DesiredCapability For Cloud Environment SauceLabs Vs BrowserStack

Additional Keys Are Supported For Setting Desired Capabilities W.R.T execution on cloud environment:

1. Account Name: username=<AccountName>
2. AccessKey : accessKey=<AccessKey>

Example:
/*Below snippet does belong to C# conventions*/
private void setRemoteWebDriverForCloudSauceLabs()
        {
            DesiredCapabilities desiredCapabilities = new DesiredCapabilities();
            desiredCapabilities.SetCapability(CapabilityType.BrowserName, this.browser);
            desiredCapabilities.SetCapability(CapabilityType.Version, this.version);
            desiredCapabilities.SetCapability(CapabilityType.Platform, this.platform);
            desiredCapabilities.SetCapability("username", this.userName);
            desiredCapabilities.SetCapability("accessKey", this.accessKey);
            desiredCapabilities.SetCapability("name", this.executedFrom + " - " + this.jobName + " - " + this.buildNumber + " - " + TestContext.CurrentContext.Test.Name);
            Uri commandExecutorUri = new Uri("http://ondemand.saucelabs.com/wd/hub");
            this.driver = new RemoteWebDriver(commandExecutorUri, desiredCapabilities);
        }

The same url for saucelabs connection can also contain username and accesskey. For example:
Uri commandExecutorUri = new Uri("http://<username>:<accessKey>@ondemand.saucelabs.com:80/wd/hub");

/*For BrowserStack*/

private void setRemoteWebDriverForCloudBrowserstack()
        {
            DesiredCapabilities desiredCapabilities = new DesiredCapabilities();
            desiredCapabilities.SetCapability("browser", this.browser);
            desiredCapabilities.SetCapability("browser_version", this.browser_version);
            desiredCapabilities.SetCapability("os", this.os);
            desiredCapabilities.SetCapability("os_version", this.os_version);
            desiredCapabilities.SetCapability("browserstack.user", this.browserstack_user);
            desiredCapabilities.SetCapability("browserstack.key", this.browserstack_key);
            Uri commandExecutorUri = new Uri("http://hub.browserstack.com/wd/hub/");
            this.driver = new RemoteWebDriver(commandExecutorUri, desiredCapabilities);
        }

Unit testing best practices

Unit testing is not about finding bugs
Tips for writing great unit tests
Test only one code unit at a time
Don’t make unnecessary assertions
Make each test independent to all the others
Mock out all external services and state
Don’t unit-test configuration settings
Name your unit tests clearly and consistently
Write tests for methods that have the fewest dependencies first, and work your way up
All methods, regardless of visibility, should have appropriate unit tests
Aim for each unit test method to perform exactly one assertion
Create unit tests that target exceptions
Use the most appropriate assertion methods.
Put assertion parameters in the proper order
Ensure that test code is separated from production code
Do not print anything out in unit tests
Do not use static members in a test class
Do not write your own catch blocks that exist only to fail a test
Do not rely on indirect testing
Integrate Testcases with build script
Do not skip unit tests
Capture results using the XML formatter

How to upload a file using selenium webdriver

Scenario:

Using selenium webdriver, one can simulate fileupload easily using sendKeys.

Using firebug, I could see, the button which pops up operating system specific dialog box where file loaction is typed-in has got type=file.

The below is snippet from naukri site, which has got button to upload file.

<input type="file" name="attachCV" id="attachCV" valtype="attachCV" class="">

In case, input type="file", we can pass absolute location of file to be uploaded using sendKeys method exposed by WebElement class.

Ex:
WebDriver wd = new FirefoxDriver();
WebElement we = wd.findElement(By.id = "attachCV");
we.sendKeys(<Absolute FileLocation>);

Internationalization Testing Using WebDriver

Internationalization Testing Using WebDriver
One need to open browser in localized mode, in specific language.

there could be 2 approaches:
i. create profile and load it during launching browser.
    --ProfileIni pf = new ProfileIni();
    --FirefoxProfile fireFoxProfile = pf.getProfile(<profileName>);//<profileName is created using profile manager, "type firefox.exe -p on Windows+R "
 
    --WebDriver wd = new FireFoxDriver(fireFoxProfile);
ii. Create object of FirefoxProfile. Set the preference of FirefoxProfile to open in particular langauage.
--FireFoxProfile fireFoxProfile = new FireFoxProfile();
--fireFoxProfile.setPreference("intl.accept_languages","sl");
--WebDriver wd = new FireFoxDriver(fireFoxProfile);

package learn.I18n;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.firefox.FirefoxProfile;
import org.testng.Assert;
import org.testng.annotations.BeforeTest;
import org.testng.annotations.Test;

Profile setting can be done using ProfileIni Class in WebDriver
*/
public class Localization implements Constants
{

WebDriver wd = null;

@BeforeTest(enabled = true)
public void setup()
{
/*
ProfilesIni pf = new ProfilesIni();
FirefoxProfile fireFoxProfile = pf.getProfile(profileName);
wd = new FirefoxDriver(fireFoxProfile);
*/
FirefoxProfile fireFoxProfile = new FirefoxProfile();
fireFoxProfile.setPreference("intl.accept_languages","sl");
wd = new FirefoxDriver(fireFoxProfile);
}

@Test
public void testLoadApplication()
{
wd.get("http://www.gmail.com");
