Why Test Automation is Key to Success

There are many benefits that come with Test Automation and, when implemented correctly, it can be a key factor in determining the success of a project/product.

Time (saving) Machine

The most obvious advantage of automating the testing of a product is the time saved when compared to carrying out the same tests manually. Assuming the tests have been set-up correctly, a computer will power through a larger set of tests in less time than it would take a human tester or team of testers.

Testing is significant both with regards to its importance in a project and also its size. Take something such as a service provided through a website, as the connected world grows ever bigger and more diverse, more and more potential platforms for the service are established that require testing. Automated testing can help save time when it is necessary to runs the same tests over a number of different hardware/software configurations.


Additionally, computers don’t need to eat, sleep, take breaks or even leave the office and can be set to complete tests overnight while employees are at home, something which simply can’t be achieved through manual testing. This can be extremely valuable when executing large sets of repetitive tests.

Completing more tests in less time can be a significant boost to a project in more ways than one. As per the common saying, we know that ‘Time is Money’ and that is especially true with modern software/service projects where a timely release is vitally important. Spending less time on testing through automation helps to ensure deadlines are met or even shorten the timeline of a project entirely, while not jeopardising the standards of the product (with the alternative being rushed or fewer tests).

Time is Money, but Money is also Money

Test Automation saves money too. The addition of robust and professional automated testing to any given project will help drive down costs and make the project’s budget go further.

There are savings to be made throughout the different stages of a product’s development and as a result of the inherent flexibility that comes with it, Automated Testing can be utilised effectively in a range of different project development lifecycles. In an agile development lifecycle, such as Scrum for example, regression testing is vitally important with constant changes being made to a product; this is just one area where Automated Testing can be implemented to save both money and time.

Ultimately, costs will be cut on three main fronts by producing quality results through rigorous testing; a well-tested product reduces risk, increases customer satisfaction and streamlines customer support.

That’s not all

When set up with the right instructions computers can perform tasks humans are just simply not capable of. This is especially true when it comes to testing; a computer is able to push the limits of software further than can be achieved through manual testing. For example, an online system may work perfectly with the ten users a human tester has created, but how about a hundred users, or a thousand, or a million? In this situation Test Automation can be used to create high numbers of user accounts in order to stress-test the system and accurately measure just how well it will cope with such a high volume of users; this would be incredibly time-consuming and repetitive if a human tester were to manually create and test all those users themselves.

Automated testing also helps to improve the efficiency of the testing process with less opportunity for human error; humans make mistakes, they get tired, they may even get bored of repeating a test or, for one reason or another, skip a test. Automation helps to remove the potentially problematic human element in testing thus lowering the chances of defects making it through to the final product.

With human testers no longer tied down with mundane repetitive testing, they are free to focus their efforts on other tasks like setting up more complex tests. These testers are likely to be happier too, and a happy workforce is hugely beneficial to a project’s success.


Automated Testing is fast, efficient, and should be considered an integral part of any modern software or service project. With a swift return on investment guaranteed, project managers looking to make their present or future products and services successful simply cannot afford not to overlook Test Automation. With Automated Testing the days of missing deadlines will be a thing of the past, only quality products and satisfied customers await.
