I don’t think there’s a way to do it currently. tsd
relies on the TypeScript compiler to find errors, and using @ts-expect-error
suppresses the error from being reported at all.
I think this would be a good feature to add to a possible editor integration or an eslint plugin. For now, if the error squigglies are too bothersome for you, you could isolate all of your expectError
assertions to their own file.
Ok, i see. I wish the behavior of expectError in this regard was the same as for expectType: VSCode marks it as error only if expectType fails. So for expectError it should really mark it red only if expectError itself fails, that is, when the passed expression actually does not have an error.

See #196 for discussion on this.
For my test files, since a lot of testing is for ts errors, I don't want the errors to be flagged red in VSCode (since they are expected), so i used // @ts-nocheck. However, after this, all expectError(...) checks fail with "Expected an error, but found none". I also tried with // @ts-expect-error and // @ts-ignore, same problem.
Or is there any other way to tell VSCode not to flag expected errors and still have expectError(...) working correctly?
