c – 为什么google测试ASSERT_FALSE在方法中不起作用,但EXPECT_FALSE起作用

error C2664:
‘std::basic_string<_Elem,_Traits,_Alloc>::basic_string(const
std::basic_string<_Elem,_Traits,_Alloc> &)’ : cannot convert parameter
1 from ‘void’ to ‘const std::basic_string<_Elem,_Traits,_Alloc> &’

它起作用,因为在我使用的任何TEST_F中.
但是EXPECT_FALSE在LibraryTest类和TEST_F方法中编译都很好.

如何在TEST_F使用的方法中使用ASSERT？

class LibraryTest : public ::testing::Test
{
public:
    string create_library(string libName)
    {
        string libPath = setup_library_file(libName);

        LibraryBrowser::reload_models();

        ASSERT_FALSE(library_exists_at_path(libPath));
        new_library(libName, libPath);
        ASSERT_TRUE(library_exists_at_path(libPath));
        EXPECT_FALSE(library_exists_at_path(libPath));
        return libPath;
    }
};

TEST_F(LibraryTest, libraries_changed)
{
    string libName = "1xEVTestLibrary";
    string libPath = create_library(libName);
}

void create_library(const string &libName, string &libPath) {
  libPath = ...
  ASSERT_FALSE(...)
}

并像这样使用它：

TEST_F(LibraryTest, libraries_changed) {
  string libName = "foo";
  string libPath;
  create_library(libName, libPath);
}
