Summary

  • Wire up the it-category input, which integration-tests.yml already read but never declared, so each matrix cell runs one of baseapi, dependent, workflow or other instead of the full suite in a single job.
  • Add the missing integration-tests-other profile. The existing category profiles only match packages under operator-framework, so without it the 10 ITs in other modules and at the root package would stop running.
  • Limit the PR matrix to Java 17/25 and Kubernetes v1.34.11/v1.37.0 (16 jobs, each much shorter than the previous 12 full-suite jobs).

Notes

  • Counting *IT.java by path gives 88 baseapi, 40 dependent, 16 workflow, 10 other, which is all 154, each in exactly one category.
  • Not yet run on CI, so the resulting timings are unmeasured.
  • Job names now include the category, so any required status checks matching the old names need updating.
  • httpclient-tests still runs the full suite in one job (experimental, does not fail the PR).
  • Java 21 and Kubernetes v1.35/v1.36 are no longer covered on PRs, and nothing else runs the full matrix.

Summary by CodeRabbit

  • Tests
    • Integration tests can now be selected and reported by category, including a category for tests outside the base API, dependent, and workflow groups.
    • The test matrix now covers Java 17 and 25 with Kubernetes v1.34.11 and v1.37.0. Java 21 and Kubernetes v1.35.8 and v1.36.4 are no longer included.

Wire up the unused it-category input so each matrix cell runs only one
of baseapi, dependent, workflow or other tests, and add the missing
integration-tests-other profile so ITs outside those packages still run.
Limit PR runs to the oldest and newest Java and Kubernetes versions.

Walkthrough

The build matrix now uses Java 17 and 25, Kubernetes v1.34.11 and v1.37.0, and four integration-test categories. The reusable workflow accepts and displays the selected category. A Maven profile selects other integration tests.

Changes: Integration test categories

Layer / File(s) Summary
Category input and test selection
.github/workflows/build.yml, .github/workflows/integration-tests.yml, pom.xml
The build matrix adds the baseapi, dependent, workflow, and other categories and passes the selected category to the reusable workflow. The workflow accepts an optional category and adds nonempty categories to the job name. The integration-tests-other Maven profile selects integration tests while excluding unit tests, end-to-end tests, and the base API, dependent, and workflow integration-test packages.

Suggested reviewers: xstefank, metacosm

Merge Risk: Low · up to 74960

A mistyped category can produce a passing build without integration tests. The current matrix uses valid values, so the risk is limited to other or future callers.

What changed in this PR

This PR splits integration tests into category-specific CI jobs and reduces the Java/Kubernetes combinations tested on pull requests.

Changes:

  • Runs four test categories across Java 17/25 and Kubernetes v1.34.11/v1.37.0, producing 16 matrix jobs.
  • Adds an integration-tests-other Maven profile to cover tests outside the three existing categories.
  • Declares the reusable workflow’s category input and includes it in job names.
File Description
pom.xml Adds the profile for integration tests outside baseapi, dependent, and workflow packages.
.github/​workflows/​integration-tests.yml Declares the category input and adds it to job names.
.github/​workflows/​build.yml Adds category-based jobs and narrows Java/Kubernetes version coverage.

Review effort: Balanced

Reject unknown integration-test categories.

If a caller mistypes it-category, Maven 3.10.0 only warns that the profile does not exist. The build can pass with no integration tests. (raw.githubusercontent.com)

Validate the category before selecting the profile.
