sage tests

[ph h]

Dear All,

Please advise if there are any documentation on the tests performed in the Makefile:

TESTALL = ./sage -t --all
PTESTALL = ./sage -t -p --all

# Flags for ./sage -t --all.
# When the documentation is installed, "optional" also includes all tests marked 'sagemath_doc_html',
# see https://trac.sagemath.org/ticket/25345, https://trac.sagemath.org/ticket/26110, and
# https://trac.sagemath.org/ticket/32759
TESTALL_FLAGS = --optional=sage,optional,external

test: all
        $(TESTALL) --logfile=logs/test.log

check: test

testall: all
        $(TESTALL) $(TESTALL_FLAGS) --logfile=logs/testall.log

testlong: all
        $(TESTALL) --long --logfile=logs/testlong.log

testalllong: all
        $(TESTALL) --long $(TESTALL_FLAGS) --logfile=logs/testalllong.log

ptest: all
        $(PTESTALL) --logfile=logs/ptest.log

A simple 'make test' ended with:

There was also this message, "cysignals fork: Cannot allocate memory" in the test.log:

python3(_PyRun_SimpleFileObject+0x326)[0x47481a]

cysignals fork: Cannot allocate memory

**********************************************************************
sage -t --random-seed=155907586838286474500183055218837555767 src/sage/matrix/matrix_modn_dense_double.pxd
    [0 tests, 0.00 s]

What does that "cysignals fork: Cannot allocate memory" mean?

Is there anything else besides 'pytest' that need be installed to run all these tests?

Would these two cover all test cases:

testalllong: all
        $(TESTALL) --long $(TESTALL_FLAGS) --logfile=logs/testalllong.log

ptest: all
        $(PTESTALL) --logfile=logs/ptest.log

Thank you for your help.
