Add note about calling parent::setUp()

[jdietrch]

After adding a setUp() method to my database testing class, the database initialization process wasn't happening properly anymore.This seems to be the same problem that was asked and answered here:
http://stackoverflow.com/questions/9490397/dbunit-in-phpunit-is-not-truncating-the-tables

So I added parent::setUp(); as the first line of my setUp() method, and it's working again.
It would be helpful if the phpunit documentation would make it clear that it is important to call parent::setUp() when overriding the setUp() method, in at least some conditions.

It should probably be mentioned in chapter 4 "Fixtures" where it talks about the setUp() method. Perhaps something like: "If you do override setUp(), don't forget to begin with a call to parent::setUp() if this or that condition applies. Otherwise, this or that thing won't happen anymore, with these undesireable results."

And it should probably also be mentioned somewhere in chapter 8 "Database Testing". Perhaps something like: "If you override setUp() as described in chapter 4, be sure to call parent::setUp(), for this and that reason. Otherwise, this or that other thing won't happen, with these undesireable results.

Of course, if one should always start setUp() with a call to parent::setUp(), a short note to that effect in the appropriate place(s) could save those who don't know or remember to do this some time and frustration.

Dear contributor,

thanks to the hard work by @belanur, @starikovm, @trueromio, and others, the changes outlined in #471 (comment) have been implemented.

This repository, https://github.com/sebastianbergmann/phpunit-documentation, is now archived and read-only. The documentation for PHPUnit version prior to PHPUnit 7.0 will no longer be changed or updated. It is still hosted at

• Multiple HTML files: https://phpunit.de/manual/6.5/en/index.html
• Multiple HTML files (in a .tar.bz2 archive): https://phpunit.de/manual/current/en/download.tar.bz2
• Single HTML file: https://phpunit.de/manual/current/en/phpunit-book.html
• PDF: https://phpunit.de/manual/current/en/phpunit-book.pdf
• ePub: https://phpunit.de/manual/current/en/phpunit-book.epub

Simply replace 6.5 with the version number you are looking for. Simply replace en with fr, pt_br, ja, or zh_cn to access the French, Brazilian Portuguese, Japanese, or Simplified Chinese translation, respectively.

Starting with the documentation for PHPUnit 7.0, the PHPUnit documentation is hosted at https://phpunit.readthedocs.io/.

• The English documentation for PHPUnit is now maintained in the phpunit-documentation-english project
• The French documentation for PHPUnit is now maintained in the phpunit-documentation-french project
• The Brazilian Portuguese documentation for PHPUnit is now maintained in the phpunit-documentation-brazilian-portuguese project
• The Japanese documentation for PHPUnit is now maintained in the phpunit-documentation-japanese project
