Stub API. Stubs Upsert ​

Upsert (insert or update) stubs via the /api/stubs endpoint. This lets you add new stubs or update existing ones by specifying their id.

Example Contract (simple.proto) ​

proto
syntax = "proto3";

package simple;

service Gripmock {
  rpc SayHello (Request) returns (Reply);
}

message Request {
  string name = 1;
}

message Reply {
  string message = 1;
  int32 returnCode = 2;
}

Request ​

  • Method: POST
  • URL: /api/stubs
  • Headers: Content-Type: application/json
  • Body: A single Stub object or an array of Stub objects.

Examples ​

1. Create a Single Stub

bash
curl -X POST -d '{
  "service": "Gripmock",
  "method": "SayHello",
  "input": {
    "equals": { "name": "gripmock" }
  },
  "output": {
    "data": { "message": "Hello GripMock", "returnCode": 42 },
    "error": ""
  }
}' http://127.0.0.1:4771/api/stubs

Response (returns the generated id):

json
["6c85b0fa-caaf-4640-a672-f56b7dd8074d"]

2. Create Multiple Stubs (Batch)

bash
curl -X POST -d '[
  {
    "service": "Gripmock",
    "method": "SayHello",
    "input": { "equals": { "name": "gripmock1" } },
    "output": { "data": { "message": "Hello GripMock. stab1", "returnCode": 42 } }
  },
  {
    "service": "Gripmock",
    "method": "SayHello",
    "input": { "equals": { "name": "gripmock2" } },
    "output": { "data": { "message": "Hello GripMock. stab2", "returnCode": 42 } }
  }
]' http://127.0.0.1:4771/api/stubs

Response (returns generated ids for all stubs):

json
["2378ccb8-f36e-48b0-a257-4309876bed47", "0ee02a07-4cae-4a0b-b0c1-5e7c379bc858"]

Schema Details ​

  • Stub Object:
    json
    {
  "id": "string (optional, UUID format)",
  "service": "string (required, e.g., 'Gripmock')",
  "method": "string (required, e.g., 'SayHello')",
  "input": {
    "ignoreArrayOrder": "boolean (default: false)",
    "equals": { "key": "exact match value" },
    "contains": { "key": "partial match value" },
    "matches": { "key": "regex pattern" }
  },
  "output": {
    "data": { "key": "value (matches your protobuf Reply type)" },
    "error": "string (gRPC error message)",
    "code": "integer (gRPC status code, e.g., 3 for 'InvalidArgument')"
  }
}

Behavior ​

  • ID Handling:
    • If id is omitted, a new UUID is generated.
    • If id is provided and exists, the stub is updated.
  • Input Matching:
    • equals: Exact match for fields.
    • contains: Partial match (substring).
    • matches: Regex match.
  • Output:
    • data: Must align with your protobuf Reply message structure.
    • error and code: Define gRPC error responses.

Notes ​

  • Upsert Logic: Use this endpoint to create or update stubs.
  • Batch Support: Send an array of stubs in a single request.
  • Validation: Invalid stubs (e.g., missing service/method) return 400 Bad Request.
  • GET /api/stubs: List all stubs.
  • DELETE /api/stubs: Delete all stubs.
  • DELETE /api/stubs/{uuid}: Delete a specific stub by ID.
