Cannot create a lookup to match empty params

respx/respx/patterns.py

Lines 502 to 507 in c76f632

	def M(*patterns: Pattern, **lookups: Any) -> Pattern:
	extras = None
	for pattern__lookup, value in lookups.items():
	if not value:
	continue

E.g. respx_mock.get("https://example.com", params__eq={}).mock(...) matches request with any query params including empty.
Looks like the value check must be more accurate.

respx version 0.19.2

Interesting, thanks for reporting @MaxKh .

This part of the params pattern code needs to be tested with your empty params dict case:

respx/respx/patterns.py

Lines 266 to 269 in 019a8a8

	def _eq(self, value: Any) -> Match:
	value_items = self._multi_items(self.value, parse_any=True)
	request_items = self._multi_items(value)
	return Match(value_items == request_items)

Finally had time to look at this, and you were right @MaxKh, the issue was the too loose value check resulting in a continue.

Should be fixed and merged soon.
