verity

integration testing for http requests

features:

  • content-type matching
  • application/json response testing with colorized diffs
  • responses are verified holistically, for better reporting
  • supports cookies
  • supports login strategies
  • easy url manipulation

basic usage:

  var v = verity("http://localhost:8080/path/");
  v.jsonMode();
  v.method("POST");
  v.body({"some" : "json"});
  v.expectStatus(200);
  v.expectBody({"success" : true});
  v.test(function(err, result) {
    // err is present if any assertions failed.
    // result contains assertion errors, body, headers, status, and cookies
  });

or using the chained interface:

  var v = verity("http://localhost:8080/path/")
          .jsonMode()
          .method("POST")
          .body({"some" : "json"})
          .expectStatus(200)
          .expectBody({"success" : true})
          .test(function(err, result) {
            // ...
          });

api (instance methods):

jsonMode()

Call jsonMode() to allow json request and response bodies to be automatically serialized and deserialized into javascript objects.

body(String/Object)

Call body() to set the contents of the request body. This should be a string unless jsonMode() has been called.

method(String)

Call method() with an HTTP method to set the HTTP request method.

header(name, value)

Call header() with a header name and value to set a single http request header.

setCookieFromString(String)

Call `setCookieFromString()' to pass a cookie string to set the cookie values of the request.

expectStatus(Number)

Call expectStatus() to declare the HTTP status code that you expect the reponse to have.

expectHeaders(Object)

Call expectHeaders() expect certain headers. Unspecified headers will be ignored. Further calls will merge the two expectations.

expectCookie(Object)

Call expectCookie() expect certain cookies. Unspecified cookies will be ignored. Further calls will merge the two expectations.

expectBody(String/Object)

Call expectBody() to declare what bopdy to expect in the response. This should be a string unless jsonMode() has been called.

expectPartialBody(Object)

Call expectPartialBody() to expect certain response fields. Unspecified fields will be ignored. This method will error if JSON mode is not enabled.

expect(Function)

Call expect() to make your own assertions on the response. You must provide a function that takes the node response object, and throws an error if any expectations are violated. You may decorate the error with additional properties that will be logged.

test(cb)

Call test() to actually execute the specified request, and test your expectations. test() takes a callback that expects error and result arguments. The error parameter is truthy if the expectations were not met. The result parameter will contain an object detailing the errors, along with the response.

authStrategy(fn)

Call authStrategy with a function that takes a credentials object and a callback. This function should log a user into your app and return a cookie with proper session credentials.

login(credentials)

After authStrategy has been set, call login with a set of credentials to log a user in before running a test.

api (static methods):

assertObjectEquals(obj1, obj2)

Asserts that two objects are deeply-equal, and to throw an assertion error if they're not, along with logging the diffs.

register(fn)

Register your own expect helper, which you will be able to use in a manner similar to expectBody, expectHeaders, etc. Should return a function that takes the response object and throws an error if any assertions are not met. Attach your own properties to the thrown error object to add details.
