Interaction Based Software Testing

Abstract

Testing is defined as a process of executing a program or system with the intent of finding errors. Testing consists of validating and verifying the software artifacts so that they meet their business and technical requirements. It is a very important and timeconsuming part of software development life cycle. But most of the software fails because of not being tested properly. The reason behind failure mainly includes errors present in analysis and design phase. In proposed work, design diagrams of the software are used for test cases generation. The test case generation using design helps to plan test case early. Generating test cases from design are more effective and efficient as design is closer to White Box testing. Sometimes during test cases generation, we come to know about any incompleteness and inconsistence in requirement, which can overcome by taking necessary measures taken in time. The proposed system focus on three UML diagrams that are Class, Statechart and Activity diagram. The petal files also called mdl file of these diagrams are parsed by the tool.. It tokenizes the line into words and then matches the string with the pattern to find the test case information. Then the text files created are entered to the Oracle database using SQL *Loader. Before loading text files to SQL *Loader it was necessary to create control file and a Dat file. The control file tells SQL*Loader where to find the data, how to parse and interpret the data and where to insert the data. Dat file which contains the data i.e. the text file from the tool is saved with extension .dat and it serves the purpose of Dat file in SQL *Loader to load the data. The text files in the form of Dat file are loaded to Oracle database. Further queries are fired from Java to extract the strings from database and use them to generate automatic test cases.
