Tutorial: Build and run the sample IDT test suite

The Amazon IoT Device Tester download includes the source code for a sample test suite. You can complete this tutorial to build and run the sample test suite to understand how you can use Amazon IoT Device Tester for Amazon IoT Greengrass to run custom test suites.

Prerequisites

To complete this tutorial, you need the following:

Configure device information for IDT

Configure your device information for IDT to run the test. You must update the device.json template located in the <device-tester-extract-location>/configs folder with the following information.

[
  {
    "id": "pool",
    "sku": "N/A",
    "devices": [
      {
        "id": "<device-id>",
        "connectivity": {
          "protocol": "ssh",
          "ip": "<ip-address>",
          "port": "<port>",
          "auth": {
            "method": "pki | password",
            "credentials": {
              "user": "<user-name>",
              "privKeyPath": "/path/to/private/key",
              "password": "<password>"
            }
          }
        }
      }
    ]
  }
]

In the devices object, provide the following information:

Build the sample test suite

The <device-tester-extract-location>/samples/python folder contains sample configuration files, source code, and the IDT Client SDK that you can combine into a test suite using the provided build scripts. The following directory tree shows the location of these sample files:

<device-tester-extract-location>
├── ...
├── tests
├── samples
│   ├── ...
│   └── python
│       ├── configuration
│       ├── src
│       └── build-scripts
│           ├── build.sh
│           └── build.ps1
└── sdks
    ├── ...
    └── python
        └── idt_client

To build the test suite, run the following commands on your host computer:

Windows

cd <device-tester-extract-location>/samples/python/build-scripts
./build.ps1

Linux, macOS, or UNIX

cd <device-tester-extract-location>/samples/python/build-scripts
./build.sh

This creates the sample test suite in the IDTSampleSuitePython_1.0.0 folder within the <device-tester-extract-location>/tests folder. Review the files in the IDTSampleSuitePython_1.0.0 folder to understand how the sample test suite is structured and see various examples of test case executables and test configuration JSON files.

Next step: Use IDT to run the sample test suite that you created.

Use IDT to run the sample test suite

To run the sample test suite, run the following commands on your host computer:

cd <device-tester-extract-location>/bin
./devicetester_[linux | mac | win_x86-64] run-suite --suite-id IDTSampleSuitePython

IDT runs the sample test suite and streams the results to the console. When the test has finished running, you see the following information:

Troubleshooting

Use the following information to help resolve any issues with completing the tutorial.

Test case does not run successfully

If the test does not run successfully, IDT streams the error logs to the console that can help you troubleshoot the test run. Make sure that you meet all the prerequisites for this tutorial.
