Can't find file to patch at input line 11, File to patch:? I got an error message on module installation simpletest


  SimpleTest could not be installed. Must apply core patch, please see INSTALL.txt. (Currently using SimpleTest code addition Not-found)


Then by the instruction provided by INSTALL.txt I run the command 


  ioss@ioss-System-Product-Name:~$ patch -p0 &lt; /var/www/Drupal/beeone/sites/all/modules/simpletest/D6-core-simpletest.patch 


Then I got error below

can't find file to patch at input line 11
Perhaps you used the wrong -p or --strip option?

File to patch:
The patch is trying to alter the install.php file that comes with Drupal, but it doesn't find it. That file is normally removed, once Drupal has been installed. 

What the command line is prompting for is the name of the file to patch, in the case has been renamed, or moved in a different directory.

Keep in mind that the SimpleTest module should not be installed in a production server, but in a development site.
