Test automation is the use of specialized software tools to control the execution of tests and compare actual test results with expected results. Test automation can be applied to various types of software testing, including functional testing, regression testing, performance testing, and more. One of the key benefits of test automation is that it can significantly reduce the cost of software testing while improving its quality and reliability.
Here are some of the ways that test automation can impact costs:
Reduced Testing Time and Effort Test automation can significantly reduce testing time and effort. According to a report by Capgemini, test automation can reduce testing time by up to 40% and testing effort by up to 60%. This can result in significant cost savings, particularly for large and complex software projects.
Increased Testing Coverage A study by the National Institute of Standards and Technology (NIST) found that test automation can increase testing coverage by up to 80%. The study compared the effectiveness of manual testing to automated testing for software applications and found that automated testing resulted in a higher level of coverage.
Improved Accuracy Test automation can improve testing accuracy by up to 90%, according to a report by IBM. This can reduce the risk of releasing software with defects, which can result in costly rework and damage to the organization's reputation.
Reduced Labor Costs Test automation can reduce testing costs by up to 50%, according to a report by TechWell. This includes direct labor costs associated with testing and indirect costs such as lost productivity due to manual testing.
Reduced Hardware Costs Test automation can reduce hardware costs by up to 40%, according to a report by Gartner. This includes the cost of physical hardware required to support testing, as well as the cost of maintaining and upgrading hardware over time.
Gartner's report highlights that test automation can help organizations reduce the number of physical test environments required for testing, as well as the complexity of those environments. By using virtualization and cloud-based testing platforms, organizations can reduce the need for physical hardware, leading to significant cost savings.
In conclusion, test automation can result in significant cost savings across a range of software testing activities. These savings can be quantified in terms of reduced testing time
and effort, increased testing coverage, improved accuracy, reduced labor costs, and reduced hardware costs. By adopting test automation, organizations can improve the quality and reliability of their software while reducing the cost of software development and maintenance.
