我如何调试失败的ci构建？

Question

i created some tests with PHPUnit and laravel. The tests are running locally successful, but as a gitlab ci job there is an error.

Here is the ci log:

There was 1 failure:

1) Tests\Feature\AuthTest::testAuthLoggedInIsAdmin
Expected status code 200 but received 500.
Failed asserting that false is true.

/builds/XXX/webproject/vendor/laravel/framework/src/Illuminate/Foundation/Testing/TestResponse.php:55
/builds/XX/webproject/tests/Feature/AuthTest.php:53

For the better debug and finding a solution i need the error trace from the project or the error.log from the webserver.

What is the best practise to debug errors in the ci?

Answer 1

ok, the solution is very simple... i don't delete the question. Here is the solution:

You have to add an artifact to the job. You can set the artifact, that only on failures the artifact is created. If there is an failure on the build, the hole project is dumped to a seperated location. Now you can browse each files on the dump.

.gitlab-ci.yml

stages:
  - test
  - deploy

php-7.0:
  stage: test
  type: test
  services:
    - mysql:latest
  image: tetraweb/php:7.0
  script:
    - bash .gitlab-ci.sh
    - php vendor/bin/phpunit --coverage-text --colors=never
  artifacts:
    when: on_failure
    name: "${CI_BUILD_STAGE}_${CI_BUILD_REF_NAME}_FAILED"
    paths:
      - "."
    untracked: false
    expire_in: 1 day

deploy:
  stage: deploy
# etc...

Here are more informations about artifacts.

You can download the artifacts in the pipelines section in gitlab:
