If you are a developer needing a platform to test your creations, or simply a user who needs an environment to test files, in this article we present the five free tools for testing applications.
rollMyFile
We start with rollMyFile, a web application with which you can view files online without downloading them to your computer. One of the main features of this tool is its wide range of formats (500 formats), so you can view popular files or those with unknown formats. rollMyFile is a free web application that works perfectly in all web browsers, even on iOS and Android devices.
Free Opener
Free Opener is one of the best applications for opening and testing files from its interface. The tool opens more than 300 formats (doc, docx, PDF, FLV, MP4, AVI, WMV, MP3, MID, WMV, AVA, PHP, ASP, CS, TIFF, RAW, BMP, JPEG, etc.). The platform includes a very simple but powerful multimedia player and the option to compress files from its environment. Free Opener is a free application available for Windows operating systems. (Requires Adobe Flash Player 10 ActiveX, Microsoft .NET Framework 4, and Microsoft Visual C++.)
Firebug
For developers of web pages or online applications, we present Firebug, a browser extension that lets you edit, debug, and monitor CSS, HTML, and JavaScript while you browse in your environment. Firebug is a free extension for the Mozilla Firefox web browser.
DocsPal
We continue with DocsPal, a web application that lets you view and convert files in almost any format. You can view multimedia files, ebooks, text documents, spreadsheets, and many other formats. The platform also gives you a URL for each file, so you can view it or share it on the Internet. DocsPal is a free web application available for all web browsers.
Samurai Web Testing Framework
We finish with a bang: Samurai Web Testing Framework, a web application testing environment. With this framework distributed as a LiveCD, you can test your development with the best free and open-source tools for testing web environments. Samurai Web Testing Framework is a free application available for Linux operating systems.
With these five tools for testing applications, you can view a file or verify whether your development meets all the features it offers.
