Gitlab CI/CD Pipeline Runs Django Unit Tests Before Migrations

Question

Problem

I'm trying to set up a test stage in Gitlab's CI/CD. Locally, running the unit tests goes fine and as expected. In Gitlab's CI/CD, though, when running the script coverage run manage.py test -v 2 && coverage report the unit tests are executing before the migrations are completed in the test database, which is unexpected, and will always fail. Migrations on the test database need to run prior to unit tests executing.

Any idea why this behavior might happen?

When running python manage.py test these are the steps that happen by default:

Creation of test databases.
Database migration.
Run system checks.
Running tests.
Report on the number of tests and success / failure.
Removing test databases.

In the local test run output below, you can see those exact steps, in that sequence happening. The problem is that in Gitlab's CI/CD pipeline, step 2 and 4 are switched for some mysterious reason to me.

Things I've already tried

Removing coverage, and only executing python manage.py test Result: same error
Removing user test, where Gitlab says the test fails: Result: same error
Removing all but one unit test to attempt to isolate: Result: same error
Adding and activating a virtual environment inside Gitlab's container: Result: same error
Trying a SQLite3: Result: migrations fail due to necessary array field necessary in the project not supported in SQLite3

Gitlab CI/CD Output

My actual output is much bigger. But here's the relevant parts:

.gitlab-ci.yml file

My actual file is much bigger. But here's the relevant parts:

services:
    - docker:20.10.7-dind
    - postgres:latest

stages:
    - test


variables:
    POSTGRES_DB: test_mia
    POSTGRES_USER: mia_dev
    POSTGRES_PASSWORD: test123

build_test_db:
    image: postgres
    script:
        - export PGPASSWORD=$POSTGRES_PASSWORD
        - psql -h "postgres" -U "$POSTGRES_USER" -d "$POSTGRES_DB" -c "SELECT 'OK' AS status;"

test:
    image: python:3.8-slim-buster
    stage: test
    before_script:
        - |
            apt-get update && apt-get install -y --no-install-recommends \
            gcc \

            python3-dev \
            libpq-dev \
            libgnutls28-dev \
            git \
            && rm -rf /var/lib/apt/lists/*
        - python -m pip install --upgrade pip
        - pip install uwsgi
        - pip install -r requirements.txt
        - echo $TEST_SECRETS | base64 -d > config/settings/local.py
    script:
        - echo RUNNING UNIT TESTS
        - coverage run manage.py test -v 2 && coverage report
    needs:
        - ["build_test_db"]
    environment: test
    # only:
    #     - develop

Add a python manage.py migrate line before coverage run manage.py test ... in the scripts section of your gitlab-ci.yml.
