20 Top Benefits Of Test Automation

In today’s modern era, organizations are finding it more difficult to control the quality of their online apps since technology is advancing every day. Unfortunately, testing is often overlooked due to the restricted time constraint in agile development and economic considerations.  Lack of adequate testing results in lower-quality end-products, longer delivery times, unsatisfactory personalized service, and more expenses. 

An unanticipated test management approach, a development delay, or overestimating the work required to create a test case are examples of such concerns. Without a doubt, the test engineers aim to detect faults or problems before the product is released. However, the harsh reality is that you can’t capture every bug! 

So, after your move to production, you release a short repair, and that’s when regression testing kicks in. Regression testing takes a long time but is necessary for product reliability. In such cases, you will find yourself trapped in a vicious loop in which your deployment window continues to shrink. The question now is, how do we deal with situations like this? Test automation is the solution.


Overview Of Automation Testing

Automation testing is a kind of software testing that compares the actual result to the intended result. This may be accomplished via test scripts or any other automated testing tool. Automating repeated processes and other testing duties that are difficult to complete manually can be done through automating the testing process. Scripting of test cases should begin when the application is stable and frequent changes are not expected for greater automation ROI and to prevent any rework.


20 Test Automation Benefits

Since we have covered the basics, let’s look at the top twenty benefits of automated testing to help you decide if it is the correct decision for your company. Let’s get started! So dear readers,  let’s have a glance at the benefits of automated testing.


A Shorter Feedback Cycle

Feedback for newly built features might take a long without test automation. Test automation shortens the feedback loop and allows for speedier validation throughout product development stages. Test automation is particularly beneficial since it helps in the early detection of issues or errors during the development process, increasing the efficiency of the team.


Shift-Left Testing Is Done Better

We cannot omit to mention that one of the most important advantages of automated testing is Shift-left testing. It is a kind of continuous testing that states that the testing phase should be integrated into the SDLC (Software Development Life Cycle) from the requirements collecting phase onwards in order to catch errors early. Shift-left testing may help you enhance the quality of your product by allowing you to:

  • Resolve bugs quickly
  • Increase the test coverage
  • Automate monotonous activities and keep track of everything on the move.
  • Improve the developer-tester connection.

The main advantages of automated testing are that it can be done as soon as development begins, discovering errors or flaws early and allowing you to shift-left more effectively and quickly.

Run automation tests on user stories to verify that they are clear and to identify the validations and restrictions that every tester should be aware of. This strategy to test automation may assist you in detecting and eliminating early faults on your website.


Automation Saves Time

Your development team will spend less time validating newly generated features if you automate your testing approach. It also enhances communication with other departments that depend on the findings of these tests, such as marketing, design, or product owners. These formerly mentioned departments may readily review the automated test logs to see what’s going on.


Regression Testing

Manual testing takes time since testers must perform a set of comparable test cases over the same time period for each patch published in production to guarantee that the problem has been fixed. Every developer has struggled with regression testing. Repeating the same test consumes more time and reduces a tester’s overall efficiency. Manual regression testing tends to take a long time and results in the following problems:

  • The release cycle becomes rigid as a result of doing the complete regression.
  • Due to time restrictions, manual regression testing cannot be conducted properly every time the product is upgraded.
  • You will not be sure whether you conduct testing in the same manner, every time.

Automation testing is a great approach to undertaking regression testing because of this. Automation tests, as previously said, are similar to robots that never sleep. As a result, the time range for running the regression testing suite may always be extended. Furthermore, the time spent developing an automated test case is a one-time investment, which leads us to the second key advantage of automation testing.


Lower Operating Costs

Your organization will save money by employing an automated test environment since fewer resources would be used to test your product. The concept is that manual testing should be avoided. This may make a noteworthy impact throughout the duration of a project.

Installing and configuring an automated testing environment, of course, requires time and resources. You’re also likely to pay for a good test automation solution that can help you set up a solid test automation environment.


Increased Test Coverage

It is imperative to note that the amount of tests that you can validate while using manual testing is limited. Your team may spend more time developing new tests and uploading them to your automated test suite because of automation. This will expand your product’s test coverage. In addition to this, it would also ensure that more functionalities are thoroughly evaluated, consequently resulting in a higher-quality app.

Additionally, automated testing enables your development team to design more in-depth tests that cover a wider range of use cases. Long tests, which are often avoided during manual testing, maybe executed without supervision.


Test Suite Reusability

There might be a possibility that building an automated test suite might be difficult initially. But, once you have established your suite, it’s simple to reuse tests for different use cases or even other projects. You may quickly connect another project to your automated test suite, which is a big plus.


Less Human Resources 

A difficult manual test takes fewer personnel to conduct than automation testing. We require a test automation engineer that can build test scripts to automate our tests in order to apply the automation test script.


Enhances The Quality Of Manual Tests

The most widely acknowledged advantages of automated testing are the reduction of a manual tester’s unpleasant activity, allowing them more time and bandwidth to develop better test scenarios. Manual testing also provides a foundation for automated testing.

