A tester’s relationship with bugs is similar to that of cops and robbers games. You can catch a hundred, but one going unnoticed straight to release is enough to cause hell to break loose. In other cases, bugs that have been fixed often reappear.
Performing manual testing that covers the largest part of a software application will cost time and money. The more thorough or extensive it becomes, the more the cost rises. However, mistakes are bound to happen. Bugs will always find a way to thrive. Automation is a tool which can increase the effectiveness and efficiency of software testing, in a shorter amount of time.
Cost and time effectiveness
Manual testing is performed by a tester who will scrutinize the software with several different scenarios, to cover the most possible cases that can take place. At the same time, the results must be compared to what is expected, and if a behavior is abnormal or can lead to an unpredictable outcome, it must be recorded and passed to the developers for fixing. To ensure the software’s quality, time is key. Every time a change is made in the software, the process of testing needs to be repeated, which can take a significant amount of time. This is where automation steps in. Running an automated test which will execute the same actions and checks can drastically reduce time that would normally be longer with manual testing, additionally lowering the cost of testing.
Going the extra mile
There is a vast number of cases to be covered in order to thoroughly test software. When time is limited and testing needs to be cut short to fit in it, not every single scenario can be covered manually. In other occasions, a tester must test many roles at once, sometimes having them interact with each other simultaneously. High complexity testing requires time, proper orchestration and adept maneuvering to accomplish the desired outcome. Furthermore, manually repeating a routine eventually becomes dull, and makes a human tester more prone to making mistakes. And while someone might be very proficient at testing, there is a great number of external factors in people’s lives that can affect the quality of one’s work. All the above and even more can be performed effortlessly with automated tests, while keeping the quality standards high. What’s more, it is wise to automate standard procedures that are being tested repeatedly, in order to make the best of the limited time.
There is a number of things that can bring joy to an IT department. Coffee is definitely number 1. Going further, everyone feels accomplished when they see their hard work pay off in the form of properly functioning software products. It begins from the lowest ranks and climbs up higher in hierarchy, but the root cause of joy is the same, and it is the positive results. How can such a thing be accomplished? If everyone does their job well. From QA’s perspective, since they are the last step before something is approved to be released, they are responsible for any mishaps that may escape their attention. So automation can be a tester’s best friend to prevent silly bugs arising. Writing automated tests itself will improve a tester’s morale, because it is something new, something creative, a tool to build a whole web of robust and complex tests and later on improve them. The confidence boost will directly enhance a tester’s automated and manual testing performance. In forms of unit tests, developers also benefit from automation by tracking bugs faster, saving development and testing time, while improving their code. The rising of a team’s spirit will positively affect their surrounding colleagues, and ultimately the organization.
