Test your Liquid transformations without deployment

I work on a project doing integration with Azure Integration Services and Azure Functions. As always in integration projects doing mapping is a key area. I’m used from BizTalk development to be able to test my maps without doing deployment which makes it easy to develop in an iterative manner. While working with Logic Apps I started using Liquid transformations and did not find any tool to help with that. Logic Apps transforms with the DotLiquid library (C# Naming conventions). With that information in hand I created a program to test. I separated it in two a library, LiquidTransformationLib.dll, and a program, LiquidTransform.exe. The library makes it easy to use in automated tests.

Parameters for LiquidTransform.exe:

Parameter Description Required
-t | –template Full path to the Liquid template to use. Yes
-c | –content Full path to Content file. Yes
-d | –destination Full path to destination file. Will overwrite an existing file Yes
-r | –rootelement Root element to add before render. For Logic Apps you will need to use content No
-u | –rubynaming Use RubyNamingConvention, Logic Apps use C# naming conventions and will be the default. No
-? | -h | –help Show help information No

  1. This was a magic solution. I began my Liquid-journey for literally 1½ hour ago and came across this post.
    THANKS!
    This will save me tons of time compared to testing using Logic Apps.
