</span>That's what inheritance is for:<br>
<br>
* Define a class which inherits from unittest.TestCase. Have one of its<br>
methods (probably ‘setUp’) do the common processing you want for every<br>
test case instance.<br>
<br>
* Define your test case classes to inherit from the above class.<br>
<br>
class unittest.TestCase(object)<br>
class foo.Foo_BaseTestCase(unittest.<wbr>TestCase)<br>
class foo.LoremIpsum_TestCase(foo.<wbr>Foo_BaseTestCase)<br>
class foo.DolorSitAmet_TestCase(foo.<wbr>Foo_BaseTestCase)<br>
<br>
That way, the special set-up you speak of will be defined in one place;<br>
any other class that needs it simply refers (by inheritance) to that<br>
same place and doesn't need to define it again.<br>
