Functional Testing vs Automated Testing

This article is an introduction to functional testing and automation testing, with definitions, pros and cons, and other details.

Functional testing and automated testing are both important aspects of software testing, and each has unique advantages and scenarios. Combining the two can improve the efficiency and quality of testing, as well as reduce testing costs. This article will discuss the definitions, strengths, and weaknesses of both and the differences between them to help you quickly understand testing.

What is Functional Testing?

Functional testing is a type of testing that verifies if each function of the application runs as specified. This type of testing involves only black-box testing and is not concerned with the source code of the application. Each function of the software application is tested by providing a set of different data inputs and verifying whether the output results match the expected results.

Automated Functional testing is a technique that uses specific code to automatically execute test cases. There are various tools available to perform automated function testing, which will be discussed later in this article.

The Pros and Cons of Function Testing

This type of testing is designed to ensure that the software is working as intended and that all of its features and functions are functioning correctly. Here are some advantages and disadvantages of function testing:


  • Enhances software quality: Functional testing helps to ensure that the software is working as intended and meets the functional requirements specified in the project documentation. This can improve software quality and help prevent issues such as crashes, errors, and security vulnerabilities.
  • Reduces business risks: Functional testing can help to reduce the risk of software failures, which can have a significant impact on the business. By identifying and addressing defects early in the development process, Functional testing can help to mitigate these risks.
  • Improves customer satisfaction: When software is tested using function testing, it is more likely to meet customer expectations and function correctly. This can lead to higher customer satisfaction and improved business outcomes.


  • Limited testing scope: Functional testing is focused on evaluating the software based on its functional requirements. This means that it may not catch issues related to performance, scalability, and other non-functional requirements.
  • Time-consuming: Functional testing can be time-consuming, especially for large or complex software applications. This can impact development timelines and project budgets.
  • Requires detailed documentation: In order to conduct Functional testing effectively, detailed project documentation is required. This can be time-consuming to create and maintain and may require additional resources.

Overall, Functional testing is an important component of software development that can help to ensure that software meets functional requirements and is of high quality. However, this type of testing requires human intervention and is usually carried out by testers.

What is Automated Testing

Automated testing is a testing method that uses software tools and scripts to perform testing activities. In automated testing, testers write test scripts that can automatically execute test cases and generate test reports. This testing method is faster, more accurate, and more reliable than manual testing, which helps testers save a lot of time and effort while improving the efficiency and quality of testing. Automated testing is usually applied to testing scenarios with high repeatability, long duration, and difficult manual coverage, such as regression testing, performance testing, etc.

The Difference Between Functional Testing and Automated Testing

The main difference between functional testing and automated testing is that functional testing is a manual process that requires human intervention, while automated testing is carried out using automated tools and scripts. While functional testing is time-consuming and requires a lot of effort, it is essential to ensure that the application behaves as expected. Automated testing, on the other hand, is faster and more efficient but requires technical skills to create and maintain automation scripts.

In summary, functional testing is a manual process that involves human intervention to test the application's functionality against the functional requirements, while automated testing involves the use of automated tools and scripts to test the application's functionality. Both types of testing are essential to ensure that the application meets the required quality standards.
