This sample uses a WSDL (Web Service Description Language) specification to generate tests for the todo app system under test. You can read more about the Citrus test generation features in [reference guide][4]
Objectives
The todo-list sample application manages todo entries. The application provides a SOAP Web Service API for adding new entries and listing all entries. This API is specified using a WSDL file.
The sample API specification looks like this.

The WSDL specification defines model objects as well as operations that a client can call.
Citrus is able to generate client and server side test cases from that specification. Each operation in the WSDL is the basis for a new test case. The test will use the information given in the specification to generate a proper send/receive request/response communication with the server using the SOAP operations.
The test code generation takes place in the Maven build lifecycle and uses the Citrus Maven plugin. You need to add the following plugin configuration to the Maven POM file:
<plugin>
<groupId>com.consol.citrus.mvn</groupId>
<artifactId>citrus-maven-plugin</artifactId>
<version>4.5.0</version>
<executions>
<execution>
<id>generate-tests</id>
<phase>generate-test-sources</phase>
<goals>
<goal>generate-tests</goal>
</goals>
</execution>
</executions>
<configuration>
<type>java</type>
<framework>testng</framework>
<tests>
<test>
<endpoint>todoClient</endpoint>
<disabled>true</disabled>
<wsdl>
<file>/Users/cdeppisc/Projects/Citrus/citrus-website/src/test/resources/schema/TodoList.wsdl</file>
</swagger>
</test>
</tests>
</configuration>
</plugin>
The plugin test generation binds to the generate-test-sources
Maven lifecycle phase and generates the tests in a default output directory target/generated/citrus
. The plugin needs the path to the WSDL specification file
which is usually a .wsdl
file in your project.
When executed the plugin generates the Citrus tests to the target output directory. You can add those generated files to the Maven sources/resources with another plugin called build-helper-maven-plugin
.
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>build-helper-maven-plugin</artifactId>
<version>3.0.0</version>
<executions>
<execution>
<id>add-test-sources</id>
<phase>generate-test-sources</phase>
<goals>
<goal>add-test-source</goal>
</goals>
<configuration>
<sources>
<source>/Users/cdeppisc/Projects/Citrus/citrus-website/target/generated/citrus/java</source>
</sources>
</configuration>
</execution>
<execution>
<id>add-test-resources</id>
<phase>generate-test-resources</phase>
<goals>
<goal>add-test-resource</goal>
</goals>
<configuration>
<resources>
<resource>
<directory>/Users/cdeppisc/Projects/Citrus/citrus-website/target/generated/citrus/resources</directory>
</resource>
</resources>
</configuration>
</execution>
</executions>
</plugin>
The build helper plugin adds the generated tests to the Maven project source/resource compilation. This automatically enables the generated tests for execution with the Maven build lifecycle in test/integration-test phase.
Run
