Exploratory testing is gaining massive popularity in the software testing industry. This test explores the functionality of the software application and detects bugs that might be missed during the script-based test. It helps the QA team to analyze and evaluate the issues or errors in the software application based on their knowledge and perception. This does not require them to follow a strict path of test cases. Due to the high demand for faster release of software applications in the market, more companies are implementing exploratory testing as an integral part of their testing strategy.
Exploratory testing in regression testing is critical in identifying bugs or errors and ensuring that the application continues to behave as expected once changes are live. Regression testing discovers and fixes any unprecedented changes that might occur due to new amendments, bug fixes, or software updates.
Any changes or defects that have been previously missed can easily be identified through exploratory testing, ensuring that the software applications continue to work with correct functionality at their capacity.
In this blog, we’ll dig a bit deeper into this topic to understand the role of Exploratory Testing in Regression Testing and why it is essential.
Understanding Regression Testing
Imagine you have a well-functioning software that’s been tested thoroughly. Now, let’s say you make some changes or add new features. Regression testing comes into play to ensure that these modifications keep the existing functionality.
Regression testing aims to confirm that the software still behaves as expected after these changes. It’s like double-checking that everything works smoothly and that the tweaks didn’t break anything.
To achieve this, different techniques are used. One common approach is retesting, where previously tested parts of the software are tested again to ensure they haven’t been affected. Test cases are carefully selected and prioritized based on their impact and relevance to the changes made. Automation Testing also plays a role, making the process more efficient.
By employing these strategies, regression testing helps reduce the risk of introducing bugs or issues when modifying software. It ensures the stability and reliability of the system, giving you confidence that your software remains intact even with new updates.
Understanding Exploratory Testing
Exploratory testing is your approach to uncovering the hidden secrets of the software you’re testing. Instead of following a predefined set of test cases, you dive right in, exploring its functionalities and learning as you go.
This approach emphasizes flexibility and creativity. You design and execute tests on the fly, adapting as you discover new aspects of the software. It’s like embarking on an exciting journey, uncovering defects and issues along the way.
Early defect detection is one of the perks of exploratory testing. You can catch bugs that regression tests have yet to notice. You also achieve improved test coverage because you’re not limited to predefined scenarios. The dynamic nature of exploratory testing allows you to adapt and focus on areas that need more attention.
Role of Exploratory Testing in Regression Testing
Exploratory testing can contribute to the effectiveness and thoroughness of regression testing by providing a fresh perspective and uncovering potential defects that might have been missed through traditional regression testing approaches.
Here are some key points that highlight the role of exploratory testing in regression testing:
- Uncovering new defects: As stated above, Exploratory testing is necessary because it explores issues that were not tested earlier or are barely covered by standard test cases.
- Identifying areas of ambiguity for comprehensive testing: Explanatory testing in Regression testing adds an extra layer of authentication to identify areas of vulnerability that may require attention during regression testing.
- Verifying the fixes: Once the issues are resolved, exploratory testing helps verify that they’ve been appropriately implemented, thereby ensuring error-free testing.
- Help in providing feedback to the developers: Using Exploratory testing, testers can offer real feedback to the development team on the software’s performance and the user’s response. Utilizing this feedback will make the next build or release even better.
- Uncovering New Scenarios: Exploratory testing enables testers to approach the software from fresh angles, exploring uncharted territories that may have been missed in previous regression testing cycles. By actively investigating the software, testers can uncover new paths, interactions, and edge cases, unveiling regression defects that might have gone unnoticed. This proactive approach expands the coverage of regression testing and identifies potential issues that might have been overlooked.
- Adapting to Changes: Exploratory testing shines when changes or updates are made to the software. It helps validate the impact of these modifications on existing functionality and identifies unexpected regressions. Testers can dynamically create and execute tests, focusing on the areas that have been modified to ensure that the changes haven’t introduced new defects. The flexibility of exploratory testing makes it an indispensable component of regression testing, especially in agile or fast-paced development environments.
- Exploring Interactions: While regression testing often concentrates on testing individual components or features in isolation, exploratory testing allows testers to explore the interactions between different elements. This holistic perspective helps identify regression issues that may arise from integrating various software parts. Examining the system as a whole and observing how other elements interact allows testers to uncover regression defects that isolated regression tests may have missed.
- Finding Hidden Defects: The creative and flexible nature of exploratory testing empowers testers to think outside the box and discover hidden defects that regression tests may overlook. Testers leverage their skills, knowledge, and intuition to actively explore the software, increasing the chances of finding regression defects manifesting in unique scenarios. The exploratory mindset allows testers to identify unexpected issues, evaluate the software’s behavior from different user perspectives, and uncover regression defects that reveal themselves under specific conditions.
Exploratory testing brings fresh perspectives, adaptability, and creativity to regression testing. By embracing this approach, testers can enhance test coverage, adapt to changes effectively, explore interactions, and uncover hidden defects, ultimately improving the quality and robustness of the software.
