How to: Run tests with Docker

If you want to skip the installation of AltWalker you could use one of our docker images.

Create a Dockerfile for your project

To use altwalker with docker add the following Dockerfile in the root of your project.

Python

Dockerfile

FROM altwalker/altwalker:latest

COPY . /test-project
WORKDIR  /test-project

RUN touch requirements.txt
RUN python3 -m pip install -r requirements.txt

# If you have other dependencies you can install them here.

C#/.NET

Dockerfile

FROM altwalker/altwalker:latest-dotnet-2.1

COPY . /my-tests
WORKDIR  /my-tests

# If you have other dependencies you can install them here.

RUN dotnet build tests

You can then build and run the Docker image:

docker build -t my-tests .
docker run -it my-tests altwalker online [...]

Example:

docker build -t my-tests .
docker run -it my-tests altwalker \
    online tests -m models/default.json "random(vertex_coverage(100))"

Run your tests as a script

For many projects you may find it inconvenient to write a complete Dockerfile. In such cases, you can run you tests as a script by using the AltWalker Docker image directly:

Python

docker run -it -v "$(pwd):/test-project" -w "/test-project" altwalker/altwalker:latest \
    /bin/bash -c 'python3 -m pip install -r requirements.txt && altwalker online [...]'

If you don’t have any python dependencies you can remove the python3 -m pip install -r requirements.txt.

docker run -it -v "$(pwd):/test-project" -w "/test-project" altwalker/altwalker:latest \
    altwalker online [...]

C#/.NET

docker run -it -v "$(pwd):/test-project" -w "/test-project" altwalker/altwalker:latest-dotnet-2.1 \
    altwalker online [...]

Example:

Python

docker run -it -v "$(pwd):/test-project" -w "/test-project" altwalker/altwalker:latest \
    /bin/bash -c 'python3 -m pip install -r requirements.txt && altwalker online tests -m models/default.json "random(vertex_coverage(100))"'

C#/.NET

docker run -it -v "$(pwd):/test-project" -w "/test-project" altwalker/altwalker:latest-dotnet-2.1 \
    altwalker online tests -m models/default.json "random(vertex_coverage(100))"
