apps/testing README file ======================== The apps/testing directory is used to build NuttX-specific tests and to include external testing frameworks. There is overlap between what you will find in apps/examples and apps/testing in the sense that there are also tests in apps/examples as well. Those tests, however, can also be used to illustrate usage of a NuttX feature. Most of the tests in apps/testing, on the other hand, are pure tests with little value as usage examples. testing/cxxtest =============== This is a test of the C++ standard library. At present a port of the uClibc++ C++ library is available. Due to licensing issues, the uClibc++ C++ library is not included in the NuttX source tree by default, but must be installed (see the README.txt file in the uClibc++ download package for installation). The uClibc++ test includes simple test of: - iostreams, - STL, - RTTI, and - Exceptions Example Configuration Options ----------------------------- CONFIG_TESTINGCXXTEST=y - Eanbles the example CONFIG_TESTINGCXXTEST_CXXINITIALIZE=y - By default, if CONFIG_HAVE_CXX and CONFIG_HAVE_CXXINITIALIZE are defined, then this example will call the NuttX function to initialize static C++ constructors. This option may be disabled, however, if that static initialization was performed elsewhere. Other Required Configuration Settings ------------------------------------- Other NuttX setting that are required include: CONFIG_HAVE_CXX=y CONFIG_HAVE_CXXINITIALIZE=y CONFIG_UCLIBCXX=y Additional uClibc++ settings may be required in your build environment. testing/fstest ============== This is a generic file system test that derives from testing/nxffs. It was created to test the tmpfs file system, but should work with any file system provided that all initialization has already been performed prior to starting the test. This test a a general test for any file system, but includes some specific hooks for the SPIFFS file system. * CONFIG_TESTING_FSTEST: Enable the file system example * CONFIG_TESTING_FSTEST_MAXNAME: Determines the maximum size of names used in the filesystem * CONFIG_TESTING_FSTEST_MAXFILE: Determines the maximum size of a file * CONFIG_TESTING_FSTEST_MAXIO: Max I/O, default 347. * CONFIG_TESTING_FSTEST_MAXOPEN: Max open files. * CONFIG_TESTING_FSTEST_MOUNTPT: Path where the file system is mounted. * CONFIG_TESTING_FSTEST_NLOOPS: Number of test loops. default 100 * CONFIG_TESTING_FSTEST_VERBOSE: Verbose output testing/nxffs ============= This is a test of the NuttX NXFFS FLASH file system. This is an NXFFS stress test and beats on the file system very hard. It should only be used in a simulation environment! Putting this NXFFS test on real hardware will most likely destroy your FLASH. You have been warned. testing/ostest ============== This is the NuttX 'qualification' suite. It attempts to exercise a broad set of OS functionality. Its coverage is not very extensive as of this writing, but it is used to qualify each NuttX release. The behavior of the ostest can be modified with the following settings in the boards//configs//defconfig file: * CONFIG_NSH_BUILTIN_APPS Build the OS test example as an NSH built-in application. * CONFIG_TESTING_OSTEST_LOOPS Used to control the number of executions of the test. If undefined, the test executes one time. If defined to be zero, the test runs forever. * CONFIG_TESTING_OSTEST_STACKSIZE Used to create the ostest task. Default is 8192. * CONFIG_TESTING_OSTEST_NBARRIER_THREADS Specifies the number of threads to create in the barrier test. The default is 8 but a smaller number may be needed on systems without sufficient memory to start so many threads. * CONFIG_TESTING_OSTEST_RR_RANGE During round-robin scheduling test two threads are created. Each of the threads searches for prime numbers in the configurable range, doing that configurable number of times. This value specifies the end of search range and together with number of runs allows to configure the length of this test - it should last at least a few tens of seconds. Allowed values [1; 32767], default 10000 * CONFIG_TESTING_OSTEST_RR_RUNS During round-robin scheduling test two threads are created. Each of the threads searches for prime numbers in the configurable range, doing that configurable number of times. testing/smart ============= This is a test of the SMART file system that derives from testing/nxffs. * CONFIG_TESTING_SMART: - Enable the SMART file system example * CONFIG_TESTING_SMART_ARCHINIT: The default is to use the RAM MTD device at drivers/mtd/rammtd.c. But an architecture-specific MTD driver can be used instead by defining CONFIG_TESTING_SMART_ARCHINIT. In this case, the initialization logic will call smart_archinitialize() to obtain the MTD driver instance. * CONFIG_TESTING_SMART_NEBLOCKS: When CONFIG_TESTING_SMART_ARCHINIT is not defined, this test will use the RAM MTD device at drivers/mtd/rammtd.c to simulate FLASH. In this case, this value must be provided to give the nubmer of erase blocks in MTD RAM device. The size of the allocated RAM drive will be: CONFIG_RAMMTD_ERASESIZE * CONFIG_TESTING_SMART_NEBLOCKS * CONFIG_TESTING_SMART_MAXNAME: Determines the maximum size of names used in the filesystem * CONFIG_TESTING_SMART_MAXFILE: Determines the maximum size of a file * CONFIG_TESTING_SMART_MAXIO: Max I/O, default 347. * CONFIG_TESTING_SMART_MAXOPEN: Max open files. * CONFIG_TESTING_SMART_MOUNTPT: SMART mountpoint * CONFIG_TESTING_SMART_NLOOPS: Number of test loops. default 100 * CONFIG_TESTING_SMART_VERBOSE: Verbose output testing/smart_test ================== Performs a file-based test on a SMART (or any) filesystem. Validates seek, append and seek-with-write operations. * CONFIG_TESTING_SMART_TEST=y Dependencies: * CONFIG_NSH_BUILTIN_APPS=y: This test can be built only as an NSH command Source: NuttX Author: Ken Pettit Date: April 24, 2013 Performs a file-based test on a SMART (or any) filesystem. Validates seek, append and seek-with-write operations. Usage: flash_test mtdblock_device Additional options: --force to replace existing installation testing/smp =========== This is a simple test for SMP functionality. It is basically just the pthread barrier test with some custom instrumentation. testing/unity ============= Unity is a unit testing framework for C developed by ThrowTheSwitch.org: http://www.throwtheswitch.org/unity
