Feature request: wildcard in nested assertion

[Janpot]

I quite often find myself in need to assert for nested properties where the path isn't always fully known. Most of the times when I want to check whether a nested array contains an object with a certain property. Would it be possible to allow wildcards in the path?

// maybe something like
assert.nestedPropertyVal(obj, 'foo[?].bar', 'baz');
// or
assert.nestedPropertyVal(obj, 'foo[*].bar', 'baz');
// or maybe even with a regex
assert.nestedPropertyVal(obj, 'foo[/.*/].bar', 'baz');

Not sure if the feature should be included or not in chai core, but if you decide to go with it I'd prefer a less ambiguous API:

assert.nestedPropertyVal(obj, [/foo.*/s, 'bar'], 'baz');

Instead of requiring some special parsing, just materialize the property path with an array, use strings for constants and regexes for dynamic parts. This does not support "any-depth" matches (such as git's wildstar **) but you could add a symbol for it or just write you own chai plugin using something based on minimatch for this kind of advanced feature.

I agree on that point. But it already supports that kind of path notation, so special parsing is already happening.

Hey @Janpot thanks for the issue. Thanks for the extra comments @demurgos.

We'll look into adding this for Chai 5. We've added this to our Roadmap to investigate further. We'll be releasing chai 5 soon, but for now I'll close this issue because it is tracked on our roadmap.
