Automated Testing

Automation testing is a software testing approach that uses special automated test tools to perform a test case suite. On the other side, manual testing is conducted by a person’s direct engagement where a person sits in front of a computer and runs test procedures.

Automation testing tools can also put test data into the System Under Test and produce comprehensive test reports and actual results. It necessitates a significant investment of money and resources, and the execution of the identical test suits repeatedly is required for a successful development cycle to occur.

You can use a testing automation tool to record and replay this test suit as needed. When automated tests are in place, there is no need for human input, validating the ROI of test automation.

Automation testing focuses on reducing the number of test cases while also attempting to eliminate manual testing.

Parameters To Consider While Choosing A Programming Language For UI Test Automation

The following are the parameters to put into consideration while evaluating any programming language for automation:

  • Elegance: It is the process of turning test cases into code to make them simple and understandable. Ensure that the test cases are as brief and self-explanatory as possible for long-term maintainability.
  • IDE Support: Ensure it supports IDE because vim and Notepad are insufficient for large projects.
  • Usability: A good automation language should be high-level and handle routine activities such as memory management. It is suggested that it acquires a low learning curve.
  • Available Packages: It’s usually preferable to utilize pre-prepared packages for simple operations like SSH, HTTP requests, and web drivers.
  • Industry Adoption: If the automation language continues to be in demand, development tools and packages will be kept up.
  • Available Test frameworks: It provides a minimal set of features, such as reporting, fixtures, cleaning, and logging.
  • Powerful Command Line: For continuous integration, it’s essential to have a powerful CLI.
  • Easy Build Integration: Make sure the automation’s tests are completed, and the results are generated.

Why Should You Write UI Test Automation?

Automation testing is a complex and time-consuming process that requires significant expertise and effort. Knowledge of how to choose frameworks, programming languages, and programming paradigms, test data creation and debugging, as well as the problems associated with testing in general, like boundary value analysis and equivalence partitioning.

It also necessitates an actual amount of effort. The creation of new tests requires as much programming expertise as developers might have, and keeping them up to date requires an understanding of the firm’s most current needs.

Thus, UI test automation is essential, and it provides two things in addition: speed and confidence.

In contrast to what common sense would tell, speed and confidence typically go hand in hand when testing. When there is a solid UI automation test suite, engineers find fewer bugs in production, which means more time spent on development and less time on bug fixes. As a result, developers spend more time developing new features.

What Is Selenium Automation Testing?

Selenium is a collection of open-source software testing automation solutions that has rapidly become the industry standard for quality assurance.

Selenium is now in use in the production environment by companies such as Netflix, Google, HubSpot, Fitbit, and more, with a list of several programming languages and all major operating systems.

The whole suite has many testing solutions to meet a variety of testing needs. The most significant feature of this tool’s new approach is that testers can communicate in their preferred programming language with the browser.

Selenium WebDriver

When most people talk about Selenium, they refer to Selenium WebDriver, which receives the most attention during the development process.

The way WebDriver’s test automation works is frequently compared to taxi driving. The three components in taxi driving and test automation are customer/test engineer, car/browser, and taxi driver/WebDriver.

According to this analogy, a tester instructs WebDriver to work with the components the same way a client instructs a taxi driver. Then, with WebDriver, the web browser (the car) receives vocal commands that look like this: click the button when it’s enabled. The browser then gives WebDriver information on the values and states of web elements, subsequently sent to the script.

Going Beyond With UI Automation

Even if you explain the significance of having an attribute, the developers may not write them for you for various reasons. It’s not because they don’t like you.

Developers, just like testers, are pretty busy; they have deadlines to meet, bug fixes to deploy, project management responsibilities on their shoulders, and your requirements aren’t the highest priority in many cases. It is also an opportunity to distinguish yourself.

Creating your attributes in the front end will necessitate learning new skills and obtaining permission from the front-end team. However, if you’re able to accomplish that, you’ll be far above the average automation engineer in terms of competence, and it will certainly show in your subsequent personal evaluation.
