To use the Struts 2 JUnit plugin, you'll need to have the plugin's Jar file on your application's class path. If you're using Maven you can add this dependency to your pom.xml.
| Code Block | ||||||
|---|---|---|---|---|---|---|
| ||||||
<dependency>
<groupId>org.apache.struts</groupId>
<artifactId>struts2-junit-plugin</artifactId>
<version>STRUTS_VERSION</version>
</dependency>
|
...
For this tutorial we'll use the following Struts 2 ActionSupport class.
| Code Block | ||||||
|---|---|---|---|---|---|---|
| ||||||
public class AccountAction extends ActionSupport {
private static final long serialVersionUID = 1L;
private static final Logger logger = Logger.getLogger( AccountAction.class.getName() );
private Account accountBean;
public String execute(){
return SUCCESS;
}
public void validate(){
logger.debug("In method validate. accountBean's state is " + accountBean );
if ( accountBean.getUserName().length() == 0 ){
addFieldError( "accountBean.userName", "User name is required." );
}
if ( accountBean.getUserName().length() < 5 ) {
addFieldError( "accountBean.userName", "User name must be at least 5 characters long." );
}
if ( accountBean.getUserName().length() > 10 ) {
addFieldError( "accountBean.userName", "User name cannot be at more than 10 characters long." );
}
}
public Account getAccountBean() {
return accountBean;
}
public void setAccountBean(Account accountBean) {
this.accountBean = accountBean;
}
}
|
...
To test the validate method we can use the Struts 2 JUnit plugin to simulate the Servlet container and Struts 2 framework. Our Junit test class just needs to extend the StrutsTestCase. The StrutsTestCase class is part of the Strut 2 JUnit Plugin library.
| Code Block | ||||||
|---|---|---|---|---|---|---|
| ||||||
public class TestAccountActionUsingStrutsTestCase extends StrutsTestCase {
public void testUserNameErrorMessage() throws Exception {
request.setParameter("accountBean.userName", "Bruc");
request.setParameter("accountBean.password", "test");
ActionProxy proxy = getActionProxy("/createaccount");
AccountAction accountAction = (AccountAction) proxy.getAction();
proxy.execute();
assertTrue("Problem There were no errors present in fieldErrors but there should have been one error present", accountAction.getFieldErrors().size() == 1);
assertTrue("Problem field account.userName not present in fieldErrors but it should have been",
accountAction.getFieldErrors().containsKey("accountBean.userName") );
}
public void testUserNameCorrect() throws Exception {
request.setParameter("accountBean.userName", "Bruce");
request.setParameter("accountBean.password", "test");
ActionProxy proxy = getActionProxy("/createaccount");
AccountAction accountAction = (AccountAction) proxy.getAction();
String result = proxy.execute();
assertTrue("Problem There were errors present in fieldErrors but there should not have been any errors present", accountAction.getFieldErrors().size() == 0);
assertEquals("Result returned form executing the action was not success but it should have been.", "success", result);
}
}
|
...
We then create a proxy of the createaccount action. This action is defined in struts.xml as follows.
| Code Block | ||||||
|---|---|---|---|---|---|---|
| ||||||
<action name="createaccount" class="edu.ku.it.si.struts2_junit_example.action.AccountAction"> <result>/thankyou.jsp</result> <result name="input">/createaccount.jsp</result> </action> |
...
Override getConfigPath method to return a comma separated list of paths to a configuration file.
| Code Block | ||||||
|---|---|---|---|---|---|---|
| ||||||
@Override
protected String getConfigPath() {
return "struts-test.xml";
}
|
...
protected java.lang.String getContextLocations()
For example:
| Code Block | ||||||
|---|---|---|---|---|---|---|
| ||||||
@Override
public String getContextLocations() {
return "edu/ku/it/si/tutorial/action/TestAccountAction-context.xml";
}
