The popular Agile development pattern sets off an upsurge of automatic testing. It makes the cooperation of development and testing become more and more closely. This paper creates an automated testing frameset that can combine BDD agile development concept and software testing together. First we use Gherkin language to define acceptance criteria, which helps the business personnel, testing engineer and development engineer to form a clear and unified understanding of the system requirement. Then we use the web driver testing codes to realize the specific acceptance test, and write the product codes based on TDD. The frameset adopts the Specflow, Selenium and MsTest testing tools. It truly realizes the automated testing, and greatly reduces the manual test pressure. Meanwhile it facilitates the communication of software development stakeholders during development and testing process, gets the feedback from users in time, meets the needs of the rapid release of the product, and also improve the quality of the product.
