Top 30 Functional Testing Tools for Automation Testing
Success in functional testing is less about getting it right and more about avoiding mistakes.
The selection of the right functional testing tool is one of the crucial decisions you make for automation testing. Also, it is important for your overall software testing process. If it goes wrong, you pay hard. Because every functional testing tool has some limitations, you might overlook some hidden problems.
In selecting a tool, you have a set of selection constraints, which can be classified into hard and soft constraints. Hard constraints are fixed and must be satisfied in any case. These constraints include executing environments, programming languages, platforms, and framework used to build the application. The soft constraints include cost, maintainability, usability, schedule, level of programming and technical skills required. These constraints can be compromised or partially met.
While selecting the automation testing tool, you need to balance both the constraints based on the project requirements. However, it’s challenging to satisfy all the constraints with one functional testing tool.
To help you select the right functional testing tool, I’ve divided the blog into the following parts:
Challenges in Software Testing
There are many challenges in software testing for which QA teams look for testing tools to automate the functional testing. Because human error occurs more frequently with manual testing; automation testing maximizes efficiency and streamlines projects for success. Manual testing is also time-consuming, taking up more of your team’s attention during work hours. It is most practical when test cases run only a few times without frequent repetition.
We’ve helped one of our clients to automate their manual testing process. The company helps organizations to improve sales execution and streamline productivity by providing sales enablement software. They were facing both business and technical challenges while developing the software.
- The product had about 7000 manual tests which were increasing cost because of long testing cycles.
- Software modules were going into production with an insufficient level of regression testing. It created an unacceptable level of risk.
- Frequent releases caused versioning issues that ultimately affected wide range of customers.
- Frequent releases caused versioning issues
- Testing was depended on inconsistent existing test data because creating new test data was too time-consuming.
- Browser compatibility issues against different browsers like Internet Explorer (8,9,10,11), Firefox, Chrome, Safari & Opera and platforms (Windows & MAC).
- Complex enterprise systems that include multiple integrated technologies.
- Inefficiencies among testing resources with varying levels of technical/coding skills.
- Complex enterprise systems that included multiple integrated technologies.
We collaborated with our client’s development team at various levels to address these challenges. We took whole ownership of test automation – strategy, framework set, script development/maintenance, continuous integration, execution environment, and delivery.
We identified the right automation tools, framework & solution for various technologies. We came up with a cost-effective solution with open source tools.
- Achieved almost 50% cost reduction of the overall QA process
- Increased Test Coverage
- Reduced the testing cycle time from 10 days to just 2 days
- The automated functional testing tool has shortened the regression testing cycle and enabled public service release of product builds.
Criteria to Select the Right Functional Testing Tools
While selecting the functional testing tool, it’s important to create a list of requirements for better evaluation. Tool selection is often based on criteria that are less than optimal. So what are the right ones? Here are some key criteria which will help you to identify the best suited functional testing tool.
Programming Language and Development Environment
There are two approaches to work with automation tools in terms of programming language. Either use languages that are easy to learn, such as Ruby and Python or write the same programming language used by the programmers.
In Continuous Integration run, programmers need to fix the bug when the test is written in the same language as the production code when commit gets fail. Better yet, programmers can save time if the tool could run as a plug-in inside the developer’s integrated development environment (IDE).
If the tool runs outside the IDE and uses a different programming language, it is unlikely that the programmers will learn the new tool or do the work to support the tool when it reports “failures.”
Supported Platforms and Tagging
Make sure the tool supports all the platforms and levels the team support (web, mobile web, iOS native, Android native). If it doesn’t support most common platforms then the team need to cover that risk in some other way(s), which will eventually increase the cost. For such use cases, the tool can create a “page object” expressed as functions. The automated checks call those functions. It allows you to re-run the same test against a different page object because page objects are created at runtime.
Tagging is one way of tracking which tests run in which browsers. With tagging, you can instruct the tool to “run all tests for the edge browser full size,”. You can separate different tests like only back-end tests, only front-end tests, only tests that hit certain API, etc.
If the tool supports all the platforms, then it will need to track and run the subset that is supported. The ability to tag tests by feature can also be a powerful way to reduce risk while speeding up the delivery process.
Test reports document test results and their analysis. Therefore, select the functional testing tool whose dashboards and charts have a customizable degree of detail with respect to the intended audience (managers, customer, and developers).
Licensing and Support Costs
Consider the license cost as well as the costs that may pop up in the future (compatibility add-ons, support fees, etc.). The tool should do everything you need it to do without being a slow drain on the testing budget.
CI, DevOps Support
To avoid the automation delay, QA team run automation tool with CI process. Running the tests under CI creates a new requirement: The tests will need to be versioned with the code. That means the tool needs to run from the command line and produce output, which the CI system can interpret. For such requirements, your tool must be compatible with other CI tools.
Who writes the automation scripts in your company? Developers or test engineers? You need to select the functional testing tools based on your team’s culture. In many companies, developers write the automation scripts as they are more adept with programming. It saves the time of QA team while performing automation testing.
While selecting the functional testing tool, ask this question to yourself, “What are the critical bugs and where do they appear?”. You can get this answer with a bug tracker. That kind of research might find the majority of bugs in the business logic, the database layer, or the graphical user interface (GUI). For example, if the more important bugs are in the GUI, then test automation of the business logic through unit tests won’t add much value. It certainly won’t be the first place to start.

To help you compare the best functional testing tools, IT Central Station has ranked Top 10 functional testing tools based on hundreds of real user reviews.
Here is the color coding for different criteria used in the bar of each functional testing tool.
The total ranking of a product, represented by the bar length, is based on a weighted aggregate score. The score is calculated as follows: The product with the highest count in each area gets the highest available score. (20 points for Reviews; 16 points for Views, Comparisons, and Followers.) Every other product gets assigned points based on its total in proportion to the #1 product in that area. For example, if a product has 80% of the number of reviews compared to the product with the most reviews then the product’s score for reviews would be 20% (weighting factor) * 80% = 16. For Average Rating, the maximum score is 32 points awarded linearly based on our rating scale of 1-10. If a product has fewer than ten reviews, the point contribution for Average Rating is reduced (one-third reduction in points for products with 5-9 reviews; two-thirds reduction for products with fewer than five reviews). Reviews that are more than 24 months old, as well as those written by resellers, are completely excluded from the ranking algorithm.
