Last week I received a mail from a user:
Subject: "RE: Testing WTF"
Body: "please stop sending these test emails"
At first, we tried to replace all the email addresses on the database and config files, but the feature that sends the emails uses a lot of business logic. So we wanted to test the feature with a more realistic and end-to-end approach.
After looking for a while I found this lovely piece of software. MockMock is a very simple but powerful SMTP mock server built in java.
How it works:
Simply download the MockMock.jar and run java -jar MockMock.jar this starts the SMTP server on the port 25 and an HTTP server on port 8282.
Now you can configure your SMTP server as localhost on port 25, when the application sends an email just browse on http://localhost:8282/ and you'll see something like this:
And we can see de detailed info of each mail:
You can also change the ports with -p argument for SMPT and -h for HTML like java -jar MockMock.jar -p 25250 -h 8080
I love this type of test because we can extend our test cases and look for the result in a fancy and safe way.
