How do you unit test a mail sending function

Question

I have a function which creates a report and sends it to a user. What I\'ve done is create a mock for the email function, and verify if the \'send\' function of the email class

Answer 1

Can be done in following ways.

Step 1: Navigate to your Web.Config file and add the following tags to it.

Make sure the directory you have specified for pickup location must exist.

Step 2 : Now test your email sending functionality. I have used button_click to test this functionality with the following code.

SmtpClient smtp = new SmtpClient();
MailMessage message = new MailMessage("me@gmail.com", "me@yahoo.com","My Message Subject","This is a test message");
smtp.Send(message);

Output : It will create .eml files inside the folder with a randonly generated GUID name, which is the email that we can see after receiving it. For me it created a file like c127d1d5-255d-4a5a-873c-409e23002eef.eml in E:\MailTest\ folder

Hope this helps :)
