What makes this way of test so special ?

Running GitHub Actions --> Same YAML, Everywhere

• Locally
• Continuous Build (Shared build on-premises)
• Remote (Global build Cloud)
• super super fast 🚀🚀🚀

Github Action (Workflows) (YAML) runs inside a Docker Container (Isolated)

• No more "It's works on my machine (mindset) "
• No pollutions
• No Sideeffects on local machine environment
• No maintenance on local machine Dependencies

How to Test inside a docker container super fast 🚀

# how to install 'act' ?  
scoop info act
scoop install act


# run the tests job
act --job test 

# run the the entire pipeline
act 

# view the execution graph (List workflows)
act --list

Run your GitHub Actions locally 🚀

$ act --help 

Run GitHub actions locally by specifying the event name (e.g. `push`) or an action name directly.
