TestNG – consolidatedchaos

TestNG is testing framework enhancing the Junit framework.

Lets look at different annotations it provides for the test execution stand point.

Following is the list of all annotations that one may require to control after or before facts of test execution. These methods will execute before or after the event is called. These annotations does not depend on the test execution status.

@BeforeSuite
@AfterSuite
@BeforeTest
@AfterTest
@BeforeGroups
@AfterGroups
@BeforeClass
@AfterClass
@BeforeMethod
@AfterMethod

the sample test class with annotations produces following output. All the other annotations does not need any parameters except that before and after group annotation, following is how we can mention the group name.

@BeforeGroups("Sanity")
	public void beforeGroups() {
		System.out.println("Calling before groups");
	}

Output from java console :

Consoleoutput

While doing console logs, I have struggled to get rid off other console messages produced by the chrome driver. Following piece of code is used to suppress the console logs produced by chrome driver, added this just thought might be relevant to share.

System.setProperty("webdriver.chrome.driver", ChromeDriverPath);
System.setProperty("webdriver.chrome.silentOutput", "true");

In TestNG there is provision that we can run tests conditionally, like we can have test case that needed to be executed with flags yes or no and we want to conditionally run these tests.

For this purpose we can make use of ITestAnnotation interface. This provides the interface to override the test annotations during runtime.

TestNG_ItestAnnotation

The above example is listener class that can override the transform method, which dictates the test annotation. We can control the enabled annotation attribute to make test available to pickup by the TestNG framework.

Make sure that you have enabled annotation available for the test. I.E explicitly add this annotation for the test so that, TestNG overrides the Annotation. If this attribute is not there TestNG cannot override the same.
