Expand description

Internal state of the externalities.

This can be used in tests to respond or assert stuff about interactions.

Fields

requests: BTreeMap<HttpRequestId, PendingRequest>

A list of pending requests.

persistent_storage: TestPersistentOffchainDB

Persistent local storage

local_storage: InMemOffchainStorage

Local storage

seed: [u8; 32]

A supposedly random seed.

timestamp: Timestamp

A timestamp simulating the current time.

Implementations

impl OffchainState

pub fn fulfill_pending_request(
    &mut self,
    id: u16,
    expected: PendingRequest,
    response: impl Into<Vec<u8, Global>>,
    response_headers: impl IntoIterator<Item = (String, String )>
)

Asserts that pending request has been submitted and fills it’s response.

pub fn expect_request(&mut self, expected: PendingRequest)

Add expected HTTP request.

This method can be used to initialize expected HTTP requests and their responses before running the actual code that utilizes them (for instance before calling into runtime). Expected request has to be fulfilled before this struct is dropped, the response and response_headers fields will be used to return results to the callers. Requests are expected to be performed in the insertion order.
