perl - Not able to generate the code coverage result using Devel::Cover -

-

i tried find code coverage c4rgr.pl test file devel::cover. have .pm module sitting in same area. using perl -mdevel::cover c4rgr.pl, generates cover_db , has runs subdirectory inside.

inside runs subdirectory, versionated directory created every time run cover command , cover.13 obtained. cover.13 file (i think) has raw data code coverage results.

still, unable test results in html output format or on terminal screen.

this do:

  1. run perl -mdevel::cover c4rgr.pl

    here, c4rgr.pl uses .pm module sitting in same area.

  2. when run above command, runs test file no test coverage output shown in devel::cover html output obtained. nevertheless, cover.13 file created every time.

    cover.13 <- 1401378982.24872.12631 <- runs <- cover_db .

  3. can tell me how html file, please? able run dummy test same features , generate html file. actual test, not. or there way convert cover.13 file html not being done in case?

after running perl -mdevel::cover c4rgr.pl, run cover command. example:

cover -report html -outputdir cover_report

i've been using 2 methods render data. the first one: function name($id,$name){ return '<div id="'.$id.'">'.$name.'</div>'; } echo implode($pdo->query("select id,name user")->fetchall(pdo::fetch_func,'name')); the second one: $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); foreach($users $user){ echo name($user->id,$user->name); } i don't understand how pdo::fetch_func works. tried figure out. however, not well-documented. could please explain fetch mode? , also, 1 performs better? thank you. both methods wrong , have learn how use templates , how separate business logic presentation logic. $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); tpl::assign('users', $users); is code business logic part. then in template <?php foreach $users $row): ?> <div id="<?=$...
