Automation Framework with C#

This framework was built with C# as a baseline for test automation projects, it includes many features that will make the automated scripts easier, these features include:
- Excel sheet utilities in a form of SQL statements
- Reporting features
- Parallel execution
- Selenium grid integration
- Data generator libraries
- Page object model pattern

Automation Script Generator

This project accelerates the scripting process by generating the required UI automation script in Page Object Model pattern, it takes an HTML page as an input and generates the required scripts using a simple interface, it supports generating scripts in the following formats:
- HP QTP script
- LeanFT scripts
- Selenium C#
- Convert from QTP to LeanFT
- Convert from LeanFT to Selenium
- Generate Excel test data files

This application was created using C#.

Java Framework Template

This is a sample data-driven Java framework; it is simple yet powerful by its distinctive data-driven feature by simply using a YAML file to set up the test data for tests, add new tests, or update existing ones.

JMeter Framework

This project describes how to create a reusable JMeter script that takes into consideration the following aspects:
1: Reusability
2: Maintainability
3: Extension

It uses the following components to achieve our target:
1: Simple controller
2: Transaction controller
3: Module controller
4: Test fragment
