Describe the bug

Given two mappings to the same path with multiple different JmesPathMatcher matchers on the body, the incorrect match is returned depending on the order of the mapping in the mapping file.

Expected behavior:

The response for the request where all matchers match should be returned.

Test to reproduce

There are 4 example tests included here:

  • Example A (Fail): Two body matchers where one value differs in each mapping.
  • Example B (Pass): Same mappings as Example A just listed in the opposite order in the static mappings.
  • Example C (Fail): Different number of body matchers per mapping.
  • Example D (Pass): Same mappings as Example C, just listed in the opposite order in the static mappings.

Setup static mappings as follows:

    "Request": {
      "Path": "/examplea",

Run the dotnet global tool as follows (version 1.5.39):

dotnet-wiremock --Urls "http://*:8080" --ReadStaticMappings "true" --WireMockLogger "WireMockConsoleLogger"

Run the following PowerShell code to see results:

$resultA = Invoke-RestMethod `
  -Body '{ "requestId": "1", "value": "A" }}' `
  -ContentType "application/json" `
  -Method "Post" `
  -Uri "http://localhost:8080/examplea"

Write-Host "[Example A]: $($resultA.value)"

$resultB = Invoke-RestMethod `
  -Body '{ "requestId": "1", "value": "A" }}' `
  -ContentType "application/json" `
  -Method "Post" `
  -Uri "http://localhost:8080/exampleb"

Write-Host "[Example B]: $($resultB.value)"

$resultC = Invoke-RestMethod `
  -Body '{ "extra": "X", "requestId": "1", "value": "A" }}' `
  -ContentType "application/json" `
  -Method "Post" `
  -Uri "http://localhost:8080/examplec"

Write-Host "[Example C]: $($resultC.value)"

$resultD = Invoke-RestMethod `
  -Body '{ "extra": "X", "requestId": "1", "value": "A" }}' `
  -ContentType "application/json" `
  -Method "Post" `
  -Uri "http://localhost:8080/exampled"

Write-Host "[Example D]: $($resultD.value)"

Results show:

[Example A]: Fail
[Example B]: Pass
[Example C]: Fail
[Example D]: Pass

I think the internal logic defaults to OR because the MatchOperator should be case-sensitive.

Can you try using the value And instead of and ?

I can confirm that changing the casing of and to And does cause Example A to pass, however Example C still fails.

The current implementation has no logic yet to determine that in your case the Example_C_Pass match is the best of the two "C"-tests.

For now just use .AtPriority(...) --> give the Example_C_Pass a value of 1, and the other a value of 2 or higher.
