Product based company develops the applications for Global clients i.e. there is no specific clients. Here requirements are gathered from market and analyzed with experts.
Project based company develops the applications for the specific client. The requirements are gathered from the client and analyzed with the client.
TRM means Test Responsibility Matrix.
TRM: --- It indicates mapping between test factors and development stages...
Test factors like:
Ease of use, reliability, portability, authorization, access control, audit trail, ease of operates, maintainable... Like dat...
Requirement gathering, Analysis, design, coding, testing, and maintenance
Traceability matrix is prepared in order to cross check the test cases designed against each requirement, hence giving an opportunity to verify that all the requirements are covered in testing the application.
To Cross verify the prepared test cases and test scripts with user requirements. To monitor the changes, enhance occurred during the development of the project.
It is the probability that software will work without failure for a specified period of time in a specified environment.Reliability of software is measured in terms of Mean Time Between Failure (MTBF). For eg if MTBF = 10000 hours for an average software, then it should not fail for 10000 hours of continous operation.
Measurement is fundamental to any engineering discipline
- We cannot control what we cannot measure!
- Metrics helps to measure quality
- Serves as dash-board
The main metrices are :size,shedule,defects.In this there are main sub metrices.
Test Coverage = Number of units (KLOC/FP) tested / total size of the system
Test cost (in %) = Cost of testing / total cost *100
Cost to locate defect = Cost of testing / the number of defects located
Defects detected in testing (in %) = Defects detected in testing / total system defects*100
Acceptance criteria tested = Acceptance criteria tested / total acceptance criteria
