View tests

Your CI pipelines can run tests in Run steps and Test steps. In Harness, test results can be published to the Build details page on either the Tests tab or the Artifacts tab.

Publish reports to the Tests tab​

To publish test results and view them in Harness, you must produce test reports in JUnit XML format and add the Report Paths specification to the step, for example:

              - step:
                  type: Run
                  name: Tests
                  identifier: tests
                  ...
                  reports:
                    type: JUnit
                    spec:
                      paths:
                        - /path/to/test/report.xml

The Tests tab can show tests only if your test reports are in JUnit XML format, because Harness parses test reports that are in JUnit XML format only. For information about formatting unit test reports, go to Format test reports.

After a build runs, you can review test reports on the Tests tab on the Build details page. The content differs for Run and Test steps.

Results from Run steps​

If you used a Run step, the Tests tab contains information about the total number of tests, the failure rate, and a list of failed tests. You can hover over individual failed test to view additional details about the failure.

If you ran tests in multiple steps/stages, or parallel steps/stages, use the Step/Stage dropdown menu to switch between reports from different steps or stages.

Results from Test steps with Test Intelligence​

If you are using Test Intelligence for your unit tests, the Tests tab contains information unique to Test Intelligence. In addition to the test results, you can also get information about which tests were selected by Test Intelligence and why Test Intelligence selected those tests.

info

The first run with TI doesn't include test selection, because Harness must establish a baseline for comparison in future runs. On subsequent runs, Harness can use the baseline to select relevant tests based on the content of the code changes.

Your first TI run won't report selected tests. Subsequent runs can report selected tests, if any are selected. For more information, go to Enable Test Intelligence.

Expand the sections below to learn more about the information available on the Tests tab for Test Intelligence.

Test Execution Overview

This section provides an overview of Total Tests, number of Selected Tests, total Duration of all tests, and Time Saved.

Duration reflects the sum of CPU time taken for all tests to complete. The values are collected as-is from the JUnit report, and they don't correspond with wall-clock time. In contrast, the pipeline execution time is a measure of wall-clock time. Therefore, it is possible that the Duration may exceed the total pipeline execution time.

Test Execution Result

This section provides a graphical representation of successful and failed tests.

Test Selection Breakdown

Test Intelligence analyzes changes to source files and test files in the codebase and then runs only the tests that are relevant to the detected changes. This section reports how many tests ran based on the different the types of code changes included in this build:

  • Correlated with Code Changes: The number of tests that ran due to changes in the codebase.
  • New Tests: The number of tests that ran because they are new.
  • Updated Tests: The number of tests that ran because there was a change to the actual test code or content.
Test Execution

This section provides a detailed list of all tests, including class methods and test methods.

Initially, the list shows only failed tests. To see all tests, toggle Show all Tests.

You can sort the list by failure rate, duration, and total tests. You can also expand test suites to see details about individual tests in that suite.

Call Graph

Select Expand graph to view the TI Visualization, which shows why a specific test was selected and the reason behind every test selection. Purple nodes represent tests. Select any test (purple node) to see all the classes and methods covered by that test. Blue nodes represent changes to classes and methods that caused TI to select that test.

The call graph can be empty if:

  • You just enabled Test Intelligence. Your first TI run won't report selected tests. Subsequent runs can report selected tests, if any are selected. The first run with TI doesn't include test selection, because Harness must establish a baseline for comparison in future runs. On subsequent runs, Harness can use the baseline to select relevant tests based on the content of the code changes.
  • TI selected all tests. Lots of code changes and changes to certain files cause TI to select all tests. In this case, no call graph is generated because it would be too large and not useful.

For more information about how and when TI selects tests, go to Enable Test Intelligence.

View reports on the Artifacts tab​

For reports that can't be published to the Tests tab, you can use the Artifact Metadata Publisher plugin to publish reports to the Artifacts tab on the Build details page. You can publish any URL to the Artifacts tab.

  1. Include steps in your pipeline that run tests and produce test reports.

  2. Add a step to upload the report artifact to cloud storage, such as:

  3. Add a Plugin step that uses the artifact-metadata-publisher plugin, for example:

                   - step:
                      type: Plugin
                      name: publish artifact metadata
                      identifier: publish_artifact_metadata
                      spec:
                        connectorRef: account.harnessImage ## Use the built-in Docker connector or specify your own Docker connector.
                        image: plugins/artifact-metadata-publisher ## Required.
                        settings:
                          file_urls: ## Provide the URL to the artifact that was uploaded in the Upload Artifacts step. If you uploaded multiple artifacts, you can provide a list of URLs.
                          artifact_file: artifact.txt ## Provide any '.txt' file name. Harness uses this to store the artifact URL and display it on the Artifacts tab. This value is not the name of your uploaded artifact, and it has no relationship to the artifact object itself.

Test report dashboard​

note

Currently, the Unit Test Metrics dashboard is behind the feature flag CI_TI_DASHBOARDS_ENABLED. Contact Harness Support to enable the feature.

The Unit Test Metrics dashboard aggregates data from test reports in JUnit XML format. The dashboard reports the overall failure rate and the overall success rate. The dashboard breaks down failure data by pipeline, Git repo, and test. You can filter by project, pipeline, and date range.

You can find this and other dashboards under the Dashboards section of your Harness account.
