  • GUI Automation
  • Full Stack Automation
  • Test Automation

GUI Automation Python library

  • It supports the concept of dependency-based programming but also comes along with a strong plugin mechanism that allows the construction of build life-cycles similar to those known from other famous build tools like Apache Maven and Gradle.

Test Automation

1) Robot Framework

  • This is a generic open-source automation framework.
  • It is used for test automation and robotic process automation (RPA).
  • It also includes a bunch of test libraries and other tools.
  • The Robot Framework is Python-based, but you can also use Jython (Java) or IronPython (.NET).
  • Robot can also test other things like:
    • FTP
    • MongoDB
    • Android
    • Appium
    • APIs
    • Mainframes

2) Pytest

  • Pytest is a  framework that allows us to write test codes using python.
  • You can write code to test anything like database, API, even UI if you want. But pytest is mainly being used in the industry to write tests for APIs.

3) Lettuce

  • Lettuce is another simple and easy to use behavior driven automation tool based on Cucumber and Python.
  • The main objective of Lettuce is to focus on the common tasks of behavior driven development, making the work simpler and entertaining.
