What can I do to solve this problem? Thank you.
Do I need to remove the folder "launch_testing_examples" ? Because in the documentation this folder do not exist.
@leizhenyu-lzy can you provide the complete procedure from the beginning instead of posting the images?
but have problem in running colcon test
if colcon test has any error, you can check the result with colcon test-result --verbose and the fix the failures.

if you are following the examples, i do not think you need to remove them because those are the packages in examples. e.g https://github.com/ros2/examples/tree/rolling/rclpy/executors/examples_rclpy_executors
"stderr output" doesn't mean that there were test failures: it simply means that some tests printed things to stderr, which could just be deprecation warnings.
If tests had failed, colcon would've printed [ with test failures ] next to Finished <<< launch_testing_examples [18.0s].
