VHS is a webmocking framework for Erlang inspired by Ruby's vcr gem. In the moment it only supports the ibrowse http client, but support for other libraries should be easy to add.
ibrowse:start(),
vhs:configure(ibrowse, []),
vhs:use_cassette(doc_domain_test,
fun() ->
Response = ibrowse:send_req("http:https://www.iana.org/domains/example",
[],
get),
%% Uses the same structure of the mocked library.
{ok, Status, _Headers, Body} = Response,
?assert_equal(Status, "200"),
?assert(contains(Body, "Example Domain"))
end),
VHS uses Meck to wrap ibrowse's send_req function and check whether the request has
been performed already. The first time, vhs will record the request-response into a
file, for later calls.
The tests are using in etest. In order to run the tests locally you just have to run the following command:
./bin/test
This will spawn a static server, compile the code and run the tests.
Pull Request. And always add a test to account for the behavior change/Feature.
