Increase Test Efficiency with DataProviders in TestNG | TO THE NEW Blog
Summary
There are several scenarios when we need to run a single test case multiple times on more than one valid/invalid input. Let us understand this with an example: TestCase: Verify if the user can sign up or not Let’s say, there is a website whose Signup page only accepts Business Emails [not Gmail, Yahoo, etc.]. If a user tries to register with his/her Business Email, then the test case passes, while if the user tries to register using a Gmail or Yahoo account, he/she gets an error “Only Business Email allowed” on screen. If you’re using Maven, add TestNG to your pom.xml file: You can get it on this Link The second step is to create a method with @DataProvider annotation that returns a two-dimensional object array. Data Providers in TestNG are a powerful tool for running parameterized tests efficiently.
