The need for DevOps innovation has never been greater. Get the results from over 100 business value assessments in this whitepaper, Digital Darwinism: Driving Digital Transformation, to see the positive impact of DevOps first hand.

Today, I released a new library to help developers to write integration tests with mail servers.

The library has been released on GitHub and Maven Central.

fakesmtp-junit-runner

fakesmtp-junit-runner can be found on GitHub.

Part of the source code of this library has been modified and adapted from the project of FakeSmtp. I want to thank him since his project inspired me the creation of that library.

This library is an extension to JUnit to allow developers to write integration tests where an SMTP server is required.

The how-to is quite simple:

Insert the @Rule in your integration tests.
a Fake SMTP Server will start.
You can send mail on it.
You can control the mailbox.
Write your own assertions to check mail.

Installation

The project requires JUnit 4.11 or higher. It also requires SLF4J API presents in the classpath. I did not bundle them in the library to avoid conflicts.

To use it, adds the library to your Maven or Gradle config script:

For Maven:

          < dependency > < groupId > com.github.sleroy < /groupId>          <artifactId>fakesmtp-junit-runner</artifactId > < version > 0.1 .1 < /version>          <scope>test</scope > < /dependency>

For Gradle:

          testCompile "com.github.sleroy:fakesmtp-junit-runner:0.1.1"

Usage

Step 1:

Create a JUnit test:

          public class SmtpSendingClassTest & #123;                              @Test          public void testCase1() &# 123; & #125;                    &# 125;

Step 2:

Add the new JUnit rule with its configuration:

          public class SmtpSendingClassTest &#123;                    @Rule          public FakeSmtpRule smtpServer = new FakeSmtpRule(ServerConfiguration.create().port(2525).charset("UTF-8"));                    @Test          public void testCase1() &#123;                    &#125;                    &#125;

Step 3:

You are ready to use it to control the mailbox or the server state:

          Assert.assertTrue(smtpServer.isRunning());

          public class SmtpSendingClassTest &#123;                    @Rule          public FakeSmtpRule smtpServer = new FakeSmtpRule(ServerConfiguration.create().port(2525).charset("UTF-8"));                    @Test          public void testCase1() &#123;          Assert.assertTrue(smtpServer.isRunning());          Assert.assertTrue(smtpServer.mailbox().isEmpty());          &#125;                    &#125;
