4 Following make targets are avaialable
8 This will compile and link the tests.
12 This will execute all the tests.
17 This will build and run tests.
19 The following make variables may help you in testing:
21 - UCLIBC_ONLY - only run tests against uClibc
22 - GLIBC_ONLY - only run tests against glibc
23 - V / VERBOSE - run tests with a lot of output
24 - TEST_INSTALLED_UCLIBC - Test installed libraries
25 under /lib and /usr/lib.
26 - TIMEOUTFACTOR=nn - increase test timeout nn times.
27 At least REGEX_OLD + regex/tst-regex2 needs it increased.
29 So, to just run the uClibc tests, try this:
30 make check UCLIBC_ONLY=1
32 If you need to test just a subset of all test, delete subdirectories
35 As of 2009-07, build machinery does not track dependencies on uclibc.
36 If you edit a header and re-run "make compile", it does not re-install it
37 into ../install_dir. If you delete ../install_dir, "make compile"
38 rebuilds uclibc as needed and re-installs ../install_dir,
39 but still does not rebuild testcases.
40 (You can work around it by "touch */*.c" for now).
46 The structure of this test system is:
47 test/ toplevel dir containing common test code
48 test/Rules.mak Common build code
49 test/Test.mak Runtime test make code
50 test/subdir/ code specific to a subsystem is stored in a subdir
51 test/subdir/Makefile.in describe the tests to run
52 test/subdir/Makefile test entry point, includes needed upper-level
53 makefiles plus Makefile.in
54 test/subdir/*.c the tests
56 Each subdir has a Makefile (same for any subdir) that must include in strict order:
57 - the upper-level Rules.mak file
59 - the upper-level Test.mak file
60 Makefile.in may be used to define the TESTS and TESTS_DISABLED variables.
61 If you do not, TESTS is built automatically based upon all the .c files in the subdir.
64 Each test must use a similar .c name; so the "foo" test needs a "foo.c".
66 Additionally, the following options further control specific test behavior:
67 CFLAGS_foo := extra cflags to use to compile test
68 DODIFF_foo := compare the output of the glibc and uClibc tests (see below)
69 LDFLAGS_foo := extra ldflags to use to link test
70 OPTS_foo := extra options to pass to test
71 RET_foo := expected exit code of test; default is 0
72 WRAPPER_foo := execute stuff just before test
74 Or to control all tests in a subdir:
75 EXTRA_CLEAN := extra files to remove in the clean target
76 EXTRA_DIRS := extra directories to remove in the clean target
78 EXTRA_LDFLAGS := -lpthread
82 If you want to compare the output of a test with known good output, then just
83 create a local file named "foo.out.good" and the output generated by the test
84 "foo" will be automatically stored in "foo.out" and compared to "foo.out.good".
