I'm trying to retrieve a JavaScript global variable's value and I always get undefined when I run the test in FireFox.
This test is successful in Chrome.
index.html
<html>
<head>
<script type="text/javascript">
window.seleniumTesting = "Just A Test";
</script>
</head>
<body>
....
</body>
</html>
Test.java
WebDriver drive = new FirefoxDriver();
driver.get("http://localhost");
// Wait for the page to load. I know there are better ways of doing this.
synchronized (Thread.currentThread()) {
try {
Thread.currentThread().wait(55000);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
String str = (String)((JavascriptExecutor) driver).executeScript("console.info(window.seleniumTesting); return window.seleniumTesting;");
System.out.println("str: |"+str+"|");
When I run this, str is null and in the browser's JavaScript console window.seleniumTesting is logged as undefined.
If I use a ChromeDriver instead of FirefoxDriver. Everything is as expected (str is Just A Test and the console logs: Just A Test).
This seems to be a JavaScript context problem. It seems that in FirefoxDrive the JavaScript context is not the web page's context.
Is this a known issue ? Can I change the driver's JavaScript context to the web page's context ?
[EDIT]
I'm using the geckodriver for OSX.
[EDIT] And FireFox version 47.

With the geckodriver currently v0.10.0, you must use window.wrappedJSObject to access a non-standard property of the window object:
String str = (String)((JavascriptExecutor)driver).executeScript("return window.wrappedJSObject.seleniumTesting;");
