Hi kilon, The tests instance variable is linked to the python grammar: top level items in an expression are probably tests, and, through the grammar, tests can be just atoms. So the tests instance variable doesn't means it is testing anything :) Thierry Le 30 janv. 2015 09:23, "kilon alios" <kilon.alios(a)gmail.com> a Ã©crit : > Ok so I tried to parse a very simple list like > > [ 67,12342,5 ] > > using Parse and explore , I can find these number by following this AST > (for example 67) > > PyFileInputNode>>statements: -> 1: PySimpleStmNode>>stmts: -> 1: > PyExprStmtNode>>tests: ->1: PyPowerNode>>atom: -> PyAtomNode>>list: -> 1: > PyPowerNode>>atom: -> PyPowerNode>>numberToken -> numberToken>>value -> 67 > > quite a structure, but the one thing I dont get is "tests" , why "tests" ? > > Does it tests something and if yes what ? >

Ok so I tried to parse a very simple list like [ 67,12342,5 ] using Parse and explore , I can find these number by following this AST (for example 67) PyFileInputNode>>statements: -> 1: PySimpleStmNode>>stmts: -> 1: PyExprStmtNode>>tests: ->1: PyPowerNode>>atom: -> PyAtomNode>>list: -> 1: PyPowerNode>>atom: -> PyPowerNode>>numberToken -> numberToken>>value -> 67 quite a structure, but the one thing I dont get is "tests" , why "tests" ? Does it tests something and if yes what ?

Writing a unit test using both an HTTP client and server is already a bit tricky sometimes, having it fail is always ugly. This is more a threading issue than anything else. I usually will do as you describe: rerun manually with a server where debug is enabled. It could be an idea to try to improve the situation, but it won't be easy. To enable a debug/continue style the client request should first not time out (which is not a good idea for unattended tests), then something should be done about the UI thread.
