Mobile App Europe 2014 Notes

Workshop Selenium, Selendroid and ios-driver Mobile and Web Automation Using One API and One Infrastructure

Notes on a workshop by Michael Palotas (Gridfusion, eBay) at the Mobile App Europe 2014.

• End-to-end-test over different devices (desktop - mobile - tablet)
• Ability to directly access an API or a database
• Selenium webdriver is becoming a W3C standard -> Every browser will support Selenium!
• Selenium Grid - scale tests to several nodes (different OS/browser)

##Webdriver Protocol

• AKA “JSON wire protocol”
• Client with bindings to several languages (C#, Java, Ruby, Python, …)
• JSON Wire Protocol

• Server to be downloaded for each browser (except FireFox - in standard Selenium JAR)

• Selendroid and iOS-Driver for the mobile browsers

nuget Package for .NET:

install-package Selenium.WebDriver
install-package Selenium.WebDriver.ChromeDriver
install-package Selenium.WebDriver.IEDriver

Example:

[TestMethod]
public void BrowsingWithLocalDriver()
{
    using (var driver = new FirefoxDriver())
    {
        driver.Url = "http://paulroho.com";
        driver.Title.Should().Contain("PaulRoho.com");
    }
}

##Remote web driver

install-package Selenium.RC

##Selenium Grid

• Environment Management & Control
• Scaling
• Parallel execution of tests (eBay tests if sequentially executed would take 6 days to complete)
• Reduction of execution times
• Crossover tests (web, mobile)
• Sits between my world (Dev, CI, …) and machines with difference browsers (linux, windows, OSX, …)
• Nodes registers with selenium grid hub with capabilities (os version, browsers, versions)
• Tests are sent to grid hub along with desired capabilities

-

1. Download the Selenium server from Selenium Download Page.

2. Startup the hub

   java -jar selenium-server-standalone-2.41.0.jar -role hub

http://localhost:4444/grid/console

java -jar selenium-server-standalone-2.41.0.jar -role wd -hub http://localhost:4444/grid/register

Now the grid can be targeted by using the RemoteWebDriver:

[TestMethod]
public void BrowsingUsingSeleniumGrid()
{
    var capability = DesiredCapabilities.Firefox();
    using (var driver = new RemoteWebDriver(new Uri("http://localhost:4444/wd/hub"), capability))
    {
        driver.Url = "http://paulroho.com";
        driver.Title.Should().Contain("PaulRoho.com");
    }
}

##Reporting

reporter.log("This is additional info");

##Mobile Automation Requirements

• Reuse of the existing Selenium infrastructure for the web
• Implementation of the Selnium protocol
• The application under test should not need to be modified
• Support for emulators/simulators as well as real deveices
• Parallel execution of tests in a Selenium Grid
• Management of multiple applications, versions, language
• Support for runtime instpection for the app
• Hybrid app support

• No jailbreaking of device required

• iOS-driver
• Selendroid

##Setup for selendroid:

DesiredCapabilitis.android()
capability.setCapability(SelendroidCapabilities.EMULATOR,true);
...

Possible to define the desired locale in the capabilities

Possible to inspect the native app’s Dom.
