𝐏𝐚𝐫𝐚𝐥𝐥𝐞𝐥 𝐄𝐱𝐞𝐜𝐮𝐭𝐢𝐨𝐧: Parallel Execution is used to reduce execution test cases by executing test cases concurrently using Multi threading


Let us understand TestNG at high level first:

𝐓𝐞𝐬𝐭 𝐜𝐚𝐬𝐞 𝐢𝐧 𝐓𝐞𝐬𝐭𝐍𝐆:
-One method having @Test annotation is known as Test case in TestNG

𝐇𝐨𝐰 𝐭𝐨 𝐞𝐱𝐞𝐜𝐮𝐭𝐞 𝐭𝐞𝐬𝐭 𝐜𝐚𝐬𝐞𝐬 𝐮𝐬𝐢𝐧𝐠 𝐓𝐞𝐬𝐭𝐍𝐆:
-We can execute TestNG test cases in multiple ways: individually, using class and using testing.xml



𝐓𝐞𝐬𝐭𝐍𝐆.𝐱𝐦𝐥:
-It is suite file which is used to configure different test classes and TestNG test cases
-here we can provide different parameters and configurations related to parallel execution


𝐏𝐚𝐫𝐚𝐥𝐥𝐞𝐥 𝐄𝐱𝐞𝐜𝐮𝐭𝐢𝐨𝐧 𝐢𝐧 𝐓𝐞𝐬𝐭𝐍𝐆:
-TestNG provides a feature to execute test cases in parallel using TestNG.xml
-In TestNG.xml we can provide parallel attribute at suite level as well as test level to execute test cases in parallely
-Parallel can accept multiple values: none | methods | classes | tests

𝐏𝐚𝐫𝐚𝐥𝐥𝐞𝐥=𝐜𝐥𝐚𝐬𝐬𝐞𝐬 | 𝐦𝐞𝐭𝐡𝐨𝐝𝐬 | 𝐭𝐞𝐬𝐭𝐬 | 𝐧𝐨𝐧𝐞
1. Parallel=none: sequential execution
2. Parallel= classes: each class will get separate threads
3. Parallel= methods: each test method will get separate threads
4. Parallel = tests: each test block in testing.xml will get separate thread.

𝐓𝐡𝐫𝐞𝐚𝐝-𝐜𝐨𝐮𝐧𝐭:
-by default TestNG allows 𝟓 𝐭𝐡𝐫𝐞𝐚𝐝𝐬 to run in parallel but we can override this value by providing thread-count=some integer value

Let us catch up in video
