unit testing - What is the difference between Classic and Constraint Model Assertions in Nunit? -

-

i learning nunit-2.6.3 reading documentation. having few doubts it.

what difference between classical model , constraint model assertion?

which model of assertions best one, , why?

the main difference syntactic. it's difference between (classic):

assert.areequal("expected", somestring);

and (constraint)

assert.that(somestring, is.equalto("expected"));

classic mode has been around longer , people believe it's more explicit , easier follow.

other people believe constraint based approach closer way might constraint if explaining else.

if you're getting started, constraint based assertions better ones learn, since they're direction nunit appears trying head in. they're closer fluentassertions. constraint based assertions has more explicit support extension through use of iresolveconstraint interface.

you should gain awareness of classic assertions since there's chance different places encounter code may use either depending on used first.

although syntax different, they're doing similar, if understand 1 set of assertions, converting them , forth pretty straightforward.

i'm using transactionscope rollback transaction fail bool errorreported = false; action<importerrorlog> newerrorcallback = e => { errorreported = true; errorcallback(e); }; using (var transaction = new transactionscope()) { foreach (importtaskdefinition task in taskdefinition) { loader.load(streamfile, newerrorcallback, task.destinationtable, processingtaskid); } if (!errorreported) transaction.complete(); } i'm sure there no transactionscope started ahead or after code. i'm using entity framework insert in db. regardless state of errorreported transaction never rolled in case of error. what missing ? transactionscope sets transaction.current . that's does. wants transacted must @ property. i believe ef each time connection opened reason. probably, connection open when scope installed. open connection inside of scope or enlist manually. ef has nasty "design decision": default opens
