A call trace based technique for regression test selection of enterprise web applications (SoRTEA)

Regression testing is applied to a modified program to ensure no new errors are introduced in previously tested code. This testing is computationally intensive and time consuming. Hence, Regression Test Selection (RTS) techniques are used to select necessary test cases for testing the modified program. The test cases selected from the test suite should potentially identify same errors as identified by running the complete test suite. The existing RTS techniques address only the web services and standalone applications. In this paper, we present a technique to select regression test cases for web based Java applications. Majority of the web applications follow Service Oriented Architecture (SOA). The server side components are often distributed and work independently on different nodes. Testing these components is difficult and time consuming. The distributed and batch nature of application leads to major challenges in testing them effectively. We list out some of these challenges and present our tool SoRTEA (Selection of Regression Test for Enterprise Application), which addresses few of them in selection of the regression test cases.
