如何使用PowerMock测试方法Jsoup.connect(静态)? [英] How to test method Jsoup.connect (static) using PowerMock?

问题描述

这是我的代码:

public void analyze(String url) throws SiteBusinessException {
        Document doc = null;
        Response response = null;
        try {
            response = Jsoup.connect(url).execute();
            doc = Jsoup.connect(url).get();
        } catch (IOException e) {
            LOGGER.warn("Cannot analyze site [url={}, statusCode={}, statusMessage={} ]", new Object[] {url, response.statusCode(), response.statusMessage()});
            throw new SiteBusinessException(response.statusMessage(), String.valueOf(response.statusCode()));
        }
    }

如何使用PowerMock测试此方法?我想编写测试以检查在调用.execute()时是否抛出IOException并捕获并随后抛出SiteBusinessException.

How can I test this method using PowerMock? I want to write test to check that when invoke .execute() then throw IOException and it catch then throw SiteBusinessException.

我的测试代码.

@RunWith(PowerMockRunner.class)
@PrepareForTest({Jsoup.class})

Test(expected = SiteBusinessException.class)
    public void shouldThrowIOException() throws Exception {
        Connection connection = PowerMockito.mock(Connection.class);

    Response response = PowerMockito.mock(Response.class);

    PowerMockito.when(connection.execute()).thenReturn(response);

    PowerMockito.mockStatic(Jsoup.class);

    expect(Jsoup.connect(SITE_URL)).andReturn(connection);

    replay(Jsoup.class);

    PowerMockito.when(Jsoup.connect(SITE_URL).execute()).thenThrow(new IOException());

    AnalyzerService sut = new AnalyzerServiceImpl();
    sut.analyzeSite(SITE_URL);

    }

我知道了

java.lang.Exception: Unexpected exception, expected<com.siteraport.exception.SiteBusinessException> but was<java.lang.IllegalStateException>

??

推荐答案

您需要创建Jsoup类的静态模拟.一旦在测试用例中创建了这样的模拟，就可以使用它来编写期望值.

You need to create a static mock of the Jsoup class. Once you have created such a mock in your test case, you can code your expectations using it.

请参阅使用PowerMockito模拟静态方法文档.

在这里使用Mockito和PowerMockito测试用例:

Here the Testcase using Mockito and PowerMockito:

我能够使用Mockito + Powermockito模拟执行方法(您同时使用EasyMock和Mockito吗?)测试用例中的代码如下:

I was able to mock the execute method using Mockito + Powermockito (you are using both EasyMock and Mockito?) The code in the test case looks as below:

@RunWith(PowerMockRunner.class)
@PrepareForTest({Jsoup.class})
public class MyClassTest {

    @Test(expected = SiteBusinessException.class)
    public void shouldThrowIOException() throws Exception {
        String SITE_URL = "some_url_string";

        Connection connection = Mockito.mock(Connection.class);
        Mockito.when(connection.execute()).thenThrow(new IOException("test"));
        PowerMockito.mockStatic(Jsoup.class);

        PowerMockito.when(Jsoup.connect(Mockito.anyString())).
            thenReturn(connection);

        AnalyzerService sut = new AnalyzerService();
        sut.analyze(SITE_URL);
    }
}
