Using the Map function to get the text value from elements

In this example, we will modify the search test we created in earlier chapters to test the results containing the list of expected products, as shown in the following code:

@Test
public void searchProduct() {

    // 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"));

    List<String> expectedProductNames =
            Arrays.asList("MADISON EARBUDS",
                    "MADISON OVEREAR HEADPHONES",
                    "MP3 PLAYER WITH AUDIO");

    List<String> productNames = searchItems.stream()
            .map(WebElement::getText)
            .collect(Collectors.toList());

    assertThat(productNames).
            isEqualTo(expectedProductNames);

}

In the preceding code, we created a list of all the matching products returned by the findElements() method. We then retrieved the text of each element by calling the map() function and mapped the return values to a list of strings. This is compared with the expectedProductNames list.
