Behavior-Driven Development (BDD) is an agile software development practice that enhances the paradigm of Test Driven Development (TDD) and acceptance tests. By using OpKey - Web, you can write your Gherkin story, associate with Function Libraries & Data Repositories for data driving and execute Gherkin files individually and by adding to the Test Case.
After creating your Gherkin story(s), you can execute it by using 'Run Now' or 'Debug Now' button. In addition, you can execute multiple Gherkin stories simultaneously by adding them to a Suite.
