Outline of test categories:
|
||
|
|
||
|
The conform/ tests:
|
||
|
-------------------
|
||
|
These tests should be non-interactive unit-tests that verify a single
|
||
|
feature is behaving as documented. See conform/ADDING_NEW_TESTS for more
|
||
|
details.
|
||
|
|
||
|
Although it may seem a bit awkward; all the tests are built into a
|
||
|
single binary because it makes building the tests *much* faster by avoiding
|
||
|
lots of linking.
|
||
|
|
||
|
Each test has a wrapper script generated though so running the individual tests
|
||
|
should be convenient enough. Running the wrapper script will also print out for
|
||
|
convenience how you could run the test under gdb or valgrind like this for
|
||
|
example:
|
||
|
|
||
|
NOTE: For debugging purposes, you can run this single test as follows:
|
||
|
$ libtool --mode=execute \
|
||
|
gdb --eval-command="b test_cogl_depth_test" \
|
||
|
--args ./test-conformance -p /conform/cogl/test_cogl_depth_test
|
||
|
or:
|
||
|
$ env G_SLICE=always-malloc \
|
||
|
libtool --mode=execute \
|
||
|
valgrind ./test-conformance -p /conform/cogl/test_cogl_depth_test
|
||
|
|
||
|
By default the conformance tests are run offscreen. This makes the tests run
|
||
|
much faster and they also don't interfere with other work you may want to do by
|
||
|
constantly stealing focus. CoglOnscreen framebuffers obviously don't get tested
|
||
|
this way so it's important that the tests also get run onscreen every once in a
|
||
|
while, especially if changes are being made to CoglFramebuffer related code.
|
||
|
Onscreen testing can be enabled by setting COGL_TEST_ONSCREEN=1 in your
|
||
|
environment.
|
||
|
|
||
|
The micro-bench/ tests:
|
||
|
-----------------------
|
||
|
These should be focused performance tests, ideally testing a
|
||
|
single metric. Please never forget that these tests are synthetic and if you
|
||
|
are using them then you understand what metric is being tested. They probably
|
||
|
don't reflect any real world application loads and the intention is that you
|
||
|
use these tests once you have already determined the crux of your problem and
|
||
|
need focused feedback that your changes are indeed improving matters. There is
|
||
|
no exit status requirements for these tests, but they should give clear
|
||
|
feedback as to their performance. If the framerate is the feedback metric, then
|
||
|
the test should forcibly enable FPS debugging.
|
||
|
|
||
|
The data/ directory:
|
||
|
--------------------
|
||
|
This contains optional data (like images) that can be referenced by a test.
|
||
|
|
||
|
|
||
|
Misc notes:
|
||
|
-----------
|
||
|
• All tests should ideally include a detailed description in the source
|
||
|
explaining exactly what the test is for, how the test was designed to work,
|
||
|
and possibly a rationale for the approach taken for testing.
|
||
|
|
||
|
• When running tests under Valgrind, you should follow the instructions
|
||
|
available here:
|
||
|
|
||
|
http://live.gnome.org/Valgrind
|
||
|
|
||
|
and also use the suppression file available inside the data/ directory.
