Top 10 Functional Testing Tools
Imagine your favorite fashion store just launched its new e-commerce website, and you are so excited to shop your favorite dresses in the comfort of your home. You go ahead to sign up and add some of your favorite dresses to the cart, and boom, you could not find the checkout button. As a product owner or even users, we have all, at a point, faced the frustration of an application that does not do what it is expected to do.
Ensuring that software performs its intended functions is very important for a seamless user experience, and this is where functional testing comes into play. Now with the help of specialized tools, this process has become more efficient, making it easier to catch issues early and ensuring everything works as it should.
This article will examine some of the top functional testing tools and explore how they can help maintain high-quality software.
What is Functional Testing?
Every product or software has its own set of underwriting requirements, which defines the specifications that a software or product must possess to be considered successful and fully functional. These requirements outline what the software is supposed to do, how it should behave, and the standards it needs to achieve.
Functional testing is a type of software testing that focuses on verifying that a software application performs its intended functions correctly.
Examples of Functional Testing
1) Login Functionality: Let’s say you are testing the login functionality of an application, functional testing would involve entering valid login credentials to ensure that users can log in and perform any action they are supposed to. You would also want to test negative scenarios like when a user enters invalid credentials making sure the appropriate error messages and validations are applied.
2) Shopping Cart: Another example is testing the shopping cart of an e-commerce website, functional testing would involve making sure that users can add items to their cart, and update the items in their cart. Another important thing would be to check that the changes or updates made to the carts reflect the final price that would be paid by users.
