Following this instruction page - https://www.electronjs.org/docs/development/build-instructions-gn to build electron.
I made testing build config successfully using
gn gen out/Testing --args="import(\"//electron/build/args/testing.gn\")"
In the next step when I tried to build using ninja -C out/Testing electron it failed with following error -
FileNotFoundError: [Errno 2] No such file or directory: 'gen/third_party/dom_distiller_js/test_sample_json_converter.h'

I searched entire directory there is a file name with test_sample_json_converter.h.golden only.
I had the same issue, and it was due to the tag that I used (92.0.4505.0) missed this commit: https://chromium.googlesource.com/chromium/src.git/+/96ec10dd20f2d23e98f93c48991c6ad106308644.
(The problematic target was
gen/third_party/dom_distiller_js/json_values_converter_tests.stamp)
