Travis.ci环境变量无法在phpunit中读取

Question

有人能帮我理解为什么我的环境变量在travis.ci中的phpunit测试中无法被读取吗？

我正在尝试使用travis为我正在开发的php/javascript应用编写一些自动化测试。然而，当我编写一个测试来检查环境变量是否能够从travis读入到phpunit中时，测试失败了。这意味着（据我所知）要么phpunit无法读取环境变量，要么它们没有正确地传递到travis测试中。

.travis.yml

language: php
php:
  - '7.0'
  - '7.1'

before_install:
  - echo "extension=ldap.so" >>php --ini | grep "Loaded Configuration" | sed -e "s|.:\s||"``

install:
  - cd test
  - npm install
  - cd ..

script:
  - echo $API_BASE_URL
  - phpunit test/build_tests.php

notifications:
    on_success: never
    on_failure: never

phpunit测试文件

<?php

use PHPUnit\Framework\TestCase;

class build_tests extends TestCase
{
    public function testForEnv()
    {
        $this->assertEquals(isset($_ENV['API_BASE_URL']), true);
        $this->assertEquals(isset($_ENV['DRINK_SERVER_URL']), true);
        $this->assertEquals(isset($_ENV['LOCAL_DRINK_SERVER_URL']), true);
        $this->assertEquals(isset($_ENV['RATE_LIMIT_DROPS_DROP']), true);
        $this->assertEquals(isset($_ENV['DEBUG']), true);
        $this->assertEquals(isset($_ENV['DEBUG_USER_UID']), true);
        $this->assertEquals(isset($_ENV['DEBUG_USER_CN']), true);
        $this->assertEquals(isset($_ENV['USE_LOCAL_DRINK_SERVER']), true);
    }
}

?>

Travis 环境变量的导出

$ Setting environment variables from repository settings
$ export DRINK_SERVER_URL=https://drink.csh.rit.edu:8080
$ export LOCAL_DRINK_SERVER_URL=http://localhost:3000
$ export RATE_LIMIT_DROPS_DROP=3
$ export DEBUG=true
$ export DEBUG_USER_UID=[secure]
$ export DEBUG_USER_CN=[secure]
$ export USE_LOCAL_DRINK_SERVER=true
$ export API_BASE_URL='api/index.php?request='

PHPUnit 结果

PHPUnit 6.1.1 by Sebastian Bergmann and contributors. 

F                                                                   1 / 1 (100%)

getenv()能否替代$_EVV呢？https://dev59.com/_G865IYBdhLWcg3whOzE - sman591

Answer 1

尝试使用getenv函数调用。在travis环境中，$_ENV变量不可用。
