Unlike scenario-based testing, exploratory testing is a software testing approach that relies on ad-hoc testing. Often described as simultaneous learning, test design and test execution, exploratory testing is not guided by test cases that are defined by user stories. Instead, testers rely on their own intuition and experience to test a software product to uncover bugs that are not easily covered in the scope of other tests.
Exploratory testing should not be confused with monkey testing, which aim to test the robustness and resilience of a product. Exploratory tests are not intended to push a software product to its breaking point but rather to go through it by putting oneself in the shoes of a user. Exploratory tests allow us to verify that the product works as it was intended, and that the experience is simple and pleasant.
Speed is one of the most significant benefits of exploratory testing. Exploratory testing allows developers and testers to continuously obtain relevant feedback that can be used to extend or strengthen their testing approach. Exploratory tests can be executed flexibly and even in real time since having test cases is not required. This approach allows testers to identify errors faster and provide feedback to developers in a minimum amount of time for maximum efficiency and to avoid the dreaded silo effect.
Not all tests should be automated. Performing exploratory testing allows testers to verify that the software works as expected beyond what is documented by developers and product managers. However, there are many things that simply cannot be evaluated by automated testing. This is the case when it comes to the user interface, usability, UX writing and even that little je ne sais quoi that immediately makes an application fun and enjoyable to use. Exploratory testing allows testers to be more creative and to evaluate the emotional and sensitive aspects of your product or service.
Testers are often required to run certain test cases that prevent them from examining the entire application, and the test cases become milestones that can cause them to lose sight of the purpose of each feature or even, more simply, the actual user journey. This is how big bugs can slip through the cracks of even the most seasoned testers. However, with exploratory testing, testers can freely evaluate the application to develop a better understanding of the product, its functionalities, etc. It's a way to take your head off the wheel and look at things from the perspective of a real user.
Exploratory testing can be beneficial in terms of retention, job satisfaction, and engagement of the testers who perform it. No one likes to run the same test cases over and over again. Solely using the scenario testing approach takes testers away from the product. They can end up feeling like they are just executing the same actions over and over again. Give your testers the opportunity to be brilliant, original, smart...or even just human.
With exploratory testing, experienced testers can use their skills to go beyond the established test cases to increase the scope of the testing process. It is important to note that the quality of exploratory testing depends on the expertise of the testers, because once the exploratory testing is done, the hardest part remains. Reporting clearly and simply on the difficulties encountered can be a real challenge. Thus, testers must pay special attention to communication and explain in a complete and detailed way the idea behind each test performed, but also the steps followed and the results obtained.
Last but not least, exploratory testing encourages and promotes dialogue between teams. Testers will be able to exchange with developers, product and marketing teams, who will be able to answer their questions and receive their more personal feedback.
