**用NDK编译gtest库：**

1. gtest代码pull下来后，创建jni目录，将googleTest下文件放到jni目录下

2. 在jni目录下创建Application.mk和Android.mk文件

Application.mk

##Application.mk
    #######################################################################
    APP_ABI := armeabi-v7a
    APP_MODULES := libgtest libgtest_main
    APP_STL := stlport_static  
    APP_PLATFORM := android-18

Android.mk

PROJECT := gtest
    LOCAL_PATH:= $(call my-dir)
    PRJ_TOP := $(call my-dir)
    include $(PRJ_TOP)/googletest/Android.mk

3. 在jni/googletest目录下创建Android.mk

Android.mk

##Android.mk
    #######################################################################
    # gtest lib target
    
    LOCAL_PATH := $(call my-dir)
    
    include $(CLEAR_VARS)
    
    LOCAL_CPP_EXTENSION := .cc
    
    LOCAL_SRC_FILES := src/gtest-all.cc
    
    #LOCAL_C_INCLUDES := $(libgtest_target_includes)
    LOCAL_C_INCLUDES := $(LOCAL_PATH)/src
    LOCAL_C_INCLUDES := $(LOCAL_PATH)/include
    
    LOCAL_MODULE := libgtest
    LOCAL_MODULE_TAGS := eng
    
    include $(BUILD_STATIC_LIBRARY)
    
    
    #######################################################################
    # gtest_main lib target
    
    include $(CLEAR_VARS)
    
    LOCAL_CPP_EXTENSION := .cc
    
    LOCAL_SRC_FILES := src/gtest_main.cc
    
    LOCAL_C_INCLUDES := $(LOCAL_PATH)/src
    LOCAL_C_INCLUDES := $(LOCAL_PATH)/include
    
    LOCAL_STATIC_LIBRARIES := libgtest
    
    LOCAL_MODULE := libgtest_main
    LOCAL_MODULE_TAGS := eng
    
    include $(BUILD_STATIC_LIBRARY)

4. ndk-build编译生成libgtest.a和libgtest\_main.a

**测试程序编译链接gtest库：**

1. 将交叉编译好的gtest库libgtest.a和libgtest\_main.a放到测试代码目录

2. 编写测试程序代码test.cpp

#include "gtest/gtest.h"
    #include "downloader_interface.h"
    
    TEST(TestDemo, DL_CreateHandle)
    {
        DLHandle handle = DL_CreateHandle();
        ASSERT_NE(handle, (void*)NULL);
    
        DL_CloseHandle(handle);
    }

3. 编写Android.mk

LOCAL_PATH:=$(call my-dir)
    
    include $(CLEAR_VARS)
    LOCAL_MODULE := gtest_download
    LOCAL_SRC_FILES := test.cpp
    
    LOCAL_C_INCLUDES += $(LOCAL_PATH)/../include
    LOCAL_C_INCLUDES += $(LOCAL_PATH)/../src
    
    LOCAL_CFLAGS := -D__STDC_CONSTANT_MACROS  -DHAVE_PTHREADS
    LOCAL_LDFLAGS  += -pie
    LOCAL_LDFLAGS  += -L$(LOCAL_PATH)/
    LOCAL_LDLIBS +=  -llog -lz -lm
    LOCAL_LDLIBS +=  -lgtest -lgtest_main
    LOCAL_STATIC_LIBRARIES += download_a
    include $(BUILD_EXECUTABLE)
    
    $(call import-module,third_party/googletest)

**gtest单元测试命令：**

./gest\_program --gtest\_filter=dl\_test.dl\_http
