如何在多个不同的 php 环境中运行 PHPunit 测试套件？

Question

I should run a PHPUnit 3.7 test suite in different php environments: with different php.ini settings and even in different OS environment. I want to make sure that my test suite and the underlying classes work constantly when

• php.ini date.timezone setting varies; and/or
• OS's internal timezone varies

How to properly do set-up the test environment in PHPUnit and in CLI (Linux)?

Answer 1

If you all you want to is to change php.ini settings and maybe OS/env vars I'd suggest writing little bash script wrappers (or using your build tool of choice) to do the equivalent.

Using PHP 5.3 with a different timezone:

/path/to/php-5.3 -d date.timezone=America/New_york /usr/bin/phpunit

Using PHP 5.4 with another timezone and differnt ENV

export TZ=Europa/Berlin 
/path/to/php-5.4 -d date.timezone=Aemerica/San_Franciso /usr/bin/phpunit

This approach will also work with process_isolation if you use that feature as PHPUnit will be able to figure out what PHP binary was used but you might have issues with the "-d" parameters. In that case don't pass them to the php binary but to phpunit. ( phpunit -d date.timezone=foo ). PHPUnit will then take care of setting it before your tests run.
