    In our previous blog, we have explained functional testing in detail. We have discussed functional testing along with types of functional testing. If you haven’t read that yet, click on the link for the detailed information.

    In this blog, we will get to know about Automation Testing and how it is different from Functional Testing. Those who are searching for the difference between Automation Testing & Functional Testing should read the entire content.

    We have written this content including our practical experience for both the testing types. Further, we are a well-established software testing company. While reading the content, if you have any doubts or queries, feel free to share.

    What is Functional Testing?

    We all are pretty aware that the functionalities of any application matter a lot. If we say, the functional approach acts as a backbone of the web and mobile application. With the great design, you can attract users but with smooth functions, you sustain them forever.

    So during functional testing, all the features and working ability of an application are tested thoroughly. The ultimate aim behind functional testing is to facilitate user accessibility.

    We all know, that users immediately reject complex applications, and hence testers make sure the easier accessibility of the app.

    Also, functional testing enhances the durability, reliability, and robustness of an application. How the application will perform at the user’s end, is also verified during this method of testing.

    Functional testing follows automation as well as the manual approach to testing. Everything cannot be checked through automation testing and hence manual testing is also involved in order to ensure the functionality of the software.

    Various types of functional testing include Unit Testing, Integration Testing, Smoke Testing, Sanity Testing, Regression Testing, and User Acceptance Testing. Detailed information about all these testing methods is explained in our previous blog.

    Why is Functional Testing Important?

    We are a renowned functional testing company in India and we are pretty well aware of its importance. Advantages of functional testing are:

    • Enhances user satisfaction: Through functional testing, all the processes of the software are properly verified, as a result of which the client becomes happy.
    • Delivers defect-free application: The maximum possible bugs are removed during the process of functional testing.
    • Reduces the risk associated with the software or application: Sometimes a small bug may create big issues in the future but with functional testing, all small and big bugs are fixed and hence risks are minimized.
    • Meets requirement shared by the user: During functional testing, the software is validated against the requirement shared by the client.
    • Ensures smooth functioning of the product: QA team minutely cross-checks all the related functions of the software.
    • Maintains security, safety, and reliability of the application: With functional testing, the reliability and security of the application are maintained.

    What is Automation Testing?

    Automation Testing is an approach to qualitative analysis in which the software is validated against the requirement using automation tools.

    A script is written in order to check the application developed by the developer. Multiple environments are set up and the functions of the application are checked.

    There are numerous automation tools are available that are used by software testing companies to check the performance of the software. With the foundation of Automation Testing, the manual effort for testing is reduced a lot.

    There was an era when testing revolves around manual processes. The manual testing process took too much time and the assurance of the product is not as accurate as automation testing.

    In the present time, automation has acquired the testing world, and any application does not get approval without automation testing.

    Why is Automation Testing Important?

    Automation Testing has given a new vision to software testing companies. The testing process that takes 7 days through a manual approach now can be done within a few hours only. This is only because of the automation testing method.

    Advantages of Automation Testing include

    Detailed Reporting: Automation testing has the provision of report generation. All the tools have this inbuilt feature and once the testing completes, a detailed report is generated by the automation tool. It keeps the track of the entire process, bugs, functions, etc.

    Fast Bug Detection Process: Automation testing highlights the bugs frequently as compared to manual testing. Fast bug detection, increases the pace of the overall testing and development process.

    Offers Simple Testing: With automation testing, not much manual effort is needed. Hence testers are not required to run behind each and every process during automation testing.

    Reduced Manual Effort: Automation testing runs on the scripts and there is no need to put the testing combinations manually. Hence the process does not need human intervention.

    Cost and Time Saving: As we have seen, the overall testing process takes minimal time as a result of which time and cost both get saved. And all QA companies in India always do their best to save time and cost.

    Final Words

    So, this is about functional testing and automation testing. By reading the above content, you will be able to analyze the difference between automation testing and functional testing. Both are the types of testing, and only their working process is slightly different.

    What is difference between functional and manual testing?

    Functional testing defines what to test (ensuring features work as intended), while manual testing is the how (human testers physically interact with the software to find bugs and usability issues). They work together: functional testing identifies functionalities to test, and manual testing validates them through hands-on exploration.

    What is the difference between functional and API testing?

    Functional testing validates an application's overall user experience (think testing a car you drive), while API testing focuses on the communication layer between software components (think testing the car's engine before installation). They work together to ensure both a smooth user experience and reliable software functionality.

    Is selenium a functional test automation?

    Yes, Selenium can be used for functional test automation. It allows you to write scripts that simulate user actions like clicking buttons, entering text, and navigating through web applications. These automated scripts can then be used to verify the expected behavior of the application, making it a valuable tool for functional testing. While Selenium itself doesn't guarantee purely functional testing, it provides the foundation for automating actions that can be used to assess functionalities. Integrating Selenium with other frameworks or tools can further enhance its capabilities for comprehensive functional test automation.
