TestNG Tutorial #7 running tests parallel in TestNg using XML file

What Is TestNG.Xml?

TestNG.xml file is a configuration file that helps in organizing our tests. It allows testers to create and handle multiple test classes, define test suites and tests.

It makes a tester’s job easier by controlling the execution of tests by putting all the test cases together and run it under one XML file.

Major advantages of TestNG.xml file are:

• It provides parallel execution of test methods.
• It allows the dependency of one test method on another test method.
• It helps in prioritizing our test methods.
• It allows grouping of test methods into test groups.
• It supports the parameterization of test cases using @Parameters annotation.
• It helps in Data-driven testing using @DataProvider annotation.
• It has different types of assertions that help in validating the expected results with the actual results.
• It has different types of HTML reports, Extent reports, etc. for a better and clear understanding of our test summary.
• It has listeners who help in creating logs.
