Testgrid

The Kubernetes Testgrid instance is available at https://testgrid.k8s.io

We have a short video from the testgrid session at the 2018 contributor summit.

The video demos power features of testgrid, including:

  • Sorting
  • Filtering
  • Graphing
  • Grouping
  • Dashboard groups
  • Summaries
  • Clustered Failures

Please have a look!

Using the client

Here are some quick tips and clarifications for using the TestGrid site!

Tab Statuses

TestGrid assigns dashboard tabs a status based on recent test runs.

  • PASSING: No failures found in recent (num_columns_recent) test runs.
  • FAILING: One or more consistent failures in recent test runs.
  • FLAKY: The tab is neither PASSING nor FAILING. There is at least one recent failed result that is not a consistent failure.

Summary Widget

You can get a small widget showing the status of your dashboard tab, based on the tab statuses above! For example:

sig-testing-misc#bazel: sig-testing-misc/bazel

Inline it with:

<!-- Inline with a link to your tab -->
[![<dashboard_name>/<tab_name>](https://testgrid.k8s.io/q/summary/<dashboard_name>/<tab_name>/tests_status?style=svg)](https://testgrid.k8s.io/<dashboard_name>#<tab_name>)

Customizing Test Result Sizes

Change the size of the test result rectangles.

The three sizes are Standard, Compact, and Super Compact. You can also specify width=X in the URL (X > 3) to customize the width. For small widths, this may mean the date and/or changelist, or other custom headers, are no longer visible.

Filtering Tests

You can repeatedly add filters to include/exclude test rows. Under Options:

  • Include/Exclude Filter by RegEx: Specify a regular expression that matches test names for rows you'd like to include/exclude.
  • Exclude non-failed Tests: Omit rows with no failing results.

Grouping Tests

Grouped tests are summarized in a single row that is collapsible/expandable by clicking on the test name (shown as a triangle on the left). Under Options:

  • Group by RegEx Mask: Specify a regular expression to mask a portion of the test name. Any test names that match after applying this mask will be grouped together.

  • Group by Target: Any tests that contain the same target will be grouped together.

  • Group by Hierarchy Pattern: Specify a regular expression that matches one or more parts of the tests' names and the tests will be grouped hierarchically. For example, if you have these tests in your dashboard:

    /test/dir1/target1
/test/dir1/target2
/test/dir2/target3

    By specifying regular expression "\w+", the tests will be organized into:

    ▼test
  ▼dir1
    target1
  ▼dir2
    target2
    target3

Sorting Tests

Under Options

  • Sort by Failures: Tests with more recent failures will appear before other tests.
  • Sort by Flakiness: Tests with a higher flakiness score will appear before tests with a lower flakiness score. The flakiness score, which is not reported, is based on the number of transitions from passing to failing (and vice versa) with more weight given to more recent transitions.
  • Sort by Name: Sort alphabetically.

Clustered Failures

You can display identified clustered failures in your test results grid in a dashboard tab. Select the Display Clustered Failures List toggle button to render a list/table of identified failure clusters at the bottom of the browser.

Clusters can be grouped by:

  • test status
  • test status and error message

The clustered failures table shows the test status, error message (if grouped by error message), and area of the clusters. The clusters are sorted by area in descending order.

Selecting a row highlights the cells belonging to that cluster. Multiple row selection (with multiple cluster highlighting) is supported. To de-select a row, click on the selected row again.

Configuration

If you need to add a new test that you want TestGrid to display, or otherwise change what is shown on https://testgrid.k8s.io, see Testgrid Configuration.

Updates to the config are automatically tested and pushed to production.
