Mockingjay lets you define the contract between a consumer and producer and with just a configuration file you get:
- A fast to launch fake server for your integration tests
- Configurable to simulate the eratic nature of calling other services
- [Consumer driven contracts (CDCs)](http://martinfowler.com/articles/consumerDrivenContracts.html) to run against your real downstream services.
**Mockingjay makes it really easy to check your HTTP integration points**. It's fast, requires no coding and is better than other solutions because it will ensure your mock servers and real integration points are consistent so that you never have a green build but failing software.
- [Installation](https://github.com/quii/mockingjay-server/wiki/Installing) - [Download a binary](https://github.com/quii/mockingjay-server/releases/latest), [use a Docker image](https://hub.docker.com/r/quii/mockingjay-server/) or `go get`
- [Rationale](https://github.com/quii/mockingjay-server/wiki/Rationale)
- [See how mockingjay can easily fit into your workflow to make integration testing really easy and robust](https://github.com/quii/mockingjay-server/wiki/Suggested-workflow)
## Running a fake server
````yaml
---
- name: My very important integration point
request:
uri: /hello
method: POST
body: "Chris" # * matches any body
response:
code: 200
body: '{"message": "hello, Chris"}' # * matches any body
headers:
content-type: application/json
# define as many as you need...
````
````bash
$ mockingjay-server -config=example.yaml -port=1234 &
2015/04/13 14:27:54 Serving 3 endpoints defined from example.yaml on port 1234
$ curl http://localhost:1234/hello
{"message": "hello, world"}
````
## Check configuration is compatible with a real server
````bash
$ mockingjay-server -config=example.yaml -realURL=http://some-real-api.com
2015/04/13 21:06:06 Test endpoint (GET /hello) is incompatible with http://some-real-api - Couldn't reach real server
2015/04/13 21:06:06 Test endpoint 2 (DELETE /world) is incompatible with http://some-real-api - Couldn't reach real server
2015/04/13 21:06:06 Failing endpoint (POST /card) is incompatible with http://some-real-api - Couldn't reach real server
2015/04/13 21:06:06 At least one endpoint was incompatible with the real URL supplied
````
This ensures your integration test is working against a *reliable* fake.
### Inspect what requests mockingjay has received
http://{mockingjayhost}:{port}/requests
Calling this will return you a JSON list of requests
## Make your fake server flaky
Mockingjay has an annoying friend, a monkey. Given a monkey configuration you can make your fake service misbehave. This can be useful for performance tests where you want to simulate a more realistic scenario (i.e all integration points are painful).
````yaml
---
# Writes a different body 50% of the time
- body: "This is wrong :( "
frequency: 0.5
# Delays initial writing of response by a second 20% of the time
- delay: 1000
frequency: 0.2
# Returns a 404 30% of the time
- status: 404
frequency: 0.3
# Write 10,000,000 garbage bytes 9% of the time
- garbage: 10000000
frequency: 0.09
````
````bash
$ mockingjay-server -config=examples/example.yaml -monkeyConfig=examples/monkey-business.yaml
2015/04/17 14:19:53 Serving 3 endpoints defined from examples/example.yaml on port 9090
2015/04/17 14:19:53 Monkey config loaded
2015/04/17 14:19:53 50% of the time | Body: This is wrong :(
2015/04/17 14:19:53 20% of the time | Delay: 1s
2015/04/17 14:19:53 30% of the time | Status: 404
2015/04/17 14:19:53 9% of the time | Garbage bytes: 10000000
