15 Free Functionality And Load Testing Tools For Web Applications
Automated web application testing is done very rarely & it is generally thought as an unnecessary + hard to setup system.
Truth is, automated testing is a must, because it saves so much time during development & when the project is live. Also, with the right tools, it is generally very easy to setup.
Using testing tools, once the scenarios are created, you can:
- test every feature of the whole application with a click
- get written reports instantly with the error logs
- measure the capacity of your web application on every step
- get a continiously-watched, less-problematic web application as the result
There are 2 important web application tests to measure if everything is working (and will work) on your website:
- Functionality testing: using record-playbacks or scripting, a tool can browse your website, fill forms, click on the links you want & generate a report for you
- Load/stress testing: even if a web application is working ok with 1 or 10 users, it can show totally different attitudes (like bottlenecks in resource usage) when there are 100 or 1000 active users.
So, here is a collection of 15 Free Functionality And Load Testing Solutions For Web Applications to create better online experiences:
Selenium has various projects that can be combined with each other to create a robust testing environment.
- Selenium IDE: a Firefox add-on to record and playback tests in Firefox.
- Selenium Remote Control: a client/server system to control web browsers locally or on other computers, using almost any programming language and testing framework.
