uncle bob says: "defensive programming, in non-public apis, smell, , symptom, of teams don't tdd." i wondering how tdd can avoid (internal) function used in unintended way? think tdd can´t avoid it. merely shows function used correctly because calling function covered it´s passing unit tests. when developing new feature using (undefensive) function feature developed tdd. unintended use of function fail new features tests. so using tdd drive new features force correcty use (internal) functions. do think meant uncle bob´s tweet? so using tdd drive new features force correctly use (internal) functions. exactly. keep in mind subtle "gap" here: should use tdd write (unit) tests test contract of public methods. not care implementation of these methods - internal implementation detail. therefore: if "new" code uses existing method in unintended way "told" because exception thrown or receive unexpected result. that

my question similar question linq join multiple conditions in on clause , other similar question either talk having properties map respective conditions or writing query without join from t1 in projects t2 in tasks.where(x => t1.projectid == x.projectid && x.completed == true) .defaultifempty() select new { t1.projectname, t2.taskname } suppose if go first way of writing i.e. on new { t1.projectid, secondproperty = true } equals new { t2.projectid, secondproperty = t2.completed } j1 that gets converted , (&&). want or (||) in join form (2nd way of writing). thanks in advance. if want perform join projectid , have || on secondproperty must join 1 field , add where clause: from t1 in projects join t2 in tasks on t1.projectid equals t2.projectid t1.secondproperty || t1.secondproperty == t2.completed select new { t1, t2 } wiki

i having dialog in behavior. setting behavior default , way dialog available on start. i found default topics basic channel ( http://doc.aldebaran.com/2-1/nao/basic_channel_conversation.html ) initialized 'run_dialog_dev/.' (i guess basic channel or part of factory state of robot). so there way put dialog(topic) part of default ones without putting in behavior, adding topic robot. , topic auto included in 'run_dialog_dev/.'. to have dialog topic initialized 'run_dialog_dev/.' alongside basic channel should declare 'collaborative dialog' (see choregraphe documentation ). when creating topic, make sure tick checkbox @ bottom of window. your choregraphe project won't have contain behavior, can have contain dialog. wiki
