Build

Testing

There are not any Docker-in-Docker supported Windows images for now, rancher/wins has to separate the validation test and integration test.

For validation test, which could be embedded into a containerized CI flow, please run the below command in PowerShell:

> make.bat

For integration test, please run the below command in PowerShell:

> make.bat integration

Note: Don't use bin/wins.exe after integration testing. Please make.bat build again.

If want both of them, please run the below command in PowerShell:

> make.bat all
