# This tool regenerates `wpt_internal/webgpu/cts.html` using the currently
# checked-out version of the WebGPU CTS. It does the following:
#
#   - Extracts the "name" part of every expectation from WebGPUExpectations.
#   - Prepares the WebGPU checkout to run the gen_wpt_cts_html tool.
#   - Runs gen_wpt_cts_html with the appropriate metadata and the extracted
#     expectations names. This generates a cts.html file with the necessary
#     variants to cover the expectations in WebGPUExpectations.
#
# Note: If it fails, it's likely that updates are needed to make
# WebGPUExpectations match the latest CTS (e.g. perhaps test/case names or
# parameters have changed). Consult the error message for details.
