Installing the GreenPepper Maven Plugin

 

In order to install the Maven Plugin, it is necessary to add a plugin entry to your project's pom.xml.

<plugin>
	<groupId>com.greenpepper</groupId>
	<artifactId>greenpepper-maven-plugin</artifactId>
	<version>4.0.0-SNAPSHOT</version>
	...
	<!-- further configuration here -->
</plugin>

For automatic downloads and upgrades, it is possible to add additional repositories to your project's pom.xml like this:

<repositories>
	<repository>
		<id>novatec</id>
		<url>http://nexus.novatec-gmbh.lan/content/groups/public</url>
		<snapshots>
			<enabled>true</enabled>
			<updatePolicy>never</updatePolicy>
		</snapshots>
		<releases>
			<enabled>true</enabled>
			<updatePolicy>never</updatePolicy>
		</releases>
</repositories>
 
<pluginRepositories>
	<id>novatec</id>
	<url>http://nexus.novatec-gmbh.lan/content/groups/public</url>
	<snapshots>
		<enabled>true</enabled>
		<updatePolicy>never</updatePolicy>
	</snapshots>
	<releases>
		<enabled>true</enabled>
		<updatePolicy>never</updatePolicy>
	</releases>
</pluginRepositories>

Configuring the GreenPepper Maven Plugin

Within the default Maven Build Lifecycle, there are three phases using the Maven Plugin.
 

 

In step one ("Installing the Maven Plugin") we had a look on a short block of code where it said "further configuration here". Below you find an example of how said configuration could look like.

<plugin>
	<groupId>com.greenpepper</groupId>
	<artifactId>greenpepper-maven-plugin</artifactId>
	<version><!-- your version of the GreenPepper Maven Plugin --></version>
	<configuration>
	    <source><!-- your source version --></source>
	    <target><!-- your target version --></target>
	    <fixtureSourceDirectory><!-- source directory of your fixtures, for example: src/fixture/java --></fixtureSourceDirectory>
	    <fixtureOutputDirectory><!-- output directory of the compiled fixture classes, for example: target/fixture-test-classes --></fixtureOutputDirectory>
	    <specsDirectory><!-- destination for downloaded specification files, for example: src/sprecs--></specsDirectory>
		<reportsDirectory><!-- destination for generated HTML reports, for example: target/greenpepper-reports</reportsDirectory>
		<reportsType><!-- the file format of your reports (XML or HTML, default is HTML) --></reportsType>
	    <resources>
	        <resource>
	            <directory><! -- directory for a specific resource. Example: src/fixture/resources--></directory>
	            <excludes>
	                <exclude>**/*.java</exclude>
	            </excludes>
	        </resource>
	    </resources>
	    <repositories>
	        <repository>
		        <type><!-- fully qualified name of your suit resolver class, for instance: com.greenpepper.repository.FileSystemRepository --></type>
				<root><!-- root directory of the current repository. Example: ${basedir}/src/fixture/specs --></root>
		        <suites>
		        	<suite><!-- the suit's URI --></suite>
		        </suites>
	        </repository>
	        <repository>
	            <type><!-- fully qualified name of your test resolver. --></type>
	            <tests>
	            	<test><!-- the test's URI --></test>
	            </tests>
	        </repository>
	    </repositories>
		<goalPrefix><!-- the prefix that will be associated with the plugin (optional, see below "Using the GreenPepper Maven Plugin"), eg: greenpepper --></goalPrefix>
	</configuration>
</plugin>

Using the GreenPepper Maven Plugin

Executing specification fixtures

Generally, the goals of the Maven Plugin correspond to the phases of the default Maven Build Lifecycle (with exception of the Freeze goal). Therefore, in order to interact with our fixture sources, we only have to tell Maven until which goal it should run.
NOTE: In order to use a prefix as we do below, it might be necessary to define the goalPrefix tag within the plugin configuration (see the code box above).
 

Goals

 

Now that we know which goals exist for the Maven Plugin, let's have a closer look at each of them.

greenpepper:compile 


Compiles the fixtures of an application.

Mojo attributes:

Required parameters 

NameTypeDescription
fixtureSourceDirectoryFileSource directory containing the fixture classes to be compiled.
fixtureOutputDirectoryFileOutput directory in which the compiled sources are placed.


Optional parameters

The optional parameters are exactly the same as in the Maven Compiler Plugin.
 

Parameter details

Note that the values of the expressions given below are merely default values, so their use is not mandatory. 

greenpepper:resources 


Copies resources for the main source code to the main output directory.

Mojo attributes:

Required parameters 

NameTypeDescription
resourcesListList of resources to be copied to the output directory.
fixtureOutputDirectoryFileOutput directory the resources are copied to.


Optional parameters

The optional parameters resemble those for the Maven 2 resources plugin.
 

Parameter details

Note that the values of the expressions given below are merely default values, so their use is not mandatory. 

greenpepper:run 


Executes specifications.

repositoriesRepositorysuite or test URI of specifications to test.
reportsDirectoryFileOutput directory for generated reports.
stopOnFirstFailureBooleanStops the specification's execution on the first failure if set to true.
testFailureIgnoreBooleanIgnores test failures if set to true. Although this is not recommended, there are several occasions where it might come in handy.


Optional parameters

None.
 

Parameter details

Note that the values of the expressions given below are merely default values, so their use is not mandatory. 

 

greenpepper:fixture-jar

Mojo attributes:

Required parameters 

NameTypeDescription

specsDirectoryFileDirectory the specification files are downloaded to.
repositoriesRepositorysuite or test URI of specifications to download.


Optional parameters

None.
 

Parameter details

File System Repository

In the following example, the specifications will be saved in ${basedir}/src/fixture/specs, as specified in the root element. The first repository will save its specifications in a subdirectory called Demo, the second one in a subdirectory called DemoPhoneBook.

	<repositories>	
		<repository>
    		<name>Demo</name>
        	<type>com.greenpepper.repository.FileSystemRepository</type>
            <root>${basedir}/src/fixture/specs</root>
           	<suites>
            	<suite>Demo</suite>
           	</suites>
       	</repository>
        <repository>
        	<name>DemoPhoneBook</name>
           	<type>com.greenpepper.repository.FileSystemRepository</type>
           	<root>${basedir}/src/fixture/specs</root>
            <suites>
            	<suite>DemoPhoneBook</suite>
           	</suites>
       	</repository>
	</repositories>

 

 

Command line options

 

Sonar

 

Sonar, also known as SonarQube, is an open platform that aims at managing the quality of your code. The Sonar GreenPepper Plugin feeds Sonar with the test reports provided by the GreenPepper Maven Plugin.

 

 

The easiest way to produce a Sonar report using GreenPepper test reports is the following:

mvn clean integration-test sonar:sonar

 

The integration-test will trigger the following goals:

 

Please note that in order to use the Sonar GreenPepper Plugin, the GreenPepper reports need to have XML file format which can be achieved by doing either of the following:
