Case Study #1: the need for automated coverage analysis
Test case design and production are mostly manual activities that occupy up to 70% of the time over the lifecycle of a software test. Test cases prepared by inexperienced testers frequently do not adequately satisfy functional requirements. Additionally, requirement changes reveal the inability to reuse manually generated test cases, resulting in schedule slippage and expense increases. Numerous software projects employ some type of behavior-driven development to define requirements as they go from business stakeholders to plain language user stories.
User requirements must eventually be converted to natural language—so that they are easy for humans to comprehend and implement. Natural language test cases have limits due to the possibility of improper interpretation resulting in verification mistakes.
Traceability for user requirements and test cases can be established and utilized for requirement to test coverage analysis. End user technical documentation, which often covers features and functions, is never examined, and there is no mapping between test case techniques and technical documentation. To get understanding about high-end and sensitive systems that are controlled by professional operators, it is recommended to go to the end user technical paper. This highlights the critical nature of ensuring that the different areas/workflows stated in the technical specification are covered by the test procedures designed and identifying any gaps that may exist.
For any company developing software, quality control should stand out as a differentiating factor in ensuring the product's quality, stability, and resilience. To ensure optimal coverage of software features, it is necessary to write and implement suitable test procedures against the feature set. Traceability between product characteristics and test procedures is a demanding and complex task.
