使用switch语句返回不同的页面实例

Question

我对Java有点陌生，正在将它与硒一起使用。我有一个通用的页面对象类，该类具有执行相同任务的不同方法，但是根据到达的方式返回不同的页面（即，调用哪种方法）。所以我想做的是创建一个带有switch语句的方法，该方法将返回不同的页面实例。

由于页面上的标题文本将反映前往共享页面的过程，所以我想我可以使用INVOICE_HEADER_IDENTIFIER作为切换值吗？在这种情况下，只是寻找一些指导和最佳实践。

public AccomodationInvoiceDetails searchForStudentAccomodationInvoice(String studentNo){
    assertThat(getTextFromElement(INVOICE_HEADER_IDENTIFIER).equals("Create Accommodation Invoice : Select Invoice")).isTrue();
    enterTextIntoElement(SELECT_STUDENT_FIELD_IDENTIFIER, "1990514");
    clickElement(NEXT_BUTTON_IDENTIFIER);
    waitForElementToBeDisplayed(By.id("ANSWER.TTQ.MENSYS.1."), driver, 10);
    return new AccomodationInvoiceDetails(driver);
}

public CreditNoteSelectInvoicePage searchForStudentAccomodationCreditNote(String studentNo){
    assertThat(getTextFromElement(INVOICE_HEADER_IDENTIFIER).equals("Create Accommodation Credit Note : Select Student")).isTrue();
    enterTextIntoElement(SELECT_STUDENT_FIELD_IDENTIFIER, "1990514");
    clickElement(NEXT_BUTTON_IDENTIFIER);
    waitForElementToBeDisplayed(By.id("ANSWER.TTQ.MENSYS.1."), driver, 10);
    return new CreditNoteSelectInvoicePage(driver);
}

Answer 1

您可以尝试这个：

public Object searchForStudentAccomodation(String studentNo){
        String invoiceHeader = getTextFromElement(INVOICE_HEADER_IDENTIFIER);
        switch (invoiceHeader){
            case "Create Accommodation Credit Note : Select Student" :
                commonInvoiceAction(studentNo);
                return new CreditNoteSelectInvoicePage(driver); 

            case "Create Accommodation Invoice : Select Invoice" :
                commonInvoiceAction(studentNo);
                return new AccomodationInvoiceDetails(driver);

            default :
                System.out.println("Invalid invoice header : "+invoiceHeader);
                return  null;

        }
    }

    public void commonInvoiceAction(String studentNo){
        enterTextIntoElement(SELECT_STUDENT_FIELD_IDENTIFIER, studentNo);
        clickElement(NEXT_BUTTON_IDENTIFIER);
        waitForElementToBeDisplayed(By.id("ANSWER.TTQ.MENSYS.1."), driver, 10);
    }
