Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If scripted automation is used to automate repetitive test cases, then efficiency is improved, but onboarding time and initial cost increase significantly
Solution Approach 1:
The system enables test automation through natural language input without requiring users to learn scripting languages. The AI model automatically converts English test scenarios into executable automation scripts, eliminating the need for manual code writing and significantly reducing onboarding time while maintaining high automation efficiency.
Solution Approach 2:
An AI language model acts as an intermediary between the user's natural language test descriptions and the automated test execution system. This intermediary automatically translates and converts the natural language input into structured automation scripts, bridging the gap between non-technical users and complex automation frameworks.
2Adaptability or versatility
If scripted automation is used to handle dynamic applications, then automation coverage is improved, but maintenance effort increases significantly
Solution Approach 1:
The system dynamically adapts to changes in applications and GUIs by using AI-based interpretation of natural language test cases. When applications evolve, the system can automatically adjust by reinterpreting the same natural language test scenarios against the new application state, eliminating the need for manual script updates and reducing maintenance complexity.
Solution Approach 2:
The system changes the fundamental parameter of test automation from fixed scripted code to dynamic AI-based interpretation. By converting test cases from rigid programming language scripts to flexible natural language descriptions that are dynamically interpreted, the system adapts to application changes without requiring code modifications, significantly reducing maintenance effort.
3Measurement precision
If reference image-based comparisons are used to validate GUI screens, then validation accuracy is improved, but adaptability to GUI changes decreases
Solution Approach 1:
Instead of comparing actual GUI screens against fixed reference images, the system inverts the approach by using AI to interpret natural language test cases and dynamically validate GUI elements. This inversion allows the validation to adapt to GUI changes while maintaining accuracy through semantic understanding rather than pixel-perfect matching.
Solution Approach 2:
The system replaces rigid reference image copies with AI-generated semantic representations of expected GUI states. Rather than storing and comparing fixed image snapshots, the system uses language models to create and compare semantic descriptions of GUI elements, allowing for flexible validation that adapts to legitimate GUI changes while maintaining validation accuracy.
4Ease of operation
If low-code systems with predefined logic are used, then ease of operation is improved, but flexibility for dynamic decisions decreases
Solution Approach 1:
The system provides self-service capabilities by automatically generating and executing test automation scripts from natural language input without requiring users to work within predefined logic blocks. The AI model autonomously handles the conversion and execution, providing both ease of operation and the flexibility needed for dynamic decision-making in test scenarios.
Solution Approach 2:
The AI-based system serves multiple functions: it parses natural language, generates automation scripts, executes tests, and adapts to various application types and GUI changes. This universal approach replaces the need for predefined logic blocks with a single flexible system that can handle diverse testing scenarios while maintaining ease of use through natural language input.

AI summary
A natural language-based no-code test automation system is provided. The test automation system includes natural language-based test cases and an app description file including a natural language description of a particular test application run on test devices. An intelligent test execution engine includes an orchestrator configured to convert the natural language-based test cases into actions to be performed for testing the test application on the test devices using the app description file and a large language model subsystem implementing large language models. The orchestrator maps each of the actions to a corresponding test application interface call in the test automation system using one or more of the large language models, and automatically tests the test application by iteratively executing each of the actions via the corresponding test application interface call.
