Parallel testing is a process of running the test cases or modules simultaneously rather than consecutively on different threads. The TestNG framework allows us to execute multiple test cases parallel over different environments instead of running test cases one after another. It helps to reduce the testing time and effort.<\/p>\n

TestNG provides different ways to execute tests in separate threads by using the parallel attribute in the testng.xml file. Where we can set the parallel attribute to method, tests, and classes.
\n<suite name=\"Suite\" parallel = \"methods\">...<\/suite><\/code>
\nHere, all the methods with Test annotation will execute parallel.<\/p>\n

The parallel test attribute can accept only four values:<\/h2>\n
    \n
  1. Tests <\/em>\u2013 All the tests inside the test tag will run parallel.<\/li>\n
  2. Classes <\/em>\u2013 All the tests inside a java class will run parallel.<\/li>\n
  3. Methods <\/em>\u2013 All the methods with test annotation will execute parallel.<\/li>\n
  4. Instances <\/em>\u2013 Tests in the same instance will execute parallel.<\/li>\n<\/ol>\n

    Example:<\/strong> Here is an example of a webner solutions website<\/a> that will execute on different browsers simultaneously and check the loading time.<\/p>\n
