Automation Tools for Web Testing

Introduction to Automation Testing

Automation testing is a process of automating the execution of test cases. It can be used to regression testing and can also be used to generate test reports. There are various tools available for automation testing, but not all of them are created equal.
Various tools exist on the internet, and each of them possesses different combinations of features. Once you find the one that suits you get it. Let’s have a look at the top 10 automation testing tools list.

What are the Benefits of Automation Testing?

Automated testing can help improve the quality of your web applications by catching bugs and errors early on in the development process. Additionally, automated tests can be run more frequently and at a faster pace than manual testing, providing more comprehensive coverage of your codebase. Automated tests can also be written to specifically test for edge cases and corner conditions that may be difficult to replicate manually.
Automation testing helps developers to enhance the overall quality of applications. It also reduces the testing cost and makes it faster than the traditional one. Hence, the efficiency of testing gets maximized due to automation.
Overall, automated testing can save you time and money while helping to ensure the quality of your web applications.

– Selenium

Selenium is a web testing tool that automates the testing of web applications. It is an open source project that allows testers to write tests in any programming language they want. Selenium has become the de facto standard for web testing and is used by major organizations such as Google, Facebook, and Netflix.

Selenium can be used to test all kinds of web applications, including those written in Java, .NET, PHP, Python, and Ruby. It can also be used to test mobile applications. Selenium is a powerful tool that can be used to automate both simple and complex web tests.

Benefits with Selenium:

1. Open Source and comes free without licensing cost.
2. Multi-Language Support like C#, Java, Python, JavaScript, and so on.
3. Multi-Browser Support like Chrome, Firefox, IE, Safari, and so on.
4. Platform Support like Windows, Mac, Linux, and so on.
5. It can be used with multiple frameworks like TestNG, JUnit. There are different frameworks like Data Driven Framework, Keyword Driven Framework, Hybrid Framework, etc.
6. Multiple test scripts should be executed in parallel to reduce the test execution time. With the help of Selenium Grid, multiple scripts can be executed on remote machines.
7. Scripts can be reused since the same tests developed can be validated against multiple browsers.
8. Selenium test automation can be integrated with TestNG and Junit for managing test scripts and generating reports. Continuous Integration testing can be integrated with CI/CD tools like Jenkins, Maven, Docker, etc.
9. It reduces manual testing efforts by performing functional, regression, end-to-end, cross browser, smoke, sanity, acceptance, integration, and so on.
10. Since Selenium has been around for a long time, it has a huge community of helpful users. There are guides and documentation to help the testers solve the issues that they are met with.

Cucumber is one of the most popular open source automation tools for web testing. Cucumber is a tool that supports BDD (Behaviour Data-Driven). It acts as a bridge between a software engineer and business analyst, manual testers and automation tester, and developer and manual tester, as cucumber makes it easy to read and understand application flow.

In BDD, before a developer write a code, the first user writes test scenarios or acceptance tests as per the behavior of the system from the customer’s perspective for review and sign-off by product owners.

Benefits of Cucumber:

It involves business stakeholders who can easily read the code.
Main focus is an end-user experience.
Easy reuse of code in the test as simple test script architecture.
Easy to set up and execute.
Multi-language support like Java,.Net, Ruby, etc.
Works as a bridge between business and technical language.
Coding knowledge is not required to write a test.
Efficient tool.
