Run the AWS IoT Greengrass qualification suite - AWS IoT Greengrass

You are viewing the documentation for AWS IoT Greengrass Version 1. AWS IoT Greengrass Version 2 is the latest major version of AWS IoT Greengrass. For more information about using AWS IoT Greengrass Version 2, see the AWS IoT Greengrass V2 Developer Guide.

Run the AWS IoT Greengrass qualification suite

After you set the required configuration, you can start the tests. The runtime of the full test suite depends on your hardware. For reference, it takes approximately 30 minutes to complete the full test suite on a Raspberry Pi 3B.

The following example run-suite commands show you how to run the qualification tests for a device pool. A device pool is a set of identical devices.

IDT v3.0.0 and later
Run all test groups in a specified test suite.
devicetester_[linux | mac | win_x86-64] run-suite --suite-id GGQ_1.0.0 --pool-id <pool-id>

Use the list-suites command to list the test suites that are in the tests folder.

Run a specific test group in a test suite.
devicetester_[linux | mac | win_x86-64] run-suite --suite-id GGQ_1.0.0 --group-id <group-id> --pool-id <pool-id>

Use the list-groups command to list the test groups in a test suite.

Run a specific test case in a test group.
devicetester_[linux | mac | win_x86-64] run-suite --group-id <group-id> --test-id <test-id>
Run multiple test cases in a test group.
devicetester_[linux | mac | win_x86-64] run-suite --group-id <group-id> --test-id <test-id1>,<test-id2>
List the test cases in a test group.
devicetester_[linux | mac | win_x86-64] list-test-cases --group-id <group-id>

The options for the run-suite command are optional. For example, you can omit pool-id if you have only one device pool defined in your device.json file. Or, you can omit suite-id if you want to run the latest test suite version in the tests folder.

Note

IDT prompts you if a newer test suite version is available online. For more information, see Set the default update behavior.

For more information about run-suite and other IDT commands, see IDT for AWS IoT Greengrass commands.

IDT v2.3.0 and earlier
Run all test groups in a specified suite.
devicetester_[linux | mac | win_x86-64] run-suite --suite-id GGQ_1 --pool-id <pool-id>
Run a specific test group.
devicetester_[linux | mac | win_x86-64] run-suite --suite-id GGQ_1 --group-id <group-id> --pool-id <pool-id>

suite-id and pool-id are optional if you are running a single test suite on a single device pool. This means that you have only one device pool defined in your device.json file.

Check for Greengrass dependencies

We recommend that you run the dependency checker test group to make sure all Greengrass dependencies are installed before you run related test groups. For example:

  • Run ggcdependencies before running core qualification test groups.

  • Run containerdependencies before running container-specific test groups.

  • Run dockerdependencies before running Docker-specific test groups.

  • Run ggcstreammanagementdependencies before running stream manager-specific test groups.

Set the default update behavior

When you start a test run, IDT checks online for a newer test suite version. If one is available, IDT prompts you to update to the latest available version. You can set the upgrade-test-suite (or u) flag to control the default update behavior. Valid values are:

  • y. IDT downloads and uses the latest available version.

  • n (default). IDT uses the version specified in the suite-id option. If suite-id is not specified, IDT uses the latest version in the tests folder.

If you don't include the upgrade-test-suite flag, IDT prompts you when an update is available and waits 30 seconds for your input (y or n). If no input is entered, it defaults to n and continues running the tests.

The following examples show common use cases for this feature:

Automatically use the latest tests available for a test group.
devicetester_linux run-suite -u y --group-id mqtt --pool-id DevicePool1
Run tests in a specific test suite version.
devicetester_linux run-suite -u n --suite-id GGQ_1.0.0 --group-id mqtt --pool-id DevicePool1
Prompt for updates at runtime.
devicetester_linux run-suite --pool-id DevicePool1

IDT for AWS IoT Greengrass commands

The IDT commands are located in the <device-tester-extract-location>/bin directory. Use them for the following operations:

IDT v3.0.0 and later
help

Lists information about the specified command.

list-groups

Lists the groups in a given test suite.

list-suites

Lists the available test suites.

list-supported-products

Lists the supported products, in this case AWS IoT Greengrass versions, and test suite versions for the current IDT version.

list-test-cases

Lists the test cases in a given test group. The following option is supported:

  • group-id. The test group to search for. This option is required and must specify a single group.

run-suite

Runs a suite of tests on a pool of devices. The following are some supported options:

  • suite-id. The test suite version to run. If not specified, IDT uses the latest version in the tests folder.

  • group-id. The test groups to run, as a comma-separated list. If not specified, IDT runs all test groups in the test suite.

  • test-id. The test cases to run, as a comma-separated list. When specified, group-id must specify a single group.

  • pool-id. The device pool to test. You must specify a pool if you have multiple device pools defined in your device.json file.

  • upgrade-test-suite. Controls how test suite version updates are handled. Starting in IDT v3.0.0, IDT checks online for updated test suite versions. For more information, see Test suite versions.

  • stop-on-first-failure. Configures IDT to stop execution on the first failure. This option should be used with group-id to debug the specified test groups. Do not use this option when running a full test-suite to generate a qualification report.

  • update-idt. Sets the response for the prompt to update IDT. Y as input stops the test execution if IDT detects there is a newer version. N as input continues the test execution.

  • update-managed-policy. Y as input stops the test execution if IDT detects that the user's managed policy isn’t updated. N as input continues the test execution.
