Understanding of Functional Testing

In the process of software development, to ensure the application functionality, functional testing is paramount. Functional testing is the type of testing process where testing engineers feed sample inputs and validate the application’s functionality as expected. It involves testing the application’s behavior, including API responses, and identifying the security vulnerabilities, servers, and overall application interactions.

It is a comprehensive testing method that includes unit testing, integration testing, system testing, and acceptance testing. Users are the primary resource for all businesses. Every product that is released on the market must satisfy the user's expectations. To achieve that, software development businesses never avoid functional testing. If the test case passes, they confidently move the application to the next phase of testing.

Some functional testing examples are,   

  • Ensuring the login page functions correctly by testing with negative inputs.
  • Verifying that the add-to-cart feature and the final payment process work accurately on an e-commerce website.
  • Checking data input fields for proper validation based on specified conditions.


Functional and Non-Functional Testing

Software testing is broadly classified into functional and non-functional testing. Both have equal contributions to ensure the quality of application.

Functional Testing

Functional testing focuses on testing the application’s key functions and features. It involves testing each individual module functionality under the specified requirements and verifying the test output as expected. This type of testing process assists to identify the bugs and defects that affected the software. To ensure the applications quality and reliability, conducting functional testing is required one. Also, it is called the black box testing as it focuses on application requirement rather than code.

Non-Functional Testing

Non-functional testing is related to the performance, security, stability, integrity and usability of software applications. It is primarily concerned with how the application performs under different scenarios. It helps to identify the complexity in the application performance and ensures that the application meets the user's expectations.

Manual Functional Testing vs Automated Functional Testing

Manual testing requires manual intervention to create and execute the test case. It requires a team of resources, which is cost-effective for small projects. As the digital world expands, the requirement and development in the complexity of software applications increases. So, it is challenging for manual test engineers to identify every bottleneck in the software, and it consumes huge amounts of time.   Automated functional testing requires the specialized tool which continuously executes the test cases. If the organization works on large projects, it requires frequent updates and changes. In that case, an automation tool will be effective. Moreover, automation testing reduces the time, errors occur in testing, and resources as well.

“By 2027, 80% of enterprises will have integrated AI-augmented testing tools into their software engineering toolchain, which is a significant increase from approximately 15% in early 2023.” -Gartner

Manual vs Automated Functional Testing

Choosing an Automation Testing tool

There are some crucial factors that need to be considered when choosing an ideal automation testing tool. Robustness and reliable test results are mandatory considerations for software testing. Below are the more requirement considerations to make the right decision.

  • Identify your requirements: First, measure the scope of the project. Based on that, list down the specific requirements for your project. Consider factors such as project size, the type of testing (functional or non-functional), and budgets when choosing the automation testing tool.
  • Research and Analysis: Once the complete requirements are identified, conduct thorough research and analysis to find the ideal automation tool. Consider open-source, commercial, and custom frameworks available in the market. Select and evaluate the tool that best meets all your testing needs based on the project requirements.
  • Budget Consideration: Once the ideal automation tool is identified, prioritizing budget considerations becomes crucial. Choose a tool that not only fits within your budget constraints but also adds significant value to your project, ensuring a successful outcome for your business.
