## Debugging test failures
@@ -36,21 +35,97 @@ You can run individual tests like this (from the sage subdirectory):
$ ./sage -t --long src/sage/geometry/riemannian_manifolds/parametrized_surface3d.py

-distraction:
+See https://www.sagemath.org/git-developer-guide/doctesting.html for more
+information and helpful tips.
+
+In particular, always focus on the *first failure* in a single test file; in
+many cases, subsequent failures (such as NameErrors) are due to the first
+failure and many of those will go away after fixing the first one.
+
+The following might be useful:
+
+ $ debian/rules EXTRA_SAGE_TEST_FLAGS=-f ptestlong
+
+It will run all previously-failed tests again, which is useful if you're on a
+mass test-fixing spree and forget to count which ones you've fixed. However
+this assumes that you didn't break any of the previously successful ones :p
+
+## Current test status
+
+You should get something roughly like the following. If you get different
+results, please add your experience to the below summary.
+
+First, remove ".frontend" from /usr/bin/ipython, this will fix 1 test. This is
+already fixed in ipython (Debian) git, we're just waiting for an upload.

+You can see infinity0's test failures here: https://people.debian.org/~infinity0/res/

+The _wip_hacky-test-fixes branch unbreaks some of these, but not sure that
+they're all a good idea.
