#17. Verify

Sometimes we do not need to control the response. We just need to prove that our client made a call.

#Start the live demo server

telepact demo-server --port 8000

#Start the mock server

telepact mock --http-url http://localhost:8000/api --port 8001 --path /api

#Find `fn.verify_`

curl -s localhost:8001/api -d '[{}, {"fn.api_": {"includeInternal!": true}}]'

The entry looks like this:

{
  "fn.verify_": {
    "call": "_ext.Call_",
    "strictMatch!": "boolean",
    "count!": "union.CallCountCriteria_"
  }
}

For the _ext.Call_ shape, see the mock extensions guide.

#Verify before the call

Let's clear any old history first:

curl -s localhost:8001/api -d '[{}, {"fn.clearCalls_": {}}]'
curl -s localhost:8001/api -d '[{}, {"fn.verify_": {"call": {"fn.add": {"x": 7, "y": 8}}}}]'

Response:

[{}, {"ErrorVerificationFailure": {"reason": {"TooFewMatchingCalls": {"wanted": {"AtLeast": {"times": 1}}, "found": 0, "allCalls": []}}}}]

#Verify after the call

curl -s localhost:8001/api -d '[{}, {"fn.add": {"x": 7, "y": 8}}]'
curl -s localhost:8001/api -d '[{}, {"fn.verify_": {"call": {"fn.add": {"x": 7, "y": 8}}}}]'
