Set raise error condition

to_raise(.data, ...)



input. Anything that can be coerced to a StubbedRequest class object


One or more HTTP exceptions from the fauxpas package. Run grep("HTTP*", getNamespaceExports("fauxpas"), value = TRUE) for a list of possible exceptions


an object of class StubbedRequest, with print method describing the stub


The behavior in the future will be:

When multiple exceptions are passed, the first is used on the first mock, the second on the second mock, and so on. Subsequent mocks use the last exception

But for now, only the first exception is used until we get that fixed


see examples in stub_request()

Raise vs. Return

to_raise() always raises a stop condition, while to_return(status=xyz) only sets the status code on the returned HTTP response object. So if you want to raise a stop condition then to_raise() is what you want. But if you don't want to raise a stop condition use to_return(). Use cases for each vary. For example, in a unit test you may have a test expecting a 503 error; in this case to_raise() makes sense. In another case, if a unit test expects to test some aspect of an HTTP response object that httr or crul typically returns, then you'll want to_return().
