During my career as a Software Tester, I have gained extensive hands-on experience with exploratory testing methodologies. In my previous role as a Quality Assurance Engineer at XYZ Company, I used exploratory testing to identify critical defects in the application which were previously missed by our automated testing suites.
Through these instances and numerous other examples, I have learned that exploratory testing has become an essential aspect of any software testing process. It helps us identify defects that would otherwise go unnoticed by automated testing tools, and discovering those can be critical to the success of the product.
As an exploratory tester, prioritizing tests is a crucial part of ensuring that the most important aspects of the product are thoroughly tested. The following are the criteria I use to determine which tests to explore first:
Business impact: I prioritize tests based on the potential impact on the business. For example, if a product feature is critical to the success of the business, it will be tested first.
Criticality: Another important factor is the criticality of the feature or functionality. For instance, if a certain application feature is essential and could lead to significant financial loss, I prioritize testing it early on.
Risk level: High-risk areas are prioritized first to ensure that any risks are minimized. If a particular feature has failed in the past or is known to be prone to issues, it will be tested early on.
Customer impact: I prioritize tests based on the customer experience. For example, if a feature directly impacts the customer experience, it will be tested early.
Frequency of use: The most frequently used features of the application will be prioritized so that any issues that may affect the user's experience can be resolved quickly.
Defect history: I go through previous defect reports to identify any recurring issues and prioritize testing these areas to prevent any future issues.
Time constraints: I work closely with the project manager and development team to determine any upcoming deadlines and prioritize tests based on which features need to be released first.
Test coverage: I prioritize tests based on which areas of the application have not been tested extensively in previous testing cycles.
Resource availability: I evaluate the available resources and create a testing plan that optimizes the available resources while ensuring that the priority tests are covered.
Effective communication: Lastly, I prioritize tests based on the importance of effectively communicating results to the development team. Feedback loop between the two parties is critical for timely delivery and robust products.
Using these criteria, I can prioritize which tests to explore first, ensuring that the product is thoroughly tested while optimizing available resources and delivering meaningful results to the development team.
As a QA Engineer, my process for exploratory testing involves the following steps:
Throughout the process, I use test case management software to track the results of tests I have executed. For example, in my previous role, I successfully identified five major UI bugs in a new feature through exploratory testing. By finding these issues early in the development lifecycle, and providing detailed documentation on how to reproduce the bugs, helped in decreasing the bugs in the product by 50% over the next two sprints. Also, by updating the testing plan, we were able to eliminate most of the design bugs and server issues in the final product.
During exploratory testing, I employ a variety of strategies to identify defects. One key strategy is to use mind maps to organize my exploration process. By visualizing the test coverage and mapping out the testing areas, I can ensure that I am considering all possible scenarios and paths through the software.
In addition to mind maps, I also use heuristic testing methods. By applying a set of heuristics to the software, I can quickly identify areas that may pose a higher risk for defects. For example, I may focus on testing areas of the software that are especially complex or that have undergone recent changes.
I also use tools to assist in my defect identification. For example, I use both automation tools and manual testing approaches to gather data on the software's behavior. By examining the results of automated tests and performing manual testing in areas that require a human touch, I can identify defects faster and more accurately.
I'm proud to say that one notable example of the effectiveness of these strategies was when I identified a critical defect in a mobile app during exploratory testing. The app was intended to work on both iOS and Android devices, but I found that it was crashing on Android devices under specific conditions. Through mind mapping, heuristic testing, and the use of tools, I was able to isolate the root cause of the issue and communicate it to the development team. This resulted in a timely fix that prevented widespread negative user experiences and saved the company an estimated $50,000 in lost revenue.
During my exploratory testing sessions, I prefer to use a combination of tools that best suits the project requirements.
Overall, I am comfortable using various tools to perform exploratory testing and can adapt to new ones based on the project requirements. I am always on the lookout for new and better tools to help me improve and streamline my testing processes.
When dealing with time constraints while exploring a feature, I follow a structured approach to maximize efficiency:
These methods have proven to be effective within my previous roles. For instance, while testing a new feature for a mobile application under a tight deadline, I followed these steps to cover high priority scenarios and identified crucial defects which were addressed and resolved quickly. As a result, the feature was delivered on time and with high quality.
During exploratory testing, I make sure to follow a well-defined testing plan. I start by understanding the goals of the testing phase and defining the testing scope.
As a result of these methods, I can confidently say that I have been able to identify over 90% of critical defects during testing. In one project, I was able to find and log over 50 defects, which saved countless hours and saved my team from delivering products that did not meet the highest standards of quality.
During one of my exploratory testing sessions, I came across a critical problem with a website's checkout process. After selecting multiple items for purchase, the "Complete Order" button was not functioning properly, resulting in customers being unable to complete their orders.
This experience taught me the importance of exploratory testing in uncovering critical issues, and how effective communication and collaboration is crucial between development and testing teams to solve issues quickly and efficiently.
Collaborating with developers during exploratory testing is essential because it provides an opportunity to catch defects early in the development cycle. At the start of each project, I coordinate with the development team to establish a shared understanding of the product, its intended behavior, and objectives.
Overall, my approach to collaborating with developers during exploratory testing allows for a faster and more thorough testing process. By working in partnership with the development team, we can reduce defects and achieve a high level of product quality.
Exploratory testing is an essential part of my testing plan, and it involves much more than just clicking around haphazardly. When performing exploratory testing, I focus on looking for anomalies, edge cases, and behaviors that may not be immediately apparent. I also use heuristics and models to guide my testing.
Through this process, I have found several critical bugs that could have affected users severely. For example, I uncovered a network connectivity issue that prevented users in specific geographic locations from accessing critical features. By addressing this issue, we were able to increase our user base significantly and gain valuable insight into our product's usability.
