Overview of Functional Testing Tools
Functional Testing is usually done to verify whether the functionality of the application conforms to the requirements that were specified. It is usually tested in the black box testing environment, as it is not affected by the application source code. This testing usually checks whether the application components are behaving as intended. In this article, we will discuss the different types of functional testing tools.
Generally, a functional testing tool works in the following manner. We feed our input into the application to simulate user behavior. The result of our input is stored and recorded as output and then compared with our expected output. We usually have a status for these results as either “pass” or “fail” to help us with the results of our testing.
Functional testing comprises of inspecting the UI, the database, the APIs and more. We can test either manually or with the help of automation.
Different Functional testing tools
Let us look at a few of the top Functional testing tools in our industry today.
1. Test IO
Test IO runs functional tests in real-world circumstances, like real browsers and real devices, thus assuring us that our applications and websites work properly.
With Test IO, we can use the ability and insight of many testing geniuses and improve our web application quality. Many organizations that care about their customer reviews depend on Test IO for fast delivery and good quality applications.
- Test IO allows us to get an opinion from actual functional testers. They help by giving us additional, neutral judgment. Since they are fresh eyes looking into our project, they might catch errors that our team could not.
- We can choose to test from a wide range of real-world devices and platforms in all sorts of real-world conditions. By doing so, we can check the working of our application on all platforms.
- Test IO helps gives us faster releases of new versions.
Selenium is a functional testing tool that is an open-source tool and can be downloaded and utilized with absolutely no cost. It can be used to test web applications written in any number of languages like Java, C#, Perl, Python, and Ruby. It can easily be deployed on Windows, Linux and MAC systems.
Selenium has two fragments, namely the Selenium IDE and Selenium Web Driver. With Selenium IDE, we can record the working and play it to test the application. With Selenium Web driver, we can perform more complex testing and give in more commands for testing, those which are not possible in Selenium IDE.
- Selenium is easy and simple to use.
- It is an open-source tool.
- It takes on test scripts of several languages.
3. Coded UI Test
Coded UI Test is a Microsoft product, because of which we require the Microsoft Visual Studio and Machine to use it.
With the help of this tool, we can entirely automate our application tests and confirm their behavior and functionality. Since this is not an open-source tool, we must look at the price of the test tool and the licenses that come with it.
- Code UI Test is a simple tool, easy to configure.
- It makes sense of its data, including tables, very sensibly.
- It doesn’t use as much of scripting.
- It uses an XML based database manager.
- It provides handy support and documentation.
SoapUI is gaining popularity these days as an exceptional open-source functional testing tool. It can also be used for load, security and compliance testing. SoapUI works with service-oriented architectures and REST services. It is a cross-platform tool and can be used with NetBeans and Eclipse IDE. Other than testing, SoapUI can also be utilized for examination, development, and code mocks.
- SoapUI is an open-source tool, which is simple to use.
- It consists of functionalities like simple data-driven tests, etc.
- It can be used for technical purposes along with non-technical ones.
- It provides us with simple reporting tools, which can be imported to excel as well.
5. IBM Rational Functional Tester
IBM Rational Functional Tester is amongst the most sought-after tools for automated testing. This tool provides us with a defect management framework, which connects every test with its required document. The language of the test scripts can be either Java or Dotnet. We can also carry out functional and regression testing with Rational Functional Tester.
- It supports several applications, including PDF documents, Ajax and SAP applications.
- It offers us a trial of 30 days and great documentation to use this tool.
Watir is another automation tool that is open source and stands for web application testing in Ruby. It consists of further three parts, namely Watir Classic, Watir Spec, and Watir WebDriver. Watir Classic can use only the Internet Explorer web browser on Windows, whereas Watir WebDriver can use all the browsers. Watir WebDriver is based on Selenium and is a modern kind of Watir.
- Watir is open source and free for developers to use
- Tests scripts are simple to understand and maintain.
- Watir WebDriver can be used for any type of application in any technology.
- WebDriver aids multiple browsers.
7. Tricentis Tosca Testsuite
This is an efficient functional tool for end-to-end testing. It uses an agile methodology, which is an up-to-date methodology that is model-based.
It builds test cases that are written in a common, commercial language and not in any specific software language, making it easy for anyone to understand them. Thus, the test cases are produced in a smaller amount of time and can be utilized as either automated test scripts or manual tests. Its methodology is very efficient in taking care of tests with frequent changes during the course of the sprint cycles.
- Tricentis Tosca Testsuite is quite an efficient models based on an Agile method.
- It can undertake the most risks involved in the business.
- It used the DB Expert module very effortlessly.
- It can be looked after by non-technical users without any difficulty.
- It has admirable UI and graphic illustrations.
- It can be utilized on various platforms.
The main objective of Functional testing is to ensure that our system is working correctly in accordance with the requirement specification. We can use any of the many tools mentioned here to achieve this objective. The choice of the tool remains upon our requirements and needs.
