- EMOCK should also work under \*nix(UNIX, Android, MacOS and iOS), or maybe need minor adaptation.
## Quick view
#### Global function
```cpp
// function to be tested
int target_func(int x);
// how to mock
EMOCK(target_func)
.stubs()
.with(any())
.will(returnValue(1));
// assert return 1
ASSERT_EQ(target_func(0), 1);
```
#### Member functions
```cpp
// member functions to be tested
class Foo
{
public:
void bar1(int);
virtual void bar2(double);
static int bar3();
};
////////////////////////////////////
// mock functions specified to be called
void EMOCK_API mock_bar1(Foo* obj, int) {
// ...
}
void EMOCK_API mock_bar2(Foo* obj, double) {
// ...
}
// how to mock kinds of member functions
EMOCK(&Foo::bar1)
.stubs()
.will(invoke(mock_bar1)); // invoke user denfined mocker instead of return value
EMOCK(&Foo::bar2) // virtual mem_fun isn't special
.stubs()
.will(invoke(mock_bar2));
EMOCK(Foo::bar3) // static mem_fun is like global function
.stubs()
.will(returnValue(1));
```
#### Overloaded member functions
```cpp
// overloaded function to be tested
int foobar(int x) {
return x;
}
double foobar(double x) {
return x;
}
// how to mock overloaded functions
EMOCK((int (*)(int))foobar)
.stubs()
.will(returnValue(1));
EMOCK(static_cast
