What is Microsofts Unit Testing for Logic Apps

At the Integrate 2025 summit, Microsoft went live with the GA of Logic App Unit Testing.

This is an out of the box offering from Microsoft rather than a 3rd party or open source offering.

The aim of the framework is to sit between the test code such as MsTest and the Logic App runtime for Logic App Standard and it will help you to build unit tests that can be executed within the normal process of unit testing for .net and Azure developers.

Constraints

• It is intended to mock all of the connectors within the Logic App Standard, you will execute a workflow run but all of the connector calls with used mocked responses provided by your test.  The testable unit here is the workflow logic and not the end to end integration process.
