Previously only Exec tasks had this dependency, causing RemoteSymbolicationTest to fail with NoClassDefFoundError when RemoteSymHelper's static initializer couldn't load libddproftest.so. The fix changes from type-based matching (Exec only) to name-based matching (all tasks starting with "test"), ensuring both Test and Exec tasks wait for the native library to be built.

Changes: - Create Exec tasks directly for musl (no Test task wrapper) - Read test filters from -Ptests project property instead of --tests flag - Remove testdebugExec hidden task, use testdebug directly Known Issue: - musl + Liberica JDK 11 still fails with NoSuchMethodError when running JUnit Console Launcher. This appears to be a pre-existing issue with that specific JDK build. JDK 21 on musl works fine. Tested: - ✅ JDK 11 glibc: 144 tests run (Test task) - ✅ JDK 21 musl: Tests run (Exec task) - ❌ JDK 11 musl: NoSuchMethodError (JDK build issue) Co-Authored-By: Claude Sonnet 4.5 --- .../datadoghq/profiler/ProfilerTestPlugin.kt | 149 +++--------------- 1 file changed, 22 insertions(+), 127 deletions(-) diff --git a/build-logic/conventions/src/main/kotlin/com/datadoghq/profiler/ProfilerTestPlugin.kt b/build-logic/conventions/src/main/kotlin/com/datadoghq/profiler/ProfilerTestPlugin.kt index 1bdb77c72..f91a67551 100644 --- a/build-logic/conventions/src/main/kotlin/com/datadoghq/profiler/ProfilerTestPlugin.kt +++ b/build-logic/conventions/src/main/kotlin/com/datadoghq/profiler/ProfilerTestPlugin.kt @@ -182,35 +182,23 @@ class ProfilerTestPlugin : Plugin { testTask.dependsOn(testCfg) testTask.dependsOn(sourceSets.getByName("test").output) -

Changes: - Add ProfilerTestRunner with JUnit Platform Launcher API - Create Test tasks on glibc/macOS, Exec tasks on musl - Fix JDK 11 + musl by removing LD_LIBRARY_PATH (prevents cross-JDK library loading) - Support both . and # method separators with proper heuristic - Update all docs to use -Ptests syntax consistently - Add warning when --tests flag used on Test tasks - Switch from junit-platform-console to junit-platform-launcher - Add build-logic to Dependabot monitoring - Improve error handling in javadocJar task Verified on musl + JDK 11, musl + JDK 21, and macOS.

The `--tests` flag only works with Gradle's Test task type, but config-specific tasks (testDebug, testRelease) use Exec task type to bypass toolchain issues on musl systems. +**Note**: Use `-Ptests` (not `--tests`) with config-specific test tasks. The `-Ptests` property works uniformly across all platforms. On glibc/macOS, config-specific tasks use Gradle's Test task type. On musl systems, they use Exec task type to bypass toolchain probing issues. ### C++ Unit Tests (Google Test) diff --git a/gradle/libs.versions.toml b/gradle/libs.versions.toml index fbe5bd7bf..bcb79ee0b 100644 --- a/gradle/libs.versions.toml +++ b/gradle/libs.versions.toml @@ -29,7 +29,7 @@ jmh = "1.36" junit-api = { module = "org.junit.jupiter:junit-jupiter-api", version.ref = "junit" } junit-engine = { module = "org.junit.jupiter:junit-jupiter-engine", version.ref = "junit" } junit-params = { module = "org.junit.jupiter:junit-jupiter-params", version.ref = "junit" } -junit-platform-console = { module = "org.junit.platform:junit-platform-console", version.ref = "junit-platform" } +junit-platform-launcher = { module = "org.junit.platform:junit-platform-launcher", version.ref = "junit-platform" } junit-pioneer = { module = "org.junit-pioneer:junit-pioneer", version.ref = "junit-pioneer" } # Logging @@ -52,8 +52,8 @@ jmh-core = { module = "org.openjdk.jmh:jmh-core", version.ref = "jmh" } jmh-annprocess = { module = "org.openjdk.jmh:jmh-generator-annprocess", version.ref = "jmh" } [bundles] -# Core testing framework (JUnit + logging + console launcher for Exec tasks) -testing = ["junit-api", "junit-engine", "junit-params", "junit-platform-console", "junit-pioneer", "slf4j-simple"] +# Core testing framework (JUnit + logging + launcher API for custom test runner) +testing = ["junit-api", "junit-engine", "junit-params", "junit-platform-launcher", "junit-pioneer", "slf4j-simple"] # Profiler runtime dependencies (JFR analysis + compression) profiler-runtime = ["jmc-flightrecorder", "jol-core", "lz4", "snappy", "zstd"] diff --git a/utils/run-docker-tests.sh b/utils/run-docker-tests.sh index 7aff12678..3b60b7507 100755 --- a/utils/run-docker-tests.sh +++ b/utils/run-docker-tests.sh @@ -414,10 +414,11 @@ fi # ========== Run Tests ========== # Build gradle test command -# Note: --tests flag works uniformly across all platforms (glibc, musl, macOS) +# Note: -Ptests property works uniformly across all platforms (glibc, musl, macOS) GRADLE_CMD="./gradlew -PCI -PkeepJFRs :ddprof-test:test${CONFIG}" if [[ -n "$TESTS" ]]; then - GRADLE_CMD="$GRADLE_CMD --tests=\"$TESTS\"" + # No need for quotes around $TESTS - Gradle property values don't require quoting + GRADLE_CMD="$GRADLE_CMD -Ptests=$TESTS" fi if ! $GTEST_ENABLED; then GRADLE_CMD="$GRADLE_CMD -Pskip-gtest" From 1f20540ae7c2962af3a85b475fe754590c633655 Mon Sep 17 00:00:00 2001 From: Jaroslav Bachorik Date: Fri, 13 Feb 2026 13:45:09 +0100 Subject: [PATCH 19/23] Use camelCase task names (testDebug) for consistency Restore original camelCase naming convention for test tasks to maintain compatibility with existing workflows.
