// Analogous to GMock's built-in MockFunction, but for base::Callback instead of
|
|
// std::function. It takes the full callback type as a parameter, so that it can
|
|
// support both OnceCallback and RepeatingCallback.
|
|
//
|
|
// Use:
|
|
// using FooCallback = base::Callback<int(std::string)>;
|
|
//
|
|
// TEST(FooTest, RunsCallbackWithBarArgument) {
|
|
// base::MockCallback<FooCallback> callback;
|
|
// EXPECT_CALL(callback, Run("bar")).WillOnce(Return(1));
|
|
// Foo(callback.Get());
|
|
// }
|
|
//
|
|
// Can be used with StrictMock and NiceMock. Caller must ensure that it outlives
|
|
// any base::Callback obtained from it.
