pub fn schedule_raw_operation(&self, operation: Vec<u8>)

Schedules an operation to be included in the block being built.

The operation is specified as an opaque blob of bytes.

pub fn schedule_operation(&self, operation: &impl Serialize)

Schedules an operation to be included in the block being built.

The operation is serialized using BCS.

pub fn raw_scheduled_operations(&self) -> Vec<Vec<u8>>

Returns the list of operations scheduled since the most recent of:

• the last call to this method;
• the last call to Self::scheduled_operations;
• or since the mock runtime was created.

pub fn scheduled_operations<Operation>(&self) -> Vec<Operation>

where Operation: DeserializeOwned,

Returns the list of operations scheduled since the most recent of:

• the last call to this method;
• the last call to Self::raw_scheduled_operations;
• or since the mock runtime was created.

All operations are deserialized using BCS into the Operation generic type.

pub fn with_query_application_handler( self, handler: impl FnMut(ApplicationId, Vec<u8>) -> Vec<u8> + Send + 'static, ) -> Self

Configures the handler for application queries made during the test.

pub fn add_expected_http_request( &mut self, request: Request, response: Response, )

Adds an expected http_request call, and the response it should return in the test.

pub fn http_request(&self, request: Request) -> Response

Makes an HTTP request as an oracle and returns the HTTP response.

Should only be used with queries where it is very likely that all validators will receive the same response, otherwise most block proposals will fail.

Cannot be used in fast blocks: A block using this call should be proposed by a regular owner, not a super owner.
