Various tools can help you test the functionality, performance and regression of a software with bare minimum interaction from your end. Automation testing is a crucial step that ensures that a software runs smoothly without any hiccups before releasing it for production.

What Is an Open Source Automation Tool?

As the name suggests, an open-source automation tool is one whose source code is available for free, and you can also modify the original design of the code. These tools do not have a commercial license, unlike the licensed ones.

Specific open-source tools service certain functions. For example, you cannot use the same device you use to test the software to check the web application or perform a load test.

Hence, it is always best to know which tool serves the best purpose for your task.

List Of 10 Best Open Source Automation Tools

Most students who depend on academic help online & mechanical engineering assignment writing services are not aware of the correct automation tools to help them with their tasks. 

 As software testing can get pretty repetitive, these resources ensure error-free automatic testing to increase the software’s speed, quality, and efficiency. On that note, let’s look at the ten standard tools you’re most likely to come across.

1. Robotium

The Robotium open-source test framework makes it easier to conduct automatic UI test cases for Android mobile applications. With its help, you can, write function, system and application test scenarios. In addition, you can run these tests on a mobile device as well as an emulator.

Some of its other benefits are:

  • It easily integrates into Maven and ANT
  • It is easy to write
  • The codes are short
  • Can make automatic decisions
  • Conducts fast test execution
  • Finds views automatically

2. Selenium

The Selenium testing tool helps you to automate tests across web application browsers. It is a beneficial tool that can reduce the execution time and supports different operating systems such as Windows, Linux and Mac. In addition, it also supports various scripting languages such as Java, Ruby, Python.

If you wish to conduct regression and exploratory testing, Selenium is your perfect tool. However, it is best to keep in mind that you cannot use this tool to test desktop-based applications or conduct image testing.

3. Katalon Studio

Katalon studio was first released to the public in 2016 and has become a popular open-source automation tool that supports web and mobile applications and API testing. Its powerful recording ability helps you to store all UI elements to maximise stability. Furthermore, it also provides a codeless experience for beginners.

Some other notable features are:

  • Provides seamless integration with SDLC management and CI/CD pipeline
  • You can use the Katalon store for additional features
  • Enables cross-function operations for product developmental teams

4. Appium

Dan Cuellar developed Appium in 2011, and it is still trending as one of the best mobile application testing tools under Mobile Automation Testing Technology. You can use this open-source tool for automatic testing of native, hybrid and web applications. 

While you can use Appium for both Android and iOS devices, you cannot use it for older android devices. 

5. Watir

Watir is an acronym for Web Application Testing In Ruby that helps in automating web applications regardless of the language. It interacts with the web the same way any human would do, such as filling forms, clicking on links and validating texts. 

6. Sikuli

Sikuli, introduced by RaimundHocke in 2011, is an open-source testing tool that tests the GUI using image recognition methods. This is the perfect tool to use when you do not have access to an application’s internal source code. Sikuli can help you automate anything that you see on screen. Furthermore, it is handy if you wish to automate non-web-based desktop applications.

7. JUnit

As you might have figured out from the name itself, JUnit is an open-source tool that helps you to perform unit tests for a small unit of code. It is possible to integrate JUnit with Ant and Maven. However, it cannot do dependency tests. Otherwise, it is an excellent tool that provides assertations class to check expected results.

8. JMeter

JMeter is a popular open-source automation testing tool to conduct load and performance tests on websites. It supports Record and Playback feature and runs on multiple platforms. Even though it isn’t very suitable for desktop applications, you can analyse the performance of various services using this software.

9. Cucumber

The Cucumber testing framework has its basis in Behaviour Driven Development, where it defines the application behaviour using “Gherkin”. It supports languages like Java, Python and DotNet, and is available as a plugin in eclipse software. However, one downside to it is that it supports only web applications.

10. Testerum

Testerum helps you perform various tasks, such as test your REST API, execute all tests in a CI/CD environment, test Web applications, create any custom integration you want, and many more. The tests are visioned with the code, and you can easily find its details for better understanding.

Benefits Of Using Open Source Automation Tools

Now that you’re up-to-date with the best open source automation tools that you can find, you need to understand why it is necessary to use these resources. 

During the developmental stages, you would need to conduct tests pretty frequently to ensure that it is high-quality. For example, every time you modify a source code, you need to follow it up with a trial. 

Hence, the entire process can become highly repetitive, increasing the chances of human error. As a result, even the most expert developers prefer automation testing tools to help them work more efficiently. These tools allow you to:

1. Save time and money

Manual testing takes up considerable time and is pretty expensive to repeat multiple times. However, with the help of automatic tools, you can repeat the tests multiple times at no additional cost. Furthermore, they are much faster and end up consuming less time.

2. Increase accuracy

Any tester is bound to make a mistake when they have to conduct tests multiple times. Unfortunately, human error can happen at any point and takes too much time to release the software to the public. Hence, it is always best to use automation tools that can perform each step with high accuracy. Furthermore, these tools also record the results of each stage, ensuring that you can always consult them later on.

3. Widen test coverage

Testers usually avoid conducting lengthy tests in the manual mode as it takes up a significant portion of their time and, in most cases, is impossible. However, automated software testing can run continuously unattended and execute thousands of complex tests that are impossible to cover manually.

Summing it up,

Open source automation tools have been in great demand due to their immense help in running smooth tests. It is a faster process to attain feedback and eliminate the problems that usually occur during manual testing. However, it would help if you were careful that these tools are well-maintained and align with your testing needs. As long as you conduct thorough research and ensure that it meets all your requirements, there should be no trouble using them to make your tests run smoother.
