20 Test Automation Case Studies Demonstrating Business Impact

QA teams struggle with slow, manual testing—resulting in higher costs, longer development cycles, and customer dissatisfaction. Transitioning to automated QA testing is the top priority in the software testing environment.

To help decision-makers assess the impact of test automation, we analyze 20 case studies highlighting real-world transformations.

Test automation case studies by industry

A common characteristic we noticed in 50% of the case studies mentioned is that the companies initially used or experimented with Selenium, an open-source tool for test automation. However, companies opted for a different test automation provider because they found Selenium to be either too complicated to use or inefficient for their needs. 

What are the common problems in these case studies?

Bad coding

According to our observation, developers skip or reduce testing if a company has a hard-to-use or ineffective testing system because it increases the effort required without a clear benefit. An ineffective testing system can harm a company substantially by allowing bugs to reach later development stages, which can result in the following:

  • Higher cost of bug fixing
  • Lower product quality  
  • Loss of customers

Automation testing effect: Test automation can reduce the effort required by manual testing. It is reported that in 46% of the cases where test automation was implemented, 50% or more of the manual testing was replaced. Additionally, 55% of companies seeking test automation mention quality improvement as their main strategic driver. 

Slow testing

Slow testing is a significant hurdle in the age of agile development and CI/CD. It is estimated that 35% of the testing cycle is spent on manual testing. Slow testing increases the development time and reduces the feedback available for each build of a design. 

Automation testing effect: Test automation can significantly increase the number of tests that can be run in a time period. 30% of companies that are pursuing test automation indicate time to market as their main driver. 

Workforce with different skill levels 

Each company’s testing workforce is different. Within a team, skill levels can drastically differ among members; some can be professional testers with advanced programming knowledge, while others might not know how to program.

Automation testing effect: Test automation tools can provide no/low-code solutions that can benefit non-technical users.
