There is an age-old expression that says “You only have one chance to make a first impression.” This is a hard truth in today’s world of instant gratification. If your product fails to deliver the first time, your customers will simply move on to the next thing. In-the-wild functional testing, as provided at uTest, is similar to a dress rehearsal for your application. Your application is exposed to a group of people who accurately represent your potential user base. They can identify and report the issues (that would have negatively impacted your customer’s first impression) before your customer ever has the chance to see them.
A functional tester has the ability to evaluate individual features of an application. They are familiar with typical application behavior and have the skills needed to look objectively at a feature and see what’s wrong.
Perhaps even more valuable is a functional tester who is able to analyze individual pieces of an application within the context of the entire application. A functional tester looks at a particular item, identifies integration points between that item and other parts of the application, and then formulates a plan of how to inspect those touch points. Applications are usually weakest in places where different parts come together. A strong functional tester knows this and knows how to exploit those weaknesses to identify any lurking bugs.
Functional testing will only be successful if an organization’s underlying quality fundamentals are solid and everyone clearly understands how testing helps achieve the goals of the business. Functional testing is only one of many activities that collectively comprise a comprehensive testing strategy. Depending on the needs and expectations of your company, different testing activities such as performance, load, and security testing should be considered. Functional testing differs from other types of testing in that it most closely reflects the experience of the users. While performance affects the experience and security issues add risk to the experience – how the application functions IS the experience.
