I tried very hard, but failed. A typical result from sage -t -verbose:
256 tests in 28 items.
256 passed and 0 failed.
Test passed.
[8.1 s]
----------------------------------------------------------------------
The following tests failed:
sage -t -verbose
devel/sage/sage/schemes/elliptic_curves/ell_finite_field.py # Segfault
----------------------------------------------------------------------
Total time for all tests: 8.1 seconds
So *all* test passed, but nevertheless!
Another example:
113 tests in 17 items.
113 passed and 0 failed.
Test passed.
[6.2 s]
----------------------------------------------------------------------
The following tests failed:
sage -t -verbose devel/sage/sage/matrix/matrix_sparse.pyx # Segfault
----------------------------------------------------------------------
Total time for all tests: 6.2 seconds
[j...@vrede sage-4.3.rc0]$
But in another run:
[j...@vrede sage-4.3.rc0]$ ./sage -t -verbose
devel/sage/sage/matrix/matrix_sparse.pyx 2>&1 | tee -a test.log
[...]
113 tests in 17 items.
113 passed and 0 failed.
Test passed.
