13 Best Test Automation Frameworks: The 2021 List

Automation frameworks enable automation testers by simplifying the test development and execution activities. A typical automation framework provides an environment for executing test plans and generating repeatable output. They are specialized tools that assist you in your everyday test automation tasks. Whether it is a test runner, an action recording tool, or a web testing tool, it is there to remove all the hard work from building test scripts and leave you with more time to do quality checks. Test Automation is a proven, cost-effective approach to improving software development. Therefore, choosing the best test automation framework can prove crucial to your test results and QA timeframes.

Desired Capabilities in Selenium Webdriver

Desired Capabilities is a class used to declare a set of basic requirements such as combinations of browsers, operating systems, browser versions, etc. to perform automated cross browser testing of a web application.

Continuous Integration explained with jenkins deployment

Continuous integration is a coding philosophy and set of practices that encourage development teams to make small code changes and check them into a version control repository regularly. Most modern applications necessitate the development of code across multiple platforms and tools, so teams require a consistent mechanism for integrating and validating changes. Continuous integration creates an automated way for developers to build, package, and test their applications. A consistent integration process encourages developers to commit code changes more frequently, resulting in improved collaboration and code quality.

How To Test React Native Apps On iOS And Android

As everyone knows, the mobile industry has taken over the world and is the fastest emerging industry in terms of technology and business. It is possible to do all the tasks using a mobile phone, for which earlier we had to use a computer. According to Statista, in 2021, smartphone vendors sold around 1.43 billion smartphones worldwide. The smartphone penetration rate has been continuously rising, reaching 78.05 percent in 2020. By 2025, it is expected that almost 87 percent of all mobile users in the United States will own a smartphone.

How To Use Appium Inspector For Mobile Apps

Let’s put it short: Appium Desktop = Appium Server + Inspector. When Appium Server runs automation test scripts, Appium Inspector can identify the UI elements of every application under test. The core structure of an Appium Inspector is to ensure that you discover every visible app element when you develop your test scripts. Before you kickstart your journey with Appium Inspector, you need to understand the details of it.
