The automotive industry is undergoing a software testing shift with the rise of Software-Defined Vehicles (SDVs). Unlike traditional vehicles where software remains static throughout the car’s lifecycle, SDVs require dynamic software updates and a development process that supports continuous enhancement.
To achieve this, the focus must shift from outdated Hardware-in-the-Loop (HIL) testing to a more agile Software-in-the-Loop (SIL) approach, enabling testing earlier in the development process.
Why SIL Matters for SDVs
HIL testing on traditional ECU infrastructures has long been the norm, but it’s ill-suited for SDVs, where user-relevant upgrades and software updates are key. SIL testing allows engineers to simulate, test, and validate software independently of hardware, paving the way for:
- Faster detection of errors
- Increased speed to market
- Substantial cost savings
This approach mirrors best practices from industries like banking, where integrating testing into the software development process has been standard for years. By identifying bugs early, the cost and effort to resolve them are drastically reduced.
Integrating Testing into the Development Lifecycle
To fully embrace the potential of SIL, testing must be a continuous, integrated part of the development process. Automation plays a pivotal role here, ensuring that every build of software is rigorously tested as it’s developed. However, effective testing requires a balance:
- Conducting on-premise testing for hardware and software integration early
- Transitioning to cloud-based testing for scalable, virtualised regression tests once a stable baseline is established.
This hybrid approach allows for controlled testing environments while paving the way for advanced automation and simulation capabilities in the cloud.

Continuous Integration: A Game-Changer for Automotive Development
The automotive industry is moving away from traditional linear testing models, such as the V-model, where testing occurs in distinct phases. Instead, a more fluid, iterative process is emerging:
- Build, test, and deploy in parallel.
- Use tools like T-Plan to automate UI testing and orchestrate other tools in the Software Development Lifecycle (SDLC).
- Ensure continuous feedback through integrated systems like Jenkins and GIT.
Automation in continuous integration doesn’t just save time—it ensures 24/7 testing, providing immediate feedback on builds and accelerating time to market.
