First Steps with Selenium RC

• Selenium IDE only works with Firefox so we have only

been checking a small subsection of the browsers that our

users prefer

• Selenium Remote Control was initially developed by Patrick

Lightbody as a way to test all of these different web

browsers without having to install Selenium Core on the

web server

• It was developed to act as a proxy between the application

under test and the test scripts. Selenium Core is bundled

with Selenium Remote Control instead of being installed on

the server.

I. What is Selenium Remote Control

This change to the way

that Selenium tests are

run allowed developers

to interact with the

proxy directly giving

developers and testers a

chance to use one of the

most prominent

programming languages

to send commands to

the browser


• Java and C# have been the main languages used by

developers to create Selenium Tests. This is due to most

web applications being created in one of those languages.

• Ruby and Python are the most popular languages that

people are moving to.

• Using programming languages to write your tests instead

of using the HTML-style tests with Selenium IDE

make your tests more robust and take advantage of

all setups and tear down those that are common in most

testing frameworks.


• Selenium Remote Control is required on all machines that

will be used to run tests. It is good practice to limit the

number of Selenium Remote Control instances to one per

CPU core

• Limiting the Selenium instances to one per core makes sure

that the browsers load cleanly and Selenium will run as

quickly as possible

1. Download Selenium Remote Control from http://seleniumhq.org/download.

2. Extract the ZIP file.

3. Start a Command Prompt or a console window and

navigate to where the ZIP file was extracted.


4. Run the command java –jar selenium-server-standalone.jar and

the output should appear similar to the following screenshot

we have finished setting up Selenium Remote Control we

can have a look at running our first set of tests in a number of

different browsers

II. Setting up Selenium Remote Control

we have only been able to test our applications in Firefox

the testing coverage that you are offering is very limited

Browser and operating system combinations can mean that a

developer or tester will have to run your tests more than

nine times. to make sure that you cover all the popular

browser and operating system combinations.

To run our tests in Selenium Remote Control we will have

to use the –htmlsuite argument. Our command in

Command Prompt or a console window will be similar to

the following snippet:Java –jar selenium-server-standalone.jar –htmlsuite *firefox

http://book.theautomatedtester.co.uk c:\path\to\testsuite.html

c:\path\to\result.html

III. Running Selenium IDE tests with

Selenium RC

1. Open a Command Prompt or console window.

2. Use the following command:

Java –jar selenium-server-standalone.jar –htmlsuite *firefox

http://book.theautomatedtester.co.uk "c:\book\chapter

6\testsuite.html" "c:\book\chapter 6\result.html"


Selenium RC

When the test starts running it will launch two browser

windows. The first window will hold the Selenium Core

Framework with the Test Suite on the left-hand side, the test

steps in the center, and the results on the right-hand side.


Selenium RC

Using the –htmlsuite argument, we have managed to run

our Selenium IDE tests through Selenium Remote Control.

When the tests have finished it will write the results to a

file in a HTML format showing which tests have passed or

failed and the command that it may have failed on


Selenium RC


Selenium RC

1. Open up a Command Prompt or console window.

2. Use the command java –jar selenium-server.jar –htmlsuite *iexplore

http://book.theautomatedtester.co.uk c:\path\to\testsuite.htmlc:\path\to\result.html

and press Return .


Selenium RC

1. Open up a Command Prompt or console window.

2. Run the following command: java –jar selenium-server.jar –

htmlsuite *googlechrome http://book.theautomatedtester.co.uk c:\path\

to\testsuite.html c:\path\to\result.html and press Return.


Selenium RC

1. Open a Command Prompt or console window.

2. Run the following command:java –jar selenium-server-standalone.jar –userExtensions \\path\to\extensions.js -

htmlsuite *firefoxhttp://book.theautomatedtester.co.uk c:\path\to\testsuite.html

c:\path\to\results.html

Now that you have seen your tests running in Mozilla

Firefox, Internet Explorer, and Google Chrome, try running

your tests in another browser. This can be from the list of

supported browsers, or using the *custom attribute.


Selenium RC

-port

Adding –port <port number> allows you to use a different port

number without conflicts.

-userExtensions

By using –userExtensionsc:\path\to\file.js we can access all the extra

commands in our tests.

-firefoxProfileTemplate

If you require a special profile, or if you need to make sure

that a specific Firefox Add-on is installed,

use –firefoxProfileTemplate/path/to/firefox/profile.

This command will take the profile that you want and then

clone it to be used in your test.

IV. Selenium RC arguments

Selenium Remote Control: We had a look at how Selenium

Remote Control works. It is a proxy web server that sits

between our tests which are running and the web application

Setting up Selenium Remote Control: We saw how

Selenium Server and Selenium are just Java .jar files that can

run from a Command Prompt.

Running Selenium IDE tests within Selenium Remote

Control: we had a look at how we can use all the test cases

we created in previous chapters to test our web applications

Selenium Remote Control arguments: we had a look at the

rest of the Selenium Remote Control arguments that we may

need in our tests
