Struct unsegen::base::terminal::test::FakeTerminal

pub struct FakeTerminal { /* fields omitted */ }

A fake terminal that can be used in tests to create windows and compare the resulting contents to the expected contents of windows.

Implementations

impl FakeTerminal

pub fn with_size((w, h): (u32, u32)) -> Self

Create a window with the specified (width, height).

pub fn from_str(
    (w, h): (u32, u32),
    description: &str
) -> Result<Self, ShapeError>

Create a fake terminal from a format string that looks roughly like this:

"1 1 2 2 3 3 4 4"

Spaces and newlines are ignored and the string is coerced into the specified size.

pub fn assert_looks_like(&self, string_description: &str)

Test if the terminal contents look like the given format string. The rows are separated by a "|".

Examples:

use unsegen::base::terminal::test::FakeTerminal;
use unsegen::base::GraphemeCluster;

let mut term = FakeTerminal::with_size((2,3));
{
    let mut win = term.create_root_window();
    win.fill(GraphemeCluster::try_from('_').unwrap());
}

term.assert_looks_like("__|__|__");

pub fn create_root_window(&mut self) -> Window<'_>

Create a root window that covers the whole terminal grid.
