PHPUnit test suite include path

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:

Answer 1

First, I don't get how require_once('../StringCalculator.php'); works, it should rather be: require_once('../Application/StringCalculator.php');.

Then, slashingweapon answer is good and it's the best IMO, however if you don't want that much trouble, you can specify your require_once to start from the directory of the current file:

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

Answer 2

I know the question already been answer
This answer is for future visitor

According to phpunit documentation, u can use includePath directive in your phpunit.xml for your inclusion path

<php>
  <includePath>/path/to/ur/project</includePath>
</php>

Answer 3

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.
