I was making a quick mocking infrastructure for internal mocks so
I wouldn't have to pass in objects to constructors all the time
and came up with this:
[code]
mixin template internalMockRig(alias _var, string _varName, alias
_varStandard, alias _varMock) {
version(unittest) {
@property bool internalMockSetting() {
return _useInternalMocks;
}
@property useInternalMocks(bool uim) {
// Are we changing the mock type?
if (uim != _useInternalMocks) {
_useInternalMocks = uim;
if(_useInternalMocks) {
_var = new _varMock;
}
else {
_var = new _varStandard;
}
}
}
private: bool _useInternalMocks = false;
}
}
[/code]
Then in the object:
[code]
class usingTestThing {
testThing thing;
mixin internalMockRig!(thing, testThing, testThingMock);
this() {
thing = new testThing;
}
}
[/code]
This works great as long as there is only one mock object. I
thought about using string mixins to generate the properties on a
per-variable basis, but the problem is that I can't figure out
how to get the string of the variable name from the aliased
template mixin parameter. Is there a way to do this?
If not, I'll have to pass in the strings of the variables
seperately (as in: mixin internalMockRig!(thing, "thing",
testThing, "testThing", testThingMock, "testThingMock"); ), but
that seems inelegant (and a bit error prone).
