Below are a list of emulators that Azure offers at the time of writing. Please review documentation and EULA to identify any special requirements or limitations on approved usage. In most cases these are for development purposes only, some you can use with your testing pipelines.
Azure Cosmos DB Allows you to have a local environment that emulates the Azure Cosmos DB service. It also supports migrating data between the emulator and Azure Cosmos DB service using the Azure Cosmos DB Data Migration Tool.

You have the option when you spin the emulator up to do Full or Lite. Lite has the smallest footprint image and is based on Azure SQL Edge’s base image. There are some features in Azure SQL that are not supported. You can use this for automation testing as well in your deployment pipelines.
Azure Storage The new version uses Azurite platform is cross-platform supported, and this supersides the old Azure Storage Emulator. This can also be used in your deployment pipelines.
Azure Function Apps This one would not be a true “emulator” but provides a local environment runtime that allows you to execute and spin up your Function App without having to be connected to the Azure Cloud service. It also supports communicating with the emulators above for a complete development environment.
