创建基于 .NET 8 WPF 的桌面测试程序，支持配置通知接口、频道、标题和正文，并通过内置模板快速发送不同类型的测试消息。

实现服务检测、单次发送、自动定时发送、模板轮换、批量发送、非法频道切换和发送日志记录，便于验证 OmniNotify 本地消息 API 的基础行为与异常场景。

+# OmniNotifyTest
+
+OmniNotifyTest 是一个用于测试 OmniNotify 本地消息 API 的 WPF 桌面工具。
+
+## 功能
+
+- 手动向 OmniNotify 发送单条通知
+- 编辑目标地址、频道、标题和正文
+- 使用内置模板测试普通消息、长文本、空标题、特殊字符和告警内容
+- 自动定时发送，可选择轮换模板
+- 快速批量发送，用于测试限流和熔断
+- 一键切换到通常不存在的频道，用于测试 `IllegalChannel`
+- 记录每次请求的时间、频道、标题、HTTP 状态和响应结果
+
+## 运行
+
+先启动 OmniNotify，并确保需要测试的频道已经在 OmniNotify 主程序中创建。
+
+```powershell
+dotnet run
+```
+
+默认发送地址为：
+
+```text
+http://127.0.0.1:19845/notify
+```
+
+OmniNotify 接收的 JSON 结构：
+
+```json
+{
+  "channel": "default",
+  "title": "测试通知",
+  "body": "这是一条测试消息。"
+}
+```
