Tools looks great! I've added an issue here for openapi: https://github.com/boyney123/mockit/issues/5 . I have quite a few specifications in openapi v2 (swagger). It'd be helpful to support both v2 and v3 (as op requested) of the OpenAPI format.
Yeah I'm not sure I would use it for automated tests, you kind of want something abit more "robust" for those tests. This tool was designed to help get people off the ground, but I guess there is no reason why you could'nt use it for automated tests etc. Not sure I would!
Seems like a more featureful version of something I wrote a long while ago to ease testing, fakettp: github.com/sethgrid/fakettp. Mine requires a json config and can act as a proxy, intercepting given paths and overriding responses. Not sure if I added dynamic response based on an http header. The post's utility seems really polished with a nice ui.
Perhaps a set of sliders for each type of issue which define how often they might appear. E.G I don't care about 500s right now but would like 50% of the requests to be slow.
It touched my heart :( I worked more than one year on a service virtualization project in my previous job with 6-7 people and it has never been used by a real customer because of really bad management. I am still so angry. Our product was able to scale thanks to nomad+docker and had a cool ui to configure services such as rest, swagger, plain http etc.
We currently use a lot of API blueprint and drakov for this. But having options like monkeys in it would be a very nice thing! kinda thinking if there is a middleware for this though.
It doesn't have a nice GUI like this, but it is extremely flexible in the information you can match on for returning your mocked responses.
