Expand description
Inherent data provider that supplies mocked validation data.
This is useful when running a node that is not actually backed by any relay chain. For example when running a local node, or running integration tests.
We mock a relay chain block number as follows: relay_block_number = offset + relay_blocks_per_para_block * current_para_block To simulate a parachain that starts in relay block 1000 and gets a block in every other relay block, use 1000 and 2
Optionally, mock XCM messages can be injected into the runtime. When mocking XCM,
in addition to the messages themselves, you must provide some information about
your parachain’s configuration in order to mock the MQC heads properly.
See MockXcmConfig
for more information
Fields§
§current_para_block: u32
The current block number of the local block chain (the parachain)
relay_offset: u32
The relay block in which this parachain appeared to start. This will be the relay block number in para block #P1
relay_blocks_per_para_block: u32
The number of relay blocks that elapses between each parablock. Probably set this to 1 or 2 to simulate optimistic or realistic relay chain behavior.
para_blocks_per_relay_epoch: u32
Number of parachain blocks per relay chain epoch
Mock epoch is computed by dividing current_para_block
by this value.
relay_randomness_config: R
Function to mock BABE one epoch ago randomness
xcm_config: MockXcmConfig
XCM messages and associated configuration information.
raw_downward_messages: Vec<Vec<u8>>
Inbound downward XCM messages to be injected into the block.
raw_horizontal_messages: Vec<(ParaId, Vec<u8>)>
