as you can see the wrong PHPCS class is used from /usr/share/php/PHP/CodeSniffer instead of from your composer folder at /home/lenovo/.composer/vendor.

Please uninstall PHP CodeSniffer from /usr/share/php/PHP and try again.

The module name currently isn't one of the keys that's being validated on Drupal 8 projects. Could you add the following to your *.info.yml file and check again using phpcs --standard=DrupalPractice --extensions=yml /path/to/drupal/example_module

dependencies:
  - system

This should display the following output:

FILE: foo.info.yml
----------------------------------------------------------------------------------------------------------
FOUND 0 ERRORS AND 1 WARNING AFFECTING 1 LINE
----------------------------------------------------------------------------------------------------------
 8 | WARNING | All dependencies must be prefixed with the project name, for example "drupal:"

mymodule.info.yml file code is below
type: module
description: 'XXXXXXXXXXXXXXXxx.'
package: XXXXXXXXXXXX API
core: 8.x

And I ran "phpcs --standard=DrupalPractice --extensions=yml /path/to/drupal/mumodule/mymodule.info.yml"

Nothing is showing

The module name currently isn't one of the keys that's being validated, which means your given info file is valid according to the DrupalPractice standard. Could you change your info file to following and check again:

type: module
description: 'XXXXXXXXXXXXXXXxx.'
package: XXXXXXXXXXXX API
core: 8.x

dependencies:
  - system

@Arkener
Ok, thanks for "*.info.yml"

What about other YML files like "*libraries.yml", "*.links.menu.yml", "*.services.yml", and "*.routing.yml" etc.

All YAML files in the given directory will be scanned if you pass the yml extension phpcs --standard=DrupalPractice --extensions=yml /path/to/drupal/mymodule. This includes the libraries, menu, services and routing files. The scanned files can be displayed using the verbose option, for example phpcs --standard=DrupalPractice --extensions=php,module,inc,install,test,profile,theme,css,info,txt,md,yml /path/to/drupal/example_module -v
