travis-ci - {before_,}{install,script} .travis.yml 选项之间有什么区别？

Question

在.travis.yml配置文件中，before_install、install、before_script之间的实际区别是什么和脚本选项？

我没有找到任何文档来解释这些选项之间的差异。

您不需要使用这些部分，但如果您这样做，您就传达了您正在做的事情的意图:

before_install:
  # execute all of the commands which need to be executed 
  # before installing dependencies
  - composer self-update
  - composer validate

install:
  # install all of the dependencies you need here
  - composer install --prefer-dist

before_script:
  # execute all of the commands which need to be executed 
  # before running actual tests
  - mysql -u root -e 'CREATE DATABASE test'
  - bin/doctrine-migrations migrations:migrate

script:
  # execute all of the commands which 
  # should make the build pass or fail
  - vendor/bin/phpunit
  - vendor/bin/php-cs-fixer fix --verbose --diff --dry-run
