Software Test Automation Tools

Automated software testing is becoming more and more important for many software projects in order to automatically verify key functionality, test for regressions and help teams run a large number of tests in a short period of time.

Many teams (especially larger projects) still require a significant amount of manual functional testing in addition to automated testing, either because of the lack of sufficient resources or skills to automate all tests.

There are various tools that help software teams build and execute automated tests. Many teams are actively using unit tests as part of their development efforts to verify critical parts of their projects such as libraries, models and methods.

Historically, testing user interfaces of desktop-based applications via automated tests have been more challenging, and currently available tools for this are usually commercial and quite expensive.
With the growing number of web-based applications this is changing, however, as verifying and testing web-based interfaces is easier and there are various tools that help with this, including free open source projects. Please see below for a list of popular and useful tools, projects, books and resources to get started with automated software testing.
