For you to make an informed choice, we've created this complete guide to functional testing tools. First, we'll discuss functional testing and why it's essential. Then, we'll compare some of the most popular functional testing tools on the market today. Finally, we'll share some tips on choosing the right tool for your needs.
So, whether you're just getting started with functional testing or a seasoned pro, this guide will give you the relevant information to choose the right functional testing tool for your project.
What is Functional Testing?
Functional testing is software testing that ensures that the software behaves as expected. This means verifying that the software functions correctly and meets the requirements specified by the client or customer.
Testers can use this testing to test any software, including web applications, mobile apps, desktop applications, etc.
Functional testing is essential because it helps ensure that the software works as intended and meets the users' needs.
By verifying that the software functions correctly, functional testing can help to prevent bugs and errors from occurring in the final product. This can save time and money by avoiding potential problems down the road.
In addition, functional testing can also help improve the user experience by ensuring that the software is easy to use and meets their needs. By testing the software's functionality, you can make sure that users will be able to use it as intended and will not run into any problems.
Choosing the Right Functional Testing Tool
Functional testing tools are essential for ensuring that software works as expected. But with different options on the market, how do you know which one is right for your project?
To choose the best functional testing tool, you'll need to consider a few key factors such as:
Supported Platforms and Tagging
Functional testing tools usually support a variety of platforms such as Windows, macOS, and Linux. Some tools also support mobile platforms such as iOS and Android.
When choosing a functional testing tool, you'll need to ensure that it supports the platform you're working on.
In addition, you'll need to consider how the tool handles tagging. Tagging is a way of labeling tests to be run together. For example, you might tag all tests for a login system with "login."
Tagging is important because it allows you to run only the tests you need. This can save you a lot of time, especially if you have an extensive test suite.
Programming Language and Development Environment
The selection of programming language and development environment can significantly impact the team's efficiency.
Some languages are more suitable for certain types of tests than others. For example, C++ is often used for low-level system testing, while Java is used for application testing.
You should also take into consideration the development environment. For example, if the team is using a continuous integration (CI) system, then the tool should be able to integrate with it. If the team uses a specific IDE, the tool should be compatible with it.
Licensing and Support Costs
You should consider the costs of the tool in view of the overall cost of quality. For example, a production-level bug can cost orders of magnitude more than the tool's price. Also, compare the features offered in each tool and make sure you are getting what you need for your project.
There are several types of licenses
2. Floating user-based
3. Named user
4. Concurrent User
5. Seat license
6. Site license
You will need to consider the support costs for open-source tools if any. Most of the commercial tools offer some supporting plan. Ensure you understand what the support plan includes and the costs.
The tool's user interface (UI) should be intuitive and easy to use. The UI is important because both developers and testers will use it. If the UI is not intuitive, learning and using the tool will take longer.
Also, make sure the UI supports all the features you need. For example, if you need to record tests, make sure the UI has a recorder.
If you need to create data-driven tests, make sure the UI has a way to create and manage data sources.
This is an absolute must-have. Your testing tool should let you categorize bugs by type (e.g., cosmetic, functional, usability) and severity (e.g., low, medium, high). It should also let you assign a priority to each bug so that you know which bugs to tackle first.
CI, DevOps Support
If you are using Continuous Integration (CI), make sure the tool can run in CI. Most popular CI tools, such as Jenkins and TeamCity, have plugins for popular functional testing tools.
Also, make sure you can integrate the tool with your development environment. For example, if you use Eclipse, make sure the tool has an Eclipse plugin.
Functional testing tools vary in the technical knowledge required to use them. Most modern test automation tools have evolved from code-based to scriptless, or at least codeless, thanks to the proliferation of drag-and-drop features.
But if you need complete control over every aspect of your tests and are open to learning a new language, code-based solutions may work better for you.
Evaluate your team’s skill set and experience with programming languages to ensure your testing tool is the best fit for their skills.
Also, make sure the tool will fit into your development process. For example, if you are using Agile, make sure the tool can be used in an Agile environment.
All these factors contribute significantly to choosing the right functional testing tool. Therefore, consider all these factors before making a decision.
Challenges in Software Testing
If the software didn't have bugs, the world would be more straightforward. But software can be complex, and sometimes developers miss things. Defects are found all the time, but some common problems tend to be more frequent than others.
Here are some of the most everyday challenges in software testing and how you can use functional testing tools to solve them:
It's hard to know what's going on in your application if you don't have visibility into it. Functional testing tools can help by letting you see what's going on in your apps as you test them. So instead of guessing what might be happening, you can take a look for yourself and establish whether there is a problem or not.
Time is always an issue when it comes to software testing. Of course, you want to find problems before they get out into production, but you also want to get your products out of the door quickly to start making money for your company. Functional testing tools allow you to automate parts of your tests to run overnight while you sleep, freeing up worker time during the day so that everyone can concentrate on other things.
The cost is always a significant factor when it comes to software testing. Of course, you want to find problems before they cause expensive production issues, but you also don't want to spend too much money on tools and resources. Functional testing tools can help by providing a cost-effective way to test your applications thoroughly.
Change is constant in the world of software development. New features are constantly being added, and new technologies are always emerging. This makes keeping up with changes complex when ensuring that your functional tests are still relevant. Functional testing tools can help by providing an easy way to change your test cases as your application changes.
Life is inevitably complex in the world of software development. As applications get more complex, it becomes harder to test them thoroughly. Functional testing tools can help by breaking down complex applications into smaller pieces that are easier to test.
Functional testing tools Overview
Functional testing tools let you test your software at the user interface level. They interact with your application as a real user would by using menus, windows, dialog boxes, and dialog controls.
Functional testing tools may also include navigational tests that check whether links to other pages and screens in your application are functioning correctly.
Most functional testing tools offer two types of tests: record-and-replay and keyword-driven. You can use both types on different platforms and for different technologies, including Web services, Java,.NET and Windows applications, Web browsers, and SAP.
Record-and-replay tests are the easiest to create. You can use them if the test flow doesn't require a lot of logic or decision-making. The record-and-replay process involves three steps:
a) Recording actions performed on the System Under Test (SUT)
b) Storing those actions in a script.
c) And replaying the script to verify that the SUT is functioning correctly.
This involves creating a library of keywords that map to functionality in your SUT. Then you use these keywords to create high-level test scripts that are easy to understand and maintain.
Then, in the functional testing of a new feature, you simply add the appropriate keywords to your script. This is an excellent time-saving method, mainly if you're working with a team of testers who are not all familiar with the code.
You can use this testing on any platform or technology. However, it's particularly well suited for testing Web applications because it allows you to create test scripts without writing code.
