Now I'm sharing the java listener for generating the HTML report with test results. After you add this listener to your java project, you need to add it to your xml runner file like this: <listeners> <listener class-name="automationInfra.com.listeners.CustomizedEmailableReport"> </listener> </listeners> Now we back to Jenkins pipeline send email stage, in y...
