-    -i <implementations>

         Set PyMuPDF implementations to test.
         <implementations> must contain only these individual characters:
              'r' - rebased.
              'R' - rebased without optimisations.
             Default is 'r'. Also see `PyMuPDF:tests/run_compound.py`.
     
+    -i <install_version>
+        Set version installed by the 'install' command.
+    
     -k <expression>
         Specify which test(s) to run; passed straight through to pytest's `-k`.
         For example `-k test_3354`.
