Testing

Testing

Dart already has fantastic testing support, through a library of testing helpers that will make test writing faster. The following functions are exported by package:angel_test, and will make your testing much easier.

connectTo

This function will start app on an available port, and return a TestClient instance (based on package:angel_client) configured to send requests to the server. The client also supports session manipulation.
1
main() {
2
TestClient client;
3
4
setUp(() async {
5
client = await connectTo(myApp);
6
});
7
8
// Shut down server, and cancel pending requests
9
tearDown(() => client.close());
10
11
test('hello', () async {
12
// The server URL is automatically prepended to paths.
13
// This returns an http.Response. :)
14
var response = await client.get('/hello');
15
});
16
}

isJson

A Matcher that asserts that the given http.Response equals value when decoded as JSON. This uses test.equals internally, so anything that would pass that matcher passes this one.

hasStatus

A Matcher that asserts the given http.Response has the given status code.
