Testing evaluates and verifies that a software application does what it’s supposed to do. There are various benefits of testing an application. They include detecting bugs, improving performance, and reducing the development costs of the application.

Most developers add better features during the testing process to improve customer satisfaction. Security is another important point as to why testing is usually performed. Before we dive into the advantages of automated testing over manual testing, let’s first discuss what each means.

Automated Testing Over Manual Testing

Automated testing refers to any solution that makes it possible to run your tests without human participation. Traditionally testing process has been done manually which required a long time, was error-prone, and very expensive. Automated testing works with the help of AI as it allows machines to write test scripts and codes themselves.

There are a few factors to consider before deciding whether the test needs to be automated or not. For instance, the tests that require constant testing or are repetitive using automated testing would be a reasonable solution. Manual testing however can be used for constantly changing and one-off or ad-hoc tests. The purpose of this testing process is still the same as that of the automated testing process. The manual testing process is the most primitive technique of all the testing types.

Here are the advantages of automated testing over manual testing

It saves time and money

The testing process is usually a continuous process, and every time the code is usually modified. It’s then tested across various configurations, user journeys, and operating systems. Testing all these processes manually will require enormous effort, and it’s costly. The cost and the time spent on these applications increase over time due to the owing expansion of the applications.

With automated testing, you can run tests repeatedly at no additional cost. Unlike the routine manual testing that takes hours and days, with automated testing, you can run tests 24/7. This means that there is faster delivery of functionalities, and the initial cost of the setup is usually low. Consequently, the more the automation coverage, the higher the return on investment.

Improved accuracy

With manual testing, the accuracy of different functionalities depends on the effectiveness of the testers involved in the process. If one of the testers makes a mistake in one of the stages, there might be a big problem with the end product. As a result, the company is likely to incur costs trying to rectify that problem.

There is improved accuracy with the automation testing because most of the tasks are performed using automated tools. That means that the tester’s dependency on the parameters to be used is removed. Due to the high precision of the tools used, the same expected results are reproduced without errors. Human biases are usually eliminated, all steps are executed accurately without fail, and the expected reports are produced.

Increased test coverage

In manual testing, the extent of the coverage mainly depends on the amount of work that the testers can do within the allocated time. With most large enterprises growing rapidly due to technology, there is a need for large teams, and a significant amount of time will be taken to carry out end-to-end testing.

Just imagine how long it will take to write the application’s code for the whole enterprise. Automated testing increases the test coverage in various ways. With just a few clicks of a button, many tasks can be performed and results produced.

You can test applications of any size, especially where no code is required. As a result, you will cover more features across the heterogeneous applications and their configurations. That’s what is usually referred to as enhanced test coverage.

Continuous testing is easily achieved.

Continuous Testing Is Easily Achieved.

Most software testing processes are completed better if the process is carried out continuously. This refers to the uninterrupted running of the test cases to get rapid feedback on the risks associated with the business.

With manual testing, this is almost impossible. As a result, there is delayed feedback on the risks likely to affect the business. Continuous testing is an integral part of automated testing.

It enables all the teams in the software testing process to work effectively and in cohesion. They can easily share their data during the testing process with other team members. Consequently, you will be able to test the application quickly and get the needed results rapidly.

It facilitates reusability

Nothing amazes most software testers like the ability of the automated tools to carry out the reusability process. Some of the testing processes like regression usually take a lot of time as there are a lot of details that need to be analyzed. For most testers, writing scripts now and then is a nightmare that most of them won’t even sneeze.

The reusable features of the automation testing process allow the reusability of the once-used codes. Instead of creating so many things, you just need a chance to create test scripts and learn and then keep on reusing them from time to time. That’s what you need in a different stage of the work.

Faster feedback

Instant feedback is a significant issue when testing processes using manual processes. This issue determines the next solution that the testers will struggle to win even if the team has inadequate resources. This means that you can easily fix the existing bugs to create high and excellent customer experiences instead of walking around.

With automated testing, there is great and instant feedback. And this helps to get wind of what’s going on in the market for you to adjust your application’s features. That also means less downtime will be compared to the other firm using the manual testing processes. Some of the automation software is pre-build and waiting for payment.

Security and scalability

There is less likelihood that information is safe in the hands of all testers in the manual testing process. They are human beings, and so all of them are prone to errors. There must be effective security for the testing to be effective, and all testing processes should be scalable.

Scalability ensures that more hands are added to the testing process in the manual process. With automated testing, the quality of the data created is usually high because of the applied security procedures.

In this case, you only make a test database when you are required to use it in the testing process. Still, it’s possible to scale in minutes with automated testing. That means you are adding more test executors to the process.


The testing process is crucial for every software application in all types of enterprises. It helps to detect bugs early and ensure that more features are added to the application to meet the customers’ demands. Testing can broadly be classified as either automated or manual. Automated testing has lots of benefits when compared to manual testing. The points mentioned above will help you understand the advantages of automated testing over manual testing.
