michael feathers, in working legacy code , on pages 13-14 mentions: a unit test takes 1/10th of second run slow unit test... if [unit tests] don't run fast, aren't unit tests. i can understand why 1/10th second slow if 1 has 30,000 tests, take close hour run. however, mean 1/11th of second better? no, not (as it's 5 minutes faster). hard fast rule isn't perfect. thus when considering how slow slow unit tests, perhaps should rephrase question. how long long developer wait unit test suite complete? to give example of test speeds. take @ several mstest unit test duration timings: 0.2637638 seconds 0.0589954 0.0272193 0.0209824 0.0199389 0.0088322 0.0033815 0.0028137 0.0027601 0.0008775 0.0008171 0.0007351 0.0007147 0.0005898 0.0004937 0.0004624 0.00045 0.0004397 0.0004385 0.0004376 0.0003329 the average 21 of these unit tests comes 0.019785 seconds. note slowest test due using microsoft moles mock/isolate file system. so example, if unit test su...

i doing code conversion javascript vb.net . stuck >>> operation. see sample code , attempt below: javascript: function test(a, b) { return (a << b) | (a >>> (32 - b)) } my attempt in vb.net: private function test(byval integer, byval b integer) integer return ((a << b) or (cushort(a) >> (32 - b))) end function what doing wrong? you should use cuint instead of cushort. cushort gives ushort 16-bit in size. in javascript bit operations done in 32-bit, a should converted 32-bit unsigned type — uinteger.

does perl have perl docs generator? java docs or php documenter? yes, it's called perldoc you write documentation in source, javadoc. briefly, "=item" bulleted item, e.g. function or parameter "=over" goes down level of identation, "=back" goes level. use "=cut" want switch perl code. here example of like: =item $b->add_module ( %options ) initialize module. module repository or branch of repository. valid options =over =item id id of module =item repo url of repository. subversion repositories supported. =back =cut sub add_module($%) { simply pass perl code through perldoc program formatted documentation.

is there method read specific line text file ? in api or apache commons. : string readline(file file, int linenumber) i agree it's trivial implement, it's not efficient specially if file big. string line = fileutils.readlines(file).get(linenumber); would do, still has efficiency problem. alternatively, can use: lineiterator = ioutils.lineiterator( new bufferedreader(new filereader("file.txt"))); (int linenumber = 0; it.hasnext(); linenumber++) { string line = (string) it.next(); if (linenumber == expectedlinenumber) { return line; } } this more efficient due buffer. take @ scanner.skip(..) , attempt skipping whole lines (with regex). can't tell if more efficient - benchmark it. p.s. efficiency mean memory efficiency
