Macro count_category 

macro_rules! count_category {
    ($actions:expr, $category:expr) => { ... };
}

Count how many actions belong to a specific category.

This requires the action type to implement ActionCategory.

Example

use tui_dispatch::testing::count_category;

let actions = harness.drain_emitted();
assert_eq!(count_category!(actions, "search"), 3);