After you’ve completed manual testing, you may use test automation tools to double-check the results. Furthermore, the data supplied by automation test tools may assist testers in improving the quality of human test scripts. In recent years, these advantages of test automation have gained popularity with customers.


Testing Simultaneously Across Multiple Platforms

Cross-browser compatibility across numerous browsers, hardware, operating systems, networks, and mobile devices is critical when designing a website.

Browser compatibility testing necessitates the production of a large number of test cases. Manual testing of hundreds of browser + OS combinations may cause the product release process to be delayed, especially given the number of browser versions available on the market.

Among the many advantages of automated testing, we cannot overlook the fact that it enables testers to run tests on thousands of operating systems, browsers, and devices at the same time.

LambdaTest, for example, has an online Selenium Grid that allows you to perform automated browser testing on over 3000 actual browsers at the same time. LambdaTest provides you with increased test coverage and dramatically reduced built times. It will assist you in determining how effectively your web application renders across a range of browsers. LambdaTest allows you to automate cross-browser testing of your locally hosted web pages. A single test might potentially be conducted concurrently across several browser/OS setups.


Improved Time To Market

Test automation can also be used to continually test and verify newly generated functionalities. This shortens the feedback and testing process, allowing businesses to quickly get their goods to market.


Improves The Process Of Smoke Testing 

Smoke testing on a regular basis may help you prevent outages and is regarded as a best practice. Many companies, however, avoid it because they believe it would limit the tester’s capacity. This is why automated testing is seen as so important. The biggest advantages of automation testing are automatic test creation based on your random smoke test scenarios, and that’s all. You may now run smoke testing on a regular basis with ease.

Below-mentioned is some of the advantages of smoke testing:

  • Easy to test
  • Reduce the dangers of integration
  • Lowering the total risk
  • Early detection of flaws is critical
  • Enhances system performance
  • Recognize your progress.


Return On Investment

Manual testing, as we all know, takes a lot of time and resources. Automated tests that cover sensitive test cases almost always result in a positive return on investment. Such tests are not only used often throughout the project, but their components may also be utilized in other projects. Of course, return on investment takes time since it requires long-term planning, but bear in mind that automated testing is critical in large projects.


More Insights And Information

Automated testing delivers more information than manual testing when certain tests fail. Automated software testing not only displays you the memory contents, data tables, file contents, and other internal program states, but it also provides you insights into the application. This assists developers in determining what went wrong.

Automated testing is worth considering if you care about the quality of your project. It can both uncover flaws that people can’t and readily spot behavioral changes across platforms, operating systems, and browsers. It may assist you in determining if numerous actions in your app meet your requirements. 



Consider the following scenario: a new tester joins a project that has been under development for more than a year. He or she must be aware of all project needs and be able to execute them promptly. When used in conjunction with the BDD technique, automated testing makes things considerably simpler. New team members will be aware of which test cases have previously been covered by tests, while the scenarios will act as legible technical documentation.


Maximizing Test Coverage

Manual testing may aid in the creation of high-quality test cases, but achieving 100 percent test coverage for a complicated online application can be difficult. One of the most vital advantages of automated testing is that it may help you increase test coverage.

Automation testing tools may make testing easier by verifying that software, such as databases, online services, and user interfaces conform to business requirements. As a result, a web application’s total test coverage will increase.



Automated testing in conjunction with manual testing ensures that the project’s tests are accurate. Possible issues are found early in the project, which allows the QA team to concentrate on more accurate testing of new functionality rather than repeating the same routes.


Speeds-Up The Task Of Cross-Browser Testing

Manual cross-browser testing may provide a number of obstacles and issues. In manual testing, testers determine which browsers their web application must support initially. They run a single test on multiple browsers + OS settings after generating a checklist of all browsers to see how well their web development efforts are weighing in.

When you have a large audience to please, getting enough test coverage might seem impossible. Manual cross-browser testing may seem hard to prepare for every client inquiry, your website from legacy to the newest browser.

By running the same test cases many times on several browsers in parallel, automated cross-browser testing solutions like LambdaTest may save time and effort. So make use of them to get the most out of automated testing.


Easy execution of complex tests

Automation testing makes it simpler to execute bug-prone and complicated test scenarios. Test scenarios with repetitive procedures cause distraction and incorrect guarantees when manually tested.


Lastly, Run Your Tests 24/7

Manual testing has limitations. They can only be done for eight hours a day, five days a week, resulting in just forty hours a week committed to this critical work. People go home after eight hours of work, so the exams are put on hold.

On the other hand, automated testing has the benefit of being able to run at any time of day or night. You may receive the test report when you return to the office in the morning with them.

In the software industry, automation testing is becoming more common. It will offer several advantages if correctly executed. What chores are worth automating is also kept in mind. Tasks that are only done once should not be automated since the work required to automate them typically does not pay off. 

Testing is an important area where automation may help reduce SDLC deadlines. Automation testing solutions assist in overcoming the challenges of manual testing by lowering development costs, minimizing problems in the application, and improving product quality. That concludes the article. I hope you find it useful and educational.
