Struct ViewTestSpecification

Source
pub struct ViewTestSpecification<'a, State, Event>
where State: PartialEq + Debug,
{ /* private fields */ }
Expand description

A test specification DSL for views that supports the `given-then`` format. The DSL is used to specify the events that have already occurred (GIVEN), and the expected view state (THEN) that should be generated based on these events.

fn fg(&self, value: Color) -> Painted<&T>

use yansi::{Paint, Color};

painted.fg(Color::White);

use yansi::Paint;

painted.white();

Enable styling painted only when both stdout and stderr are TTYs:

use yansi::{Paint, Condition};
