如何使用最小起订量对此操作进行单元测试

这个动作做了几件事，但我不知道从哪里开始 Moq，这里的新手。

        [Authorization.AppAuthorize]
    public ActionResult Form()
    {
        // Create a new Supplier request form
        StoreRequestViewModel requestForm = new StoreRequestViewModel();
        requestForm.OwnerGuid = Guid.NewGuid();
        // Keep in mind the request form ids
        this.Session[requestForm.OwnerSessionCacheKey] = requestForm as IRequestFormViewModel;
        SetupContext();
        return View("IndexForm", requestForm);
    }
