Sending the reports via mail is one of the important tasks to be mastered!

In this section, I am going to give a Java code, which will work if you just give your email address. Please note we are using gmail as sender's address as it is the widely used one.

Before proceeding with the example, please change the settings in your gmail. As we are going to trigger the mail from code, the Gmail app may consider this as a hack and it will prevent the action. So we are providing the access by changing this setting.

Here's is the link to change the google account settings.

NOTE: Once you are done with trying this, restore your setting.

The above code attaches the emailable test report in the test-output folder of my project.Run this project as a Java application and below is the snap of my inbox.

NOTE: No need to worry if you don't understand that big code. If you can use it, that is more than enough. Knowing how to drive a car is more important than wondering how the engine works. If you are capable of applying that should suffice.
