Integration Test

Integration Test

Not all tests run at a fast speed, as some of the tests are very complex with external dependencies. It will take more time to run all tests so it is better to separate unit tests and integration tests.

In this case, in the normal package, only unit tests will be executed so that can be done really fast.

On a daily basis, we might run nightly builds to include both unit tests and integration tests together.

Integration tests

Normally, the integration test will require that there are some servers running such as database, webserver etc. Some test cases need to be repeated many times. These tests will be located in src/integration folder and all test classes will end with “IT”.

As integration is not the default test source folder or resources folder, we need to add this in pom.xml

            <plugin>
                <groupId>org.codehaus.mojo</groupId>
                <artifactId>build-helper-maven-plugin</artifactId>

                        <configuration>
                            <sources>
                                <source>${project.basedir}\src\integration\java</source>
                            </sources>

                                    <directory>${project.basedir}\src\integration\resources</directory>
                                </resource>
                            </resources>
                        </configuration>

                </executions>
            </plugin>

Maven failsafe plugin

The integration tests will be called from maven failsafe plugin.

            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-failsafe-plugin</artifactId>
                <version>2.19.1</version>
                <configuration>
                    <encoding>UTF-8</encoding>
                </configuration>
                <executions>
                    <execution>
                        <id>integration-test</id>
                        <goals>
                            <goal>integration-test</goal>
                            <goal>verify</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>
