RegistryBasedServlet Equivalent in Selenium 4 - selenium

With Selenium 3, I was able to create custom servlets that can be configured to be used with Hub and Node.
It was possible to extend org.openqa.grid.web.servlet.RegistryBasedServlet or javax.servlet.http.HttpServlet wtih Selenium 3. But with Selenium 4, I could not find the equivalent class for org.openqa.grid.web.servlet.RegistryBasedServlet.
Please suggest what should be the approach taken with Selenium 4?
public class CustomServlet extends RegistryBasedServlet {
// Selenium 3 example
public CustomServlet() {
super(null);
init();
}
public CustomServlet(Registry registry) {
super(registry);
init();
}
private void init() {
}
}
Example Reference : https://rationaleemotions.github.io/gridopadesham/CUSTOM_SERVLETS.html

Servlets are no longer supported in SG4. They completely reworked the concept so there is no just a hub. Hub is a sort of combination of several different components.
Some of those components can be customized and provided as the custom implementation using dedicated flags like --node-implementation, --distributor-implementation, --events-implementation.
You can find some relevant discussion in Selenium github.

How can I control how many JUnit5 Test Instances are going to be generated in Runtime and apply separate ParameterResolver to each of the instance

I'd like to execute Selenium Grid tests using Maven like this:
mvn verify-Dtest=BaseTest -Dprop.selenium.server.url=http://localhost:4444/wd/hub
-Dprop.browser=chrome
-Dprop.version=80.0.3987.106
I inject ChromeDriver into Test constructor using JUnit5 ParameterResolver interface
#ExtendWith(ChromeRemoteWebDriverParameterResolver.class)
#TestInstance(TestInstance.Lifecycle.PER_CLASS)
public class MultiBrowserDemoTest {
RemoteWebDriver driver;
public MultiBrowserDemoTest(RemoteDriver driver) {
this.driver = driver.getDriver();
}
#SneakyThrows
#Test
public void testGrid() {
driver.get("https://www.google.com/");
WebElement search = driver.findElement(By.name("q"));
search.sendKeys("JUnit5 extensions");
search.submit();
}
#AfterAll()
void tearDown() {
driver.quit();
}
}
It works fine. But I can't see how to implement multi-browser test execution.
Let's say, I want to add multiple browsers -Dprop.browser=chrome, firefox, opera, ie11
I created multiple classes implementing ParameterResolver Interface. But JUnit5 does not let me inject them all into my Test Class. It does not create new instances of Test class either.
I tried to use TestInstanceFactory to create new Instances of my Test class and apply separate implementation of ParameterResolver interface, but it did not work for me.
End Result: I can run the same test in multiple browsers in parallel using Selenium Grid and only one Test Class that I will be able to instantiate multiple times with separate webdriver.
If I understood your scenario correctly, what you are asking for is support for what we call "parameterized containers" (i.e., something analogous to #ParameterizedTest but at the class level), which does not exist yet in JUnit Jupiter.
See JUnit Jupiter issues #871 and #878 for details.

How to access test method annotations from a TestExecutionListener

I'm trying to port Test Management For Jira JUnit Integration to JUnit5. This module generates a JSON report of the test run and associates the results with Jira tickets by using annotations on the test methods, example.
From the TestExecutionListener I'm not sure what the best approach to retrieve the TestCase annotation is.
I looked at Reflection using the TestIdentifier.getSource and doing manipulations to rebuild the method signature and extracting the annotation from there but the approach felt clumsy.
I came across this post Allow extensions to register TestExecutionListeners which proposed the following:
Proposal: Have your extension publish the WebDriver bean's session id, e.g.
String sessionId = ...;
extensionContext.publishReportEntry("webDriverSessionId", sessionId)
In your TestExecutionListener, implement reportingEntryPublished and store it in a Map with the TestIdentifier as a key. In executionFinished report the test outcome along with the value from this Map.
This approach looks promising but I want to make sure there isn't another way that doesn't require both an extension and a test execution listener. Is there a way to retrieve test method annotation information directly in the TestExecutionListener?
#Alex, the following might be used inside the listener...
((MethodSource) testIdentifier.source).javaMethod.getAnnotation(TestCase.class)
Seems like you can't get test annotation from TestExecutionListener but instead you can implement TestWatcher or e.g AfterEachCallback and get custom annotation value like that:
import org.junit.jupiter.api.extension.AfterEachCallback;
import org.junit.jupiter.api.extension.ExtensionContext;
import org.junit.jupiter.api.extension.TestWatcher;
public class MyExtention implements TestWatcher, AfterEachCallback {
#Override public void testSuccessful(ExtensionContext context) {
if (context.getElement().isPresent() && context.getElement().get().isAnnotationPresent(MyCustomAnnotation.class)) {
int val = context.getElement().get().getAnnotation(MyCustomAnnotation.class).value();
// Report on success
}
}
#Override public void afterEach(ExtensionContext context) throws Exception {
if (context.getElement().isPresent() && context.getElement().get().isAnnotationPresent(MyCustomAnnotation.class)) {
int val = context.getElement().get().getAnnotation(MyCustomAnnotation.class).value();
// Report each
}
}
}

Serenity BDD with jUnit how to inject steps into setup method?

