Abstract: For the growing demands of Web application functional testing and test reuse, a TTCN-3 based Web application functional testing method was proposed. The method combined hierarchical thinking with TTCN-3 features, and divided Web application functional testing into three levels: page testing, and session testing, scenario testing. The TTCN-3 test processes were given respectively from three levels of Web application. This method used parametric designing idea of TTCN-3 test cases, effectively separated test design and test implementation, so that test cases would be highly reusable. Examples illustrate that the method is effective.

摘要： 针对日益增长的Web应用功能测试需求与测试重用需求，提出了一种基于TTCN-3的Web应用功能测试方法。该方法结合分层测试的思想以及TTCN-3的特点，提出将Web应用功能测试划分为页面内容测试、会话管理测试、使用场景测试等3个层次，并分别从这3个层次给出了采用TTCN-3进行测试的过程。该方法应用TTCN-3参数化设计测试用例的思想，有效分离了测试设计与测试实现，使测试用例具有高可重用性。结合实例，表明了该方法的有效性。
