vscode-test

This module helps you test VS Code extensions. Note that new extensions may want to use the VS Code Test CLI, which leverages this module, for a richer editing and execution experience.

Supported:

• Node >= 16.x
• Windows >= Windows Server 2012+ / Win10+ (anything with Powershell >= 5.0)
• macOS
• Linux

Usage

See ./sample for a runnable sample, with Azure DevOps Pipelines and Github ACtions configuration.
