While you're in here, some of these tests indent the multi-line strings and some
don't. Do you mind making them consistent?

(I personally prefer indented, but I'm happy either way.)

Done.

 
     // Should be in global package cache.
     d.dir(cachePath, [
       d.dir('global_packages', [
         d.matcherFile('foo.lock', contains('1.0.0'))
       ])
     ]).validate();
   });
 }
