Question

Using phpunit and I am having some trouble with include paths, not for phpunit itself, but for my code and tests directory.

I have the following code structure:

Application
  -StringCalculator.php

tests
  -StringCalculatorTest.php

Inside my StringCalculatorTest.php i have a require statement:

require_once('../StringCalculator.php');

Running phpunit StringCalculatorTest.php from inside the tests folder works perfectly.

However, when i then introduce a phpunit.xml configuration file in the root directory i.e.

Application
  -StringCalculator.php

tests
  -StringCalculatorTest.php

phpunit.xml

the include path is screwed. I have to replace the require_once to

require_once('StringCalculator.php');

What is the correct way to set include paths between the application and the test directory?

Answer 1

The best place to set your PHP include path is in your bootstrap file. Usually, your phpunit.xml file will include a bootstrap attribute:

<phpunit backupGlobals="true"
     backupStaticAttributes="false"
     bootstrap="bootstrap.php"
     cacheTokens="true"
     colors="true"
     ... and so on ...
</phpunit>

Then in your bootstrap file you can set include paths, include important files, etc..

set_include_path(get_include_path() . PATH_SEPARATOR . '../my/sources');

The config file is covered in Appendix C of the PHPunit docs.
