Ok ... yes ... I agree ... but it depends, so ... here is an example:

----------------------------------------------------------------------

Scenario 1 runs:

Test()


Scenario 2 runs:

Test1(), Test2(), Test3(), ...


Scenario 3 runs just

Testx() from Scenario2


Scenario 4:

My most complicated tests have to create a complex environment, create a
database and tables and so on and then a couple of tests are running.

For that I create the environment (create database) once for all tests
and destroy it afterwards.

But for each test I create tables in the database, fill them with
testdata and delete them afterwards.

There runs:

Setup(),
 SetupEach(), Test1(), TeardownEach()
 SetupEach(), Test2(), TeardownEach()
 ...
Teardown()


Scenario 5:

Most of the time (mostly while developing) I want to run just one of the
tests of Scenario 4. Then there has to run:

Setup(), SetupEach(), Testx(), TeardownEach(), Teardown()

Because I do not want to wait 5 minutes for each run of all tests of
Scenario 4.

----------------------------------------------------------------------

If we are able to run each scenario in a separate process, its up to the
author to separate the tests.

This is the sort of flexibility I found out that I need it in my daily
work with unittesting my code.

I do unittesting my code since a lot of years, t think about 2 years now
with Gambas.


Alles Gute
