+The output shows that the pipeline successfully processed the log data. The `rows` field contains the processed data, and the `schema` field contains the schema information of the processed data. You can use this information to verify the correctness of the pipeline configuration.
+
+### Test a Failed Pipeline
+
+Assume that the pipeline configuration is as follows:
+
+
+```bash
+curl -X "POST" "http://localhost:4000/v1/events/pipelines/test" \
+     -H 'Content-Type: application/x-yaml' \
+     -d $'processors:
+  - date:
+      field: time
+      formats:
+        - "%Y-%m-%d %H:%M:%S%.3f"
+      ignore_missing: true
+  - gsub:
+      fields:
+        - message
+      pattern: "\\\."
+      replacement:
+        - "-"
+      ignore_missing: true
+
+transform:
+  - fields:
+      - message
+    type: string
+  - field: time
+    type: time
+    index: timestamp'
+```
+
+The pipeline configuration contains an error. The `gsub` Processor expects the `replacement` field to be a string, but the current configuration provides an array. As a result, the pipeline creation fails with the following error message:
+
+
+```json
+{"error":"Failed to parse pipeline: 'replacement' must be a string"}
+```
+
+Therefore, We need to modify the configuration of the `gsub` Processor and change the value of the `replacement` field to a string type.
+
+```bash
+curl -X "POST" "http://localhost:4000/v1/events/pipelines/test" \
+     -H 'Content-Type: application/x-yaml' \
+     -d $'processors:
+  - date:
+      field: time
+      formats:
+        - "%Y-%m-%d %H:%M:%S%.3f"
+      ignore_missing: true
+  - gsub:
+      fields:
+        - message
+      pattern: "\\\."
+      replacement: "-"
+      ignore_missing: true
+
+transform:
+  - fields:
+      - message
+    type: string
+  - field: time
+    type: time
+    index: timestamp'
+```
+
+The Pipeline has been successfully created at this point, and We can test the Pipeline using the `dryrun` interface. We will test it with erroneous log data where the value of the message field is in numeric format, causing the pipeline to fail during processing.
+
+
+```bash
+curl -X "POST" "http://localhost:4000/v1/events/pipelines/dryrun?pipeline_name=test" \
+     -H 'Content-Type: application/json' \
+     -d $'{"message": 1998.08,"time":"2024-05-25 20:16:37.217"}'
+
+{"error":"Failed to execute pipeline, reason: gsub processor: expect string or array string, but got Float64(1998.08)"}
+```
+
+The output indicates that the pipeline processing failed because the `gsub` Processor expects a string type rather than a floating-point number type. We need to adjust the format of the log data to ensure the pipeline can process it correctly.
+Let's change the value of the message field to a string type and test the pipeline again.
+
+```bash
+curl -X "POST" "http://localhost:4000/v1/events/pipelines/dryrun?pipeline_name=test" \
+     -H 'Content-Type: application/json' \
+     -d $'{"message": "1998.08","time":"2024-05-25 20:16:37.217"}'
+```
+
+At this point, the Pipeline processing is successful, and the output is as follows:
+
+```json
+{
+    "rows": [
+        [
+            {
+                "data_type": "STRING",
+                "key": "message",
+                "semantic_type": "FIELD",
+                "value": "1998-08"
+            },
+            {
+                "data_type": "TIMESTAMP_NANOSECOND",
+                "key": "time",
+                "semantic_type": "TIMESTAMP",
+                "value": "2024-05-25 20:16:37.217+0000"
+            }
+        ]
+    ],
+    "schema": [
+        {
+            "colume_type": "FIELD",
+            "data_type": "STRING",
+            "fulltext": false,
+            "name": "message"
+        },
+        {
+            "colume_type": "TIMESTAMP",
+            "data_type": "TIMESTAMP_NANOSECOND",
+            "fulltext": false,
+            "name": "time"
+        }
+    ]
+}
+```
+
+It can be seen that the `.` in the string `1998.08` has been replaced with `-`, indicating a successful processing of the Pipeline.

