TestNG supports a lot of assertions. It has the org.testng.Assert class, which extends the Java object class java.lang.object.To compare two lists specifically, TestNG's Assert class has a method known as assertEquals(Object actual, Object expected) and there is an extended version of this method with customized message as assertEquals(Object actual, Object expected, String message).This method returns True if −both the objects are Lists, both the lists are of same size, andif the elements of the lists are in the same order.If any of these conditions are not True, it will return False.In this article, we will discuss how to compare two ...

TestNG supports multiple ways to ignore all @Test execution. If required, a user can ignore a complete test without executing it at all. TestNG supports ignoring all @Test at the following levels −In a classIn a particular packageIn a package and all of its child packageThe user has to use @Ignore annotation at the required level to disable the tests. The @Ignore annotation takes higher priority than individual @Test annotation.To disable all the @Test in a class, just type @Ignore before the class name. It will disable all the @Test present inside the class.In this article, we will illustrate how ... Read More

A TestNG class can have various TestNG methods such as @BeforeTest, @AfterTest, @BeforeSuite, @BeforeClass, @BeforeMethod, @test, etc. As per the execution order, @BeforeTest executes first and after that @BeforeClass does. However, if there are multiple TestNG classes and multiple Tests inside each class, the behaviour of these methods is noticeable.@BeforeTestThis method will execute only once in the entire execution before calling the 1st @Test method. It doesn't matter how many @Test tags are present or how many classes are there having @Test tags, or multiple classes have multiple test tags. Based on the testNG.xml file, once the execution starts, the ... Read More

A TestNG class can have various TestNG methods such as −@BeforeTest@AfterTest@BeforeSuite@BeforeClass@BeforeMethod@test, etc.In this article, we will take a look at the order of execution of different TestNG methods.TestNG provides the following methods to support the main @Test method. The order of execution should be as following − Key points in this order are −First of all, beforeSuite() method is executed only once.The afterSuite() method executes only once.Even the methods beforeTest(), beforeClass(), afterClass(), and afterTest() methods are executed only once.beforeMethod() executes for each test case (every time for a new @Test) but before executing ...

A TestNG class can have different tests like test1, test2, test3, etc. Once a user runs the TestNG class consisting of various tests, it runs the test cases in an alphabetic order based on the names provided. However, the user can assign the priority to these tests so that these tests can run as per user's priority. Priority starts from "0" which takes the highest priority and as the number moves up, the priority decreases.In this article, let's analyse how the order of execution with priority works in TestNG.Scenario 1If test2 (priority=0), test1 (priority=1), test3 (priority=2), then test2 will run ...

testng.xml has a format as where we define all the test classes that should be executed. There are no specific ways to exclude a class in , but there are workarounds that are quite useful in case you don't want to run a specific class in a testing suite.Following are some of the handy ways to exclude a test class run from a test suite.As usual, just mention the class names those are required to execute and remove the class names that are not supposed to execute.Mention all the class names inside including the ones that should not ...

TestNG supports multiple ways to skip or ignore a @Test execution. Based on requirement, the user can skip a complete test without executing it at all or skip a test based on a specific condition. If the condition meets at the time of execution, it skips the remaining code in the test.Following are the ways to skip the @Test execution −Use the parameter enabled=false at @Test. By default, this parameter is set to True.Use throw new SkipException(String message) to skip a test.Conditional Skip − The user can have a condition check. If the condition is met, it will throw a ... Read More

Group test is a new innovative feature in TestNG, which is not available in JUnit framework. It permits you to dispatch methods into proper portions and perform sophisticated groupings of test methods.Not only can you declare those methods that belong to groups, but you can also specify groups that contain other groups. Then, TestNG can be invoked and asked to include a certain set of groups (or regular expressions), while excluding other sets.Group tests provide maximum flexibility in how you partition your tests. You do not have to recompile anything if you want to run two different sets of tests ... Read More

TestNG supports native dependency injection. It allows to declare additional parameters in methods. At the runtime, TestNG automatically fills these parameters with the right value.Here is a list of some of the native dependencies in TestNG −ITestContextXmlTestMethodITestResultThese dependencies help to retrieve the test suite name depending on where these are called. If the user wants to retrieve the test suite name before execution or after execution, the best place is @BeforeSuite or @AfterSuite.@BeforeSuite and @AfterSuite support ITestContext. However, the full access of these dependencies is given in the following table −AnnotationITestContextXmlTestMethodITestResultBeforeSuiteYesNoNoNoBeforeTestYesYesNoNoBeforeGroupsYesYesNoNoBeforeClassYesYesNoNoBeforeMethodYesYesYesYesTestYesNoNoNoAfterMethodYesYesYesYesAfterClassYesYesNoNoAfterGroupsYesYesNoNoAfterTestYesYesNoNoAfterSuiteYesNoNoNoIn this article, we will use ITestContext dependency to show ...
