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?
if
colcon testhas any error, you can check the result withcolcon test-result --verboseand 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 toFinished <<< launch_testing_examples [18.0s].
