Agent class Null safety

Executes HTTP requests during application testing.

Agents create and execute test requests. For most cases, methods like get, post, put and delete are used to execute these requests. For more granular control, request creates a request object that can be configured in more detail.

Each Agent has a set of default values, such as headers, that it uses for each of its requests. When many test requests have common headers, it is preferable to create an Agent for the similar requests. For example, after authenticating a user during tests, an Agent can add the 'Authorization' header for that user to each of its requests.

The default constructor takes an Application and configures itself from that application's options. The application is typically provided by TestHarness. TestHarness contains a default agent. Example usage:

    void main() {
      final harness = TestHarness<MyChannel>()..install();

      test("GET /thing returns 200", () async {
        final resp = await harness.agent.get("/thing");
        expect(resp, hasStatus(200));
      });
    }

Constructors

Agent(Application<ApplicationChannel?>? app)
Configures a new agent that sends requests to app.
Agent.from(Agent original)
Configures a new agent with the same properties as original.
Agent.fromOptions(ApplicationOptions config, {bool useHTTPS = false})
Configures a new agent that sends requests to a server configured by config.
Agent.onPort(int? _port)
