mock - API and testing utility¶

mock is an API utility - it lets you:

define API routes easily through API configuration files or through command-line parameters.
use shells scripts as response handlers. Or any other type of program can act as response handlers.
test your API - make assertions on whether an endpoint was requested.

Quick Links

Let’s look at a simple example - an API with 2 routes GET say_hi/{name} and GET what_time_is_it:

$ mock serve --port 3000 \
  --route 'say_hi/{name}' \
  --method GET \
  --response 'Hello, world! My name is ${name}.' \
  --route "what_time_is_it" \
  --method GET \
  --exec 'printf "Now it is %s" $(date +"%H:%M") | mock write'

Now try requesting your mock API at port 3000 (can also be from your browser!):

$ curl localhost:3000/say_hi/john_doe

Hello, world! My name is john_doe.

$ curl localhost:3000/what_time_is_it

Now it is 22:00

mock lets you also extend other APIs (or any HTTP service, for that matter.) Suppose you want to add a new route to an existing API running at example.com:

$ mock serve --port 3000 \
  --base example.com \
  --route 'some_new_route' \
  --method GET \
  --exec 'printf "Hello, world!" | mock write'

With the --base example.com option above, your mock API will act as proxy to that other website, and extend it with an extra route GET /some_new_route. Look up “Base APIs” in the docs for more details.

There are many other ways of further customising your APIs with mock. Read further through this guide to learn.
