I have some basic ideas about structuring that kind of test.
A) steped reporting, so each test reports the current step
B) collection of dependend test-items, having each test item as `step`
A requires extending the py.test reporting (but might be easy)
B requires extending the py.test test execution
Ali currently does acceptance testing for webapps using approach B.
The test collector is at
however it currently lacks dependend tests support.
We would also like to build acceptance testing tools for pygtk,
but those seem more fit for approach A.
We would need those for more complex applications,
Another interesting acceptance test approach is the way mercurial is
Its using sectioned shell scripts that can be matched with sectioned
expected output files.
I will do some more Work in those Areas after 17.03
