TESTNG ANNOTATIONS MANUAL

If not, then AssertionError is thrown.ĪssertEquals(Collection actual, Collection expected, String message) Īsserts that two Collection type objects hold the same elements and in the same order.

Message: message that we want to display in case of failureĪssertEquals(boolean actual, boolean expected, String message) Īsserts that two boolean values are equal. In this section, we will see the most commonly used assertion methods available for TestNG assertionsĪssertEquals(String actual, String expected, String message) Īsserts that two strings are equal. TestNG provides different methods to validate the test result during script execution.

Shown below is the generic syntax of TestNG assertions: The Assert package in TestNG provides methods(or options) to raise assertions. Let’s look at the syntax and other internals of assertions in TestNG. The above example that demonstrated TestNG assertions gives an overall idea about the what & how of assertions. Test case result: Failed, as fetched title does not match with the expected title.Expected Title: Most Powerful Cross Browser Testing Tool Online.Test case result: Passed, as fetched title matches the expected title.Expected Title: Most Powerful Cross Browser Testing Tool Online | LambdaTest.Fetched Title: Most Powerful Cross Browser Testing Tool Online | LambdaTest.Here expected result would be ‘Most Powerful Cross Browser Testing Tool Online | LambdaTest.’ The following cases can arise during the process of test execution: Let’s take a simple test scenario where the page title of the LambdaTest homepage has to be validated before further tests can be executed. For using TestNG assertions, all you need to do is import the package. TestNG assertion is raised if the ‘achieved test result’ is not the same as the ‘expected test result.’Īssert Class in TestNG provides different methods that can be used to raise asserts. The outcome of the test can be decided based on the assertion status. Hence, the generic concept of Asserts and Verify in Selenium is synonymous across different automation frameworks.Īs far as the TestNG framework is concerned, asserts in TestNG are used for validating the scenario under test. In this Selenium TestNG tutorial, we look at what are assertions in TestNG, different types of TestNG assertions, and how they can be used in scenarios pertaining to Selenium automation testing.Įvery test automation framework (e.g., TestNG, JUnit, PyTest, etc.) provides a mechanism to raise asserts. Thus, when performing Selenium automation testing with TestNG, assertions can be used for taking relevant steps when an issue is encountered. The test execution halts when the condition (part of the assert) is not met. This is where Asserts in Selenium WebDriver comes to the rescue.

If the issue encountered is a minor one, we can still proceed with the execution otherwise, it is recommended to halt the test execution. This is especially important in cases where the result of the previous test execution has resulted in a failure. When doing Selenium automation testing, we might come across a number of scenarios where a decision needs to be made on the subsequent execution of the tests. Irrespective of the type of testing approach being used, it is necessary to know the point at which the tests have to be halted (or stopped).
