Concept of Exhaustive Testing 

Comprehensive testing, also referred to as exhaustive testing, is a testing strategy that seeks to test every possible data combination and leave no room for more testing. In other words, all testing parameters have been thoroughly examined after extensive testing. Quality Assurance includes exhaustive testing, which guarantees that under no circumstances will the application cause a system crash or other malfunction.  

In this blog post, we’ll discuss how exhaustive testing is different from extensive testing. Additionally, we’ll explore several crucial aspects of exhaustive testing and comprehend how it’s carried out. 

Let’s Begin! 

Difference b/w Exhaustive Testing and Extensive Testing 

Parameters	Exhaustive Testing	Extensive Testing
Definition	It tests the application for every conceivable input parameter.	It tests the application’s performance and evaluates specific features with respect to available resources.
Feasibility	Practically speaking, it’s impossible.	The system can be put to the test.
Duration	It takes a long time for the testing team and is quite exhaustive.	For the testing team, it doesn’t take long and is quite simple.
Approach	It is primarily a theoretical approach with documentation.	It is an entirely practical approach, in which the testing team evaluates the system’s effectiveness.
Cost	Because every test case is checked in depth, the process is expensive.	Because of its affordability, the customer’s budget is not strained.
Scope	All potential test scenarios are covered, making it exhaustive testing.	Test scenarios and innovative testing methods are given priority.

Crucial Aspects for Exhaustive Testing 

Following are some of the important aspects which every test engineer should keep in mind while carrying out exhaustive testing of a software application: 

1. Recovery Rate – Analyzing the application’s recovery rate both internally and with the development team. Determine which functionalities require thorough testing or comprehensive testing by ranking those with high and low recovery rates. 

2. Regression Testing – Every time a bug is fixed, a software tester must undertake regression testing to ensure that the other linked functionalities are still in operation. 

3. Business Impact – The exhaustive testing process is made simpler and more efficient with the help of this aspect. The business analyst might be contacted by the testing team to find out what would happen if some functionalities failed on the other modules. This will make it easier to analyses the application’s risk to the business. 

4. Failure Probability – This crucial aspect determines which functionality has a higher probability of malfunction. Assume that the to and from column and the search button will receive the most inputs and clicks on any travel website. Regression testing for that module ought to be given top priority. 

5. Refreshing Test Cases – The test cases must always be revised by testers because they cannot always be the same. When writing test cases, the testing team makes an effort to account for all potential input values. 

6. Review Information – The testing team should consider feedback from coworkers, business analysts, managers, and everyone else involved with the application on an internal or external basis. The evaluations will aid in a thorough grasp of the prerequisites for applications. 

7. Focus Testing – Testing that is exhaustive should be focused on testing the particular component of the software application, meaning that the testing’s objective is to make testing simple and clear. When testing an application, testers can concentrate on the test cases. 

8. Ad hoc Testing – Making sure that ad hoc testing is also carried out towards the end of the software testing life cycle is important. By dissecting the application into smaller, independent modules, this testing assists in discovering flaws in every module that may be present. 

Conclusion 

In the end, to conclude this blog post, we can say even though exhaustive testing is seen as an impractical and unachievable approach, testers nonetheless endeavor to complete any testing that comes close to it. The approach might be time-consuming or expensive, but it is 100% successful. There is nothing left for the customer to select and complain about. If the aforementioned tactics are used, it is possible to obtain testing that is very close to exhaustive. Large projects, however, should always priorities smart work, which is where software strategies like extensible testing come into play. For various tasks, a seasoned tester will always select the best method.
