Macro render_test 

macro_rules! render_test {
    ($test_name:ident, $widget:expr, $area:expr) => { ... };
}

Test that rendering to a buffer doesn’t panic.

This macro creates a test that ensures a widget can be rendered without panicking, which is useful for visual regression testing.

Examples

use ratatui::buffer::Buffer;
use ratatui::layout::Rect;

render_test!(
    test_piechart_renders,
    PieChart::default(),
    Rect::new(0, 0, 40, 20)
);
