Testing the user interface for any application is generally time-consuming when done for each new release. UI test automation is the most common and effective way to simulate the actual user journey and business use-cases for any application.
In this course, you will learn how to design a test automation framework from scratch for automating any web-based application using Java, Selenium, and TestNG. You’ll start by learning the basics of Selenium and TestNG and then move on to learn about build management, logging, and reporting, which are key learnings for any QA engineer or developer. By the end of this course, you will have successfully created a UI test automation framework.

Design a Test Automation Framework with Selenium and Java

# TestNG listeners

There are several interfaces that allow us to change the behavior of TestNG at runtime:

* **`IAlterSuiteListener`** - on implementing this interface, we have method `alter` to alter the test suite
* **`IAnnotationTransformer`** - on implementing this interface, we can alter `@Test`, `@DataProvider`, `@Factory`, ***@Listener*** annotations
* **`IClassListener`** - on implementing this interface, we can call `onBeforeClass` and `onAfterClass`
* **`IConfigurable`** - on implementing the interface, `run` method will be invoked instead of each configuration method found
* **`IConfigurationListener`** - on implementing this interface, we can call methods `onConfigurationSuccess`, `onConfigurationFailure`, `onConfigurationSkip` and `beforeConfiguration`
* **`IDataProviderListener`** - method `beforeDataProviderExecution` and `afterDataProviderExecution`
* **`IExecutionListener`** - `onExecutionStart` and `onExecutionFinish`
* **`IHookable`** - this method has a method `run` and on implementing, `run` method will be called instead of `@Test` method
* **`IInvokedMethodListener`** - on implementing this interface, we have method  `beforeInvocation`, `afterInvocation`, `beforeInvocation`, `afterInvocation` that gets invoked before and after a method is invoked by TestNG, irrespective of whether they pass/fail or gets skipped
* **`IMethodInterceptor`** - on implementing the interface, we can call ***intercept*** to alter the list of test methods that TestNG is about to run
* **`IReporter`** - on implementing the interface, we have method `generateReport` to create custom reports
* **`ISuiteListener`** - on implementing the interface, we can call `onStart` and `onFinish`
* **`ITestListener`** - on implementing the interface, we have methods `onTestStart`, `onTestSuccess`, `onTestFailure`, `onTestSkipped`, `onTestFailedButWithinSuccessPercentage`, `onTestFailedWithTimeout`, `onStart`, `onFinish`


# Declaring listeners

## In testng.xml

```xml
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd">
<suite name="Sample Test Suite" parallel="tests" thread-count="5">
    <listeners>
        <listener class-name="com.example.SampleTestListener" />
    </listeners>
    <test name="Sample Test">
        ...
    </test>
</suite>
```

Listeners can be configured for the entire test suite in ***testng.xml*** like above. Under *\<listeners\>*, multiple *\<listener\>* can be added.

## In TestClass 

```java
@Listeners( { com.example.SampleTestListener.class } )
public class TestClass {
     ....
}
```

Listeners can be configured only for certain test classes like the above code snippet by adding `@Listeners({ ListenerA.class, ListenerB.class, ...})` at the class level.

That is how listeners work with TestNG. In the next lesson, you will study how to restart a failed test.

In this topic, we will see the list of TestNG Listeners.
