junit - How to unit test a method that runs into an infinite loop for some input? -

-

this question occurred mind , want ask here.

the case intentional, write loop runs infinitely. how go unit testing it?

i ask because, situation may occur anywhere in code. method delegates several other methods, , want know

  • how ran infinite loop
  • what set of input caused it
  • call method (from method) has caused this

i have no code written this. question purely knowledge sake if situation arises in future. please respond.

how unit test method runs infinite loop input?

you can test opposite: "how unit test method method not run longer xxxx milliseconds input". if test fails may have found candidate infinite loop.

nunit 2.5 has timeoutattribute makes test fail if test takes longer given amount of milliseconds.

why need use because printers using tprinter prints weird hieroglyph @ beginning of printable area. my problem if send commands, nothing happens. esc e (#27 #69) - sending escape sequence didn't work expected. removed first letter , rest of string made bold. eg. hello -> ello . after changed esc e esc (#27 #69 #27), worked fine. example managed figure out, but... trying select character table "esc t n" (#27 #116 n), make "õäöü" work. command doesn't work. nothing happens! , command supported esc/p, esc/p 2 , 9-pin esc/p, should work fine. manual can found here . if has ever needed use esc/p commands maybe 1 can shed light how work them! thanks in advance! edit: in previous post asked more or less same question though answers how did send commands printer. (i'll change question there according answers!) i accepted ken's answer, because claimed way transferred commands wasn't best , got work escape command. problem after t...
