Device Advisor workflow - AWS IoT Core

Device Advisor workflow

This tutorial provides instructions on how to create a custom test suite and run tests against the device you want to test in the console. After the tests are complete, you can view the test results and detailed logs.

Prerequisites

To complete this tutorial, complete the steps outlined in Setting up.

Create a test suite definition

First, install an AWS SDK.

rootGroup syntax

A root group is a JSON string that specifies which test cases are included in your test suite and any necessary configurations for those test cases. Use the root group to structure and order your test suite in any way you like. The hierarchy of a test suite is:

test suite → test group(s) → test case(s)

A test suite must have at least one test group, and each test group must have at least one test case. Device Advisor runs tests in the order in which you define the test groups and test cases.

Each root group has this basic structure:

{ "configuration": { // for all tests in the test suite "": "" } "tests": [{ "name": "" "configuration": { // for all sub-groups in this test group "": "" }, "tests": [{ "name": "" "configuration": { // for all test cases in this test group "": "" }, "test": { "id": "" "version": "" } }] }] }

A block that contains a "name", "configuration", and "tests" is referred to as a "group definition". A block that contains a "name", "configuration", and "test" is referred to as a "test case definition". Each "test" block that contains an "id" and "version" is referred to as a "test case".

For information on how to fill in the "id" and "version" fields for each test case ("test" block), see Device Advisor test cases. That section also contains information on the available "configuration" settings.

The following is an example of a root group configuration that specifies the "MQTT Connect Happy Case" and "MQTT Connect Exponential Backoff Retries" test cases along with descriptions of the configuration fields.

{ "configuration": {}, // Suite-level configuration "tests": [ // Group definitions should be provided here { "name": "My_MQTT_Connect_Group", // Group definition name "configuration": {} // Group definition-level configuration, "tests": [ // Test case definitions should be provided here { "name": "My_MQTT_Connect_Happy_Case", // Test case definition name "configuration": { "EXECUTION_TIMEOUT": 300 // Test case definition-level configuration, in seconds }, "test": { "id": "MQTT_Connect", // test case id "version": "0.0.0" // test case version } }, { "name": "My_MQTT_Connect_Jitter_Backoff_Retries", // Test case definition name "configuration": { "EXECUTION_TIMEOUT": 600 // Test case definition-level configuration, in seconds }, "test": { "id": "MQTT_Connect_Jitter_Backoff_Retries", // test case id "version": "0.0.0" // test case version } }] }] }

You must supply the root group configuration when you create your test suite definition. Save the suiteDefinitionId that is returned in the response object—it's used to retrieve your test suite definition information and to run your test suite.

Here is a Java SDK example:

response = iotDeviceAdvisorClient.createSuiteDefinition( CreateSuiteDefinitionRequest.builder() .suiteDefinitionConfiguration(SuiteDefinitionConfiguration.builder() .suiteDefinitionName("your-suite-definition-name") .devices( DeviceUnderTest.builder() .thingArn("your-test-device-thing-arn") .certificateArn("your-test-device-certificate-arn") .build() ) .rootGroup("your-root-group-configuration") .devicePermissionRoleArn("your-device-permission-role-arn") .build() ) .build() )

Get a test suite run

After you create your test suite definition, you receive the suiteDefinitionId in the response object of the CreateSuiteDefinition API.

You may see that there are new id fields within each of the group and test case definitions in the root group that is returned. This is expected and you can use these IDs to run a subset of your test suite definition.

Java SDK example:

response = iotDeviceAdvisorClient.GetSuiteDefinition( GetSuiteDefinitionRequest.builder() .suiteDefinitionId("your-suite-definition-id") .build() )

Start a test suite run

After you've successfully created a test suite definition and configured your test device to connect to your Device Advisor test endpoint, run your test suite with the StartSuiteRun API. Use either certificateArn or thingArn to run the test suite. If both are configured, the certificate will be used if it belongs to the thing.

SDK example:

response = iotDeviceAdvisorClient.startSuiteRun(StartSuiteRunRequest.builder() .suiteDefinitionId("your-suite-definition-id") .suiteRunConfiguration(SuiteRunConfiguration.builder() .primaryDevice(DeviceUnderTest.builder() .certificateArn("your-test-device-certificate-arn") .thingArn("your-test-device-thing-arn") .build()) .build()) .build())

Save the suiteRunId that is returned in the response—you will use this to retrieve the results of this test suite run.

Get a test suite definition

After you start a test suite run, you can check its progress and its results with the GetSuiteRun API.

SDK example:

// Using the SDK, call the GetSuiteRun API. response = iotDeviceAdvisorClient.GetSuiteRun( GetSuiteRunRequest.builder() .suiteDefinitionId("your-suite-definition-id") .suiteRunId("your-suite-run-id") .build())

Stop a test suite run

AWS IoT Device Advisor allows one active test suite run at a time. To stop a test suite run still in progress, you can call the StopSuiteRun API. After you call the StopSuiteRun API, the service will start the cleanup process. While the service is running the cleanup process, test suite run status will be Stopping. The cleanup process will take several minutes, and once the process is complete, the test suite run will have the Stopped status. After a test run has completely stopped you will be able to start another test suite run. You can periodically check the suite run status using the GetSuiteRun API as shown in the previous section.

SDK example:

// Using the SDK, call the StopSuiteRun API. response = iotDeviceAdvisorClient.StopSuiteRun( StopSuiteRun.builder() .suiteDefinitionId("your-suite-definition-id") .suiteRunId("your-suite-run-id") .build())

Get a qualification report for a successful qualification test suite run

If you run a qualification test suite that completes, you can retrieve a qualification report by using the GetSuiteRunReport API. You can use this qualification report to qualify your device with the AWS IoT Core qualification program. To determine whether your test suite is a qualification test suite, check whether the intendedForQualification parameter is set to true. After you call the GetSuiteRunReport API, the download URL returned is available for you to download for 90 seconds. If more than 90 seconds elapse from the previous time you called the GetSuiteRunReport API, call the API again to retrieve a valid URL.

SDK example:

// Using the SDK, call the getSuiteRunReport API. response = iotDeviceAdvisorClient.getSuiteRunReport( GetSuiteRunReportRequest.builder() .suiteDefinitionId("your-suite-definition-id") .suiteRunId("your-suite-run-id") .build() )
