egui development is sponsored by Rerun, a startup building an SDK for visualizing streams of multimodal data.

egui_kittest

This release welcomes a new crate to the family: egui_kittest. egui_kittest is a testing framework for egui, allowing you to test both automation (simulated clicks and other events), and also do screenshot testing (useful for regression tests). egui_kittest is built using kittest, which is a general GUI testing framework that aims to work with any Rust GUI (not just egui!). kittest uses the accessibility library AccessKit for automatation and to query the widget tree.

kittest and egui_kittest are written by @​lucasmerlin.

Here's a quick example of how to use egui_kittest to test a checkbox:

use egui::accesskit::Toggled;
use egui_kittest::{Harness, kittest::Queryable};
fn main() {
let mut checked = false;
let app = |ui: &mut egui::Ui| {
ui.checkbox(&mut checked, "Check me!");
};
let mut harness = egui_kittest::Harness::new_ui(app);
let checkbox = harness.get_by_label("Check me!");
assert_eq!(checkbox.toggled(), Some(Toggled::False));
checkbox.click();
harness.run();
let checkbox = harness.get_by_label("Check me!");
assert_eq!(checkbox.toggled(), Some(Toggled::True));
// You can even render the ui and do image snapshot tests
#[cfg(all(feature = "wgpu", feature = "snapshot"))]
harness.wgpu_snapshot("readme_example");

}
