Benefits of testing
A structured testing programme turns hunches into proven results. Software testing has, for decades, provided application developers and software designers with the tools and methods necessary to create robust software.

Functional testing is the type most commonly practiced. It takes a functional definition – an object, an action on that object, and the expected result – and allows the tester to determine whether the feature is behaving as it should.
Where functional testing gets more interesting is in testing the extremes. An humorous example is where a fictional software tester goes to the self-checkout in the supermarket, and when asked how many of her own bags she is using, enters “9999999999”. How does the checkout software respond to that input? And how should it?
Functional testing can reveal interesting assumptions about user behaviour, made by the designer/developer. It also allows a systematic way of dismantling assumptions and questioning the nature of the software itself, exemplified in methods such as Test-Driven Development.
Functional testing also benefits from testing tools that can be programmed to perform user actions automatically, paving the way for a combination of functional and performance testing methods.
Testing the performance (the non-functional aspect) of the application is equally important. But performance not only relates to how quickly an action occurs, but also what happens in adverse conditions. How does the application perform without an internet connection?
Software tools can also assist with performance testing. The best-known example is likely to be Google Chrome’s Developer Tools. By combining object inspection with performance analysis, problem areas in software can be identified and resolved more efficiently.
Security testing an application can be conducted in a number of ways. There is no single method that can ever cover the entire range of security risks an application or service can face. Semi-automated tools can assist the tester in speeding up testing, or increasing coverage, but the ability to further investigate and make recommendations comes from knowledge in systems and software development.
Website security testing, including penetration testing, is also an activity that benefits from software development and systems knowledge. Taking industry best-practice tools and methods, website testing is often useful in highlighting security shortcomings that are often easily remedied.
