The browser type and other configuration options can be defined in the twist.properties file.

The following Selenium 2 options are supported in Twist:

• webdriver.browser (Browser): This is used by Selenium 2 to launch the browser. Possible property codes for browser are chrome, firefox, ie, htmlunit, iphone, android. Note, on the properties gui they will be displayed as Chrome, Internet Explorer etc.
• webdriver.browser.script (Browser Script Location- optional): This is the path of the browser launcher file. This can point to a script launching the browser as well. If this property is not provided, webdriver looks in the standard browser locations (eg. "c:\Program Files\Internet Explorer\iexpolre.exe" for IE in windows)
• webdriver.browser.profile (Browser Profile - optional): This is the path where a browser profile exists, either for FireFox or Chrome.
• webdriver.browser.nativeEvents (Enable Native Events - optional): This is applicable for Firefox browser and to enable native event interaction with OS. Default is false.
• webdriver.reap_profile (Reap Profile - optional): Should be "true" if temporary files and profiles should not be deleted.


HtmlUnit specific Options:


• webdriver.browser.version (Browser version - optional): This setting is only applicable for HtmlUnit and indicates the browser HTMLUnit may configure for. Possible values are FIREFOX_3, FIREFOX_3_6, INTERNET_EXPLORER_6, INTERNET_EXPLORER_7, INTERNET_EXPLORER_8.
