Вопрос:
Я пытаюсь добавить тестовые примеры для приложения django, но тест успешно проходит локально, но не выполняется на Travis CI.
M .travis.yml файлов выглядит следующим образом:
dist: bionic
services:
- postgresql
addons:
postgresql: '9.5'
apt:
packages:
- postgresql-9.5
before_script:
- psql -c 'create database fecundity_test;' -U postgres
branches:
only:
- "master"
language: python
python:
- "3.8"
install:
- if [ "$TRAVIS_BRANCH" = "master" ]; then pip install -r requirements/dev.txt; fi
- if [ "$TRAVIS_BRANCH" = "master" ]; then pip install coveralls; fi
script:
- if [ "$TRAVIS_BRANCH" = "master" ]; then ./scripts/lib/run-ci; fi
after_success:
- if [ "$TRAVIS_BRANCH" = "master" ]; then coveralls; fi
И мой settings.py выглядит так:
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.postgresql_psycopg2',
'NAME': os.environ['POSTGRES_DB'],
'USER': os.environ['POSTGRES_USER'],
'PASSWORD': os.environ['POSTGRES_PASSWORD'],
'HOST': os.environ['POSTGRES_HOST'],
'PORT': '',
'ATOMIC_REQUESTS': True,
'TEST': {
'NAME': os.environ['POSTGRES_TEST_DB']
}
},
}
Когда я запускаю его на travis, я получаю этот журнал ошибок:
$ if [ "$TRAVIS_BRANCH" = "master" ]; then ./scripts/lib/run-ci; fi
Using existing test database for alias 'default' ('fecundity_test')...

to avoid running initialization queries against the production database when it's not needed
(for example, when running tests). Django was unable to create a connection to the 'postgres'

Я понятия не имею, что работает, и я попытался выполнить поиск в Интернете, но не смог найти никакой помощи. И дальнейший CI проходит без тестов. Заранее спасибо.
Ответ №1:
После стольких усилий я понял, что причиной сбоя было то, что я не добавил переменные EVN в Travis CI. Если вы получаете ту же ошибку, убедитесь, что вы добавили переменные в настройки среды TravisCI.
