Take the 2-minute tour ×  Consider the following scenario (this
is not production code):   class MyClass {     public function
myMethod() {         // create a directory         $path =
sys_get_temp_dir() . '/' . md5(rand());
if(!mkdir($path)) {             throw new Exception("mkdir()
failed.");          // create a file in that folder
$myFile = fopen("$path/myFile.txt", "w");         if(!$myFile) {
throw new Exception("Cannot open file handle.");  Right, so
whats the problem? Code coverage reports that this line is not
covered:   Which is correct, but since I'm creating the folder
above logically it would seem impossible for the fopen() to fail
unless (maybe in extreme circumstances like disk at 100%).  I
could ignore the code from code coverage but thats kind of
cheating. Is there any way I can mock the file system so that it
can recognise myFile.txt and mock the file system unable to
create the file?  share|improve this question add comment  3
