How mature is your Software Testing? All software products are tested continuously through all stages, right from idea conception to release. The maturity index of a product is a function of the degree of readiness demonstrated by it for release. Process maturity of the test suite is core to release highly functional products that match and exceed client expectations. The CMM (Capability Maturity Model) is a testing model developed in the 1980s by the SEI (Software Testing Institute) that outlines a framework for effective processes in software development. What is a mature test? A mature test is less on abstraction and more on agility. It can be left unmanned without any need for intervention to check its correctness and continuity. When the testing process is mature, more emphasis is laid on defect prevention instead of defect detection. Testing maturity is a staged architecture and cannot be achieved overnight. Every organization differs from others in the maturity levels of its testing processes.
A process improvement approach Many organization use the concept of maturity as a structured tool to assess where they stand with regards to adequateness of their testing suite for dynamic environments in which software products are developed. By optimizing the processes and behaviours in the testing process, the goal of the maturity concept is to ensure that the testing process becomes a continuous improvement practise and not a stand-alone exercise.
Towards a Testing Maturity Model The five levels of maturity for testing processes outlined by the CMM model include Initial, Repeatable, Defined, Managed and Optimizing. The levels start on an ascending continuum, with level 1 indicating an infancy level, leading to a completely mature testing model in level 5. Whereas in the initial stage, you cannot afford to leave the tests unattended even for a few hours, at level 5, the testing suite is completely automated and mature. Similar to the CMM model, the Testing Maturity Model (TMM) also represents a staged approach, namely Initialization, Definition, Integration, Management & Measurement and Optimization. An optimized tester demonstrates highest levels of test maturity.
The testing process is highly quality oriented and must be manned by well-qualified personnel to reap the best results. It must adhere to professional standards in debugging and fault-finding. a mature test is one that self-integrates itself to the software development lifecycle. As an improvement to the 5 stage CMM model, the Beizer’s Progressive Phases of Tester’s Mental Model is built around the thought processes of testers. The success of a mature test cannot be fully confined to the feature of automation. A hundred percent error-free test completion report alone does not suffice, to rank your testing process
as mature. On a broader spectrum, mature â€‹software testinâ€‹g is all about end-to-end management of the testing process by professionals with a planned approach and precision in decision making and implementation.
