With App Engine, the Go Runtime is a mashup of Python Runtime, Go SDK and glue code (Go and Python). This poses some challenges during development, which this proposal addresses with solutions.

Development Tool for go app engine development, that presents an easier to use wrapper for App Engine development with GO Runtime, bypassing some pitfalls caused by integration with the Python SDK.

The source is available online, and the motivation for building this is described below. What irks one person may not irk the other, so your utility of this tool may differ from mine. For me, the utility is really high:

With changes to allow concurrent requests in Go App Engine, Testing support follows naturally and natively.

Following support for concurrent requests described previously, Testing support is as easy as ensuring the following is called one time before your test is run. I have tested it and it works flawlessly.

This details how to enable concurrent requests in the Go App Engine SDK.

This attempts to make a case for datastore enhancements in the GO Language Runtime of App Engine.
