Hi. Is there a way to generate some random string matching particular pattern using

response-template

? eg:

[A-Z]{3}[0-9]{5}

should produce ABC12345, XYZ54321 etc

for the pattern in your query, you can do

{{randomValue length=3 type='ALPHABETIC'}}{{randomValue length=5 type='NUMERIC'}}

Great. TY @Rafe Arnold

more docs on wiremock's random helpers is here

Need one more help. The Stub i created always returns 200 response. Is there a way to arbitrarily send some failure response like 400, 404, 500 etc.

there is currently no way to have the same stub return different statuses. you can have multiple stubs that each return a different status and have each one match based on some detail of the request, say

/thing/1

returns a 200 whereas

/thing/2

will return a 404
