Hello, consult module file override path

Hello,
I have modified the helper.php and mod_easybloglatestblogs.xml files in the easyblog module (modules/mod_easyblogtopblogs)

I need to overwrite the original file，I tried to override the module template file

PATH_TO_JOOMLA/modules/mod_easyblogtopblogs/helper.php
to
TEMPLATE_NAME/html/mod_easyblogtopblogs/helper.php

PATH_TO_JOOMLA/modules/mod_easyblogtopblogs/mod_easyblogtopblogs.xml
to
TEMPLATE_NAME/html/mod_easyblogtopblogs/mod_easyblogtopblogs.xml

The results of coverage failed, Why？How do I implement coverage.
