我需要模拟一个从被测方法实例化的对象。请查看以下代码供您参考。
待测班级:
package org.sambaran.model;
import java.util.List;
public class Book implements Item {
private String isbn;
private String title;
private String description;
private List<Author> authors;
private BSOInterface bsoInterface;
public Book(String isbn, String title, String description,
List<Author> authors) {
super();
this.isbn = isbn;
this.title = title;
this.description = description;
this.authors = authors;
}
public String getIsbn() {
return isbn;
}
public void setIsbn(String isbn) {
this.isbn = isbn;
}
public String getTitle() {
return title;
}
public void setTitle(String title) {
this.title = title;
}
public String getDescription() {
return description;
}
public void setDescription(String description) {
this.description = description;
}
public List<Author> getAuthors() {
return authors;
}
public void setAuthors(List<Author> authors) {
this.authors = authors;
}
public void createBook(){
bsoInterface=new BSOInterfaceFactory().getBSOInterface();
bsoInterface.createBook(this);
}
}
这是测试类:
package org.sambaran.model.test;
import static org.junit.Assert.assertEquals;
import static org.junit.Assert.assertNotNull;
import static org.junit.Assert.fail;
import java.util.ArrayList;
import org.junit.After;
import org.junit.Before;
import org.junit.Test;
import org.mockito.Mock;
import org.mockito.Mockito;
import org.sambaran.model.Author;
import org.sambaran.model.BSOInterface;
import org.sambaran.model.Book;
import org.sambaran.model.Item;
public class BookTest {
@Mock
BSOInterface bsoInterface;
Item b;
@Before
public void setUp() throws Exception {
b=new Book("123-654-6789", "Head First C", "First Book on C", new ArrayList<Author>());
}
@After
public void tearDown() throws Exception {
}
@Test
public void testGetIsbn() {
assertNotNull(b.getIsbn());
}
@Test
public void testSetIsbn() {
String isbn="111-222-3333";
b.setIsbn(isbn);
assertEquals(b.getIsbn(), isbn);
}
@Test
public void testGetTitle() {
Book book=Mockito.mock(Book.class);
assertNotNull(book.getDescription());
}
@Test
public void testCreateBook(){
/**
* Here I need to mock the bsoInterface but the object is created in this method only.
*/
b.createBook();
}
@Test
public void testSetTitle() {
fail("Not yet implemented");
}
@Test
public void testGetDescription() {
fail("Not yet implemented");
}
@Test
public void testSetDescription() {
fail("Not yet implemented");
}
@Test
public void testGetAuthors() {
fail("Not yet implemented");
}
@Test
public void testSetAuthors() {
fail("Not yet implemented");
}
}
在测试createBook()期间,我需要我需要模拟的bsoInterface对象。你能告诉我怎么做吗?
答案 0 :(得分:1)
再创建一个将BSOInterfaceFactory作为参数的方法。您可以在测试中使用第二个。
public void createBook(){
create(new BSOInterfaceFactory());
}
public void create(BSOInterfaceFactory bsoInterfacefactory) {
this.bsoInterface=bsoInterfacefactory.getBSOInterface();
bsoInterface.createBook(this);
}
并且测试应该如下:
@Test
public void testCreateBook(){
BSOInterfaceFactory bsoInterfaceFactory = mock(BSOInterfaceFactory.class);
b.createBook(bsoInterfaceFactory);
}
