validation testing tool freebiesAs you probably know already, it’s important to check and test your Website to help ensure that it looks great and works beautifully regardless of the browser or platform used. Testing a website before launch is one thing that you cannot afford to take lightly.  Just like a minor negligence while constructing a building can cost life of millions of residents , the same way a small error left unnoticed can prove to be fatal for your website.

Therefore, this implies that we must run our website through all necessary tests. This includes CSS Errors, HTML Errors, Cross browsing Errors, WAP Errors (if your site is WAP enabled) and various other tests.Below is the list of Online Tools for Website Validation and Testing. So make it sure that you go through this post and run all the necessary tests on your website before making it live.

Validation tools

1.W3C markup validation service

This validator checks the markup validity  of Web documents in HTML, XHTML, SMIL, MathML, etc. This is an exclusive standards check for the document, so other checks are not available.

Checks done on:

  1. Syntax and style analysis – Yes
  2. Source code – Yes

2.CSS validator

Check Cascading Style Sheets (CSS) and (X)HTML documents with style sheets.The important thing is if you want to validate your CSS style sheet embedded in an (X)HTML document, you should first check that the (X)HTML you use is valid.

3.Checklink

Check links and anchors in Web pages or full Web sites.This Link Checker looks for issues in links, anchors and referenced objects in a Web page, CSS style sheet, or recursively on a whole Web site. For best results, it is recommended to first ensure that the documents checked use Valid (X)HTML Markup and CSS.

6.Unicorn

  3. Word counts – Yes
  4. Spelling checks – Yes
  5. Link checking – Yes

10.Robots checker

    Great evaluation. Thank you for this.

    May I ask if there are cross browser tool that fits my below needs:
    1. Can take screenshots of secure application page(e.g. page that required logins yahoomail.com for example) at once.
    2. Live testing: By entering the URL once it will run for multiple browsers.
    3. Live testing: By entering the URL once and loggin in at 1 user only it will run for multiple browsers.

    Thank you in advance!

    Apologies if this rains on this parade but:
    ‘Pingdom’ can be made redundant with ‘Firebug’ (Firefox add-on) – Net tab.
    ‘IE Renderer’ can be made redundant by ‘IETester’.
    ‘Webpage Analyzer’can be made redundant by ‘YSlow’ (Firefox add-on).
    ‘HTML Validators’ can be made redunant by the ‘W3C Validator’ that’s built into ‘Web Developer’ (Firefox add-on)…’HTML tidy’ (Firefox add-on) can be helpful too (as Matthew Fedak mentioned).
    If you’re using WordPress, then the ‘Broken Link Checker’ (WP Plug-in) makes ‘CheckLink’ redundant.

    I only say redundant because – as you can see – my suggestions are merely Firefox add-ons; tools you can access without leaving your development environment.

    I used brokenlinkcheck.com and liked it – you don’t get needles info in the report but it never misses a single broken link.

    You know, nowadays sometimes it’s easier and faster to download the file you need from internet than search it on pc XD But that’s a good piece of soft anyway, thanks for the share. By tha way if you need to search pds in internet you can use http://www.usemeplz.com search engine, that one is my favorite.

    Some great web developer tools left out in this post are html tidy plugin for firefox and web developer tool for firefox, checking for web standards and browser compatibility is good but these need to be done throughout the web development process. I believe html tidy and web developer toolbar which both have validation alogrithms built in use W3 validator api in someway anyhow.
