Selenium WebDriver at Cucumber

Our earlier session we created Gherkin feature files and generated class definition according it, In this session we are going to add Selenium WebDriver on every step to control browser. We will do this process 2 way:

First we will see the whole Implementation
Then will see the every method explanations

Full implemented class

You can copy the full implementation and paste to your project as well. Notice: Sometime Google change their css class name, if the code throw class not found exception please let me know.

        webDriver = new ChromeDriver();
        webDriver.manage().window().maximize();
    }

    @Given("Open google.com")
    public void open_google_com() {
        webDriver.manage().timeouts().implicitlyWait(5, TimeUnit.SECONDS);
        webDriver.get(baseUrl);
    }

    @When("Entering number {int} and {int}")
    public void entering_number_and(Integer first, Integer second) {
        WebElement googleTextBox = webDriver.findElement(By.className("gLFyf"));
        googleTextBox.sendKeys(first + " + " + second);
    }

    @When("Press enter")
    public void press_enter() {
        WebElement searchButton = webDriver.findElement(By.className("gNO89b"));
        searchButton.click();
    }

    @Then("Result should be {int}")
    public void result_should_be(Integer result) {
        WebElement calculatorTextBox = webDriver.findElement(By.className("qv3Wpe"));
        Integer getResult = Integer.parseInt(calculatorTextBox.getText());
        Assert.assertEquals(getResult, result);
        webDriver.close();
    }

    @After
    public void end() {
        if (webDriver != null) {
            webDriver.quit();
        }
    }

}

Every step explanations

Here we explain the steps of full implementation, you also find the method action definition of previous chapter.

Global Variables

Declaring global variables for access them all over the project.

    private WebDriver webDriver;
    private String baseUrl = "https://www.google.com";

Instantiate Chrome WebDriver

Instantiating Google Chrome browser driver, the driver stored in our project root >> driver Before run please make sure your chrome browser version and chrome driver versions are same, otherwise it will not able to run project. If you not familiar on it then please see Chrome version check and download driver. After Instantiate it’s maximize the browser.

    @Before
    public void setup() {
        System.setProperty("webdriver.chrome.driver", "driver/chrome-driver-81.0.4044.69.exe");
        webDriver = new ChromeDriver();
        webDriver.manage().window().maximize();
    }

Open google.com into browser

Wait 5 second and then open google.com at chrome browser.

    @Given("Open google.com")
    public void open_google_com() {
        webDriver.manage().timeouts().implicitlyWait(5, TimeUnit.SECONDS);
        webDriver.get(baseUrl);
    }

Enter 2 number into google search bar

Take 2 numbers from gherkin feature file and put them to google search text box.

    @When("Entering number {int} and {int}")
    public void entering_number_and(Integer first, Integer second) {
        WebElement googleTextBox = webDriver.findElement(By.className("gLFyf"));
        googleTextBox.sendKeys(first + " + " + second);
    }

Click or press enter for calculation

After put numbers in google text box clicking search button for result.

    @When("Press enter")
    public void press_enter() {
        WebElement searchButton = webDriver.findElement(By.className("gNO89b"));
        searchButton.click();
    }

Compare actual value and expected value

Comparing Search result with value comes from gherkin feature file.

    @Then("Result should be {int}")
    public void result_should_be(Integer result) {
        WebElement calculatorTextBox = webDriver.findElement(By.className("qv3Wpe"));
        Integer getResult = Integer.parseInt(calculatorTextBox.getText());
        Assert.assertEquals(getResult, result);
        webDriver.close();
    }

End of the Test

Closing browser when the full process completed.

    @After
    public void end() {
        if (webDriver != null) {
            webDriver.quit();
        }
    }
