wstest alternatives and similar packages
Based on the "Testing Frameworks" category
-
gospecify
This provides a BDD syntax for testing your Go code. It should be familiar to anybody who has used libraries such as rspec. -
Hamcrest
fluent framework for declarative Matcher objects that, when applied to input values, produce self-describing results. -
assert
Basic Assertion Library used along side native go testing, with building blocks for custom assertions -
gosuite
Brings lightweight test suites with setup/teardown facilities to testing by leveraging Go1.7's Subtests -
apitest
Simple and extensible behavioural testing library for REST based services or HTTP handlers that supports mocking external http calls and rendering of sequence diagrams.

wstest
A websocket client for unit-testing a websocket server
The gorilla organization provides full featured websocket implementation that the standard library lacks.
The standard library provides a httptest.ResponseRecorder struct that test
an http.Handler without ListenAndServe, but is helpless when the connection is being hijacked
by an http upgrader. As for testing websockets, it has the httptest.NewServer that actually
listens on a socket on an arbitrary port.
This package provides a NewDialer function to test just the http.Handler that upgrades
the connection to a websocket session. It runs the handler function in a goroutine
without listening on any port. The returned websocket.Dialer then can be used to dial and communicate
with the given handler.

go get -u github.com/posener/wstest
Examples
See the [example test](./example_test.go).
An example how to modify a test function from using
httptest.Server to use wstest.NewDialer function.
func TestHandler(t *testing.T) {
var err error
h := &myHandler{}
- s := httptest.NewServer(h)
- defer s.Close()
- d := websocket.Dialer{}
+ d := wstest.NewDialer(h)
- c, resp, err := d.Dial("ws://" + s.Listener.Addr().String() + "/ws", nil)
+ c, resp, err := d.Dial("ws://" + "whatever" + "/ws", nil)
if err != nil {
t.Fatal(err)
}
if got, want := resp.StatusCode, http.StatusSwitchingProtocols; got != want {
t.Errorf("resp.StatusCode = %q, want %q", got, want)
}
err = c.WriteJSON("test")
if err != nil {
t.Fatal(err)
}
}
