Travis.ci Environment Variables not reading in phpunit - php

Question

Can someone help me understand why my environment variables aren't being read inside of my phpunit test from travis.ci?
So I'm attempting to write some automatic testing using travis for a php/javascript app I'm working on. However when I wrote a test to check for environment variables reading into phpunit from travis, they fail. That means (as far as I can tell) that either the environment variables aren't able to be read by phpunit, or they aren't being passed through to the travis test properly.
.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 Test File
<?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);
}
}
?>

Can someone help me understand why my environment variables aren't being read inside of my phpunit test? I would really appreciate it.

Try using getenv function call instead. In travis enviroment the $_ENV variables are not available
