While developing a new software, open source testing tools can be used to identify any bugs and faulty operation. By making use of open source test management tools, you can easily maintain and upgrade your software regularly.
Open Source Testing Tools: How It Helps
Open source automation testing tools are quite popular as their source code is available for free use and designers can build additions upon the basic framework.
With the help of open source performance testing, you can examine your software or application at different stages and for different parameters such as load, regression, etc.
Not only this, open source testing tools can be used for testing of mobile and desktop applications as well in addition to software.
Benefits of Open Source Test Management Tools
