Test Automation Tools

We have seen in the early 2000’s most of the projects used to follow up the Waterfall model for software development. Due to the nature of the development lifecycle, time required for project testing is considerable , some projects may last till a year or even more, this impact on the test phase efficiency considering efforts on the regression testing.

But later, the revolution took place in the field of testing & that changed the whole testing community, that revolution is called “Automation”.

In this blog we are going to see what is test automation & what are the various modern days technologies used in the automation.

Automation testing is nothing but taking a repeatable manual process performed by a developer or tester and using a tool to automate the process. Automation helps you to accelerate running through several test scenarios to check that the results produced by specific actions or lines of code match the expected results. If not, it raises an exception to let you know that something went wrong.

This approach is useful to speeds up the time to test since you are using a scripted process that evaluates if the software developed actually meets your requirements

Following are the few widely used tools for automation testing.

  • Selenium.
  • Cypress.
  • Appium
  • Postman
  • QTP
  • Squish

Selenium vs Cypress: When to use which for Test Automation :

Although Selenium and Cypress are both designed to automate browsers for testing purposes, they differ considerably in terms of architecture and performance. A key difference is that Cypress as a tool is ideal for introducing developers to test automation rather than just a replacement for Selenium. This is why Cypress is among the fastest-growing automation tools in the world. On the other hand, Selenium is a more general-purpose tool targeted at a broader audience

Cypress is preferred over Selenium when we need:

  • Single Framework for Component, API, End to End, Visual, Accessibility, Performance testing
    .
  • Video recording capability of test execution
  • Single Programming language across development (Front end) and Automation

Selenium is preferred over Cypress when we need:

  • When we need flexibility in terms of choosing test script language. Cypress supports on JavaScript’s, while Selenium supports several languages like Java, Python, JavaScript, C#, etc.
  • When we need to run a test case on different browsers simultaneously then Selenium Grid works the best, since Cypress cannot be used to drive two browsers at the same time.
  • Cross browser testing at scale becomes easy with Selenium. Cypress does not support browsers like Safari, which restricts the cross browser testing support, when compared to Selenium.

Appium vs Selenium: When to use which for Test Automation:

Appium is an automation tool that was built for testing all types of applications whether mobile, web or hybrid applications. It is open-source software that was built using the C# programming language. Whereas Selenium is an open-source browser automation tool and it contains a large number of inbuilt libraries for web application testing. It is capable of automating nearly all the web browsers like Chrome, Brave, Firefox, etc.

Appium is preferred over Selenium when we need:

  • When we need to automate all types of web applications along with the mobile app, Appium can
    automate mobile applications.
  • Appium supports the Android operating system
  • We can use appium even if we don’t have any knowledge of programming language It does not require coding knowledge for its operation

Selenium is preferred over Appium when we need:

  • When we want to perform automation testing on a different operating system. Selenium is portable and supports different operating systems like Unix, Windows, Linux, Mac OS, etc.
  • When we need to run a test on various web browsers. Scripts written in selenium support most web browsers.
