Run tests matching CI configuration.
unit or no argument — unit tests./mvnw clean test -q -B -D"checkstyle.skip"
CI runs this on:
integration — integration tests (excludes slow)./mvnw -B clean integration-test -Dcheckstyle.skip -DskipUTs=true -DexcludedGroups=slow
CI runs this on JDK 11, 17, 21, 25 (ubuntu only).
slow — slow integration tests./mvnw -B clean integration-test -Dcheckstyle.skip -DskipUTs=true \
-Dit.test=org.apache.skywalking.library.elasticsearch.ElasticSearchIT \
-Dfailsafe.failIfNoSpecifiedTests=false
CI runs on JDK 11 (ubuntu only). Currently only ElasticSearch/OpenSearch IT is in the slow matrix.
# Unit tests for a specific module
./mvnw clean test -pl oap-server/analyzer/<module-name> -D"checkstyle.skip"
# Integration tests for a specific module
./mvnw -B clean integration-test -pl oap-server/analyzer/<module-name> -Dcheckstyle.skip -DskipUTs=true
org.junit.jupiter)| Type | Pattern | Maven phase |
|---|---|---|
| Unit tests | *Test.java | test |
| Integration tests | IT*.java or *IT.java | integration-test |
Tests tagged with @Tag("slow") are excluded from the normal integration-test job and run separately in the slow-integration-test job. Use this tag for tests that spin up external services (Elasticsearch, etc.) and take significant time.
All three CI jobs retry on failure (run the same command twice with ||). This handles flaky tests but masks intermittent issues — if a test fails locally, investigate rather than relying on retries.
CI workflow: .github/workflows/skywalking.yaml
| Job | JDK | OS | Timeout |
|---|---|---|---|
unit-test | 11 (3 OS) + 17, 21, 25 (ubuntu) | ubuntu, macOS, Windows | 30 min |
integration-test | 11, 17, 21, 25 | ubuntu | 60 min |
slow-integration-test | 11 | ubuntu | 60 min |
Verify, commit, and push changes on a PR branch. Runs pre-flight checks (compile, checkstyle, license headers) before every push. Also creates the PR if one doesn't exist yet.
Add a new monitoring target / layer to SkyWalking OAP. Orients you to the OAL / MAL / LAL / SpanListener / SegmentListener extension points, the UI template + submodule touchpoints, the docs set that must move together, and the cross-cutting traps that don't live in any one skill.
Run SkyWalking E2E tests locally
Rebuild the SkyWalking distribution and OAP Docker image after source changes. Use before running e2e tests so the image reflects your code changes. Avoids the "image looks updated but runtime has stale jars" trap.
Download and inspect CI e2e test logs from GitHub Actions artifacts. Use when investigating e2e test failures in CI.
Generate bytecode classes from DSL scripts (MAL, OAL, LAL, Hierarchy). Runs the compiler and dumps .class files for inspection.
