Test Automation Framework

Context

Testing activities across different .NET components, backend services, and workflow logic required repetitive manual execution. Variability in test steps and environments made validation slow, error-prone, and difficult to reproduce.

Challenge

A scalable method was needed to automate functional and integration testing across diverse systems: C# and VB.NET assemblies, APIs, data layers, and UI-driven processes. The solution had to remain generic, maintainable, and easy to extend without modifying the core framework.

Solution

A generic .NET automation framework was designed using an Excel-driven “TestSequence” matrix. Tests are executed dynamically via Reflection, enabling any .NET method to run without framework changes. Typed row mapping captures parameters, expected results, and execution metadata. The framework supports skip, pause, verify, and chained logic while writing real-time results and colour feedback back into Excel. Diagnostic output is streamed to an on-screen viewer and log files, enabling traceability and debugging.

Key Capabilities

• Dynamic execution of any .NET method (C# or VB.NET) via Reflection
• Excel-based orchestration with typed parameter and result mapping
• Skip / pause / manual-verify rows for flexible workflow modelling
• Chained-parameter logic using previous test outputs
• Instance caching for long-running or multi-step scenarios
• Full audit logging and real-time debug output
• Supports API calls, backend logic, UI extraction, and service wrappers

Impact

• Automation replaced repetitive manual testing, reduced execution time, and increased consistency across multi-system .NET workflows
• Release cycles became more predictable and lower risk
• Test scenarios became fully repeatable with clear traceability and audit trails
