan / GroupPrinter.java
Last active July 2, 2016 08:41
A Sample Suite Listener which can retrieve the names of all methods that are part of a group.
public static class GroupPrinter implements ISuiteListener {
@Override
public void onStart(ISuite suite) {
String groupName = System.getProperty("groupName", "all");
List<ITestNGMethod> allMethods = suite.getAllMethods();
List<ITestNGMethod> filteredMethods = new ArrayList<>();
for (ITestNGMethod method : allMethods) {
if (Arrays.asList(method.getGroups()).contains(groupName)) {
filteredMethods.add(method);

Created March 4, 2016 04:37
A sample that shows how to weave a html page in runtime using Javascript and view it on a browser. This technique can be used in cases where one has to open a saved page in a remote execution environment (such as SauceLabs)

Created September 26, 2015 04:59
This example shows how to leverage a TestNG listener and trigger test skips if one of the test failed.
@Listeners (SkipRestOfTheTestsIfFailuresAreSeen.AbortRemainingTestsListener.class)
public class SkipRestOfTheTestsIfFailuresAreSeen {
@Test
public void testMethod1() {
Reporter.log("testMethod1() being executed", true);
}
@Test
public void testMethod2() {

Created February 25, 2013 10:25
This is a sample that shows how to use "IMethodInterceptor" in TestNG to order your tests. In this example I am ordering the tests based on their method names.

Created January 27, 2013 18:43
A simple servlet which basically issues a System.exit() when invoked. This servlet would have to be injected into the node [not the Grid] so that it can help in terminating the node.
import java.io.IOException;
import javax.servlet.ServletException;

krmahadevan / MyRemoteProxy.java
Created January 27, 2013 18:27
This is a custom Proxy. This proxy when injected into the Grid, starts counting unique test sessions. After "n" test sessions, the proxy unhooks the node gracefully from the grid and self terminates gracefully. The number of unique sessions is controlled via a properties file : "mygrid.properties".

This is a standalone java application that can continuously monitor a another JVM and if the JVM crashes or exits it can re-spawn it again.
