You are here: Home > Bugs and Fixes > What is Testing

Testing is the process of identifying defects, where a defect is any variance between actual and expected results.
What is Testing? _______________________________________
Defect can be caused by a flaw in the application software or by a flaw in the application specification. For example, unexpected (incorrect) results can be from errors made during the construction phase, or from an algorithm incorrectly defined in the specification. Testing is commonly assumed to mean executing software and finding errors. This type of testing is known as dynamic testing, and while valid, it is not the most effective way of testing. Static testing, the review, inspection and validation of development requirements, is the most effective and cost efficient way of testing. A structured approach to testing should use both dynamic and static testing techniques.

Testing and Quality Assurance
What is the relationship between testing and Software Quality Assurance (SQA)? An application that meets its requirements totally can be said to exhibit quality. Quality is not based on a subjective assessment but rather on a clearly demonstrable, and measurable, basis. Quality Assurance and Quality Control are not the same. Quality Control is a process directed at validating that a specific deliverable meets standards, is error free, and is the best deliverable that can be produced. It is a responsibility internal to the team. QA, on the other hand, is a review with a goal of improving the process as well as the deliverable. QA is often an external process. QA is an effective approach to producing a high quality product. One aspect is the process of objectively reviewing project deliverables and the processes that produce them (including testing), to identify defects, and then making recommendations for improvement based on the reviews. The end result is the assurance that the system and application is of high quality, and that the process is working. The achievement of quality goals is well within reach when organizational strategies are used in the testing process. From the client's perspective, an application's quality is high if it meets their expectations.

One of the most important (and most common) things an SQA Engineer does is to write "bug reports". How well you report a bug directly affects how likely the programmer is to fix it. More...
