Efficient way to run PowerShell Pester tests from Sublime Text - powershell

Question

I'm using Sublime Text (ST) to create my PowerShell scripts, Pester to test them.
To run test script, one must to switch to that tab, then press CTRL + B. This process must be repeated for each test script.
Is there an easy way to Sublime Text to run all of the tests in the project's directory?
Is there a way to have these test automatically run when a script or test changes (similar to guard)?

Answer 1

I added a script named Tests.ps1 to the project's directory with a single instruction:
Invoke-Pester
To run all tests, I open this file and press Ctrl+B.
** edit **
Created a new build system named 'Pester'. The contents of Pester.sublimebuild:
{
"cmd": ["powershell.exe", "-noprofile", "Invoke-Pester"],
"selector": "source.powershell"
}
To run all tests, press Ctrl+B.
If this doesn't work automatically, assign Pester as the build system using Tools | Build System | Pester and try again.