I am working on a test framework which is using Serenity, Selenium and jUnit. I have some tests which depend on user authentication. Basically I have to repeat all login steps for each test. I wanted to move these steps to a #Before method, but it seems that Steps are not being initialized in a method which is not annotated as #Test... See the code snippet below, AuthSteps instance is not being initialized.
Which are my options?
#RunWith(SerenityRunner.class)
public class MyTests extends AbstractTest {
#Managed(driver = "firefox", uniqueSession = false)
#Steps
AuthSteps auth;
#Before
public void authSetup() {
if (!authenticated){
auth.login();
//a lot of other things
}
}
#Test
public void mytest(){
//do test related stuff
}
They do. Steps will run with either #BeforeClass, #Before, #Test and so on. It seems that your if (!authenticated) statement might be excluding execution of your auth.login() step.
There's certainly not enough code provided here (like what is boolean authenticated)to clearly examine your issue, but I hope this answer helps you.

Implementing the Page Object Model

I am building a test automation project using Perl and Selenium. I am using the Page Object Model. I am somewhat unsure about where the Selenium driver would fit into the implementation of the page object model.
Should each page object 'have' a driver ? The way I am thinking is that each page object represents a set of services that the page offers to a user. With this concept in mind , a page object does not have a 'has-a' relationship with a driver. A page object interacts with a driver. However, I am still looking for suggestions. Should I have the driver as part of each page object in the web-application?
Thanks!
This answer won't be any much different from #zodvik, and your thought process, but is another optional approach. Instead of passing the driver around, you can create an abstract class that each page object can then inherit from. From the abstract class, can also contain some common functional methods that you will find yourself often using.
This is at least how I do it in Java language.
I always include driver as part of every Page Object. The way I thought about driver was that it represents the state of the current page. It gives access to the URL, Page Source, etc.
Now, each page has a a current URL, a page source code, a page title which are all accessible through the driver.
In the way, I implemented the framework. I used the driver in the commonFactory.class that contains commonly used elements. Each page was implemented as a child class of the commonFactory.class. so you don't have to implement the driver in each and every class. Since the driver is independent of the test scenarios it's better to have it in a separate way.
As I understand, there are No set rules/standards for implementing POM.
However, the general thumb rule is to create a BaseTest and BasePage class in your Framework where each respective webpage (like Login) will represent by its PageClass(LoginPage).
Similarly, all your Page classes will extend your BasePage and all tests will extend your BaseTest class.
Below is a rough idea of its implementation ->
public class BaseTest{
#BeforeSuite()
setupMethod(){
initialize your WebDriver here
}
}
------------------------------------------
public class BasePage {
//create constructor
public BasePage(WebDriver driver) {
this.driver = driver;
this.wait = new WebDriverWait(this.driver, Duration.ofSeconds(TIMEOUT));
PageFactory.initElements(new AjaxElementLocatorFactory(this.driver, TIMEOUT), this);
}
//other common methods which can be utilized in your respective child Page classes
}
----------------------------------------------------
public class LoginPage extends BasePage {
//Your Locators and Weblelements
private static final LOGIN_ID = "login";
//Constructor to supply webdriver
public LoginPage(WebDriver driver) {
super(driver);
}
//your action methods
public void loginToApp(){
driver.findbyelement(By.ID(LOGIN_ID)).click
}
}
----------------------------------------------------
public class LoginTest extends BaseTest{
public LoginPage login;
BeforeAll()
{
login = new LoginPage(driver);
}
#Test
public void verifyLogin(){
login.loginToApp();
}
}

Which eclipse plugin implements Ctrl+PageDown or M1+PageDown

I am learning eclipse plugin development and a great deal of learning can be done by looking at the implementation of an existing builtin plugin itself.
While I was looking for a shortcut to switch between tabs I found this --> Eclipse HotKey: how to switch between tabs?
However I am not able to search the command /key binding/ Handler class that actually implements the Ctrl+PageDown key binding.
Similarly, I was able to find the key binding and the command of of M3+PAGE_DOWN (ALT+PAGE_DOWN) in plugins/org.eclipse.ui_some_version.jar (org.eclipse.ui_3.103.0.v20120705-114351.jar in my case) but not the Handler.
How can I find these out? Which plugin should I refer to?
Those commands get handled programatically inside
org.eclipse.ui.part.MultiPageEditorPart.
Good tools for analysing the origin of elements are the "Plug-In Registry" View, the "Plug-In Spy" and Google.
You can find the handler in org.eclipse.ui.workbench (see class org.eclipse.ui.part.MultiPageEditorPart)
The handler is defined programmatically and not declaratively:
public abstract class MultiPageEditorPart extends EditorPart implements IPageChangeProvider {
private static final String COMMAND_NEXT_SUB_TAB = "org.eclipse.ui.navigate.nextSubTab"; //$NON-NLS-1$
private void initializeSubTabSwitching() {
IHandlerService service = (IHandlerService) getSite().getService(IHandlerService.class);
service.activateHandler(COMMAND_NEXT_SUB_TAB, new AbstractHandler() {
// ...
}
});
}
