Worked on the gpuweb/cts repository to enhance test suite alignment with evolving GPUWeb proposals, focusing on compatibility and reliability. Addressed multisampling issues for integer texture formats by updating TypeScript-based tests to disable multisampling where unsupported and skip tests on non-multisampled formats, reducing false negatives and improving CI outcomes. Leveraged skills in shader development, compatibility analysis, and testing to ensure the test suite accurately reflects current WebGPU guidelines. These targeted adjustments streamlined validation processes for new proposals, supporting stable and predictable test results. The work emphasized careful adherence to specification changes and contributed to more robust GPUWeb test infrastructure.
