@ARIHANTJAIN456 Code_Sniffer is the linting package for the php and we are following some ruleset for the linting that is defined in the project and we have integrated this linting check to the Travis which checks for the build. As you can find in the Travis log that build is failed due to code_sniffer errors so you need to fix that by fixing all the linting errors in the project.
