AWS Device Farm Jenkins Plugin

AWS Device Farm integration with Jenkins CI

This plugin provides AWS Device Farm functionality from your own Jenkins CI server:

It also provides the device state details specification if the checkboxs are checked. Otherwise, the default settings will be used:

It also can pull down all of the test artifacts (logs, screenshots, etc.) locally:

        "StringLike": {
          "iam:AWSServiceName": "devicefarm.amazonaws.com"
        }
      }
    }
  ]
}

16. Click “Apply Policy”.

Generating a proper IAM role

Note : Only applies when you want to access Device Farm through an IAM Role.

You need to create one Device Farm access role to access the Device Farm Resource and one User or Role depending upon how you are running Jenkins.

• Creating Device Farm Role.

1. Log into your AWS web console UI.
2. Click “Identity & Access Management”.
3. On the left-hand side of the screen, click “Roles”.
4. Click “Create Role”.
5. In the AWS service section select Ec2 and click on Next.
6. Under the Inline Policies header, search and click the “AWSDeviceFarmFullAccess ” policy.This will give complete device farm access.
7. Go the the summary page of the role and click on edit next to "Maximum CLI/API session duration" and select 8hrs. This sets the expiration of the session associated with the IAM role to 8 hrs.
8. Now you want to give the access to the role/user to assume this role Open the new role you have created in console and then click on "Trust Relationships" tab. Click on "Edit Trust Relationship" and enter the following policy :

{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Effect": "Allow",
      "Principal": {
        "AWS": "To be replaced by Arn of user/role running on the Jenkins machine",
        "Service": "devicefarm.amazonaws.com"
      },
      "Action": "sts:AssumeRole"
    }
  ]
}

• Setting up Role/User running Jenkins

1. We need to also give access

3. In the permission tab click on Create Policy.
4. Select STS in the service name, search for assume role in actions and select it.
5. In the Resources section enter the arn for the device farm role.
6. Click on review policy and then enter name and description and click on Create policy.

3. Input the Device Farm Run Configuration
4. Click "Generate Pipeline Script"

TroubleShooting

"Invalid Credentials" Error while validating Credentials

We validate two things: 1) If the credentials are valid, 2) and if they have access to AWS Device Farm

1. Log in to your Jenkins host.
2. If using access and secret key, Run "aws devicefarm list-projects" on the host running Jenkins using the AWS CLI. If this fails, first check you credentials. If they are correct, refer to the "Generating a proper IAM user" section to ensure that you have given Device Farm necessary credentials.
3. If you are using role ARN Run "aws sts assume-role --role-arn "EnterRoleArnHere --duration-seconds 28800" using the AWS CLI. If this fails, refer to the "Generating a proper IAM role" section to verify if the role has correct assume role permissions. Run "aws devicefarm list-projects" using the AWS CLI. If this fails, your role doesn't have access to device farm. Please re-verify the steps above.

Project section not being populated with the latest data

1. Verify that the Project you are looking for is visible by logging in to the Device Farm console.
2. If yes, go to the Jenkins -> Manage Jenkins -> Configure System -> AWS Device Farm section and click on Validate.
