GoogleTest NDK 编译

下载 googleTest 源码

从github上直接clone 最新的googleTest源码：
创建一个本地路径，如：

c:/test/GoogleTest

然后进入到该路径下直接clone最新的代码：

git clone https://github.com/google/googletest.git

NDK编译

当前的目录结构：

c:/test/GoogleTest/googletest
c:/test/GoogleTest/googlemock

我们进入到googletest子路径中：

cd c:/test/GoogleTest/googletest
mdkir jni

创建jni路径后，我们就需要对应的Android.mk 和 Application.mk去调用NDK进行编译。
可以从如下地址中下载NDK reference其jni路径中的Android.mk及Application.mk并拷贝到本地的路径中：

c:/test/GoogleTest/googletest/jni

拷贝完成后进入到如下路径并执行ndk-build进行编译：

cd c:/test/GoogleTest/googletest/
ndk-build

如果还未配置ndk，那就需要先去安装ndk并且配置到系统环境变量中去。

当编译完成之后，会jni同级路径下生成obj文件夹，在此路径下回生成若干平台的LIB文件，当然可以根据需要修改Android.mk去生成对应的动态链接库或者静态链接库等。

其Android.mk 参考如下：

Google Test的使用

Google Test如何使用本篇便不再赘述，当编写了大量的测试用例进行测试时，有时我们需要仅针对部分用例进行验证。

针对部分用例测试

假设我们编写了如下测试用例：

------------------------------------------------------
TEST(case1, functionA_test） {
....
}

TEST(case1, functionB_test） {
....
}

TEST(case2,  functionA_test) {
.....
}

TEST(case2, functionB_test){
....
}

TEST(case3, functionA_test) {
....
}

int main(int argc, char **argv) {
  ::testing::InitGoogleTest(&argc, argv);
  return RUN_ALL_TESTS();
}
-------------------------------------------------

如果仅需要运行case2模块相关用例，编译出来的可执行文件为test.exe,那么：

//运行所有case2的用例
test.exe --gtest_filter=case2.*
//运行某个具体用例
test.exe --gtest_filter=case3.functionA_test

此时我们便可以实现按照实际需求进行用例验证。
