Put the following dependency into your project's dependences section:


DUB Package codecov

A library to allow integration testing of vibe.web.rest based code as unittests.


The main source file is extensively documented, and includes many unittests.

The straightforward approach is to do:

    static interface API
        @safe: // Vibe.d requirement, but LocalRest works with `@system`
        public @property ulong pubkey ();
        public string getValue (ulong idx);
        public ubyte[32] getQuorumSet ();
        public string recv (string data);

    static class MockAPI : API
        public override @property ulong pubkey ()
        { return 42; }
        public override string getValue (ulong idx)
        { assert(0); }
        public override ubyte[32] getQuorumSet ()
        { assert(0); }
        public override string recv (string data)
        { assert(0); }

    // This will start a new thread, create a `MockAPI` object in it,
    // and return a handle that allows communicating with it.
    scope API test = RemoteAPI!API.spawn!MockAPI();
    // Note that the handle will be of type `RemoteAPI!API`, which implements `API`
    // This is so one can have an array of `API`, but different underlying implementations.

    // This will send a message to the remote thread, which will ultimately call `MockAPI.pubkey`
    // Any parameter and return value is serialized to a type that is safe to pass accross thread.
    // By default, Vibe.d's JSON serializer is used, but it can be replaced (see `geod24.Serialization`).
    assert(test.pubkey() == 42);

    // Remote nodes can be controlled, to extend testing parameters:
    // For example, they can be made to be unresponsive for a set duration,
    // or to ignore calls to certain methods.

For this to work, one need to have Vibe.d already fetched. For a simple test, dub fetch vibe-d will suffice. For project depending on this, make sure your dub.json includes the following in dependencies:
