# AWS Lambda Durable Execution Testing for .NET
-> **Preview.** `Amazon.Lambda.DurableExecution.Testing` tracks the `Amazon.Lambda.DurableExecution` runtime package (0.x). Public APIs may change before 1.0.
-
`Amazon.Lambda.DurableExecution.Testing` lets you test [durable workflows](../Amazon.Lambda.DurableExecution/README.md) without deploying to AWS. It drives your workflow handler to a terminal state in-process using the real durable runtime engine backed by an in-memory store, and then exposes the result and every recorded operation for assertions.
You write a test against the `IDurableTestRunner` interface; the same test runs unchanged against the in-memory `DurableTestRunner` (fast, no AWS) or the `CloudDurableTestRunner` (a deployed function).

`Amazon.Lambda.DurableExecution` is the .NET SDK for building resilient, long-running AWS Lambda functions that automatically checkpoint progress and resume after failures. Workflows can run for up to one year, with charges only for active compute time.
