根因分析

ROS2包中的一个或多个测试用例返回非零退出状态，通常由断言失败、缺少依赖或测试执行期间的运行时异常导致。

English

One or more test cases in the ROS2 package returned non-zero exit status, often due to assertion failures, missing dependencies, or runtime exceptions during test execution.

解决方案

  1. Run colcon test with --event-handlers console_direct+ to see detailed test output and identify failing tests.
  2. Check test log files in 'log/test_*' directory for specific failure messages.
  3. Update test dependencies in package.xml and run 'rosdep install -i --from-paths src' to ensure all test packages are installed.

无效尝试

常见但无效的做法:

  1. Re-running colcon test without cleaning build artifacts 40% 失败

    Stale test binaries or cached results may mask underlying failures; a clean rebuild is needed.

  2. Disabling all tests with --packages-select and --mixin skip-tests 80% 失败

    This bypasses the problem without fixing it, leaving broken tests for later.

  3. Upgrading colcon-core to latest version 30% 失败

    The error is test-logic related, not a colcon tool bug.
