 # PHPUnit Trainee Story in Section Unit Test
 
+Learn how to write unit tests with the php [de facto](https://en.wikipedia.org/wiki/De_facto) standard implementation [PHPUnit](https://phpunit.de/).
+
 @todo
 * create empty unit test file
 * create validator that needs to get covered by a unit test
 * create a unit test that needs a real implementation to test against
+
+## Tasks
+
+* read [getting started](https://phpunit.de/getting-started.html)
+* install phpunit
+* execute phpunit (php vendor/bin/phpunit)
+* read [documentation](https://phpunit.de/documentation.html)
+* implement or extend a test using @dataProvider
+* implement or extend a test using @depends
+* implement or extend a test case using [fixtures](https://phpunit.de/manual/current/en/fixtures.html)
+* [organize](https://phpunit.de/manual/current/en/organizing-tests.html) your tests
+* generate code coverage report
+* watch the [videos](https://phpunit.de/presentations.html)
+
+## Answer Yourself the Following Questions
+
+* why is it good to use phpunit in vendor?
+* what is the phpunit.xml.dist good for?
+* why does it has the suffix ".dist"?
+* for what is the "bootstrap.php" good for?
+* can you make phpunit more verbose?
+* how to test exception throwing?
+    * can you validate the exception message also (if so, how)?
+* whats the difference between "assertSame" and "assertEquals"?
+* when to mark a test as incomplete?
+* when to mark a test as skipped?
+* when to mark a test as risky?
+* did you find any useful annotations?
+* is it easy to implement databased driven tests?
+    * what do you have to keep in mind?
+* what is unit testing good for?
+* can you extend phpunit easily?
+    * if you, could you find an extension you can implement?
