Towards quality programming in the automated testing of distributed applications
PhD ThesisSoftware testing is a very time-consuming and tedious activity and accounts for over 25% of
the cost of software development. In addition to its high cost, manual testing is unpopular and
often inconsistently executed. Software Testing Environments (STEs) overcome the deficiencies
of manual testing through automating the test process and integrating testing tools to support a
wide range of test capabilities.
Most prior work on testing is in single-thread applications. This thesis is a contribution to testing
of distributed applications, which has not been well explored. To address two crucial issues in
testing, when to stop testing and how good the software is after testing, a statistics-based
integrated test environment which is an extension of the testing concept in Quality Programming
for distributed applications is presented. It provides automatic support for test execution by the
Test Driver, test development by the SMAD Tree Editor and the Test Data Generator, test failure
analysis by the Test Results Validator and the Test Paths Tracer, test measurement by the Quality
Analyst, test management by the Test Manager and test planning by the Modeller. These tools
are integrated around a public, shared data model describing the data entities and relationships
which are manipulable by these tools. It enables early entry of the test process into the life cycle
due to the definition of the quality planning and message-flow routings in the modelling. After
well-prepared modelling and requirements specification are undertaken, the test process and the
software design and implementation can proceed concurrently.
A simple banking application written using Java Remote Method Invocation (RMI) and Java
DataBase Connectivity (JDBC) shows the testing process of fitting it into the integrated test
environment. The concept of the automated test execution through mobile agents across multiple
platforms is also illustrated on this 3-tier client/server application.The National Science Council, Taiwan:
