The Benefits of Automation and Tools
Background
Regression testing: This process of rerunning your tests is known as regression testing.
The work of regression testing is enormous
Software test tools and automation can help solve this problem by providing a more efficient means to run your tests than by manual testing.
.
The Benefits of Automation and Tools
The principal attributes of tools and automation are
Speed.
Efficiency.
Accuracy and Precision.
Resource Reduction.

Test Tools
As a software tester you'll be exposed to a wide range of testing tools. The types of tools that you'll use are based on the type of software that you're testing and whether you're performing black-box or white-box tests.

Test Tools
The major classes of testing tools and how they're used.
