ABSTRACT
With the development of network, the Web application development has become one of the mainstream fields in developing software. Substantial business, such as the bank, government, medical, and other industries, are achieved through Web application. Therefore, the Web application’s reliability must be guaranteed, but the report shows the actual quality of the Web application is not satisfied. Thereinafter, it is necessary to research the reliability test of the Web applications. TTCN-3 is a universal black box test language and a technology. There are two benefits to test the reliability of Web applications by using TTCN-3 [1]. First, the TTCN-3 language specification allows testers to design test cases and test data which have more reasonable structure and higher degree of reuse. Reliability test usually needs to write test cases which are large scale and complex structures. TTCN-3 can ensure the quality and reliability of test script as a mature test language and technical specification. Second, TTCN-3 has realized a large number of function test suite, which is convenient to construct the reliable test system rapidly. TTCN-3 reliability test can reuse the TRI of the function test [2].
