Problem

While writing Integration Tests for our services that rely on Azure Key Vault to retrieve secrets and certificates, we have to basically mock the process as Azure Key Vault does not at this time provide an emulator that allows us to simply integrate this support with test containers.

Thankfully, Esta Nagy has created Lowkey Vault which aspires to be compatible with Azure Key Vault REST APIs.

Solution

Implementation of Lowkey Vault Test Container for .NET. We can take inspiration from the Test Container version for Java found here

More Details on LowKey Vault can be found from the links below

LowKey Vault Assumed Identity, this allows us to use DefaultAzureCredential
Assumed Identity endpoint in Lowkey Vault

Benefit

1. This would make writing integration tests for services that integrate Azure KeyVault a breeze using Test Containers without making any major changes to our existing codebases.

Alternatives

• Manually Spinning up a Docker Instance of Lowkey Vault separately.
• Mock The KeyVault Secret and Certificate Retrieval Process
