Configure the information of the mxpi_imageresize plugin to be tested in ${MX_SDK_HOME}/toolkit/TestPlugin/config/config.py. The configuration information is as follows:

If the plugin to be tested is a multi-input plugin, you can set multiple input files for the load configuration item.
If the plugin to be tested is a multi-output plugin, you can set multiple output files for the dump configuration item.

PipelineConfig = {
    "stream_config": {
        "deviceId": "0"
    },
    "factory": "mxpi_imageresize",      # Plugin name
    "props": {                          # Plugin properties
        "dataSource": "mxpi_imagedecoder0",
        "resizeHeight": "416",
        "resizeWidth": "416"
    },
    "load": [                           # Input file name of the load plugin. One input file corresponds to one load plugin.
        "input/imageresize0.json"
    ],
    "dump": [                           # Output file name of the dump plugin. One output file corresponds to one dump plugin.
        "imageresize0-output.json"
    ]
}

Create the data input file input/imageresize0.json for the plugin to be tested.

}

Run the single-plugin test tool to generate the pipeline file of the plugin to be tested and perform a stream test on the plugin. The command is as follows:
1

chmod +x run.sh && ./run.sh

The pipeline file is generated by the single-plugin test tool. Run the following commands:

       
            cat pipeline/mxpi_imageresize0.pipeline

{
    "TestPlugin": {
        "stream_config": {
            "deviceId": "0"
        },
        "mxpi_imageresize0": {
            "factory": "mxpi_imageresize",
            "next": [
                "mxpi_dumpdata0"
            ],
            "props": {
                "dataSource": "mxpi_imagedecoder0",
                "resizeHeight": "416",
                "resizeWidth": "416"
            }
        },
        "filesrc0": {
            "factory": "filesrc",
            "next": "mxpi_loaddata0",
            "props": {
                "location": "input/imageresize0.json",
                "blocksize": "40960000"
            }
        },
        "mxpi_loaddata0": {
            "factory": "mxpi_loaddata",
            "next": "mxpi_imageresize0:0"
        },
        "mxpi_dumpdata0": {
            "factory": "mxpi_dumpdata",
            "next": "fakesink0",
            "props": {
                "location": "imageresize0-output.json"
            }
        },
        "fakesink0": {
            "factory": "fakesink"
        }
    }
}

Check whether the output file imageresize0-output.json of the plugin to be tested has been generated by the single-plugin test tool.
Check the streaming result. If the streaming is successful, a success log is displayed, as shown in Figure 1.
