Why is automated API testing useful these days?

When you see the word automation, it means to ease human work with the help of software and tools. 

• In the coming years, automation testing will cover 80% of the test coverage of any application in a shorter time means automated testing helps to test large and many test cases very easily and quickly.
• It allows parallel execution and helps in reducing the number of errors that could be generated by humans.
• It saves the time required to test the applications manually and thus saves the overall cost of any project.
• Testers don’t have to worry about the part of the application that requires retesting.
• Helps in identifying defects or bugs at an early phase of development without having any access to the User interface.
