How to run .NET unit tests in a docker container

I have a .NET Core application containing MSTest unit tests. What would the command be to execute all tests using this Dockerfile?

FROM microsoft/dotnet:1.1-runtime
ARG source
COPY . .
ENTRYPOINT ["dotnet", "test", "Unittests.csproj"]

Folder structure is:

/Dockerfile
/Unittests.csproj
/tests/*.cs
Solution

  • Use a base image with .NET Core SDK installed. For example:

    microsoft/dotnet
microsoft/dotnet:1.1.2-sdk

    You can't run dotnet test in a Runtime-based image without SDK. This is why an SDK-based image is required. Here is a fully-workable Dockerfile example:

    FROM microsoft/dotnet

WORKDIR /app
COPY . .

RUN dotnet restore

# run tests on docker build
RUN dotnet test

# run tests on docker run
ENTRYPOINT ["dotnet", "test"]

    RUN commands are executed during a docker image build process.

    ENTRYPOINT command is executed when a docker container starts.
