Is Java important for learning automation tests

The top 5 tools for automation testing

Automation testing is a software technique that can be used to compare the actual outcome of software with the expected outcome.

You may need to use test automation software to automate repetitive tasks and other test tasks that are difficult to perform manually. You can do this either by writing automation test scripts or by using an automation test tool.

Test automation software has started applying Artificial Intelligence and Machine Learning (AI / ML) to provide advanced optimization, intelligent test generation, execution, and reporting capabilities.

Here are a few tools that will help you take advantage of these trends.

1. Selenium

Selenium is the industry standard for test automation. It is a free, automated, open source testing framework that can be used to validate web applications across different browsers and platforms.

Selenium is not just a single tool, but a suite of software, each offering a different approach to aligning with a company's testing needs. It has three main components:

  • WebDriver: Uses browser automation APIs to control the browser and run tests. It is like a real user is operating the browser
  • IDE (Integrated Development Environment): The tool you will use to develop your Selenium test cases. It's an easy-to-use Chrome and Firefox extension, and generally the most efficient way to develop test cases
  • Grid: Allows test cases to be run on different computers on different platforms

To use Selenium effectively, users need to have advanced programming skills and spend significant amounts of time building the automation frameworks and libraries required for automation.

2. Appium

Appium is a free, open source test automation framework that is primarily intended for mobile applications. The type of applications for which it is provided include:

  • Native apps: Written with the SDKs for iOS, Android or Windows
  • Mobile web apps: Access via a mobile browser (Appium supports Safari on iOS and Chrome or other integrated browsers on Android)
  • Hybrid apps: Use a wrapper around a web view - a native control that allows you to interact with web content

Appium is designed to meet the philosophy of mobile automation as described in the following principles:

1. You shouldn't have to recompile or modify your app in any way to automate it:

Appium accomplishes this by using manufacturer-provided automation frameworks under the hood, including:

  • iOS 9.3 and higher: Apple's XCUITest
  • iOS 9.2 and earlier: Apple's UIAutomation
  • Android 4.3+: Google's UiAutomator / UiAutomator2
  • Windows: Microsoft WinAppDriver

2. You shouldn't be tied to a specific language or framework to write and run your tests:

Appium addresses this problem by integrating the frameworks provided by the manufacturer into the WebDriver API. It is a client-server architecture and the client, written in any language, can be used to send the appropriate HTTP requests to the server.

3. A mobile automation framework shouldn't reinvent the wheel of automation APIs:

Appium has not created a new automation standard for testing mobile applications. Instead, the existing W3C WebDriver is expanded to include additional API methods for mobile automation.

3. Katalon Studio

Katalon Studio is a powerful and comprehensive automation solution for testing API, web, mobile and desktop applications. It also has extensive functionality for these tests and supports multiple platforms including Windows, macOS, and Linux.

Katalon Studio offers a wide variety of functions:

  • Intelligent waiting: Fix problems with the wait function in Selenium WebDriver
  • Desktop tests: Supports testing desktop apps on Windows 10
  • Sharing test artifacts: Share test cases, test items and keywords between team members
  • Comprehensive data-driven tests: Custom data sources and advanced capabilities for developing test cases with data-driven methods
  • WebDriver event listener: Use this advanced listener to handle WebDriver-raised events

For a detailed understanding of all these functions, see the official documentation from Katalon Studio.

Katalon Studio offers a free edition and two paid editions that you can choose depending on the project size and requirements.

4. TestComplete

TestComplete is an automated test environment for a wide variety of application types and technologies including (but not limited to) Windows, .NET, WPF, Visual C ++, Visual Basic, Delphi, C ++ Builder, Java, and web applications and services.

TestComplete consists of four main components:

  • TestComplete platform: TestCompleteDesktop, mobile automated testing tools, and the web help you create robust automated tests across devices, platforms, and environments smoothly and instantly
  • TestCompleteDesktop module: With TestComplete Desktop, which is supported by TestComplete Platform, lets you run unit test languages ​​such as TestNG, PyUnit, Ruby, PHPUnit, Junit, and NUnit
  • TestCompleteWeb module: The TestCompleteWeb module enables you to create functional tests for websites and automated graphical user interfaces (GUI), web applications, and mobile applications
  • TestCompleteMobile module: With this module you can create robust automated tests for mobile, native, web or hybrid mobile Android applications

TestComplete comes with out-of-the-box integrations for CI / CD tools like Jenkins and Jira, popular open source frameworks, and tools like Selenium and SoapUI.

You can run tests in parallel in more than 1,500 remote test environments, including browsers, operating systems, and devices.

TestComplete offers a free 30-day trial in addition to its paid plans.

5. LambdaTest

With LambdaTest you can run end-to-end automation tests for a safe, reliable and scalable Selenium infrastructure.

The main features of the LambdaTest include:

  • Automated cross-browser tests with Selenium scripts in over 2000 browsers and operating system environments
  • Integration with various CI / CD tools such as Circle CI, Jenkins and Travis CI
  • LambdaTest uses IP2Location to determine your geolocation, which will direct you to the closest data center. This way you will get the best possible performance every time
  • Automated screenshot testing allows you to capture up to 25 screenshots of various browser and operating system configurations in a single session. This is facilitated by instrumented UI test cases so you can see how seamlessly your web app will render with different browsers over different screen sizes

LambdaTest offers a lifetime free plan with limited features. It also offers some paid plans for more enterprise-level testing capabilities.

Choose the right tool

Choosing the right tool depends not only on the size and type of your project, but also on the potential trends and improvements the tool has to offer.

Automation testing is a hot area that is constantly evolving and taking into account emerging trends like AI and machine learning. The increasing need for codeless testing will create more opportunities for existing tools and create new players in the automation testing space.
