public class MyXML {
private MessageParser messageParser;
private String valueA;
private String valueB;
private String valueC;
public MyXML (MessageParser messageParser) {
this.messageParser=messageParser;
}
public void build() {
try {
setValueA();
setValueB();
setValueC();
} catch (Exception e) {
e.printStackTrace();
}
}
private void setValueA() {
valueA = messageParser.getArrtibuteUsingXPath("SomeXPath1...");
}
private void setValueB() {
valueB = messageParser.getArrtibuteUsingXPath("SomeXPath2...");
}
private void setValueC() {
valueC = messageParser.getArrtibuteUsingXPath("SomeXPath...");

public String getValueA() {

public String getValueB() {

public String getValueC() {

}
}
So I need to use Mockito to test the builder method. Im fairly new to Mockito could someone give me some example code as to how I might write a test for the builder method?
If you want to suggest any ways I might change the design of the class or make it easier to test let me know.
To test build() you can try :
@RunWith(MockitoJUnitRunner.class)
public class YourTest {
@Mock
private private MessageParser messageParserMock;
// this one you need to test
private MyXML myXML;
@Test
public void test() {
myXML = new MyXML(messageParserMock);
// I believe something like this should work
Mockito.doAnswer(/* check mockito Answer to figure out how */)
.when(messageParserMock).getArrtibuteUsingXPath(anyString());
// you should do this for all your 3 getArrtibuteUsingXPath because setValueA(), setValueB(), setValueC() are called that one and then call build and verify results
myXML.build(); // for instance
assertEquals("something you return as Answer", myXML.getValueA());
}
}
The resource https://static.javadoc.io/org.mockito/mockito-core/2.8.9/org/mockito/Mockito.html#stubbing_with_exceptions might be useful - it describes how to stub void methods call.
