+# PAL Test Guide
+## Environment Setup
+Python 2.7.11
+If you cannot find Python 2.7.11 for your linux you can get it here [Python 2.7.11](https://launchpad.net/~fkrull/+archive/ubuntu/deadsnakes-python2.7)
+Install the needed Python modules on Windows like this:
+```
+python -m pip install tabulate
+python -m pip install pyserial
+python -m pip install -U mbed-ls
+python -m pip install shell
+python -m pip install pypiwin32
+```
+On Linux you install the same modules like this:
+```
+sudo pip install <module>
+```
+
+##Test Code files
+Each API has three files under Test/Unitest or Test/Conformance:
+
+* **pal_socket_test.c** Contains the test code in the form of functions. One function per test.
+* **pal_ socket _test_runner.c** Runs the test functions defined above.
+* **pal_ socket _test_main_mbedos.c** Main application that runs all the tests. May also have test specific initializations for the given target platform.
+
+Each API can also have a common utilities file under Test/Common
+**pal_socket_test_utils.c/.h** Utility functions that can be used in various pal_socket test apps.
+**pal_socket_test.c**
+Contains tests of the form:
+
+```
+#include "pal_socket.h"
+#include "unity.h"
+#include "unity_fixture.h"
+
+TEST(pal_socket, FunctionWhichReturnsLocalVariable_ShouldReturnTheCurrentCounterValue)
+{
+ //This should be true because setUp set this up for us before this test
+ TEST_ASSERT_EQUAL_HEX(0x5a5a, FunctionWhichReturnsLocalVariable());
+
+ //This should be true because we can still change our answer
+ Counter = 0x1234;
+ TEST_ASSERT_EQUAL_HEX(0x1234, FunctionWhichReturnsLocalVariable());
+}
+```
+**pal_ socket _test_runner.c**
+Looks like this:
+```
+#include "unity.h"
+#include "unity_fixture.h" // pal Socket API tests
+
+TEST_GROUP_RUNNER(pal_socket)
+{
+#if (PAL_INCLUDE || FindFunction_WhichIsBroken_ShouldReturnZeroIfItemIsNotInList_WhichWorksEvenInOurBrokenCode)
+ RUN_TEST_CASE(pal_socket, FindFunction_WhichIsBroken_ShouldReturnZeroIfItemIsNotInList_WhichWorksEvenInOurBrokenCode);
+#endif
+#if (PAL_INCLUDE || FindFunction_WhichIsBroken_ShouldReturnTheIndexForItemsInList_WhichWillFailBecauseOurFunctionUnderTestIsBroken)
+ RUN_TEST_CASE(pal_socket, FindFunction_WhichIsBroken_ShouldReturnTheIndexForItemsInList_WhichWillFailBecauseOurFunctionUnderTestIsBroken);
+#endif
+#if (PAL_INCLUDE || FunctionWhichReturnsLocalVariable_ShouldReturnTheCurrentCounterValue)
+ RUN_TEST_CASE(pal_socket, FunctionWhichReturnsLocalVariable_ShouldReturnTheCurrentCounterValue);
+#endif
+#if (PAL_INCLUDE || FunctionWhichReturnsLocalVariable_ShouldReturnTheCurrentCounterValueAgain)
+ RUN_TEST_CASE(pal_socket, FunctionWhichReturnsLocalVariable_ShouldReturnTheCurrentCounterValueAgain);
+#endif
+#if (PAL_INCLUDE || FunctionWhichReturnsLocalVariable_ShouldReturnCurrentCounter_ButFailsBecauseThisTestIsActuallyFlawed)
+ RUN_TEST_CASE(pal_socket, FunctionWhichReturnsLocalVariable_ShouldReturnCurrentCounter_ButFailsBecauseThisTestIsActuallyFlawed);
+#endif}
+```
+
+
+**pal_ socket _test_main_mbedos.c**
+This can vary a lot from platform to platform and test to test, but will contain lines like the following to run the tests:
+```
+extern "C" int UnityMain(int argc, const char* argv[], void (*runAllTests)(void));
+extern "C" void TEST_pal_socket_GROUP_RUNNER(void);
+
+ // Run a group of tests
+ UnityMain(0, argv, TEST_pal_socket_GROUP_RUNNER);
+```
+
+
+## Test makefile framework
+**makefile** – Master make file. It has an entry for each platform target. Includes all_tests.mk.
