What does it do?

Provides Hub and Node Config

Provides Sample Test

How Do I Get it to Work?

RTFR! (Read the Fine ReadMe!)*

1. Put the grid-setup/hub directory on your

hub (if your hub is a windows box, you'll need

to rename the executable 'starthub' to

something like 'starthub.cmd' and fix the

link).

7

How Do I Get it to Work?

2. Put the appropriate grid-setup/*-node

directory/ies on your node/s along with the

selenium-server-standalone-<version>.jar

(if you change the version, change the links

in the startup scripts to match).

8

How Do I Get it to Work?

3. Update the JSON configs with the ip of your

hub and the ip of each of your nodes.

(search for *.json – there is one in each of

the *-node directories under selenium-grid-

setup\grid-setup, and named for the operating

system: e.g. nodeconfig-win81.json)

9

How Do I Get it to Work?

4. Run grid-setup/starthub on the hub

5. Run grid-setup/startnode-* on your nodes

Done! You have a grid. You can check the

connections from your browser at

http://localhost:4444/grid/console on your

hub machine

10

OK, Now What?

Run the Sample Test:

Nav to grid-test/helpers

Run isgridup.sh

11

OK, Now What?

Sample Test Results:

All nodes navigate to address specified in VerifyTest.java

12

OK, Now Now What?

Run Your Own Tests on the Grid: • Use Selenium IDE to generate Java code for your test

• Extend RemoteTest to integrate it into the grid OR just plug it into VerifyGrid.java

• Run your test on the grid
