System Testing

Our main purpose of testing work is to find the issues which exist in the application or product, to make it more feasible and try to help provide the reasonable improvement method.
• Prepare test plan according to the application. A test plan documents the strategy that will be used to verify and ensure that a hardware product or system meets its design specifications and other requirements.
• Be familiar with functional specification and new requirements, prepare test case according to functionality. We try to cover all the test points existing in the functional specification. In order to fully test that all the requirements of an application are met, there must be at least one test case for each requirement unless a requirement has sub-requirements. In that situation, each sub-requirement must have at least one test case. We create at least two test cases for each requirement. One of them is performing positive testing of requirement and other is performing negative testing. Written test cases include a description of the functionality to be tested, and the preparation required to ensure that the test can be conducted.
• After coding for any function, we need to do Unit Test. It contains functional testing and source testing. Functionality testing is test the functionality and stability manually and records the defects which weer found during the testing and provides a defect reports for developers. In source testing, unit testing is a method of testing that verifies the individual units of source code are working properly. A unit is the smallest testable part of an application. In procedural programming a unit may be an individual program, function, procedure, etc.
• Integration testing. Integration testing takes as its input modules that have been unit tested, groups them in larger aggregates, applies tests defined in an integration test plan to those aggregates, and delivers as its output the integrated system ready for system testing. Test cases are constructed to test that all components within assemblages interact correctly.
• Make auto test scripts by QTP or Rational test tools and then test by automation. These tools available help the testers in the automation of the GUI which reduce the test time as well as the cost, using the comparison of actual outcomes to predicted outcomes, the setting up of test preconditions, and other test control and test reporting functions to find the defects.
• Using LoadRunner to do the Performance Testing with specified concurrent users for the given application or product, produces the test report and also provides the improved suggestions after analyzing the report.
