An Insightful Approach Towards Risk Calculation
Software testers often face crunch situations while going through the testing cycles. The situation becomes more complex when you need to run all of the test cases and include all the modules of an application while testing. In order to avoid such situations, you must prioritize your test. This can be done by risk-based testing. This approach for testing allows you to test most critical parts of the application first.
A test based on calculated risk using a risk assessment strategy is quite helpful. Having a complete understanding of the risk-based testing approach is not easy. However, there are a few key points that must be considered while calculating risks.
In general terms, risk associated with particular areas of an application is the cost of failure and the probability of failure taken together. There are areas in applications that have different probabilities of failures. The key lies in identifying those areas that are likely to be most affected by failures. You also need to find out the areas that can get damaged by these failures. However, those identifications can be easily made considering a few key points.
- Complex areas
- Recently Modified
- Using the latest technology
- Involves more number of people in the development
- Enforced or rushed development
- Prone to defects
- Frequently used
The above-mentioned points might not be comprehensive, as there are different areas of focus for each industry, application, or business. However, the areas can act as a starting point to identify the highest risk areas.
Once the most risky areas have been identified to test, you can reduce the number of test cases. This can be done by looking at the test cases and analyze the effect of test case failure. The effect could be destructive or just a hindrance.
It’s the job of every tester to make the application defect free, which is quite impossible. However, one must try to trace out the worst defects. This can be done by risk-based testing during crunch testing cycles.
