testng.xml has a format as where we define what all test classes should be executed. There is no any specific way to provide regular expression in a class in . But there are work arounds those are useful to run specific @Test from a class. TestNG supports regular expression at include, exclude and package tags. Here, the problem statement is when a user wants to run only specific classes those are having specific format like initial name of classes should be same. For example, the user wants to run all classes whose name starts with NewTest. In this ... Read More

TestNG is a powerful testing framework, an enhanced version of JUnit which was in use for a long time before TestNG came into existence. NG stands for 'Next Generation'. TestNG framework provides the following features − Annotations help us organize the tests easily. Flexible test configuration. Multiple test cases can be grouped more easily. Parallelization of tests can be achieved using TestNG. Support for data− driven testing. Inbuilt reporting as well as supported by Extent Reporting and other reporting tools. Selenium by default doesn’t generate any report. Easily configured for Cross Browser testing. TestNG framework can easily integrate ... Read More

TestNG supports multiple exceptions in single @Test method. It is similar to the catch exception in Java where user can mention multiple exception class those are possible to be thrown. Ex: Syntax in catch exception is: catch(IOException | InterruptedException ex) { Similarly, syntax in TestNG is: @Test(expectedExceptions={NullPointerException.class, IllegalArgumentException.class }) public void throwsNullPointer() { throw new NullPointerException(); } One point to note that, in such scenarios, TestNG expects the one of the exceptions must be thrown from the list. If exception is different from the list or no exception, in such cases it fails the method. ... Read More

If condition meets at the time of execution, it skips remaining code in the test. There are following ways to skip the @Test execution Use the parameter enabled=false at @Test. By default, this parameter is set as true. Use throw new SkipException(String message) to skip a test. Conditional Skip − User can have a condition check, if condition is met, it will throw SkipException and ... Read More

User may encounter Cannot find class in classpath exception while executing tests in TestNG framework. The meaning of this error is TestNG unable to find the class as mentioned in testng.xml. This can be caused because of the following reasons − In the TestNG XML, the class tag having the name attribute. User should define the class name as . format. It should not have the .java extension. In the TestNG XML, the class file is incorrect and hence unable to determine the classpath of the class. Errors within the project are present and may require a clean project. ... Read More

Data types can be used to assert are String, int, Boolean etc. The user should make sure both of values are same data type otherwise it will throw the exception. Syntax is: assertEquals(actual, expected) It accepts 2 parameters − actual and expected to assert values. When given 2 data are same, assertion gets passed without any exception. However, if both of data are no same it throws ... Read More

TestNG Listeners have the capacity to listen to a specific incident. It is basically an interface that changes the nature of the system. TestNG Listeners are used for logging purposes and creating reports. TestNG can be configured with the Listeners which can change the default behavior of the TestNG. There are several interfaces that allows to modify TestNG's behavior. These interfaces are broadly called "TestNG Listeners". Here are a few listeners: IAnnotationTransformer IAnnotationTransformer2 IHookable IInvokedMethodListener IMethodInterceptor IReporter generateReport(java.util.List xmlSuites, java.util.List suites, java.lang.String outputDirectory) - Generate a report for the given ...
