+You can send test email in several ways:
+First of all, you should set application.properties properly.
+1. Just build the project and the test email for order confirmation will be sent on Spring Boot Start.
+2. You can use the web form and test all the cases of sending email in your browser.
+Just start the application then type http://localhost:8080 and follow the web flow.
+You can send simple email, email with template, email with attachment from the web.
