- **Focus**:
  1. Collection and processing of telemetry data.
  1. Interaction between telemetry components and Istio control plane.
  1. Validation of metrics collection and reporting.
  1. Testing of logging configurations and log collection.
  1. Validation of tracing and distributed tracing setups.
- **Setup**: The main test setup in this folder initializes the Istio control plane with telemetry configurations.

### Helm Integration Tests

该示例中，信息会在响应发出 *之后* 被写到 `log.txt` 文件。

如果请求中有查询，它将在后台任务中写入日志。

然后另一个在 *路径操作函数* 生成的后台任务会使用路径参数 `email` 写入一条信息。
