Type Definition concordium_std::test_infrastructure::ReceiveContextTest[−][src]

pub type ReceiveContextTest<'a> = ContextTest<'a, ReceiveOnlyDataTest>;

Expand description

Placeholder for the receiving context. All the fields can be set optionally and the getting an unset field will result in calling fail!. Use only in tests!

Setters

Every field have a setter function prefixed with set_.

Example

Creating an empty context and setting the init_origin.

let owner = AccountAddress([0u8; 32]);
let mut ctx = ReceiveContextTest::empty();
ctx.set_owner(owner);
ctx.set_sender(Address::Account(owner));

Set chain meta data

Chain meta data is set using setters on the context or by setters on a mutable reference of ChainMetaTest.

Example

Creating an empty context and setting the slot_time metadata.

let mut ctx = ReceiveContextTest::empty();
ctx.set_metadata_slot_time(1609459200);

or

let mut ctx = ReceiveContextTest::empty();
ctx.metadata_mut().set_slot_time(1609459200);

Use case example

Creating a context for running unit tests

#[receive(contract = "mycontract", name = "receive")]
fn contract_receive<R: HasReceiveContext, L: HasLogger, A: HasActions>(
    ctx: &R,
    amount: Amount,
    logger: &mut L,
    state: &mut State,
) -> ReceiveResult<A> {
    ensure!(ctx.sender().matches_account(&ctx.owner()), "Only the owner can increment.");
    Ok(A::accept())
}

        let mut ctx = ReceiveContextTest::empty();
        ctx.set_owner(owner);
        ctx.set_sender(Address::Account(owner));
        ...
        let result: ReceiveResult<ActionsTree> = contract_receive(&ctx, 0, &mut logger, state);
    }
