Test Case Generation in Insurance QA: Reaching Full Coverage
Introduction
In the realm of software and applications testing, one of the most critical objectives is achieving full coverage, ensuring that every possible scenario and combination is tested thoroughly. This ensures the robustness and reliability of the application under varying conditions. However, as systems grow in complexity, achieving full coverage becomes increasingly challenging. This blog explores the challenge of achieving full test coverage through combinatorial analysis and introduces Emtech QMT’s proprietary algorithms that effectively address this challenge.
The Challenge of Full Coverage
Consider a straightforward electronic application (eApp) with 30 questions, each having only two possible answers (e.g., Yes/No). On the surface, this might seem straightforward. However, when we delve into the mathematics of testing all possible combinations, the complexity quickly becomes evident. With each question having two possible answers, the total number of combinations is 230, or 1,073,741,824. Testing each of these combinations manually would be impractical, if not impossible. This illustrates the concept of combinatorial explosion, where the number of test cases increases exponentially with the number of inputs.
Achieving Full Coverage
To tackle the challenge of achieving full coverage, Emtech QMT employs two proprietary algorithms designed to intelligently generate test cases that cover every combination of every node at least once. These algorithms focus on two primary strategies: Maximum Coverage and Minimum Coverage.

Maximum Coverage
Maximum coverage aims to generate test cases that cover all possible combinations of paths. For our 30-question eApp example, this would mean creating 1,073,741,824 test cases, ensuring that every possible combination is tested. While this method guarantees exhaustive coverage, it is often impractical due to the immense resources required.
Benefits of Maximum Coverage
- Exhaustive Testing: Every possible combination is tested, ensuring no scenario is overlooked.
- High Confidence: Provides the highest level of assurance that the application will function correctly under any condition.
Minimum Coverage
Minimum coverage focuses on generating test cases that cover each path at least once. For the 30-question eApp, this results in 60 test cases (30 questions x 2 values), ensuring that each question and its possible answers are tested at least once.
Benefits of Minimum Coverage
- Efficiency: Drastically reduces the number of test cases, making the process more manageable.
- Practicality: More feasible for applications with many variables, allowing for thorough testing within a reasonable timeframe.
- Focused Testing: Ensures that all elements of the application are tested, though not in every possible combination.
Emtech QMT and Intelligent Test Case Generation
Emtech QMT’s proprietary algorithms offer a sophisticated solution to the challenge of achieving full coverage. By leveraging advanced combinatorial analysis, these algorithms intelligently generate test cases that balance thoroughness and efficiency.
Algorithmic Approach
- Node Combinations: Each node (question) and its combinations (answers) are systematically tested to ensure every possible outcome is covered at least once.
- Dependency Management: Dependencies between questions are considered, ensuring that test cases reflect realistic and relevant combinations.
- Optimization: Redundant test cases are eliminated, focusing on unique and impactful combinations to streamline the testing process.
Benefits of Emtech QMT’s Algorithms
- Comprehensive Coverage: Ensures that all critical paths and combinations are tested, providing high confidence in the application’s reliability.
- Efficiency: Optimizes the number of test cases, balancing thoroughness with practicality.
- Scalability: Suitable for applications of any size, from simple forms to complex systems with numerous variables.
Real-World Application
In practice, these algorithms enable testing teams to achieve a high level of coverage without being overwhelmed by the sheer number of possible test cases. For instance, in an eApp with numerous decision points and dependencies, Emtech QMT’s algorithms can identify and test the most critical combinations, ensuring that the application performs correctly under a wide range of conditions without the need for exhaustive testing.
Advantages of Using Emtech QMT
QMT’s high-performance knowledge graph model-based approach enables shift-left, allowing the entire QA cycle to be reduced to a few hours instead of weeks or months.
- Improved Product Launches: QMT discovers all defects early, delivering the level of quality needed to meet product launch dates.
- Full coverage at a fraction of the cost: Using a knowledge graph model removes manual testing, human error and extends visibility of QA for new products to well-informed business analysts.
- Reduce quality-related day-2 issues: QMT enables IT executives to get more value from the dollars spent by testing 100 percent of the value chain, providing the fewest quality-related Day 2 Issues, and reducing the inherent risks.
- Model Complex Policy Life Cycles: By testing the end-to-end process of insurance systems, and the integrations between them, carriers, InsurTechs and software vendors can drive quality into product launches and eliminate embarrassing errors experienced by distributors and customers post-launch.
Emtech’s Unique Approach to Quality Engineering
Emtech takes a unique approach to quality engineering that further enhances the benefits of test case generation. Emtech’s modeler maps business logic, enabling intelligent test case generation and automatic updating of tests when graphs change. This approach uses a low-code method for testing business logic and workflow, which improves QA efficiency, reduces costs, and enhances customer satisfaction.
By integrating intelligent test case generation, Emtech ensures that all possible scenarios are covered, reducing the likelihood of defects slipping through the cracks. The automatic updating of tests ensures that any changes in the business logic are immediately reflected in the test cases, maintaining alignment between development and testing. This reduces the manual effort required to update tests and minimizes the risk of human error.
The low-code method for testing business logic and workflow allows non-technical team members to contribute to the testing process, fostering a more inclusive and collaborative environment. This approach also speeds up the testing process, as it reduces the need for extensive coding and allows for quicker adjustments.
Emtech’s QMT significantly improves QA efficiency. By automating many of the testing processes, QMT reduces the time and effort required for testing, allowing teams to focus on more critical tasks. This leads to faster delivery times and lower costs, as fewer resources are needed for testing. Enhanced customer satisfaction is another key benefit of QMT. By ensuring higher quality and more reliable software, Emtech helps maintain a strong and positive brand image. Customers are more likely to trust and recommend insurance carriers that consistently meet their needs and perform reliably.
Final Thoughts
Achieving full coverage in test case generation is a complex but essential task for ensuring the reliability and performance of applications. Emtech QMT’s proprietary algorithms enable full coverage that intelligently test every variation of every node at least once. Model reusability provides the flexibility to tailor directly to what’s important to the business.
By leveraging these advanced algorithms, you can achieve a high level of confidence in insurance application’s ability to handle every possible condition, ultimately leading to a more robust and reliable product. In an era where insurance applications complexity continues to grow, intelligent test case generation is crucial for maintaining quality and performance in an increasingly demanding market.
