Triniti Advanced Software Labs, Hyderabad, INDIA July 10 Jan 11

Role: Java Intern

Triniti Testing Tool (TTT)

Triniti Testing Tool facilitates users to automate the testing of java application. It allows GUI testing and regression testing. This tool supports testing at unit level, module level and application level. It creates tests by recording actions performed on the application which is to be tested. Entire business process will be captured in TRi2 and business functionality will be captured in TTT. After applying patch each and every test case generated from scenarios can be tested without human intervention. If test case fails issue will get raised in TRi2 and .hence keeping track of patch, test case and issue.

Responsibilities:

Involved in the integration with Project Management Tool (TRi2). With this integration whole business process can be recorded and can be stored in TRi2 Database. Whenever a patch is released that scenario will be tested without manual intervention.

Involved in development, issue fixing and testing phases.

Developed feature to capture screen shots while recording and replaying. While replaying if at all any error occurs screen shot captured would convey where exactly error occurred and hence user can conclude is it because of functionality error or technical error.

Successful in capturing the error line number and the error script line and displaying the same to user.

For loose coupling between components used Observer design Pattern so that the changes done in one class will be notified to all other classes that are interested to listen.

Used Sockets for Inter Process Communication between two JVM’s. Eliminated JNI’s and DLL’s which earlier was used. Hence making product Platform independent

Implemented Break points feature to stop the replay at a specific line for user convenience.

Implemented check points in the testing tool to check whether the output value is the one expected by the user.

Environment: JDK 1.5, Eclipse, JavaScript, AJAX, Servlets, XML, Tomcat 5.0, DOM, SAX, CVS, Win 2000 Server
