Ability to filter the stack trace

[aleclarson]

Clear and concise description of the problem

In some cases, stack traces contain a bunch of lines from third party packages, and I would prefer to omit those lines from the stack trace, as it's extremely unlikely that I need to be aware of them.

Suggested solution

Add an option like filterStack that takes a function that receives a file path and returns a boolean to indicate whether the stack frame should be removed from the trace. This is what I do in Saus (my Vite-based framework), and it works great.

@aleclarson Can you please update this link - it works great. ? I wanted to take a look into it.

Vitest already parses error stack traces, so this feature should be straightforward to implement. We can do the same thing we did for console log filtering: https://vitest.dev/config/#onconsolelog

export default defineConfig({
  test: {
    onStackTrace({ method, file, line, column }) {
      if(file.includes('unexpected')) return false
    }
  }
})

This is where parsing happens:

export function parseErrorStacktrace(e: ErrorWithDiff, options: StackTraceParserOptions = {}): ParsedStack[] {
