Test automation
Test automation is the use of software separate from the software being tested to control the execution of tests and the comparison of actual outcomes with predicted outcomes. It’s a crucial part of modern software development, ensuring quality, accelerating release cycles, and reducing the risk of bugs impacting end-users.
By automating repetitive testing tasks, businesses can free up valuable developer time for more complex work, ultimately leading to faster development and higher-quality software.
