java - 有没有一种方法可以传递方法的返回值，而在引用时不会执行整个方法？

Question

在下面的代码中，您将看到 beforetest 方法返回字符串 srnumber。该变量是 beforetest 方法执行期间生成的唯一标识符。我想要做的是存储该唯一编号并在其他方法中引用它。我遇到的问题是当我做类似的事情时

public void ReferenceMethod(){
String InvoiceReference = beforetest() 
Searchfield.sendkeys(InvoiceReference)
}

由于各种原因，我不希望整个beforetest方法运行，主要原因是它创建了一个新唯一编号。

public class E2ESRInvoiceTest {
    WebDriver driver;
    Ourfsnlogin LoginPage;
    SRCreate SRCreatePage;

    HomePagePOF HomePage;
    HomePagePOFSC HomePageSC;
    Utilities UtilClass;


    @BeforeSuite
    public String beforeTest() throws InterruptedException {
        SRCreate.webdrive();
        InvoicingPOF.webdrive();
        HomePagePOFSC.webdrive();
        PageFactory.initElements(new AjaxElementLocatorFactory(Utilities.driver, 60), this);
        Utilities.driver.get("fsndevweb:81");
        SRCreatePage = PageFactory.initElements(Utilities.driver, SRCreate.class);
        LoginPage = PageFactory.initElements(Utilities.driver, Ourfsnlogin.class);
        Invoicing = PageFactory.initElements(Utilities.driver, InvoicingPOF.class);
        HomePage = PageFactory.initElements(Utilities.driver, HomePagePOF.class);
        HomePageSC = PageFactory.initElements(Utilities.driver, HomePagePOFSC.class);

        LoginPage.sendUserName("ebluth");
        LoginPage.sendPassword("password");
        LoginPage.clicksubmit();
        LoginPage.USclick();
        SRCreatePage.NavigateToSRCreatebtn();
        SRCreatePage.SRCreationTestHVAC();
        String srnumber = SRCreatePage.SRNumber.getText();
        LoginPage.Logout();
        LoginPage.sendUserNameSP("4335701");
        LoginPage.sendPassword("password");
        LoginPage.clicksubmit();
        LoginPage.SPSRSearch(srnumber);
        Thread.sleep(3000);
        Invoicing.ActivtityCompletition();
        HomePage.HomePageNaviate();
        LoginPage.SPSRSearch(srnumber);
        return srnumber;
    }

我知道这是当您引用方法返回对象时的预期行为。有办法改变吗？我真的不想在每个需要 SR 编号的方法中都包含之前测试的代码。任何帮助表示赞赏!我对 java 也很陌生，所以如果我的代码中有任何致命的罪过，我提前道歉，哈哈。

将值存储在字段中，并在每次后续调用时返回先前计算的值怎么样？

public class E2ESRInvoiceTest {
    WebDriver driver;
    Ourfsnlogin LoginPage;
    SRCreate SRCreatePage;
    InvoicingPOF Invoicing;
    HomePagePOF HomePage;
    HomePagePOFSC HomePageSC;
    Utilities UtilClass;

    private String cachedSrnumber;

    @BeforeSuite
    public String beforeTest() throws InterruptedException {
        if(cachedSrnumber != null)
            return cachedSrnumber;

        // Your beforeTest() code

        cachedSrnumber = srnumber;
        return srnumber;
    }
}
