Jump Start FitNesse with Sahi using Generic Fixture

Sahi is one of the popular automated web test tool these days. Recently a comment was made by Mr Tom Heintzberger on my blog post here on Use of variables, arrays and complex types in Generic Fixture regarding use of Sahi with Generic Fixture and the problems he’s facing while trying to build DSL around it. So I decided to look into it and ended up creating a DSL myself to be used with Sahi.

Refer to Jump Start FitNesse with Selenium using Generic Fixture for detailed steps to download and install FitNesse & Generix Fixture.

Create a page on FitNesse for Sahi Web Test using Generic Fixture

  1. Open your browser and goto the URL http://localhost:8000/FrontPage. Look for the Edit button on the left hand navigation column. If Edit button is not present then goto the URL http://localhost:8000/FrontPage?properties and select the “Edit”check box and click on Save Properties. Now click on Edit button and once on the Edit Page add a new line at the end of all the text already there and save your changes.
    |[[Sahi Web Test Suites][FitNesse.SahiTestSuite]]|Sahi Web Tests|
  2. Now on the Front Page it will display a text like “Sahi Web Test Suites?” with ? as hyper link. Click on ? link.
  3. Once in the Edit Page, copy paste following text into text area and save your changes:
    !*> Class Path & Global Defines
    !path genericfixture.jar
    !path sahi.jar
    !path bsh.jar
    !define COLLAPSE_SETUP {true}
    !define COLLAPSE_TEARDOWN {true}
  4. You will notice 3 ? links on the page indicating missing pages. Now lets create each and every missing page.
  5. Click on the ? link next to SetUp text and on the “Edit Page” text area copy-paste following code and finally save your changes.
    !| DSL Adapter |
    | user starts the browser | open | |
    | user opens the URL | % | navigateTo | {1} |
    | page has the title | title | |
    | user clicks on the link named | % | GenericFixture.bsh | sahi.link( new String[] {"{1}"} ).click(); |
    | page loads in less than | % | seconds | waitFor | {1}000 |
    | user types | % | into | % | field | GenericFixture.bsh | sahi.textbox( new String[] {"{2}"} ).setValue( "{1}" ); |
    | user clicks on the button named | % | GenericFixture.bsh | sahi.submit( new String[] {"{1}"} ).click(); |
    | page has URL | fetch | location.href |
    | show | toString | |
    !| Generic Fixture| net.sf.sahi.config.Configuration |
    | initJava | /home/sahi | /home/sahi/userdata |
    !| Generic Fixture | sahi=net.sf.sahi.client.Browser | firefox |
    | user starts the browser |
  6. Go back to the page: http://localhost:8000/FitNesse.SahiTestSuite
  7. Click on the ? link next to TearDown text and on the “Edit Page” text area copy-paste following code and finally save your changes.
    !| Generic Fixture | sahi= |
    | user stops the browser |
  8. Again go back to the page: http://localhost:8000/FitNesse.SahiTestSuite
  9. Now click on ? link next to GoogleSahiTest text and on the “Edit Page” text area copy-paste following code an save your changes.
    !| Generic Fixture | sahi= |
    | isFirefox | | true |
    | user opens the URL | http://www.google.co.in |
    | user types | sahi forums | into | q | field |
    | user clicks on the button named | Google Search |
    | page loads in less than | 1 | seconds |
    | user clicks on the link named | Sahi - Web Automation and Test Tool |
    | page loads in less than | 1 | seconds |
    | page has the title | | Sahi - Web Automation and Test Tool  |
    | page has URL | | http://sahi.co.in/forums/ |
  10. After saving your changes click on Properties button from the left hand navigation menu and click on check box left to Test property and save your changes. Now you should see Test button available on the top lest navigation menu.

Execute your Google Sahi Test Page on FitNesse using Selenium

Just click on the Test click on this page: http://localhost:8000/FitNesse.GenericFixture.SahiTestSuite.GoogleSahiTest and watch how your Sahi automated web test is being run. Test will open a new Firefox browser and go to http://www.google.com and search Google with query text “sahi forums
Upon completion of test you should see this on the top of the results page:

Assertions: 3 right, 0 wrong, 0 ignored, 0 exceptions

Hope this post will help some readers trying to use Sahi Automation Testing with Generic Fixture or people facing similar issues while using other frameworks with Generic Fixture.

Introducing DSL Adapter for Generic Fixture

DSL (Domain Specific Language) is used to define problems in a specific domain. DSL, off late has gained a lot of focus due to its readability and ease of use. It is much more expressive than general purpose programming language especially for test authors, business people and end users.

When I published my Generic Fixture, there was a very valid concern raised by some FitNesse users that since Generic Fixture lets testers write their tests without writing any Java code and exposes user’s class level details (such as constructors and methods) to testers it might not be very appealing to customer and business folks as it is to developers. That’s when I started dwelling into this issue. Initially I thought of providing a MS Excel macro that lets testers write their test in DSL and by running that macro it will produce class level tests suited for Generic Fixture. But I abandoned that macro idea because of my unfamiliarity with VB and also to avoid hassle of an extra step for testers. (what if testers are writing tests directly on Wiki page rather than MS Excel). Finally I decided upon providing a plug-in kind of extension to Generic Fixture that will let testers define their own high level customer centric language (DSL). This DSL adapter will contain information on how to map it to Java Class level details. They just have to define this mapping once for each domain and can make it part of the SetUp page to make it available to for all the test pages.

Jump Start FitNesse with Selenium using Generic Fixture

Download FitNesse

Go to http://fitnesse.org/FitNesseDevelopment.DownLoad and download the the latest fitnesse.jar. Create a directory c:\program files\fitnesse\. Copy the downloaded fitnesse.jar into directory c:\program files\fitnesse. fitnesse.jar is an executable jar file so just double click this file and it will install itself.

Download Selenium Remote Control (Selenium RC)

Go to http://selenium-rc.openqa.org/download.jsp and download the latest version (1.0.3 at the time of writing this page). Unpack the zip into c:\program files\selenium\ directory. Current version for Selenium-RC is 1.0.3 and these instructions are written assuming you are using this version.

Create a smart start script

Copy and paste following script into a file called run.vbs under the directory “C:\Program Files\selenium\selenium-server-1.0.3”. This script will start both FitNesse servers and Selenium remote control servers on their default ports 8000 and 4444 respectively. This script will ONLY start these processes if these processes are not running, so this script can be safely run any time.

PS: Please note that this script is starting Selenium in an experimental Proxy Injection Mode which lets you run your web test across multiple domains. If you don’t want to use this feature feel free to change this start script.
