Rock & Roll With Http Level Testing

Article written by Sreenivas Mothukuru

In continuation to my previous topic (My approach towards automation)

There are many tools available on web to test at http level. However, I explored Web Inject tool and found the tool very handy & simple to impliment http level testing.

Follow below steps to run http level tests to check form validations and apache redirections for http://www.blogger.com/ web site.

1) Download “webinject-1.41.win32.zip - MS Windows Executable + Source Code” from http://www.webinject.org/download.html location).


2) Un-zip “webinject-1.41.win32.zip” and copy folder to some drive/location.

3) In Config.xml (within Web Inject folder), replace entire content with
********************************************************
<testcasefile>sampleTest.xml</testcasefile>
********************************************************
4) Create a file named “sampleTest.xml” (within Web Inject folder) and copy below content to the file.

    verifyresponse="The username or password you entered is incorrect"
/>

</testcases>

********************************************************
5) Test Cases 1, 2 & 3 validate apache redirections and Test Cases 4, 5 & 6 validate form validations for Blogger site.

6) To open Web Inject client application double click on “webinjectgui.exe” file (within Web Inject folder).


7) Now, click on “Run” button.

8) That’s all; you can see http tests running on the same window with results. You can monitor the response time while tests are running. Detailed test results can be viewed at “results.html” file (within Web Inject folder). Also, select “Response Timer Output” checkbox to know the response time for each http request.

Observations (form validation & apache redirection tests for blogger.com):

- "sampleTest.xml" http level test script took ~11 seconds to execute all cases.
- same tests at browser level (using Selenium) took ~25 seconds to execute all cases.

Note:
- Follow below links to know more about http level automation using Web Inject.

- Example mentioned in this blog is very basic and trivial. To make the example easy to understand I didn't use methods provided by Web Inject. Http tests can be well maintained if Test Engineers efficiently use all available WebInject methods.

  2. Deepak,

    Using Firebug (Firefox add-on) tool we can check requests and responses at browser level.

    Follow below steps to see request and response headers for "Get" and "Post" requests.
    1) Go to https://addons.mozilla.org/en-US/firefox/
    2) Search for “firebug” add-on.
    3) Select "firebug" from search results and add it to Firefox browser.
    4) After installing Firebug on Firefox restart (close and open) Firefox browser.
    5) Click on “Tools” (Alt + T), select “Firebug” and click on “Open Firebug” or Select 'F12'.
    6) Select “Net” tab (click on “All”).
    7) Access http://www.blogger.com/home URL.
    8) Provide Email, password and click on “Sign in” button (Now check request and responses using firebug).
    9) You can see post request in Firebug window (i.e. https://accounts.google.com/ServiceLoginAuth).
    10) Expand (Click on ‘+’) Post request, click on “Post”, scroll down and look at the “Source” section. You can find all “Post” parameters.

    Feel free to ping me if you need any help / if you have any questions.

    Thanks,
    Sreenivas

  4. Deepak,

    Share test login and password with the URL information (i.e. http://www.moodle.org). I'll work on it when I find some free time.

    Thanks,

  5. Deepak,

    Looks like your site (http://www.moodle.org) is pretty much simple to automate at http level. Send user name and password to my email account (heysreeni@gmail.com). I'll get back to you with test scripts.

    Regards,
    Sreenivas
