Mittons.Fixtures is a framework for standing up testing environments via fixtures, which can be integrated into other testing frameworks.


This project was created to allow developers to declare their environments in a fixture using attributes to define service settings, allowing the testing framework to spin up the full environment. This saves developers the need to create pre/post test scripts that build/teardown the testing environment, and keeps the environment definition closer to the actual tests.


Currently, this library uses Docker for spinning up the test environment. To define an environment, you would create a class extending the DockerEnvironmentFixture, and define all the containers you wish to stand up. When you define a fixture, the following attributes can be applied:

  • [Run(string)] - Defines the details for the run, this currently only accepts a string representing an environment variable from which to get an id to apply to all resources created in the test environment. This allows you to use that identifier for post-test cleanup action in the instance the tests are cancelled prematurely and normal cleanup behavior does not occur.
  • [Network(string)] - Defines a Docker network to create.

Supported container types are:

  • Container: This is the base class for all containers, so if an abstraction for your container type doesn't exist, this is where you would start. All containers support the following attributes:
    • [Image(string)] - Defines the image used to create the container.
    • [Command(string)] - Defines the command Docker runs once the container is started.
    • [HealthCheck(Disabled = boolean, Command = string, Interval = TimeSpan, Timeout = TimeSpan, StartPeriod = TimeSpan, Retries = int)] - Defines the settings for Docker to perform health checks on the container.
    • [NetworkAlias(string, string)] - Defines a Docker network to which the container should be attached, and the alias by which other containers on the network can communicate with it.
  • SftpContainer: Extending Container, this adds extra convenience functionality specific to spinning up and Sftp server. SftpContainers are built using the atmoz/sftp:alpine image, and since that assumes certain behaviors, [Image] attributes will be ignored for these containers. In addtion to the normal Container attributes, SftpContainer supports the following attributes:
    • [SftpUserAccout(string, string)] - Adds an account to the sftp server using the provided username and password.

A good reference on how do define an environment can be found in the Mittons.Fixtures.Example project, which is designed to demo this library.


Note: This example leverages the SSH.NET library
