As mentioned previously, automated testing frees you up to focus on larger issues such as customer needs, functionality and improvements. Automated testing also reduces the cost and need for multiple code revisions, so over the course of time, the investment pays out. In addition, each time the source code is modified, the software tests can be repeated. Manually repeating these tests is costly and time-consuming, but automated tests can be run over and over again at no additional cost.

While automated testing has been considered essential for organizations, both large and small, to implement in order to deliver outstanding software and stay competitive in the industry, it can be tough to get started. Outlining an effective roadmap, building robust frameworks, choosing the right tools, and measuring the potential monetary impact that automation could have on your delivery lifecycle are all critical components of any successful automated testing strategy, but each step presents its own challenges and costs.
