![]() ![]() Step 4 − Repeat the steps for test2 and test3. Step 2 − Write an annotation as 3 − Repeat the steps for test2 and test3. Since all tests are having same priority, it executes in an alphabetic order. By default, TestNG assigns priority as 0 to all tests if priority is not defined by the user. By default, test1 will run first and after that test2 and finally test3. TestNG executes different tests alphabetically. Priority starts from 0 (highest priority) and gradually decreases as we move to 1, 2, 3, etc. However, the user can assign the priority to these tests so that these tests can run as per user's priority. Once a user runs a TestNG class consisting of various tests, it runs the test cases in an alphabetic order based on the name provided. However, newer versions of the test framework allow you to annotate your test classes using which enables you to select one of various MethodSorters.A TestNG class can have different tests like test1, test2, test3, etc. In the remainder of this post, we’re going to have a look at how you can define test execution order in JUnit, TestNG and NUnit.īefore version 4.11, JUnit did not support controlling the test execution order. ![]() Luckily, most testing frameworks support this in one or more ways. The above situation is just one example of a case where being able to control the execution order of your tests can come in very useful. Using Background is not an option, because those steps are run before each individual scenario, whereas we want to run the test data creation steps once every feature. This means that the test data creation scenario needs to be run first, otherwise the subsequent scenarios will fail. All other scenarios in the feature rely on this test data. Since we’re using SpecFlow, we’re creating test data in the first scenario in every feature. Creating the necessary test data before each and every individual test would just take too long. The only viable option is to make the creation of test data the first step in a test run. ![]() This has to be done through the user interface since a lot of data is stored in blobs, making SQL updates a challenging strategy to say the least. Creation of suitable test data takes at least a minute but closer to two for most tests.Restoring a database snapshot is not a feasible option (at least not at the moment).I don’t want to rely on test data that’s already being present in the database.For example, in my current project I am automating of a number of regression tests that require specific test data to be present before the actual checks can be performed. However, in some cases, having your tests run in a specific order can be the most pragmatic or even the only (practical) option. Especially when you’re talking about end-to-end user interface tests that only run overnight because they’re taking so awfully long to finish. ![]() Nothing worse than a complete test run being wasted because some initial test data setup actions failed, causing all other tests to fail as well. This is generally a good practice and one I try and adhere to as much as possible. That is, tests should be runnable in any given order and the result of a test should not depend on the outcome of one or more previous tests. General consensus within the test automation community is that your automated tests should be able to run independently. ![]()
