As IT projects become more complex and existing software continues to evolve, the need for testers to be involved throughout the development process becomes more and more necessary. Wolf have looked at some of the challenges that software testers currently face.
Identifying and Amending Defects
Software testing is based on observations. Even for the most experienced software testers recognising important defects and addressing them at the correct stage can prove challenging. Sometimes described as the ‘Illusion of software testing,’ testers can easily be misled leading to errors made during the process so that programs with defects make it through the testing cycle. This becomes problematic when significant defects make it through to the final product, identifiable to the end user.
A product or service will pass through many stages of functionality testing before being approved. Unit testing, integration testing, system testing and acceptance testing are all stages at which software defects can be missed and end up being incorporated into the final product.
Agile development and Agile Testing
Another challenge faced by developers is the move to agile testing, in line with the rise in agile software development, with code continually being rewritten and added. As a result of frequent builds, code can become fragmented meaning that testing teams must run frequent series of tests on the same code after each agile development sprint. As mistakes are much more difficult to identify and correct when the application becomes more complex, in some cases much of the basic testing needs to be automated.
Complete testing of a product
Complete testing of a product can be a long and almost impossible task because of the huge number of possible test scenarios that can be executed. Fully testing any software would involve testing every way in which the user could potentially use the program, as well as testing every possible combination of inputs and every hardware/software configuration; including that of servers that are not under the control of the tester. This means that there is always potential for bugs to pass through all of the stages of testing into the final program.
