There was a problem hiding this comment.
The module.file || filename did not contain query params. module.id does. We need to have the query present in vm.RunningCodeOptions.filename so that V8 reports those files properly. Otherwise we would see same file URL multiple times, and could not identify which coverage belongs to which file transform.
Before:
{
scriptId: '305',
url: 'file:///Users/ari/Git/vitest/test/coverage-test/fixtures/src/query-param-transformed.ts',
functions: [...]
}
{
scriptId: '306',
url: 'file:///Users/ari/Git/vitest/test/coverage-test/fixtures/src/query-param-transformed.ts',
functions: [...]
}
{
scriptId: '307',
url: 'file:///Users/ari/Git/vitest/test/coverage-test/fixtures/src/query-param-transformed.ts',
functions: [...]
}After:
{
scriptId: '305',
url: 'file:///Users/ari/Git/vitest/test/coverage-test/fixtures/src/query-param-transformed.ts',
functions: [...]
}
{
scriptId: '306',
url: 'file:///Users/ari/Git/vitest/test/coverage-test/fixtures/src/query-param-transformed.ts%3Fquery=first',
functions: [...]
}
{
scriptId: '307',
url: 'file:///Users/ari/Git/vitest/test/coverage-test/fixtures/src/query-param-transformed.ts%3Fquery=second',
functions: [...]
}Note that the offset of functions there maps to different positions, based on query params.

Marking #6029 as linked too, as the minimal reproduction seems to work properly with this fix. I guess the auto-import does something with query params. |
