Selenium Testing - Automate

Selenium with Serenity

Your guide to running Selenium Webdriver tests with Serenity on BrowserStack.

Serenity repo on Github

Introduction

BrowserStack gives you instant access to our Selenium Grid of 2000+ real devices and desktop browsers. Running your Selenium tests with Serenity on BrowserStack is simple. This guide will help you:

  1. Run your first test
  2. Mark tests as pass / fail
  3. Debug your app

Prerequisites

Before you can start running your Selenium tests with Serenity, ensure you have following libraries installed:

<!-- Install using maven -->
<dependency>
    <groupId>net.serenity-bdd</groupId>
    <artifactId>serenity-core</artifactId>
    <version>1.1.10</version>
</dependency>

Run your first test

To understand how to integrate with BrowserStack, we will look at two things:

  1. A sample test case written in Serenity with Java
  2. Integration of this sample test case with BrowserStack

Sample test case

The sample Serenity test case below searches for the string “BrowserStack” on Google, and checks if the title of the resulting page is “BrowserStack - Google Search”

# Google Feature
Feature: Google Search Functionality

    Scenario: Can find search results
        When I type query as "BrowserStack"
        And I submit
        Then I should see title "BrowserStack - Google Search"  

// Google Page
@DefaultUrl("https://www.google.com/ncr")
public class GooglePage extends PageObject {

    @FindBy(name="q")
    WebElementFacade search;

    @FindBy(name="btnG")
    WebElementFacade searchButton;

    public void searchForString(String searchString) {
        search.sendKeys(searchString, Keys.ENTER);
    }

    public void submitForm() throws Exception {
        searchButton.click();
        Thread.sleep(5000);
    }

    public void titleShouldMatch(String matchTitle) {
        assertThat(this.getTitle()).containsIgnoringCase(matchTitle);
    }
}

// Google Test
@RunWith(CucumberWithSerenity.class)
@CucumberOptions(features="src/test/resources/features/single.feature")
public class SingleTest extends BrowserStackSerenityTest { }

To actually run the test case, we need to integrate with BrowserStack as follows.

Integration with BrowserStack

Note: Running your Selenium tests on BrowserStack requires a BrowserStack Username and Access Key.

To obtain your username and access keys, sign up for a Free Trial or purchase a plan.

Integration of Serenity with BrowserStack is made possible by the use of the following module:

public class BrowserStackSerenityDriver implements DriverSource {

    public WebDriver newDriver() {
        EnvironmentVariables environmentVariables = SystemEnvironmentVariables.createEnvironmentVariables();

        String username = System.getenv("BROWSERSTACK_USERNAME");
        if(username == null) {
            username = (String) environmentVariables.getProperty("browserstack.user");
        }

        String accessKey = System.getenv("BROWSERSTACK_ACCESS_KEY");
        if(accessKey == null) {
            accessKey = (String) environmentVariables.getProperty("browserstack.key");
        }

        String environment = System.getProperty("environment");
        DesiredCapabilities capabilities = new DesiredCapabilities();

        Iterator it = environmentVariables.getKeys().iterator();
        while(it.hasNext()){
            String key = (String) it.next();

            if(key.equals("browserstack.user") || key.equals("browserstack.key") || key.equals("browserstack.server")){
                continue;
            }
            else if(key.startsWith("browserstack.")){
                capabilities.setCapability(key.replace("browserstack.", ""), environmentVariables.getProperty(key));
                if(key.equals("browserstack.local")){
                    System.setProperty("browserstack.local", "true");
                }
            }
            else if(environment != null && key.startsWith("environment." + environment)){
                capabilities.setCapability(key.replace("environment." + environment + ".", ""), environmentVariables.getProperty(key));
                if(key.equals("environment." + environment + ".browserstack.local")){
                    System.setProperty("browserstack.local", "true");
                }
            }
        }

        try {
            return new RemoteWebDriver(new URL("https://"+username+":"+accessKey+"@"+environmentVariables.getProperty("browserstack.server")+"/wd/hub"), capabilities);    
        }
        catch(Exception e){
            System.out.println(e);
            return null;
        }
    }

    public boolean takesScreenshots() {
        return true;
    }
}
public class BrowserStackSerenityTest {
    static Local bsLocal;

