java - 将 TestFX 与 Cucumber 结合使用

Question

我尝试将 Cucumber 与 TestFX 结合使用，但无法从应用程序获取任何节点。

我有另一类 TestFX 可以正常工作，另一类 Cucumber 也可以正常工作。但我越来越

org.loadui.testfx.exceptions.NoNodesFoundException: No nodes matched 'TextInputControl has text "Can you find this label"'.

TestFXBase:

import javafx.scene.Node;
import javafx.scene.input.KeyCode;
import javafx.scene.input.MouseButton;
import javafx.stage.Stage;

import org.junit.After;
import org.junit.Before;
import org.junit.BeforeClass;
import org.testfx.api.FxToolkit;
import org.testfx.framework.junit.ApplicationTest;

import java.util.concurrent.TimeoutException;


public class TestFXBase extends ApplicationTest {

    private static boolean isHeadless = false;

    @BeforeClass
    public static void setupHeadlessMode() {
       if(isHeadless){
            System.setProperty("testfx.robot", "glass");
            System.setProperty("testfx.headless", "true");
            System.setProperty("prism.order", "sw");
            System.setProperty("prism.text", "t2k");
            System.setProperty("java.awt.headless", "true");
        }


    }

    @Before
    public void setUpClass() throws Exception {
        ApplicationTest.launch(Main.class);
    }

    @Override
    public void start(Stage stage) throws Exception {
        stage.show();
    }

    @After
    public void afterEachTest() throws TimeoutException {

        FxToolkit.hideStage();
        release(new KeyCode[]{});
        release(new MouseButton[]{});
    }

    /* Helper method to retrieve Java FX GUI Components */
    public <T extends Node> T find (final  String query){
        return (T) lookup(query).queryAll().iterator().next();
    }

}

这是我的 testfx 基类，我的 Cucumber runner 和 stepdefs 扩展了它。

StepDef:

import cucumber.api.java.en.Given;
import cucumber.api.java.en.Then;
import org.junit.Test;


public class MyStepdefs extends TestFXBase  {
    @Test
    @Given("^That \"([^\"]*)\" Exists$")
    public void thatExists(String arg0) throws Throwable {
        rightClickOn("#rect");
    }
    @Test
    @Then("^Which is \"([^\"]*)\"$")
    public void whichIs(String arg0) throws Throwable {
        System.out.println(arg0);
    }
}

运行者:

import cucumber.api.CucumberOptions;
import cucumber.api.junit.Cucumber;
import org.junit.runner.RunWith;


@RunWith(Cucumber.class)
@CucumberOptions(plugin = { "pretty" })
public class MyRunner extends TestFXBase{}

功能:

Feature: Do label texts exist?

Scenario: Can you find this label text

Given That "Can you find this label" Exists

Then Which is "great"

因此，参数已传递，但 TestFX 不会在我的 cucumber 运行器中启动应用程序，只是尝试查找节点。有一个类可以扩展 TestFXBase 并且可以完美运行。我该如何解决这个问题？

Answer 1

这里的解决方案是将 setupHeadlessMode 和 setUpClass 方法的内容移动到 TestFXBase 类初始值设定项:

static {
    if (isHeadless) {
        System.setProperty("testfx.robot", "glass");
        System.setProperty("testfx.headless", "true");
        System.setProperty("prism.order", "sw");
        System.setProperty("prism.text", "t2k");
        System.setProperty("java.awt.headless", "true");
    }

    try {
        ApplicationTest.launch(Main.class);
    } catch (Exception e) {
        // oh no
    }
}
