gtest ASSERT_TRUE和EXPECT

调用ASSERT_TRUE的函数，返回值类型定义必须是void，如果想返回别的类型，就用EXPECT_TRUE：

void abc::fun()

{

    ASSERT_TRUE(fun1());

}

bool abc::fun()

{

    bool result = fun1();

    EXPECT_TRUE(result );

    return result ;

}

ASSERT_TRUE is a macro. When expanded it will contain a branch like:

if (fun1() == false) {

   return;

}

This is how ASSERT_TRUE does a hard stop on failure, but it also means that your method bool abc::fun() now has a void return exit path, in conflict with its signature.

Possible fixes include don't use hard stop asserts:

bool abc::fun(){

    bool result = fun1();

    EXPECT_TRUE(result); //No return in expansion

                         //No hard stop!

    return result;

}

or change your methods return type if not needed:

void abc::fun(){

    ASSERT_TRUE(fun1()); //Hard stop on failure

}

or return by reference:

void abc::fun(bool &outResult){

   outResult = fun1();  //return result by reference

   ASSERT_TRUE(result);

}
