💡 Hint

Common Mistakes

Using 'python' instead of 'pytest' to run tests.

Trying to install pytest instead of running it.

The pytest command runs the tests inside the Docker container. Using python or bash won't run tests directly, and pip install pytest is for installing, not running tests.

Complete the code to mount the current directory into the Docker container for test access.

PyTest

docker run --rm -v [1]:/app -w /app python:3.12 pytest

💡 Hint

Common Mistakes

Using a fixed path instead of the current directory.

Not mounting the directory, so tests can't find the code.

Using $(pwd) mounts the current directory from the host into the container, allowing tests to access the code.

Fix the error in the Docker command to ensure the working directory is set correctly for pytest.

PyTest

docker run --rm -v $(pwd):/app -w [1] python:3.12 pytest

💡 Hint

Common Mistakes

Setting working directory to a path not matching the mounted volume.

Using default working directory which may not contain the tests.

The working directory inside the container must match the mount point /app so pytest finds the tests.

4fill in blank

hard

Fill both blanks to create a Docker command that installs pytest and runs tests inside the container.

PyTest

docker run --rm -v $(pwd):/app -w /app python:3.12 bash -c "[1] && [2]"

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Running tests without installing pytest first.

Using wrong test command like 'python test.py' instead of 'pytest'.

First, pip install pytest installs pytest, then pytest runs the tests.

5fill in blank

hard

Fill all three blanks to define a Docker Compose service that runs pytest with mounted volume and working directory.

PyTest

services:
  test:
    image: python:3.12
    volumes:
      - [1]:/app
    working_dir: [2]
    command: [3]

💡 Hint

Common Mistakes

Using wrong mount path or working directory.

Forgetting to set the command to 'pytest'.

The volume mounts the current directory . to /app. The working directory is set to /app, and the command runs pytest.
