Automated Testing

Automated testing is a great option for repetitive tests such as regression and functional testing but not useable for testing methods such as discovery and usability testing that requires a human to do the work. If used correctly, automated testing can save a lot of time and therefore money. If used incorrectly, it could end up costing more than manual testing.

Certain requirements that the testing process to be automated must meet are that it is repeatable, determinant, and non-opinionated. The first requirement, repeatable, means that it must be ran more than once, or else there would be no reason to automate it. Repeatable tests have three steps: set up the tests with data and environment, execute the function and measure the result, and clean up the data and environment after testing. The second requirement, determinant, means that the outcome will be the same every time the function runs with the same input. For example, when inputted 1 and 2 to an addition function, the outcome 3 must be produced every time it is ran with those inputs. The third requirement, non-opinionated means that there must be a concrete answer. You cannot automate opinionated feedback.

Now that we talked about the requirements of automated testing, now we will discuss the three steps of automated testing: prepare, take action, and report results. In the first step, prepare, you set up the data and test environment where the tests occur. This will require either manipulation of the data or putting the program in a certain state, or both. The second step, take action, the driver will run the tests. This will happen by calling the code directly, or accessing a programs api or user interface. And lastly, report results. The automated system will record and report the results from the test.

When used properly, test automation can save money and time and provide quality test results.
