fn assert_snapshot

Compares {value} with the snapshot of this test in snapshots/ (§18.2, D-7080); oxl test --update-snapshots rewrites it. Borrows the value (D-7421: the interpolation of a borrowed generic &T no longer drops it, D-7420).

Example:

test "report layout" {
  assert_snapshot(&"total: 3 items")
}

pub(api) fn assert_snapshot<T: Show>(value: &T)

Since. 1.0.0-beta

Parameters

Errors

panics when the text differs from the stored snapshot (the first run creates it).

Effects

none declared (pure unless the body says otherwise)
