package org.inspirenxe.strata.testing

A test kit for applications: open a Screen without an engine or a display, find its components, drive it with simulated input and check what it shows.

try (ScreenTester tester = ScreenTester.open(new ShopScreen(shop))) {
    tester.click(tester.byId("quantity", TextBox.class)).type("3")
          .click(tester.find(Button.class, Matching.text("Buy")));
    assertEquals("29.97", tester.byId("total", Label.class).text().plain());
}

The kit ships in the test fixtures of strata-core; a Gradle build adds it with testImplementation(testFixtures("org.inspirenxe:strata-core:<version>")). Its API uses the types of strata-api and strata-spi only, and it brings core at run time. Tests that compare pixels need a real renderer, such as Strata-Swing's snapshots.
