   the RsvgHandle class and its methods, and its GObject properties.
 
-* `loading` - Tests that compressed and uncompressed SVGs are loaded
-  correctly even if read one or two bytes at a time.  This is
-  basically a test for the state machines in the loading code.
-
 * `crash` - Ensures that loading and parsing (but not rendering) a
   particular SVG doesn't crash or yield a GError.
   
 * `render-crash` - Ensures that rendering a loaded SVG doesn't crash.
 
-* `dimensions` - Loads an SVG, and tests that librsvg computes the
-  correct dimensions for the toplevel SVG element, or one of the
-  individual sub-elements.
-  
 * `errors` - Tests that errors are reported from the API when SVG
   files have deliberate errors in them.
