Java: Testing Web Application Pages with JWebUnit and Cargo Container

When I was a j2ee programmer, I had to develop sites with a sufficiently large number of pages, using ajax and other beautiful things for visualization. The controllers could be tested using JUnit and moq requests / responses. But for a huge number of ftl templates and their JavaScript code, this option was not suitable.



A great opportunity to test the pages for real is JWebUnit . After adding it to the project, you will have access to the WebTestCase class, which is the descendant of TestCase from the classic Junit.

The WebTestCase class provides a high-level API for working with web pages, it is simply pointless to describe it because of the beyond simplicity, so I will simply give an example of code from the main page:

public class ExampleWebTestCase extends WebTestCase {
    public void setUp () {
        super.setUp ();
        setBaseUrl (" localhost : 8080 / test");
    }
 
    public void test1 () {
        beginAt ("/ home");
        clickLink ("login");
        assertTitleEquals ("Login");
        setTextField ("username", "test");
        setTextField ("password", "test123");
        submit ();
        assertTitleEquals ("Welcome, test!");
    }
}
 

Now it would be nice to learn how to start the web server before executing the test pack,
and even better, run it on the server in a task, for example, for Ant, before assembling, and run the tests there so as not to break the production version, in case of a quick whip. Cargo Conatiner will help us with this , this Java API helps us to manage the WebServer from Java code or directly from the Ant task. By tradition, I will give both usage scenarios that can be found on the developer's site: We

execute the code with our hands

Deployable war = new WAR ("path / to / simple.war");
 
LocalConfiguration configuration =
    new Resin3xStandaloneLocalConfiguration ("target / myresin3x");
configuration.addDeployable (war);
 
InstalledLocalContainer container =
    new Resin3xInstalledLocalContainer (configuration);
container.setHome ("c: /apps/resin-3.0.18");
 
container.start ();
// Here you are assured the container is started.
 
container.stop ();
// Here you are assured the container is stopped.
 

Run in ant task ( Maven 1 , Maven 2 )

• tomcat.home - Tomato home folder
• tomcatlog.dir - Logs
• tomcatconfig.dir - The folder where the container will generate the logs
• pathtowarfile - The full path to the war file

 

  
    
    
  

 

  
  
  
  
  
  
  
 
         log = "$ {tomcatlog.dir} /cargo.log" action = "start">
