Contains helpers for testing the Google Cloud C++ Client Libraries.
The symbols defined in this namespace are part of google-cloud-cpp
's public API. Application developers may use them when mocking the client libraries in their own tests.
Retrieve options used in a client call.
This would be used to verify configuration options from within a MockConnection. It provides a way for applications to test the difference between client.Foo(request, options)
and client.Foo(request)
.
TEST(Foo, CallOptions) {
auto mock = std::make_shared<MockConnection>();
EXPECT_CALL(*mock, Foo).WillOnce([] {
auto const& options = google::cloud::mocks::CurrentOptions();
EXPECT_THAT(options, ...);
});
auto client = Client(mock);
MyFunctionThatCallsFoo(client);
}
Returns Type Description Options const &
MakeStreamRange(std::vector< T >, Status)
Construct a StreamRange
<T>
for use in tests.
auto sr = MakeStreamRange<T>({t1, t2});
for (StatusOr<T> const& t : sr) {
// Yields t1 -> t2
}
sr = MakeStreamRange<T>({t1, t2}, BadStatus());
for (StatusOr<T> const& t : sr) {
// Yields t1 -> t2 -> BadStatus()
}
Parameters Name Description values
The successfully returned T
values.
final_status
The final Status of the range. Defaults to an OK Status.
typename T
StreamRange< T >