+Configuration specific defines are declared as follows and converted to compilation defines on the compilation command line.
+**TARGET_CONFIGURATION_DEFINES:= HAS_RTOS HAS_FS**
+They can be also be used to as conditionals in the make file as shown in all_tests.mk
+```
+include make_platform.mk
+
+
+.PHONY: all clean check
+
+#====================================================
+# Platform mbed-os
+TARGET_PLATFORM:=mbedosClassic
+TARGET_CONFIGURATION_DEFINES:= HAS_RTOS
+all: mbedosClassic_all
+check: mbedosClassic_check
+clean: mbedosClassic_clean
+include all_tests.mk
+#====================================================
+# Platform morpheus
+TARGET_PLATFORM:=mbedOS
+TARGET_CONFIGURATION_DEFINES:= HAS_RTOS
+all: mbedOS_all
+check: mbedOS_check
+clean: mbedOS_clean
+include all_tests.mk
+#====================================================
+```
+**make_platform.mk** – Detects the make platform (Windows, Linux) and sets various definitions accordingly. These are referred to by other make files in order to keep them platform independent.
+**all_tests.mk** – contains an entry for each test application to be built. Included by all target platform make files. It looks like this:
+```
+#====================================================
+PROJECT=pal_socket
+TYPE=Unity
+
+$(PROJECT)_ADDITIONAL_ SOURCES:=
+
+include BUILD_TEST.mk
+#====================================================
+ifeq ($(findstring HAS_RTOS,$(TARGET_CONFIGURATION_DEFINES)),HAS_RTOS)
+PROJECT=pal_rtos
+TYPE=Unitest
+
+$(PROJECT)_ADDITIONAL_SOURCES:=Source/PAL-Impl/Modules/RTOS/$(PROJECT).c \
+ Source/PAL-Impl/Modules/RTOS/$(PROJECT)_static_definitions_sample.c \
+ Source/Port/Reference-Impl/mbedOS/pal_plat_rtos.c
+
+
+include BUILD_TEST_$(TARGET_PLATFORM).mk
+endif
+#====================================================
+```
+**BUILD_TEST_BUILD_TEST_mbedOS.mk, BUILD_TEST_FreeRTOS.mk** – Target platform specific make definitions and rules. Defines targets for building the tests. Included for each test that is to be built.
+##Usage:
+###Make all tests for all platforms:
+**make**
+or make all tests for a specific platform:
+**make mbedOS_all**
+**make FreeRTOS_all**
+
+### To make and run one set of tests:
+**make mbedOS_pal_socket**
+
+### To make and run only one test from a set:
+**make mbedOS_pal_socket** PAL_TEST=”FindFunction_WhichIsBroken_ShouldReturnZeroIfItemIsNotInList_WhichWorksEvenInOurBrokenCode”
+To make a binary that just runs two tests from a set:
+**make mbedOS_pal_socket PAL_TEST=”FindFunction_WhichIsBroken_ShouldReturnZeroIfItemIsNotInList_WhichWorksEvenInOurBrokenCode FindFunction_WhichIsBroken_ShouldReturnTheIndexForItemsInList_WhichWillFailBecauseOurFunctionUnderTestIsBroken”**
+Note: If you change the argument PAL_TEST, then you will need to force a rebuild with –B.
+
+### To run all tests:
+**make mbedOS_check**
+### Run a specific test:
+**make mbedOS_check_pal_socket**
+
+## Eclipse
+It is possible to use the Build command from eclipse.
+First set it up to run make as follows. Note that the build directory points to Test:
+
+
+
+You can control which target you build in the next tab by changing all and clean.
