Automating BIOS Testing: From coreboot to UEFI

BIOS testing is a critical yet complex part of firmware development. Whether you're working with open-source solutions like coreboot or industry-standard UEFI firmware, manual BIOS testing quickly becomes unmanageable as the number of configurations and updates increases. Testing firmware manually does not scale efficiently—you can only test more firmware or hardware linearly by adding more people, making automation essential. Automating BIOS testing significantly improves efficiency, reliability, and product quality.

The Complexity of BIOS Firmware Testing

Testing BIOS firmware manually involves numerous challenges:

Limited Scalability: Manual testing can only scale linearly with the number of people, making it unsustainable for large projects.
Human Error and Inconsistency: Manual testing introduces variability and potential for human error, complicating issue identification.
Time-Consuming Manual Processes: Manual testing slows down development cycles and delays release timelines.

Advantages of Automated BIOS Testing

Automating BIOS testing provides substantial benefits:

Speed and Scalability: Run tests simultaneously across multiple hardware configurations, significantly accelerating the validation process.
Consistency and Accuracy: Automation ensures repeatable and accurate results.
Continuous Integration and Continuous Delivery (CI/CD): Seamlessly integrate automated tests into existing workflows for rapid and reliable firmware releases.

Coreboot Automation

Quickly verify boot integrity, hardware initialization, and payload execution.
Automate testing across various boards and chipsets supported by coreboot.
Ensure security features, like verified boot and TPM integration, function correctly.

FirmwareCI: Simplifying BIOS Automation

FirmwareCI provides a powerful platform tailored for automated BIOS testing:

Vendor-Agnostic Approach: FirmwareCI works seamlessly with firmware binaries from all vendors. Its black-box testing approach, using the firmware binaries directly rather than being part of the compilation or development process, ensures compatibility with any firmware SDK from IBVs or open-source firmware solutions.
Easy Setup: Define tests using straightforward YAML configurations.
Seamless Integration: Connect directly with GitHub, GitLab, and other CI/CD platforms.
Real-Time Reporting: Immediate feedback on firmware builds, making debugging faster and easier.
Automated Hardware Testing: Support for automated device flashing and power cycling to fully automate the testing process.
