Reorganize unit tests All code for unit tests is now under the `PhpSpreadsheet\Tests` namespace which is autoloaded via composer mechanism. So there is no need for `require()` anymore. Also, tests were moved in `tests/` folder and phpunit should be executed from the project root folder. This is to conform to the de facto standard, notably in use in phpunit itself. 2016-08-13 17:22:11 +00:00			`-1.5, -1`
