"Exhaustive testing is a test approach in which all possible data combinations are used testing. Exploratory testing includes implicit data combinations present in the state of the software/ data at the start of testing."
It is a very long and tedious method of testing. In this method all the types of inputs are given to the software to check the outputs. Through this method of testing every code is verified. The test may be exhausting but it is the most practical and reliable method. This way software's endurance is verified as well as the ability of the software to work in extreme conditions.
Exhaustive testing is only implacable for small projects. In the complex projects this method would be a disaster as it requires a lot of time and cost. Hence, this method is not reliable for large projects. Exhaustive testing is the process of testing for absolutely everything just to make sure that the product can't be destroyed or crashed by some random happenings. Once, software passes the test it is the most perfect and robust for its application.
It exposes the bugs so that it can be fixed later. The testers apply every permutations and combinations to determine the defects or bugs in a software application. It is said that exhaustive testing is impossible due to its heavy investment in time and money. Other testing is practically easy and possible and it can be applied in all types of project. The sooner the work gets completed, highly productive is the software considered. One can't predict that particular software will run the way it is expected on every situation. It is close to impossible to jot down every aspect that software can go through in the future. The advancement in the technology has made it more difficult.
However, it is difficult to evaluate-
Though, exhaustive testing is impossible, there are few things that can be taken care of while evaluation.
Tips that may be useful while exhaustive testing-
This is all about exhaustive testing which is regarded as pointless and impossible. There are disadvantages and advantages of every single thing that exists. Exhaustive testing has fewer but essential perks that can be applied on small projects to yield better software.