+
+### 测试 Pipeline 失败
+
+接下来，我们测试一个失败的 Pipeline。假设我们的 Pipeline 配置文件如下：
+
+```bash
+curl -X "POST" "http://localhost:4000/v1/events/pipelines/test" \
+     -H 'Content-Type: application/x-yaml' \
+     -d $'processors:
+  - date:
+      field: time
+      formats:
+        - "%Y-%m-%d %H:%M:%S%.3f"
+      ignore_missing: true
+  - gsub:
+      fields:
+        - message
+      pattern: "\\\."
+      replacement:
+        - "-"
+      ignore_missing: true
+
+transform:
+  - fields:
+      - message
+    type: string
+  - field: time
+    type: time
+    index: timestamp'
+```
+
+Pipeline 配置存在错误。`gsub` processor 期望 `replacement` 字段为字符串，但当前配置提供了一个数组。因此，管道创建失败，并显示以下错误消息：
+
+
+```json
+{"error":"Failed to parse pipeline: 'replacement' must be a string"}
+```
+
+因此，您需要修改 `gsub` processor 的配置，将 `replacement` 字段的值更改为字符串类型。
+
+```bash
+curl -X "POST" "http://localhost:4000/v1/events/pipelines/test" \
+     -H 'Content-Type: application/x-yaml' \
+     -d $'processors:
+  - date:
+      field: time
+      formats:
+        - "%Y-%m-%d %H:%M:%S%.3f"
+      ignore_missing: true
+  - gsub:
+      fields:
+        - message
+      pattern: "\\\."
+      replacement: "-"
+      ignore_missing: true
+
+transform:
+  - fields:
+      - message
+    type: string
+  - field: time
+    type: time
+    index: timestamp'
+```
+
+此时 Pipeline 创建成功，可以使用 `dryrun` 接口测试该 Pipeline。我们使用一个错误的日志数据来测试，message 字段的值为数字类型，这会导致 Pipeline 处理失败。
+
+```bash
+curl -X "POST" "http://localhost:4000/v1/events/pipelines/dryrun?pipeline_name=test" \
+     -H 'Content-Type: application/json' \
+     -d $'{"message": 1998.08,"time":"2024-05-25 20:16:37.217"}'
+
+{"error":"Failed to execute pipeline, reason: gsub processor: expect string or array string, but got Float64(1998.08)"}
+```
+
+输出显示 Pipeline 处理失败，因为 `gsub` Processor 期望的是字符串类型，而不是浮点数类型。我们需要修改日志数据的格式，确保 Pipeline 能够正确处理。
+我们再将 message 字段的值修改为字符串类型，然后再次测试该 Pipeline。
+
+```bash
+curl -X "POST" "http://localhost:4000/v1/events/pipelines/dryrun?pipeline_name=test" \
+     -H 'Content-Type: application/json' \
+     -d $'{"message": "1998.08","time":"2024-05-25 20:16:37.217"}'
+```
+
+此时 Pipeline 处理成功，输出如下：
+
+```json
+{
+    "rows": [
+        [
+            {
+                "data_type": "STRING",
+                "key": "message",
+                "semantic_type": "FIELD",
+                "value": "1998-08"
+            },
+            {
+                "data_type": "TIMESTAMP_NANOSECOND",
+                "key": "time",
+                "semantic_type": "TIMESTAMP",
+                "value": "2024-05-25 20:16:37.217+0000"
+            }
+        ]
+    ],
+    "schema": [
+        {
+            "colume_type": "FIELD",
+            "data_type": "STRING",
+            "fulltext": false,
+            "name": "message"
+        },
+        {
+            "colume_type": "TIMESTAMP",
+            "data_type": "TIMESTAMP_NANOSECOND",
+            "fulltext": false,
+            "name": "time"
+        }
+    ]
+}
+```
+
+可以看到，`1998.08` 字符串中的 `.` 已经被替换为 `-`，Pipeline 处理成功。
