How Can Selenium and Java Select Auto-Suggestions from Dynamic Dropdowns?

Selecting Auto-Suggestions from Dynamic Dropdowns using Selenium and Java

In the context of web automation, selecting values from dynamic dropdowns can be a daunting task. Take, for instance, the Subjects field in the form found at https://demoqa.com/automation-practice-form. This input field dynamically presents suggestions based on user input, and the challenge lies in selecting the desired value from these suggestions.

One common approach is to rely on the element's ID and sendKeys() method to populate the input field. However, this alone is insufficient for selecting the value. The code snippet provided in the question, while populating the input area, fails to select the value.

To overcome this issue, we must adopt a more comprehensive strategy. The solution, as demonstrated in the provided answer, involves the use of arrow keys (Keys.ARROW_DOWN) and the Enter key (Keys.ENTER). Here's a breakdown of the updated code:

WebDriver Driver = new ChromeDriver();
    Driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);
    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);

This refined code performs the following actions:

1. It sends the input text ("English") to populate the input field.
2. It sends the down arrow key to navigate to the desired suggestion.
3. Finally, it sends the Enter key to select the highlighted suggestion.

By incorporating these keystrokes, the code successfully selects the desired value from the dynamic dropdown, ensuring accurate and efficient test automation.
