On the completion of the development of software, it is essential that the team runs a testing life cycle to ensure that the programs are all free of bugs and that there is no loop holes left in it. This helps in eradicating problems that might arise in future if the problems are not rectified before the software is finally implemented.
The testing life cycle starts with creating a test plan where the programmer designs the testing process for the developed software. This usually involves the creation of a flowchart diagram that facilitates with step by step instructions to follow.
Once the plan is in place, the product is finally put to test. Every program of the software is tested for correct logical execution and intended output. This process helps in identifying the bugs present in the system. These bugs are very often logical errors and systematic loop holes that need to be modified for the program to run smoothly.
The bugs are then reported to the developer who starts the rectification process. Once the developer is satisfied, the software is forwarded to the Quality Assurance department to run a comprehensive test on it. Upon successful completion of the test, a verification report is published which states that the software has been cleared of all possible bugs and loop holes. In case of failure, a report is sent back to the developer stating the problems found and possible rectification measures.
Once the software is completely debugged and verified, it is passed fit for implementation. The bugs that were found out are reported for future references and avoidance of repetition in future projects. This makes the final step of the testing life cycle.
The implementation process involves either parallel installation where the old and the new system is used simultaneously until the staff gets acquainted with the new features or it can be an instant implementation where the old system is completely eliminated. This decision is upon the discretion of the client.
The testing life cycle is vital as it saves you a lot of trouble shooting costs and also ensures that your client remains satisfied with your softwareâ€™s performance.
