Automated Test System for Computer BIOS Using Capture and Replay

The patent applies preliminary action by capturing the test process in advance when the system is known to be correct. The capture module records test operations and expected results, creating a reference test process that can be automatically replayed later. This eliminates the need to manually re-execute tests after modifications, as the pre-captured test process serves as an automated verification tool.

The patent uses copying by creating a digital replica of the test process through the capture module. The captured test process including operations, timing, and expected results is stored as data that can be automatically replayed. This copy of the test process replaces manual testing execution, allowing automated verification without human intervention while maintaining testing thoroughness.

The patent applies universality by designing a single integrated test system that performs multiple test functions. The capture module can capture various types of test operations (keyboard inputs, mouse operations, display outputs), and the replay module can execute all these captured test processes. This unified system replaces the need for multiple separate test programs, reducing device complexity while maintaining comprehensive testing coverage.

The patent merges multiple test functions into a single integrated system. The capture module consolidates different test operation types (input operations, output verification) into one module, and the replay module combines all replay functions. This merging approach reduces the number of separate test programs needed while maintaining full testing coverage through the unified test process.

The patent applies self-service by enabling the test system to automatically execute and verify test processes without human intervention. The replay module automatically retrieves captured test processes, reproduces the test operations, and compares actual results with expected results. This self-service capability maintains testing accuracy through automated verification while dramatically improving productivity by eliminating repetitive manual operations.

The patent uses feedback by implementing an automated comparison mechanism where the replay module compares actual system responses with expected results from the captured test process. This feedback loop automatically verifies testing accuracy by identifying any deviations between expected and actual behavior, maintaining precision while improving productivity through automated error detection and reporting.
