Filtering and performing actions on WebElements

Let's further modify the search test and find a product matching with a given name. We will then click on the product to open the product details page, as shown in this code:

@Test
 public void searchAndViewProduct() {

     // find search box and enter search string
     WebElement searchBox = driver.findElement(By.name("q"));

     searchBox.sendKeys("Phones");

     WebElement searchButton =
             driver.findElement(By.className("search-button"));

     searchButton.click();

     assertThat(driver.getTitle())
             .isEqualTo("Search results for: 'Phones'");

     List<WebElement> searchItems = driver
             .findElements(By.cssSelector("h2.product-name a"));

     WebElement product = searchItems.stream()
             .filter(item -> item.getText().equalsIgnoreCase("MADISON EARBUDS"))
             .findFirst()
             .get();

     product.click();

     assertThat(driver.getTitle())
             .isEqualTo("Madison Earbuds");
}

In the preceding code, we used the filter() function to find a specific product from the list of WebElements. We retrieved the first matching product, using the findFirst() function. This will return a WebElement representing the link element. We then clicked on the element to open the product details page in the browser.

Thus, we can use Streams API in a number of ways to create functional, readable code with just a few lines.
