go/analysis/analysistest: Ignore error if edited file can't be formatted

Open sourya opened this issue 4 years ago • 8 comments

There are instances when the diagnostics are reported correctly by the analyzer, but the suggested fixes are wrong, and result in code that cannot be formatted by format.Source (due to errors in the edited code). Right now, in those cases, the tests pass despite the format errors. This commit fixes that.

I think it's definitely a problem that we don't even check suggested fixes if the file can't be formatted, so I think that instead of just continuing we should check against the unformatted code.

It's tricky to just outright fail if the file can't be formatted. Consider a file that has a syntax error, and someone makes a resilient analyzer that can make suggested fixes even in the presence of syntax errors. This change could make it difficult to test an analyzer like that.

Hm, I'm not sure if this is right either. Most likely the message will be ignored.

I'm wondering if we can do the following: if the file fails to format, we check if the original file was able to be formatted: a suggested fix shouldn't break previously working code.
