Flow and timing

await_until(body: Fn)

Re-run the expression until its assertion holds or the default timeout elapses; returns the body’s value, so .value() can bind a verified value.

Example

await_until(|| assert(a.registered).is_true());

await_until(body: Fn, within: string)

Like await_until(body) but with an explicit timeout, e.g. "15s".

Example

await_until(|| assert(b.state).equals(State::Ringing), "15s");

default_timeout(duration: string)

Set the default await_until timeout for the rest of the script (e.g. "10s").

parallel(tasks: array)

Returns array

Run the given zero-arg closures concurrently and wait for all; returns their results as an array, and fails if any task fails. Use it for independent blocking work, e.g. verify_audio on several agents at once. Tasks may share captured variables (each gets an independent snapshot, so they can’t race). Don’t overlap await_until across tasks; its silencing is global.

Example

let results = parallel([
    || http("GET", env("A_URL")),
    || http("GET", env("B_URL")),
]);

wait(seconds: int)

Hold for N seconds; FAILS if a call that is established at the start drops.

Example

wait(3); // the call must stay up for 3s
