Mocking the UIInput Class for Tests

Question

I am trying to make fun of the javax.faces.component.UIInput class.

My class is lower

public class MyBean{ private UIInput someInput; //setters and getters } 

Test case

 UIInput mockedVale = Mockito.mock(UIInput.class); MyBean myBean = new MyBean(); myBean.setSomeInput(mockedVale); 

Can someone help me fix this

Answer 1

In the UIComponent class (which uses your test) there is a static line to initialize Logger :

 private static Logger LOGGER = Logger.getLogger("javax.faces.component", "javax.faces.LogStrings"); 

This means that the class is looking for a resource package named LogStrings in the javax.faces package. In javax.faces-2.2.11.jar there is the javax directory and subdirectory and inside it is the LogStrings.properties file. Therefore, your class is also looking for this file.

Is face-jar inside your classpath?

Answer 2

As stated in the Niklas P. answer , the cause of the problem is the initialization of Logger on the UIComponent .

To solve the problem, jsf-api-xxx.jar should be included in your project. As described here about using jsf-api-xxx.jar or javax.faces-xxx.jar (portability considerations):

You can actually use both. But the recommended way is to include jsf-api-xxx.jar only in the compilation class path.

In Maven, you just need to add the following dependency to your pom.xml :

 <dependency> <groupId>com.sun.faces</groupId> <artifactId>jsf-api</artifactId> <version>2.2.8-18</version><!-- the version you are using --> <scope>provided</scope> </dependency> 

Answer 3

I used this additional Maven dependency on the test area ( pom.xml ):

  <dependency> <groupId>javax.faces</groupId> <artifactId>javax.faces-api</artifactId> <version>2.2</version> <scope>test</scope> </dependency>
