A software tester evaluates software based on certain parameters. These parameters are set as per product, customer and organization requirements. Testing could be just of functional features or include load, performance and security. For any parameters a tester has to work as quality analyst to understand requirements, features and accordingly build test cases and perform test. This is the quality control part. On quality assurance front the quality team has to build standards for requirement freezing, planning, development, implementation and post implementation phases of a project.

A software tester at various stages of a project gets on to the job of a Quality Analyst by performing following tasks:

Analysis of customer requirements: The first and foremost analysis required is that of the customer requirements to ascertain if it is complete, detailed and free from any confusions, ambiguities or equivocalness. Any flaw in requirements will certainly lead to a big disaster at a later stage. Unclear requirements are not difficult to build, but are difficult to manage. Every requirement should be in black and white. Each line should be very clearly documented such there should be nothing hidden between the lines.

Analysis of Product Functionality: Requirements documented and product built has to go hand in hand. It should not happen that requirements and product speak differently even a single line. Usually while testing functionality of a product, tester forgets to refer to requirements documented, or asks developer about the functionality. The developer will certainly explain him the functionality he has built not what exactly has been mentioned in the requirements document. If this happens, it will certainly cause a big blast at implementation or acceptance stage.

Analysis of Product related documents: There are many documents prepared during the project. Some are meant for internal use, some are prepared for customer. All these documents need to be inspected thoroughly and neatly.

Analysis of test results: Test cases are built to perform tests resulting in bugs report or test results report. A thorough scan is must to ensure complete coverage and thorough testing. The report should be detailed in all respects in terms of clarity and coverage.

Analysis of Testing Process: The testing process once establishes need to be revisited again and again to improve further at every go. Once established does not mean it is ultimate and best. Improvement has always a scope howsoever best your process or product is.

Why software testing effort estimation is important after functional specifications finalization phase?

If we go by quality standards the sizing of software testing effort has to be done before the tester(s) start writing the test cases for the purpose. The estimate will clearly draw out of the functional specifications signed off between the customer and vendor. Without sizing the Testing manager can never create a testing plan based on which he will decide the number of days and persons required to write test cases, perform testing, draw out the testing results, submit the result report to development team and get the reported bugs resolved. The plan will comprise of time-line and no. of persons required for each of this phase in the sequence mentioned above.

To calculate a reasonable testing time-line estimate based on functional specifications there are certain guidelines that need to be followed: the person who is planning has to have ample business and testing knowledge. Unless (s)he has the right business knowledge (s)he will not be able to select the right persons for writing test cases, or able to guide them on the critical business rules and processes written in the software to hit upon. In that case the best of the test cases will lack the complete coverage and accuracy in testing. The software may lack bug-proofing at the end and customer will be the sole sufferer. Ultimately it is going to effect the software, and the organization that built it.
