we shall discuss some best practices and approach of regression testing that will help in handling regression defects.
Make Sure that Rework is Avoided
Often, because of delivery deadline getting nearer, and pressure from the management to close the testing phase quickly, testers are forced to close certain minor bugs that have not been fixed. It is better to think about the long run. Make sure the job is done right the first time and it will reward you with a high-quality product and happier stakeholders, along with a short development lifecycle.
Make Sure Your Budget is Sufficient
It can be undoubtedly stated that regression testing is quite expensive. Companies have to spend a huge sum of money to test an application on which testing already has been performed. From the management’s point of view, they will see it pointless to invest such a huge sum since regression testing does not have any return on investment. Minimizing regression defects being your goal, your job is to explain the stakeholders properly, why they need to allow a specific budget if they are expecting a quality product.
Time Should Be Managed Efficiently
In the current Agile age, there is always pressure from the management to develop quality applications and deliver them faster. Certain phases of testing are often ignored and regression testing, unfortunately, falls among them. For minimizing regression defects, provide sufficient time to your testers so that they can execute the tests properly for controlling regression defects. Ultimately, speeding your test cycles.
Sort Test Cases According to Priority
Analyze the test cases and decide which are critical to business and which scenarios need to be tested first. Sort them in 3 categories
Priority 0 – Include sanity test cases that check basic functionality as per business requirement after a major change is done in an application.
Priority 1 – This should include the test scenarios that checks all the critical requirements and functionalities.
Priority 2 – The test cases included here should have moderate value to the project.
Prioritizing test cases will reduce the time complexity and help you in controlling regression defects.
Categorize The Test Cases
Controlling regression defects often becomes quite complex when the application has a larger scope and it requires the team to make frequent code changes. If you categorize the test cases, testing becomes easier and faster. Let’s see the 2 categories under which you can distribute your test cases.
Reusable – Test cases which are used repetitively in the regression cycle falls under this category.
Obsolete – Bug specific test cases that can only be used in a single test cycle can be categorized here.
Review With Your Team
While reviewing the fixed bug, not only testers, but the entire team – leads, developers and even program managers should participate evenly. This can cost a few hours but in the long run, it will reduce the cost of rework and retest. If the expectation bar is set quite high whenever a defect review is carried out, it will automatically help in minimizing regression defects.
Have An Entry And Exit Criteria
Set some conditions for entry criteria, like certain conditions based on bug review which should be met before initiating regression testing. For exit criteria, conditions, like executing all the tests and not keeping any defect unfixed, should be met before the test cycle is concluded. Having an entry/exit criteria just like traditional best practices of software testing will definitely help in minimizing regression defects.
Keep Certain “Surprise” Tests
Impose random testing often. You can make use of exploratory testing. This will ensure that testing has been executed in a proper manner. This should be performed especially after the test cycle has been completed. Test real-world scenarios in those random tests and you will be assured that a quality product is delivered to the stakeholders.
Bug Report Should Be Analyzed Properly
Latest regression testing tools will help you in creating bug reports as well as integrate the reports with those bug tracking tools. These tools also help you in capturing a screenshot while executing the test cases. Analyze the reports in detail and make sure that all of them gets fixed before concluding the test cycle for handling regression defects effectively.
Regression defects can be quite a time consuming and boring but they are crucial to deal with! We hope that the above-mentioned tips will help in making the process less monotonous and a lot faster for you to get the maximum output out of every release process. Let us know how you deal with regession defects in your organization. Happy bug hunting.
