I present you, how to write a S3 Java Sample program that is using a mock S3 server to develop the functionalities.

This article is a presentation of a new little framework, I have developed and used on several projects.

The framework is for Spring Framework and requires Java 8.0. The code is on GitHub and downloadable from Bintray or JCenter.

This is a simple example of code to demonstrate how to use the library fakesmtp-junit-runner to write integration tests with mail servers.

The library has been released on GitHub and Maven Central. (more…)

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

Build Status

Coverage Status

Links : github.

Important : 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 a SMTP server is required.

The how-to is quite simple :

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

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 :

Creates a JUnit test :

public class SmtpSendingClassTest {


  @Test
  public void testCase1() {

  }

}

Step 2 :

Adds the new Junit rule with its configuration :

public class SmtpSendingClassTest {

  @Rule
    public FakeSmtpRule smtpServer = new FakeSmtpRule(ServerConfiguration.create().port(2525).charset("UTF-8"));

  @Test
  public void testCase1() {

  }

}

Step 3 :

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

Assert.assertTrue(smtpServer.isRunning());
public class SmtpSendingClassTest {

  @Rule
    public FakeSmtpRule smtpServer = new FakeSmtpRule(ServerConfiguration.create().port(2525).charset("UTF-8"));

  @Test
  public void testCase1() {
    Assert.assertTrue(smtpServer.isRunning());
    Assert.assertTrue(smtpServer.mailbox().isEmpty());
  }

}
