java - 如何使用 POM Selenium 从下拉列表中进行选择

Question

所以我需要从下拉列表中进行选择，所有代码似乎只是突出显示值而不是选择它，

package uk.co.brightfuture.bfslogin.selenium.page;

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.support.FindBy;
import org.openqa.selenium.support.PageFactory;
import org.openqa.selenium.support.ui.Select;

import uk.co.brightfuture.bfslogin.selenium.PagePath;
import uk.co.brightfuture.bfslogin.selenium.PageTitle;

public class CreateNewUserPage extends Page {

@FindBy(name = "firstname")
private WebElement firstNameTextBox;

@FindBy(name = "surname")
private WebElement surnameTextBox;

@FindBy(name = "phonenumber")
private WebElement phonenumberTextBox;

@FindBy(name = "username")
private WebElement userNameTextBox;

@FindBy(name = "password")
private WebElement passwordTextBox;

@FindBy(name = "next of kin firstname")
private WebElement nextOfKinFirstnameTextBox;

@FindBy(name = "next of kin surname")
private WebElement nextOfKinSurnameTextBox;

@FindBy(name = "next of kin phonenumber")
private WebElement nextOfKinPhonenumberTextBox;

@FindBy(name = "dropdown2")
private WebElement authorityDropdown;

@FindBy(name = "Admin")
private WebElement adminFromDropdown;

@FindBy(name = "User")
private WebElement userFromDropdown;

@FindBy(name = "Fire")
private WebElement fireMarshallFromDropdown;

@FindBy(name = "dropdown")
private WebElement groupDropdown;

@FindBy(name = "group")
private WebElement groupFromDropdown;

@FindBy(name = "add")
private WebElement addButton;

public CreateNewUserPage(WebDriver driver) {
    super(driver, PageTitle.CREATEUSER, PagePath.CREATEUSER);

    // COMPULSORY
    this.driver = driver;
    PageFactory.initElements(driver, this);

}

public void enterFirstName(String firstNameText) {
    firstNameTextBox.sendKeys(firstNameText);
}

public void enterSurName(String surnameNameText) {
    surnameTextBox.sendKeys(surnameNameText);
}

public void enterPhonenumber(String phonenumberText) {
    phonenumberTextBox.sendKeys(phonenumberText);
}

public void enteruserName(String userNameText) {
    userNameTextBox.sendKeys(userNameText);
}

public void enterpassword(String passwordText) {
    passwordTextBox.sendKeys(passwordText);
}

public void enternextOfKinFirstname(String nextOfKinFirstNameText) {
    nextOfKinFirstnameTextBox.sendKeys(nextOfKinFirstNameText);
}

public void enternextOfKinSurname(String nextOfKinSurnameText) {
    nextOfKinSurnameTextBox.sendKeys(nextOfKinSurnameText);
}

public void enternextOfKinPhonenumber(String nextOfKinPhonenumberText) {
    nextOfKinPhonenumberTextBox.sendKeys(nextOfKinPhonenumberText);
}

public void AuthorityDropDown() {
    authorityDropdown.click();
}

public  void adminViaDropDown() {
      Select drop = new Select(authorityDropdown);
      drop.selectByIndex(1);  
}

public void userFromDropdown() {
    userFromDropdown.click();
}

public void userFromDropDown() {
    fireMarshallFromDropdown.click();
}

public void GroupDropDown() {
    groupDropdown.click();
}

public Boolean getGroupDropown(String textToCheck) {
    return groupFromDropdown.getText().equals(textToCheck);
}

public NewUserConfirmationPage AddUserButton() {
    addButton.click();
    return new NewUserConfirmationPage(driver);
}

这是我要运行的测试，

    /**
 * this test will go to the new create new user page via the dash board and
 * it will enter the required data into the text fields.
 */

@Test
public void createNewUserWithCorrectData() {
    createNewUserPage = dashboardPage.clickCreateNewUserLink();
    assertTrue(isOnThisPage(PagePath.CREATEUSER));
    createNewUserPage.enterFirstName(FIRST_NAME);
    createNewUserPage.enterSurName(SURNAME);
    createNewUserPage.enterPhonenumber(PHONE_NUMBER);
    createNewUserPage.enteruserName(EMAIL);
    createNewUserPage.enterpassword(PASSWORD);
    createNewUserPage.enternextOfKinFirstname(NEXT_OF_KIN_FIRST_NAME);
    createNewUserPage.enternextOfKinSurname(NEXT_OF_KIN_SURNAME);
    createNewUserPage.enternextOfKinPhonenumber(NEXT_OF_KIN_PHONE_NUMBER);

    JavascriptExecutor jse = (JavascriptExecutor)driver;
    jse.executeScript("window.scrollBy(0,250)", "");

    createNewUserPage.AuthorityDropDown();
    createNewUserPage.adminViaDropDown();
    createNewUserPage.GroupDropDown();
    createNewUserPage.getGroupDropown(GROUP);
    newUserConfirmationPage = createNewUserPage.AddUserButton();
    assertTrue(isOnThisPage(PagePath.CREATECONFIRMED));
}

但是我只能使用页面对象模型，因为我的经理不允许我们使用其他任何东西。

<body>
<div class="back">
    <div id="different">
        <form method="post">
            <div class="center">

                placeholder="Next of kin firstname"> <input type="string"
                class="form-control" name="next of kin surname"
                placeholder="Next of kin surname"> <input type="number"
                class="form-control" name="next of kin phonenumber"

这是 HTML

Answer 1

你需要给我们stacktrace和

public  void adminViaDropDown() {
      Select drop = new Select(authorityDropdown);
      drop.selectByIndex(1);  
}

只选择第一个索引的下拉列表

你应该做的

public  void adminViaDropDown(int index) {
      Select drop = new Select(authorityDropdown);
      drop.selectByIndex(index);  
}

使用:

createNewUserPage.adminViaDropDown(1);

关于如何选择下拉列表，您还有多个选项。参见 this

但是，如果动态加载元素，有时元素映射技术无法按预期工作。在那种情况下，我会实时找到元素。

public  void adminViaDropDown(int index) {
      WebEelement ele = driver.findElement("your by selector")
      Select drop = new Select(ele );
      drop.selectByIndex(index);  
}

而且，另一种可能性是等待。如果没有任何效果，我会在最后插入它。这是显式等待

public  void adminViaDropDown(int index) {
          WebElement myDynamicElement = (new WebDriverWait(driver, 10))
  .until(ExpectedConditions.presenceOfElementLocated(By.id("myDynamicElement")));  
          Select drop = new Select(myDynamicElement );
          drop.selectByIndex(index);  
    }

编辑:直接使用css

找到选项

//css
public  void adminViaDropDownByName() {
    By byCss = By.cssSelector("#dropdown2>option[name='admin']");
    driver.findElement(byCss).click();      
}

第二次编辑我不喜欢这里的 HTML 设计。你应该和开发商谈谈。但是，我发现了一个非常糟糕的方法来处理这个问题。我不建议这样做。但只是一种解决方法。

JavascriptExecutor js = (JavascriptExecutor) driver;
js.executeScript("document.getElementById('dropdown2').querySelector('[name=admin]').setAttribute('selected','selected');");
