Java 如何在@Before注释下调用方法

Java 如何在@Before注释下调用方法,java,exception,selenium,junit,automated-tests,Java,Exception,Selenium,Junit,Automated Tests,在@Before junit注释下从另一个类调用方法时遇到问题 类别1: public class welcomePageTests extends SystemLogin { @Page system system; protected TestHarness getTestHarness() { return TestHarness.getInstance(); } private static final org.slf4j.L

在@Before junit注释下从另一个类调用方法时遇到问题

类别1:

public class welcomePageTests extends SystemLogin {
    @Page
    system system;
    protected TestHarness getTestHarness() {
    return TestHarness.getInstance();        }
        private static final org.slf4j.Logger LOGGER = LoggerFactory.getLogger(welcomePageTests.class);

    @Before
    loggingToSystem();

    @Test
    public void shouldVerifyPageLayoutAfterFirstRunAndLayoutConsistency() throws Exception {
    clickOnByLocator(welcome.homeButton);
    assertThatIsDisplayedByLocator(welcome.usersButton);
    mainPageLayout.assertMainPageElements(welcome);
    clickOnByLocator(welcome.usersButton);
    mainPageLayout.assertMainPageElements(welcome);
    clickOnByLocator(welcome.loginButton);
    mainPageLayout.assertMainPageElements(welcome);
}
类别2:

public class SystemLogin extends HelperMethods {
    protected TestHarness getTestHarness() {
        return TestHarness.getInstance();
    }
    @Page
    system system;

        public void loggingToSystem() throws InterruptedException {
        goTo(PageRunner.class);
        getDriver().manage().window().maximize();
        Thread.sleep(2000);
        system.userLogin.text("mr");
        system.password.text("password");
        system.signInbutton.click();
    }
}
问题是我不能在@Before注释下直接调用loggingToSystem方法(而在@Test注释下则可以)

获取无效的方法声明错误

像那样努力:

@Before
public void loggingToSystem() {return loggingToSystem();}
但在这种情况下,获取的错误不能从具有void结果类型的方法返回值


有人知道问题的原因并能给我现成的解决方案吗?

什么是
loggingToPanda()
返回类型

返回类型为
void
的方法意味着它不会返回任何东西。如果
loggingToPanda()
方法也有
void
返回类型,则更改代码如下:

@Before
public void loggingToPanda() {
                loggingToPanda();
}

一秒钟后,我意识到我犯了一个错误:) 这就是解决方案:

@Before
public void setup() throws InterruptedException {
    loggingToPanda();
}
