Following make targets are available
This will compile and link the tests.
This will execute all the tests.
This will build and run tests.
The following make variables may help you in testing:
- V / VERBOSE - run tests with a lot of output
- TIMEOUTFACTOR=nn - increase test timeout nn times.
You can pass the following 2 environment variables to "make run":
- make run SIMULATOR=qemu-sh4
If you need to test just a subset of all test, delete subdirectories
you do not need.
The structure of this test system is:
test/ toplevel dir containing common test code
test/Rules.mak Common build code
test/Test.mak Runtime test make code
test/subdir/ code specific to a subsystem is stored in a subdir
test/subdir/Makefile.in describe the tests to run
test/subdir/Makefile test entry point, includes needed upper-level
makefiles plus Makefile.in
test/subdir/*.c the tests
Each subdir has a Makefile (same for any subdir) that must include in strict order:
- the upper-level Rules.mak file
- the Makefile.in
- the upper-level Test.mak file
Makefile.in may be used to define the TESTS and TESTS_DISABLED variables.
If you do not, TESTS is built automatically based upon all the .c files in the subdir.
TESTS := foo
TESTS_DISABLED := bar
Each test must use a similar .c name; so the "foo" test needs a "foo.c".
Additionally, the following options further control specific test behavior:
CFLAGS_foo := extra cflags to use to compile test
LDFLAGS_foo := extra ldflags to use to link test
OPTS_foo := extra options to pass to test
RET_foo := expected exit code of test; default is 0
WRAPPER_foo := execute stuff just before test
Or to control all tests in a subdir:
EXTRA_CLEAN := extra files to remove in the clean target
EXTRA_DIRS := extra directories to remove in the clean target
EXTRA_CFLAGS := -DFOO
EXTRA_LDFLAGS := -lpthread
If you want to compare the output of a test with known good output, then just
create a local file named "foo.out.good" and the output generated by the test
"foo" will be automatically stored in "foo.out" and compared to "foo.out.good".
