Tips and Tricks
Using Drag and Drop
It
may not be immediately obvious, but if you're using a browser that
supports it , you can use Action classes and then it's easy to do drag
and drop:
Actions builder = new Actions(driver);
Action dragAndDrop = builder.clickAndHold(someElement)
.moveToElement(otherElement)
.release(otherElement)
.build();
dragAndDrop.perform();
Currently, only the
FirefoxDriver supports this, but you should also expect support for the
InternetExplorerDriver too.
Changing the user agent
This is easy with the
FirefoxDriver:
FirefoxProfile profile = new FirefoxProfile();
profile.setPreference("general.useragent.override", "some UA string");
WebDriver driver = new FirefoxDriver(profile);
Tweaking an existing Firefox profile
Suppose
that you wanted to modify the user agent string (as above), but you've
got a tricked out Firefox profile that contains dozens of useful
extensions. There are two ways to obtain this profile. Assuming that the
profile has been created using Firefox's profile manager ("firefox
-ProfileManager"):
ProfilesIni allProfiles = new ProfilesIni();
FirefoxProfile profile = allProfiles.getProfile("WebDriver");
profile.setPreferences("foo.bar", 23);
WebDriver driver = new FirefoxDriver(profile);
Alternatively, if the profile isn't already registered with Firefox:
File profileDir = new File("path/to/top/level/of/profile");
FirefoxProfile profile = new FirefoxProfile(profileDir);
profile.setPreferences(extraPrefs);
WebDriver driver = new FirefoxDriver(profile);
Enabling features that are disabled by default in Firefox
Native
events is such a feature: It is disabled by default for Firefox on
Linux as it may cause tests which open many windows in parallel to be
unreliable. However, native events work quite well otherwise and are
essential for some of the new actions of the Advanced User Interaction.
To enable them:
FirefoxProfile profile = new FirefoxProfile();
profile.setEnableNativeEvents(true);
WebDriver driver = new FirefoxDriver(profile);
How to set language in profile
profile.setPreference( "intl.accept_languages", "no,en-us,en" );
