What is Automation?

Why do we automate?

When there are Frequent releases/code changes

To Reduce Execution Cycle time Saves time and money

Large number of Boundary Value test cases

Enable continuous delivery

Catches problem quickly

Improves accuracy Increase Test Coverage

Tools & Technologies

Most Extensively Used Test Automation Tools

Test automation cannot be realized without good tools; as they determine how automation is performed and whether the benefits of automation can be delivered. Test automation tools is a crucial component in the DevOps toolchain. The current test automation trends have increased in applying artificial intelligence and machine learning (AI/ML) to offer advanced capabilities for test optimization, intelligent test generation, execution, and reporting. It will be worthwhile to understand which tools are best poised to take advantage of these trends.

Available Tools for Automation

The top of almost every rank is Selenium. It is an open-source cross-platform framework for testing web applications. Auto scripts can be written in Java, C#, Python, PHP, Ruby, Perl and JavaScript. The framework includes Selenium Grid, Selenium Remote Control and Selenium IDE. Having rather high capacities, Selenium can be used for performance testing of web-based products.
