Create a test report in CodeBuild using the AWS CLI sample - AWS CodeBuild

Create a test report in CodeBuild using the AWS CLI sample

Tests that you specify in your buildspec file are run during your build. This sample shows you how to use the AWS CLI to incorporate tests into builds in CodeBuild. You can use JUnit to create unit tests, or you can use another tool to create configuration tests. You can then evaluate the test results to fix issues or optimize your application.

You can use the CodeBuild API or the AWS CodeBuild console to access the test results. This sample shows you how to configure your report so its test results are exported to an S3 bucket.


  • Create your test cases. This sample is written with the assumption that you have test cases to include in your sample test report. You specify the location of your test files in the buildspec file.

    The following test report file formats are supported:

    • Cucumber JSON

    • JUnit XML

    • NUnit XML

    • NUnit3 XML

    • TestNG XML

    • Visual Studio TRX

    Create your test cases with any test framework that can create report files in one of these formats (for example, Surefire JUnit plugin, TestNG, or Cucumber).

  • Create an S3 bucket and make a note of its name. For more information, see How do I create an S3 bucket? in the Amazon S3 User Guide.

  • Create an IAM role and make a note of its ARN. You need the ARN when you create your build project.

  • If your role does not have the following permissions, add them.

    { "Effect": "Allow", "Resource": [ "*" ], "Action": [ "codebuild:CreateReportGroup", "codebuild:CreateReport", "codebuild:UpdateReport", "codebuild:BatchPutTestCases" ] }

    For more information, see Permissions for test reporting operations.

Create a report group

  1. Create a file named CreateReportGroupInput.json.

  2. Create a folder in your S3 bucket where your test results are exported.

  3. Copy the following into CreateReportGroupInput.json. For <bucket-name>, use the name of the S3 bucket. For <path-to-folder>, enter the path to the folder in your S3 bucket.

    { "name": "<report-name>", "type": "TEST", "exportConfig": { "exportConfigType": "S3", "s3Destination": { "bucket": "<bucket-name>", "path": "<path-to-folder>", "packaging": "NONE" } } }
  4. Run the following command in the directory that contains CreateReportGroupInput.json.

    aws codebuild create-report-group --cli-input-json file://CreateReportGroupInput.json

    The output looks like the following. Make a note of the ARN for the reportGroup. You use it when you create a project that uses this report group.

    { "reportGroup": { "arn": "arn:aws:codebuild:us-west-2:123456789012:report-group/<report-name>", "name": "<report-name>", "type": "TEST", "exportConfig": { "exportConfigType": "S3", "s3Destination": { "bucket": "<s3-bucket-name>", "path": "<folder-path>", "packaging": "NONE", "encryptionKey": "arn:aws:kms:us-west-2:123456789012:alias/aws/s3" } }, "created": 1570837165.885, "lastModified": 1570837165.885 } }

Configure a project with a report group

To run a report, you first create a CodeBuild build project that is configured with your report group. Test cases specified for your report group are run when you run a build.

  1. Create a buildspec file named buildspec.yml.

  2. Use the following YAML as a template for your buildspec.yml file. Be sure to include the commands that run your tests. In the reports section, specify the files that contain the results of your test cases. These files store the test results you can access with CodeBuild. They expire 30 days after they are created. These files are different from the raw test case result files you export to an S3 bucket.

    version: 0.2 phases: install: runtime-versions: java: openjdk8 build: commands: - echo Running tests - <enter commands to run your tests> reports: <report-name-or-arn>: #test file information files: - '<test-result-files>' base-directory: '<optional-base-directory>' discard-paths: false #do not remove file paths from test result files

    Instead of the ARN of an existing report group, you can also specify a name for a report group that has not been created. If you specify a name instead of an ARN, CodeBuild creates a report group when it runs a build. Its name contains your project name and the name you specify in the buildspec file, in this format: project-name-report-group-name. For more information, see Create a test report and Report group naming.

  3. Create a file named project.json. This file contains input for the create-project command.

  4. Copy the following JSON into project.json. For source, enter the type and location of the repository that contains your source files. For serviceRole, specify the ARN of the role you are using.

    { "name": "test-report-project", "description": "sample-test-report-project", "source": { "type": "CODECOMMIT|CODEPIPELINE|GITHUB|S3|BITBUCKET|GITHUB_ENTERPRISE|NO_SOURCE", "location": "<your-source-url>" }, "artifacts": { "type": "NO_ARTIFACTS" }, "cache": { "type": "NO_CACHE" }, "environment": { "type": "LINUX_CONTAINER", "image": "aws/codebuild/standard:4.0", "computeType": "small" }, "serviceRole": "arn:aws:iam:<your-aws-account-id>:role/service-role/<your-role-name>" }
  5. Run the following command in the directory that contains project.json. This creates a project named test-project.

    aws codebuild create-project --cli-input-json file://project.json

Run and view results of a report

In this section, you run a build of the project you created earlier. During the build process, CodeBuild creates a report with the results of the test cases. The report is contained in the report group you specified.

  1. To start a build, run the following command. test-report-project is the name of the build project created above. Make a note of the build ID that appears in the output.

    aws codebuild start-build --project-name test-report-project
  2. Run the following command to get information about your build, including the ARN of your report. For <build-id>, specify your build ID. Make a note of the report ARN in the reportArns property of the output.

    aws codebuild batch-get-builds --ids <build-id>
  3. Run the following command to get details about your report. For <report-arn>, specify your report ARN.

    aws codebuild batch-get-reports --report-arns <report-arn>

    The output looks like the following. This sample output shows how many of the tests were successful, failed, skipped, resulted in an error, or return an unknown status.

    { "reports": [ { "status": "FAILED", "reportGroupArn": "<report-group-arn>", "name": "<report-group-name>", "created": 1573324770.154, "exportConfig": { "exportConfigType": "S3", "s3Destination": { "bucket": "<your-S3-bucket>", "path": "<path-to-your-report-results>", "packaging": "NONE", "encryptionKey": "<encryption-key>" } }, "expired": 1575916770.0, "truncated": false, "executionId": "arn:aws:codebuild:us-west-2:123456789012:build/<name-of-build-project>:2c254862-ddf6-4831-a53f-6839a73829c1", "type": "TEST", "arn": "<report-arn>", "testSummary": { "durationInNanoSeconds": 6657770, "total": 11, "statusCounts": { "FAILED": 3, "SKIPPED": 7, "ERROR": 0, "SUCCEEDED": 1, "UNKNOWN": 0 } } } ], "reportsNotFound": [] }
  4. Run the following command to list information about test cases for your report. For <report-arn>, specify the ARN of your report. For the optional --filter parameter, you can specify one status result (SUCCEEDED, FAILED, SKIPPED, ERROR, or UNKNOWN).

    aws codebuild describe-test-cases \ --report-arn <report-arn> \ --filter status=SUCCEEDED|FAILED|SKIPPED|ERROR|UNKNOWN

    The output looks like the following.

    { "testCases": [ { "status": "FAILED", "name": "Test case 1", "expired": 1575916770.0, "reportArn": "<report-arn>", "prefix": "Cucumber tests for agent", "message": "A test message", "durationInNanoSeconds": 1540540, "testRawDataPath": "<path-to-output-report-files>" }, { "status": "SUCCEEDED", "name": "Test case 2", "expired": 1575916770.0, "reportArn": "<report-arn>", "prefix": "Cucumber tests for agent", "message": "A test message", "durationInNanoSeconds": 1540540, "testRawDataPath": "<path-to-output-report-files>" } ] }
