java - Liferay 中的 JUnit 和模拟

Question

我需要使用 Mockito 或 PowerMock 或其他工具进行 JUnit 测试，但我不知道从什么开始。我创建了测试文件夹，设置了 mockito，但接下来我应该做什么？我找不到任何示例，所以我坚持使用它。你能告诉我如何编写这个 JUnit 测试或者至少给出一些想法吗。

public void deleteAuthor(ActionRequest actionRequest, ActionResponse actionResponse)
        throws SystemException, PortalException {
    long authorId = ParamUtil.getLong(actionRequest, "authorId");
    AuthorLocalServiceUtil.deleteAuthor(authorId);
    SessionMessages.add(actionRequest, "deleted-author");
    log.info(DELETE_SUCCESS);

}

或者这个:

public void addAuthor(ActionRequest actionRequest, ActionResponse actionResponse) 
        throws IOException, PortletException, SystemException {

    String authorName=ParamUtil.getString(actionRequest,"authorName");
    Author author=AuthorLocalServiceUtil.createAuthor(CounterLocalServiceUtil.increment());
    author.setAuthorName(authorName);
    author=AuthorLocalServiceUtil.addAuthor(author);        
}

附言我是新手，一生中只做过 1 次 JUnit 测试，所以我真的很想听听好的建议。提前致谢!

更新:

我尝试这样做:

private BookAndAuthor portlet;

@Before
public void setUp() {
    portlet = new BookAndAuthor();
}


@Test
public void testDeleteBookOk() throws Exception {
    PowerMockito.mockStatic(BookLocalServiceUtil.class);
    long id = 1;
    Book book = BookLocalServiceUtil.createBook(id);

    ActionRequest actionRequest = mock(ActionRequest.class);
    ActionResponse actionResponse = mock(ActionResponse.class);

    when(BookLocalServiceUtil.deleteBook(book)).thenReturn(null);
    Book result = BookLocalServiceUtil.deleteBook(book);
    assertEquals(result, null);
}

...但没有成功。

我们正在使用以下设置运行 JUnit 测试:

i. 在您的 portlet 中的 docroot 旁边创建 test 文件夹。

ii. 添加 unit 文件夹以在其中测试和创建您的 package。

iii. 使用以下配置在您的 test 文件夹中创建 portal-ext.properties 文件:

jdbc.default.driverClassName=com.mysql.jdbc.Driver
jdbc.default.url=jdbc:mysql://localhost:3309/db_name?useUnicode=true&characterEncoding=UTF-8&useFastDateParsing=false
jdbc.default.username=your_username
jdbc.default.password=your_password

jdbc.default.automaticTestTable=C3P0TestTable
jdbc.default.idleConnectionTestPeriod=36000
jdbc.default.maxIdleTime=1200

iv. 创建一个套件类(比如 AbcSuite.java)如下:

package x.x.x;

import org.junit.AfterClass;
import org.junit.BeforeClass;
import org.junit.runner.RunWith;
import org.junit.runners.Suite;

import com.liferay.portal.util.InitUtil;

@RunWith(Suite.class)
@Suite.SuiteClasses({
    // Where AxTest.class would be your test class name
    A1Test.class, A2Test.class, AxTest.class
})

public class AbcSuite {

    @BeforeClass
    public static void setUp() throws Exception {
        // Loading properties and establishing connection with database
        InitUtil.initWithSpring();
        System.out.println("X Portlet's Test Suite Execution : Started.");
    }

    @AfterClass
    public static void tearDown() {
        System.out.println("X Portlet's Test Suite Execution : Completed.");
    }
}

v. 创建一个测试类(比如 A1Test.java)如下:

package x.x.x;

import java.util.ArrayList;

import org.junit.Assert;
import org.junit.BeforeClass;
import org.junit.Test;

public class A1Test {

    @BeforeClass
    public static void setUp() throws Exception {
        System.out.println("Test Running : A1Test");
    }

    @Test
    public void testAddAuthor() {
        Author author = AuthorLocalServiceUtil.createAuthor(
            CounterLocalServiceUtil.increment());
        author.setAuthorName("Testcase Author");
        author = AuthorLocalServiceUtil.addAuthor(author);

        Assert.assertNotNull(author);
        Assert.assertTrue(author.getAuthorId() > 0);
    }
}

就是它!您可以使用以下命令一起执行所有测试用例:

ant test -Dtest.class=AbcSuite*

或单独作为:

ant test -Dtest.class=A1Test*
