In the present digital world, quality and speed have become an important aspect to measure the success of applications. Considering these, enterprises are striving to deliver applications that are meeting both customer and business requirements. To ensure this, functional testing practice is very needful. And, this testing practice can be made even more efficient when it is practiced with the best functional testing tools. Before planning to choose the right automation tool for functional testing, testing teams need to understand the leading tools which can achieve the best results for the present and future business years 2020-2021.

Enterprises across the globe are effectively increasing their application delivery speed to compete with the growing market requirements. If the released application is as per the requirements, then it is advantageous and even assures profit for enterprises. But, if the application fails to respond with the expected functionalities, then it will be a complete drawback and this directly affects the business. To ensure the developed application is functioning as per the specified requirements, it is crucial to perform functional testing.

Functional testing is one of the very important software testing practices. This method helps in verifying whether the developed application is matching with the requirements that are specified by the client. This process can be more effective when it is practiced with automation tools. Since we have completed half of 2020 and moving close to 2021, teams need to identify the automation tools that can be profitable for the year 2020-2021.

Top 10 Functional Testing Tools in 2020-2021
