Undocumented way to select a node on a Selenium Grid2

[Juan Antonio Ruzafa]

There is an undocumented way to select a node in a grid to test your
application. You can use the "applicationName" capability to do this.
Currently, there is no way for Selenium to diference between 32 and
64 bits version of a given OS. So if you want to test with a specific
version you could setup the nodes as:

NODE1:
java -jar selenium-server-standalone-2.20.0.jar -role node -hub
http://HUB_IP:4444/grid/register -browser
browserName=firefox,version=11,maxInstances=1,platform=WINDOWS,applicationName=windows7_32bits_firefox_11

NODE2:
java -jar selenium-server-standalone-2.20.0.jar -role node -hub
http://HUB_IP:4444/grid/register -browser
browserName=firefox,version=11,maxInstances=1,platform=WINDOWS,applicationName=windows7_64bits_firefox_11

In your tests you have to add
"applicationName=windows7_32bits_firefox_11" to your desired
capabilities array.


You can see the source code at:
http://code.google.com/p/selenium/source/browse/trunk/java/server/src/org/openqa/grid/internal/utils/DefaultCapabilityMatcher.java

public DefaultCapabilityMatcher() {
toConsider.add(CapabilityType.PLATFORM);
toConsider.add(CapabilityType.BROWSER_NAME);
toConsider.add(CapabilityType.VERSION);
toConsider.add("applicationName");

}


BTW, it would be nice that someone adds this information to Grid2 wiki
page.

Thanks for the tip. I'll try it out sometime. This could be useful for
other things like specifically naming nodes (for particularly config,
etc.) and as such then integrate with tools like AutoIt or Sikuli in a
Grid2 config.

As I understand it platform is simply a string that gets matched. All
you would need to do is set it to WINDOWS64 for your node and do the
same for when you want to run a Win64 test. No need to use an
undocumented, and hence unreliable, method that may disappear on you
or be co-opted for other uses later.

I dont think you can change the value of Platform to anything apart from what is defined in the Platform enum class. 

So it wont work if you change it to anything else.

Hi Mike, your method doesn't work due platform string it's actually an
enumerated class so you can not simply assign an arbitrary value to it
(I've tested it!).

You've got the point that an undocumented method is unreliable for
future versions, this is why I hope this "undocumented" method turns
to a "documented" method soon!

I've submitted an issue with this info.

I see what you mean, now that I looked at the code.  I thought those were simply predefined strings, but that any arbitrary one could be used.  That would certainly be more flexible.

So far 64-bit versus 32-bit has not been an issue for us.
