How to select the auto suggestion from the dynamic dropdown using Selenium and Java

问题

I am trying to select the value for Subjects field in the following form: https://demoqa.com/automation-practice-form

It is an input field that dynamically gives suggestions based on our input and later we need to select values from those suggestions. I am unable to select the desired value.

The Below code only populates the input area but the value is not selected.

driver.findElement(By.id("subjectsInput")).sendKeys("English");

driver.findElement(By.id("subjectsInput")).click(); //This line doesnot click on the desired value.

How to Select the desired value. Please help.

To invoke click on the only auto suggestion English you need to induce WebDriverWait for the elementToBeClickable() and you can use either of the following Locator Strategies:

• cssSelector:

  driver.get("https://demoqa.com/automation-practice-form");
  new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(By.cssSelector("input#subjectsInput"))).sendKeys("English");
  new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(By.cssSelector("div.subjects-auto-complete__menu"))).click();
  

• xpath:

  driver.get("https://demoqa.com/automation-practice-form");
  new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(By.xpath("//input[@id='subjectsInput']"))).sendKeys("English");
  new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(By.xpath("//div[contains(@class, 'subjects-auto-complete__menu')]"))).click();
  

• Browser Snapshot:

The code below worked for me.

    WebDriver Driver = new ChromeDriver();
    Driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);
    //Driver.manage().window().maximize();
    String url = "https://demoqa.com/automation-practice-form";
    Driver.get(url);
    WebElement products=Driver.findElement(By.id("subjectsInput"));
    products.sendKeys("English");
    products.sendKeys(Keys.ARROW_DOWN);
    products.sendKeys(Keys.ENTER);
