I want to add a text to logs for debug. i tried to use "logger.debug("qwerty exam log");" and "logger.info("qwerty exam log");" in JavaScript action but i can see them in Logs
You need to check the Javascript logging level in your NeoLoad preferences so it can match your logger level.
For instance, go to menu "Edit-->Preferences-->Project settings tab --> Runtime parameters.
If you use "logger.debug" you need to select "DEBUG" from the drop down list.
