Non Functional Testing Services

Elevate the performance of your Software with a structured approach to Non-Functional Testing.

Assess performance, resilience, security, accessibility and usability against agreed requirements. Identify the conditions under which the application slows down, fails or becomes difficult to use, and give the team evidence to prioritise improvements.

AI-enabled workloads

Consider response time, capacity, rate limits, dependency failures and consumption costs. Check what users see when an AI service is unavailable and whether the application can recover without losing or repeating work.

LET'S TALK
How We Can Help

Set the conditions before you test.

Agree the expected workload, user journeys, operating conditions and acceptance criteria. Include the behaviour people experience when a dependency slows down or fails. For accessibility, combine suitable automated checks with human evaluation and document the scope and remaining limitations.

Performance Testing

 

  • Evaluate the speed, responsiveness, and efficiency of your software application.
  • Measure system response times to ensure optimal performance.
  • Identify performance bottlenecks and optimise resource utilisation.
  • Validate software stability under different load conditions.
  • Fine-tune application performance for optimal user experience.

Load Testing

 

  • Assess system performance under anticipated loads to ensure scalability.
  • Simulate high user traffic and workloads to measure system behaviour.
  • Identify system limitations and capacity thresholds.
  • Measure reliability during representative peak usage periods.
  • Optimise infrastructure to handle increased user demand.

Security Testing

 

  • Identify vulnerabilities and assess software resilience against security threats.
  • Evaluate authentication, authorisation, and data protection mechanisms.
  • Test for potential breaches, unauthorised access, and data integrity issues.
  • Assess agreed security requirements and document evidence and gaps.
  • Enhance software defences to safeguard against potential attacks.

Usability Testing

 

  • Validate user-friendliness and ease of interaction with your software.
  • Assess user satisfaction, intuitiveness, and accessibility.
  • Identify usability issues, such as confusing navigation or unclear instructions.
  • Optimise UI design for an enhanced user experience.
  • Ensure software aligns with audience expectations and preferences.

Compatibility Testing

 

  • Verify software functionality across various platforms, devices, and operating systems.
  • Test compatibility with different browsers, screen resolutions, and mobile devices.
  • Ensure consistent behaviour across diverse hardware and software configurations.
  • Identify compatibility issues and provide necessary fixes or workarounds.
  • Maximise software reach by catering to a wide range of user environments.

Stress Testing

 

  • Push software to its limits to determine stability and performance under extreme conditions.
  • Test application behaviour under high concurrent user loads.
  • Evaluate system response during resource scarcity or failure scenarios.
  • Identify potential memory leaks, crashes, or performance degradation.
  • Optimise software resilience and recovery mechanisms for uninterrupted operation.
