Hello Maxim,<br>
<br>
I thought I saw that you got a response to this question, but I can't
find it in the archives or on comp.lang.python...<br>
<br>
Anyway - patch can be used as a context manager, so one answer (if you
are using Python >= 2.5) is to use the with statement:<br>
<br>
<font class="fixed_width" face="Courier, Monospaced">with
patch('module.Class', spec=True)</font>
as MockClass:<br>
<br>
test1()<br>
MockClass.reset_mock()<br>
<br>
test2()<br>
MockClass.reset_mock()<br>
<br>
etc....<br>
<br>
All the best,<br>
<br>
