How to test better with add-on(s)?

You must have known the add-on(s) mindmap which we (Moolyavans) created (URL: Now, here I am going to put some light on how we can use them. I have chosen some add-on(s) where I have mentioned about how we can utilize them in our testing activity. Here I go,


Web Developer Add-on

There are different categories under Web Developer add-on and below are some and explanation on how we use them in our testing activity;

1. Validation

I would use this add-on to quickly validate CSS, HTML, find broken links or 404 pages. We would be using tools from W3C which is a standard and that would help me to give a quick report.

2. Forms

Under this I would get to know the risks like; server side validation is being done or not, maxlengths could be by-passed and get some system error message or any unexpected behaviour, can the methods of forms be converted from GET to POST and vice-versa

3. Images

This helps in performing section 508 standard tests (Web Accessibility) in very quick approach. We use navigate to a page and click on “Display ALT / Title attributes” and in the page itself all the list is displayed including existing ones and non-existing ones (No need of hovering over every image and seeing whether ALT or tooltip is visible).


Resolution Test

I use this to get coverage on how a web page looks on different screen resolutions. Some might have different resolutions set and this add-on would help us quickly to know if there are any risks associated with resolution of a webpage.


Also try ScreenFly ( which can provide resolution for Tablets like iPad / Motorola, Mobile Phones, Desktop and TV.



Let’s say we want to test My Profile page for new registered user. Now, this is a repetitive process if the test is about creating new users. So, we automate it very quickly. Let’s say within 30 seconds we could automate the register form (Without captcha or else we need to enter captcha and then submit the form). iMacros is supportable on Internet Explorer, Mozilla Firefox and Google Chrome; now even these iMacros which are recorded would help for running them on different web browsers except Apple Safari. This is just an example; we know many other contexts where we could use iMacros.


Form Fuzzer

I use this to populate the text fields with different characters from different character set. Example: !@#$%^&*()-+ etc. – I have test data and with just one click we populate every text field with the test data and then submit the form which helps in validation of input.


Check All / CheckFox

Let’s say there are 100 checkboxes and one of the tests for it is to check all 100 and submit the form. Now, doing it one by one takes a lot of time but, with CheckAll or CheckFox add-on I could do it within few seconds with dragging for the area that we want to check the required checkboxes or else with just one click. Even I can do inverse and uncheck.


Tamper Data / IE Tamper

I use this add-on for tampering the input values and submitting it to the server. This is man in the middle attack.


Example: Let’s say the item that I have purchased is of $100 but, there is a client side validation which is not allowing me to edit it. Now; I would use TamperData add-on and once you click on “Submit” Tamper Data shows the input in it’s own window and there I can edit it to only $10 and submit it. This helps us to find the risk if tampering of data could be done or not.


RegEx Tester

I use this add-on to test for regular expressions. Let’s say there is javascript code which exists for validation but; still the form is not fully built of functional. In this case, I need not stop my testing activity for validation. We could take those (A-Z, a-z, 0-9 etc.) regular expressions and perform the tests. So, even if the functionality is not implemented our testing is not blocked for input validation.


Edit This Cookie

I use this to reveal the risks (if any) like; modifying the cookie value and getting into different account which does not belong to us. Know the information that is being stored in cookie value; we look for what data should not be there in cookie information.



If I want to add some text (Alphabets) for 100 lines in text area we use Lipsum which is Lorem Ipsum text generator. So, I have the test data ready in few seconds.



Helps in getting the coverage on Javascript and CSS; we use this on specific page and all the code is extracted in separate window for CSS and Javascript. So, we have all this on one page and we can go through this on a single page. Even indentation feature is available which is under “Beautify CSS”. There are other cool features too which would add value.

  1. Add-ons are always my friend. But I face problems with them which are:

    1. They need update most of the time when browser is upgraded and also it is not very rare that my favorite add-ons are not compatible with my favorite browser versions.

    2. Having many add-ons make my browsing slower. Memory leaking is one of the core problems of many add-ons.

    3. Add-ons have to install individually for each browser.

    4. I have to reinstall all my add-ons when I my PC crashes. Why the browsers can’t remember my settings?

    Instead, I first look for desktop applications which works with all my browsers for the same purpose. I don’t have to bother with browser upgrade too frequently. For example:

    SnagIt: I use it for image capturing-editing.

    LinkChecker: For checking broken links

    ZAP: Instead of Tamper Data
