Automated Testing vs Unit Testing


Technologies are getting more advanced; hence, software development projects are not left behind and tend to chase an inevitable path of chaos.

In this software industry, the mass number of software testing methodologies and tools with the guidance of test automation services delivering high-quality products and efficient services is significant. 

Evaluating the application or software is essential to ensure bug-free mistakes and unmet requirements. 

It is crucial to learn which verification process works well in all features in a software development cycle. The confusion between unit testing and automated testing is still ongoing. 

Automation Testing and Unit Testing Description  

Before we dive in, let’s describe these two testing processes of software and application. 

First, automation testing is a software testing process that executes special automated testing software tools to perform a test case collection. Their primary purpose is to meet requirements and review software and other tech product quality. 

Unit testing tests the method, function, and procedure of programming code. Thus, the name unit testing is clear. Often, a unit is an individual function, but it can also be a whole module. 

Therefore, automation testing includes several types of automated testing, while unit testing is a strategy method that primarily focuses on distinctive parts of code. 

Now, let’s take a closer look to define their differences and make a better understanding of their functions: 

Establishing Goal 

Therefore, automation testing includes several types of automated testing and focuses on the reliability of the flow and perseverance in meeting the requirements. It uses special software tools to verify code and execute tests and analyze the comparison of test results to expected results. 

Also, this testing process is primarily helpful to ensure the application is free of bugs and mistakes and performs its calculated functions. 

Meanwhile, Unit testing is a strategy method that primarily aims at the distinctive parts of code and fulfills the appropriate code quality. It means testing the particular pieces of software or assessing a tiny amount of the overall application. 

Moreover, it is a test where it creates a short script or part of code to verify the behavior of a specific unit to provide pass or fail results. 


Automation testing consists of writing scripts to check flows like purchase flow; when most of us try to buy a product via pick up, add to cart, and check out. The code contains a smaller unit for this flow to become achievable. 

Scripted sequences use running automation testing regardless of time. Automated testing requires direct investment in tools and setting up, which is quite expensive but worth it if initiated. This test undoubtedly has the advantage of boosting productivity and improving overall functionality. 

Unit testing usually requires developers to record failing unit tests, afterward writing code allowing them to change the application until the test passes. The unit test itself is a short script to verify the behavior of a specific unit allowing developers to locate potential loopholes and resolve their conformity to the designed specifications.  


Automation testing by QA or quality assurance automation specialists upgrades the accessible strategy of the test coverage on the project, starting from simple routine tasks to covering all the flows with test access if all the flows hand out their primary purpose. 

In every spot, automation testing assists stakeholders to improve a broader and better picture of the product quality, in which it is impossible to unit testing. 

Developers are responsible for unit testing. It helps them receive instant feedback on the functionality of their code to conceive whether it’s safe to move further or needs revision as the output is different from the expected one.

This test is designed for code with no external dependencies like calling the database or web services since it only focuses on specific behavior in a small system section. 


Automation testing has several advantages, including saving money and time by running repetitive tests for days, a massive increase in test coverage, and helping developers and testers to catch problems immediately.

 Aside from that, it improves accuracy due to performing a similar process precisely every time they do the execution and recording detailed results. Plus, QA team members and developers enhance their skill set and improve their morale.

Furthermore, unit testing also serves many advantages like reusable code, providing the opportunity to help assess performance, and reducing code complexity. Similar to automation, it saves money and time due to locating the bug quickly.

It encompasses the benefit of improving code coverage and better documentation. Unit testing ensures that all code meets the requirements and quality standards before deployment.


The good news is that a better choice is irrelevant since unit testing can complement automation testing techniques. Involving unit testing in automation testing is an excellent way to double-check that nothing is missed and overlooked.  

Either automated or unit testing, this type of testing can contribute to a company’s success. The option should gather individual needs or product requirements.
