Write tests with Pester. Tests go in the `Tests` directory. Tests should always
clean-up after themselves and strive to leave an operating system in the exact state
it was in before the test fixture ran.
Unfortunately, we only have the resources to run our tests on a 64-bit Windows 2012 R2
and 7 computer. Any donations to the project would be used to purchase licenses and
hosting for running our tests on 32-bit and 64-bit versions of Windows 7, Windows
2008 R2, and Windows 2012 R2.
Carbon uses semantic versioning (see http://semver.org/). Carbon version numbers
take the form X.Y.Z: X is the major version, Y is the minor version, and Z is the
patch version. The patch version is incremented when backwards-compatible bug
fixes are made. You should feel comfortable rolling out a new patch version
quickly, with limited testing. The minor version is incremented when new,
backwards-compatible changes are introduced, or existing functions are deprecated.
You'll probably want to review the release notes and test those bits that changed since the last release. The major version is incremented when backwards-incompatible changes are made. In this case, you'll need to do thorough
testing, and upgrade your scripts to use new functionality.
We use spaces for indenting. Each level of indent (i.e. "tab") should be four spaces.
This is default in the PowerShell ISE.
Use camel-casing for all function names, including abbreviations three letters or
longer, e.g. Install-CMsmq, Install-CIisWebsite. Capitalize all letters in one or two
letter abbreviations, e.g. Test-COSIs32Bit.
All function parameter and module variables names must be capitalized, e.g. `$Path`,
`$Name`, etc. All variable names should be lowercase, e.g. `$result`, `$csprojXml`.
Variables that contain a path should end in `Path`, e.g. $csprojPath, $websitePath.
*Always* use an [approved PowerShell verb](http://msdn.microsoft.com/en-us/library/windows/desktop/ms714428.aspx).
If possible, use an [approved PowerShell parameter name](http://msdn.microsoft.com/en-us/library/windows/desktop/dd878352(v=vs.85).aspx).
Use a prefix for all functions that manage a common area of Windows, e.g. Iis for all
IIS-related functions, Msmq for MSMQ-related functions, etc.
All functions must have synopsis, description, and example documentation.
