Functional Testing with Cargo
This page explains how to do functional testing with the Cargo Java API and JUnit.Are you using ANT or Maven2/Maven3?
If you are relying on ANT or Maven2/Maven3 for your build, it is probably easier for you to use the associated tasks/plugin directly:
- The documentation for the CARGO ANT tasks can be found here: Ant support.
- The documentation for the CARGO Maven2/Maven3 plugin can be found here: Maven2 plugin.
Note that the Maven2/Maven3 plugin also has archetypes you can directly use as a skeleton for integration.
Example
The best is to create a JUnit TestSetup extension so that you start and stop your container once for the whole test suite. For example:
import junit.extensions.TestSetup;
import junit.framework.Test;
[...]
public class CargoTestSetup extends TestSetup
{
InstalledLocalContainer container;
public CargoTestSetup(Test test)
{
super(test);
}
protected void setUp() throws Exception
{
// (1) Optional step to install the container from a URL pointing to its distribution
Installer installer = new ZipURLInstaller(
new URL("http://repo1.maven.org/maven2/org/apache/tomcat/tomcat/7.0.68/tomcat-7.0.68.zip"));
installer.install();
// (2) Create the Cargo Container instance wrapping our physical container
LocalConfiguration configuration = (LocalConfiguration) new DefaultConfigurationFactory().createConfiguration(
"tomcat7x", ContainerType.INSTALLED, ConfigurationType.STANDALONE);
InstalledLocalContainer container =
(InstalledLocalContainer) new DefaultContainerFactory().createContainer(
"tomcat7x", ContainerType.INSTALLED, configuration);
container.setHome(installer.getHome());
// (3) Statically deploy some WAR (optional)
configuration.addDeployable(new WAR("cargo.war"));
// (4) Start the container
container.start();
}
protected void tearDown() throws Exception
{
// (6) Stop the container
container.stop();
}
}
Then write your test case. For example:
import junit.framework.TestCase;
import junit.framework.Test;
import junit.framework.TestSuite;
[...]
public class MyTest extends TestCase
{
public static Test suite()
{
TestSuite suite = new TestSuite(MyTest.class);
return new CargoTestSetup(suite);
}
public void testSomething()
{
// (5) Perform any test you wish here
[...]
}
}