    @BeforeClass
    public static void setUp() throws Exception {
        EnvironmentVariables environmentVariables = SystemEnvironmentVariables.createEnvironmentVariables();

        String accessKey = System.getenv("BROWSERSTACK_ACCESS_KEY");
        if(accessKey == null) {
            accessKey = (String) environmentVariables.getProperty("browserstack.key");
        }

        String environment = System.getProperty("environment");
        String key = "browserstack.local";
        boolean is_local = environmentVariables.getProperty(key) != null && environmentVariables.getProperty(key).equals("true");

        if(environment != null && !is_local){
            key = "environment."+environment+".browserstack.local";
            is_local = environmentVariables.getProperty(key) != null && environmentVariables.getProperty(key).equals("true");
        }

        if(is_local){
            bsLocal = new Local();
            Map<String, String> bsLocalArgs = new HashMap<String, String>();
            bsLocalArgs.put("key", accessKey);
            bsLocal.start(bsLocalArgs);
        }
    }

    @AfterClass
    public static void tearDown() throws Exception {
        if(bsLocal != null) {
            bsLocal.stop();
        }
    }
}

The module reads from config file where you need to put the BrowserStack Hub URL and credentials.

webdriver.driver = provided
webdriver.provided.type = mydriver
webdriver.provided.mydriver = com.browserstack.BrowserStackSerenityDriver
serenity.driver.capabilities = mydriver

browserstack.user=YOUR_USERNAME
browserstack.key=YOUR_ACCESS_KEY
browserstack.server=hub-cloud.browserstack.com
browserstack.name=[Serenity] Sample Test

environment.single.browser=chrome

Run your test on BrowserStack using following command:

# Run using maven
mvn test -P single

Mark tests as pass / fail

BrowserStack provides a comprehensive REST API to access and update information about your tests. Shown below is a sample code snippet which allows you to mark your tests as pass or fail based on the assertions in your Serenity test cases.

// Mark test as pass / fail

public static void mark() throws URISyntaxException, UnsupportedEncodingException, IOException {
  URI uri = new URI("https://YOUR_USERNAME:YOUR_ACCESS_KEY@api.browserstack.com/automate/sessions/<session-id>.json");
  HttpPut putRequest = new HttpPut(uri);

  ArrayList<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
  nameValuePairs.add((new BasicNameValuePair("status", "completed")));
  nameValuePairs.add((new BasicNameValuePair("reason", "")));
  putRequest.setEntity(new UrlEncodedFormEntity(nameValuePairs));

  HttpClientBuilder.create().build().execute(putRequest);
}

A full reference of our REST API can be found here.

Debug your app

BrowserStack provides a range of debugging tools to help you quickly identify and fix bugs you discover through your automated tests.

  • Text Logs

Text Logs are a comprehensive record of your test. They are used to identify all the steps executed in the test and troubleshoot errors for the failed step. Text Logs are accessible from the Automate dashboard or via our REST API.

  • Visual Logs

Visual Logs automatically capture the screenshots generated at every Selenium command run through your Serenity tests. Visual logs help with debugging the exact step and the page where failure occurred. They also help identify any layout or design related issues with your web pages on different browsers.

Visual Logs are disabled by default. In order to enable Visual Logs you will need to set browserstack.debug capability to true:

browserstack.debug = true
  • Video Recording

Every test run on the BrowserStack Selenium grid is recorded exactly as it is executed on our remote machine. This feature is particularly helpful whenever a browser test fails. You can access videos from Automate Dashboard for each session. You can also download the videos from the Dashboard or retrieve a link to download the video using our REST API.

Note: Video recording increases test execution time slightly. You can disable this feature by setting the browserstack.video capability to false.

browserstack.video = false

In addition to these logs BrowserStack also provides Raw logs, Network logs, Console logs, Selenium logs, Appium logs and Interactive session. Complete details to enable all the debugging options can be found here
