tasks.json

// A task runner that invokes Pester to run all Pester tests under the
// current workspace folder.

// NOTE: This Test task runner requires an updated version of Pester (>=3.4.0)
// in order for the problemMatcher to find failed test information (message, line, file).
// If you don't have that version, you can update Pester from the PowerShell Gallery
// with this command:
//
// PS C:\> Update-Module Pester
//
// If that gives an error like:
// "Module 'Pester' was not installed by using Install-Module, so it cannot be updated."
// then execute:
//
// PS C:\> Install-Module Pester -Scope CurrentUser -Force
//

// NOTE: The Clean, Build and Publish tasks require PSake. PSake can be installed
// from the PowerShell Gallery with this command:
//
// PS C:\> Install-Module PSake -Scope CurrentUser -Force
//

// Available variables which can be used inside of strings.
// ${workspaceRoot}: the root folder of the team
// ${file}: the current opened file
// ${fileBasename}: the current opened file's basename
// ${fileDirname}: the current opened file's dirname
// ${fileExtname}: the current opened file's extension
// ${cwd}: the current working directory of the spawned process
