c# - Unit testing - how to emulate a delay -

-

we've got large c# solution multiple apis, svcs , on. usual sort of enterprisy mess after same code has been worked on years multiple people.

anyway! have ability call external service , have unit tests in place use moq stub implementation of services interface.

it happens there can large delay in calling external service , it's not can control (it's gds interface).

we've been working on way streamline user experience part of our platform.

the problem is, stub doesn't @ - , of course, lightening fast, compared real thing.

we want introduce random delay 1 of stubbed methods, cause call take between 10 , 20 seconds complete.

the naive approach do:

int sleeptimer = random.next(10, 20); thread.sleep(sleeptimer * 1000);

but gives me bad feeling. other ways people have of solving kind of scenario, or thread.sleep ok use in context ?

thanks time!

edit, answer of comments:

basically, don't want call live external service our test suite, because costs money , other business problems.

however, want test our new processes work well, when there's variable delay in essential call external service.

i love explain exact process, i'm not allowed to.

but yeah, summary our test needs ensure long running call external service doesn't obstruct rest of flow; , need ensure other tasks don't kind of race conditions, depend on result of call.

i agree calling unit-test incorrect now!

i wish write custom appender on basis of outputstreamappender . wrote following class package tests; import java.io.ioexception; import java.io.outputstream; import ch.qos.logback.core.outputstreamappender; public class myappender<e> extends outputstreamappender<e> { public myappender() { system.out.println("myappender created"); setoutputstream(new outputstream() { @override public void write(int b) throws ioexception { throw new unsupportedoperationexception(); } }); } } then wrote following runner: package tests; import org.slf4j.loggerfactory; import ch.qos.logback.classic.logger; public class runner { private static final logger log = (logger) loggerfactory.getlogger(runner.class); public static void main(string[] args) { //log.addappender(new myappender<iloggingevent>()); log.info("hello world"); } } finall...

java - UML - How would you draw a try catch in a sequence diagram? -

-
Image
is there standard way of drawing try catch sequence diagrams? i've made attempt based on this feel end result doesn't feel right. code diagram based around: public static void save () { try { filehandle filehandle = gdx.files.external(file); filehandle.writestring(boolean.tostring(constantshandler.soundenabled)+"\n", false); (int = 0; < 5; i++) { filehandle.writestring(integer.tostring(constantshandler.highscores[i])+"\n", true); } } catch (throwable e) { } } my attempt note: know still need add loop. that's ok. fragments meant show conditional control flow in sequence diagram. superstructures puts limitations on use of fragments (see pp. 467 of ss2.1.1). should use critical region try part above. , option catch . however, keep telling can take quite freedom in using uml. it's language , such changes in life time. long reader ge...
