Manual and automation testing. What are the differences? When do you have to choose manual testing and when- automation testing? Advantages and disadvantages by both directions of the quality assurance process … Learn more in our article below.
Quality Assurance is the thorough process of monitoring, analyzing, and optimizing both the production process and the final product itself so that all potential problems and defects can be eliminated.
Along with Quality Control, Quality Assurance services are an essential success factor in various niches – from software development to manufacturing all types of products and goods.
Basically, there are two main ways to conduct quality assurance: manually or by automation testing. What does each mean, what are the pros and cons, and how to choose your approach? Here are some simple answers to the complicated questions you might be asking yourself.
Quality Assurance: Manual Testing
Manual testing is a type of quality assurance method where a quality assurance specialist – a human being – checks all the essential characteristics of the given product or application.
It is a standard and long-practiced type of service that has both its pros and its cons. Despite the more moderate initial investment and the swift visual feedback, manual testing often leaves space for human errors, has a comparatively lower ROI, and takes a lot more time than automation testing.
Practice shows that manual testing is primarily suitable for usability, exploratory, and ad-hoc testing, where the object needs to be tested no more than one or two times before launching.
Quality Assurance: Automation Testing
Automation testing is indeed a game-changer here, as it operates steadily, repeatedly, speedily, and reliably, without the ups and downs inherent to a human being.
It runs on specially written scripts made to compare actual with expected results. As an outcome, the testing takes a minimum amount of time and ensures a greater ROI, despite the higher initial investment in tools and software.
Automation testing excludes the chances of human error and considerably augments productivity. It also allows for greater transparency of the process, as every step of it is recorded and can be audited in real-time or post-factum.
Automation testing is proven to be perfect for highly repeatable functional test cases, such as load testing, performance testing, regression testing, etc.
