gock issue while mocking Prometheus with URL escaped query parameters about gock HOT 3 OPEN

Hello @Ahmad-Faizan @denizgursoy

gock uses regexp.MatchString() to match query parameters (code).

Any chars that have a special meaning in a regular expression, like (, ) or +, need to be escaped:

// ...
MatchParam("query", `scalar\(testMetric\)`)
// ...

from gock.

Same happened when I try to match param of date type.
Encoded value: 2023-09-23T01%3A28%3A16%2B02%3A00
String value: 2023-09-23T01:28:16+02:00

from gock.

I just learnt that regexp.QuoteMeta method can be used escape special characters in a reqular expression

from gock.
