geb自动化中未调用env.groovy的Before（）方法

我正在运行黄瓜测试，但我得到了一个错误

我创建了env.groovy，如下所示：

import cucumber.api.Scenario
import cucumber.runtime.ScenarioImpl
import geb.Browser
import geb.binding.BindingUpdater
import io.appium.java_client.InteractsWithApps
import org.openqa.selenium.logging.LogEntries
import org.openqa.selenium.remote.RemoteLogs

import static cucumber.api.groovy.Hooks.*

BindingUpdater bindingUpdater
Browser theBrowser = null


Before(100) { Scenario scenario ->

(theBrowser?.driver as InteractsWithApps)?.resetApp()
sleep(5000) //give time for app to fully reset before starting test

theBrowser = new Browser()
bindingUpdater = new BindingUpdater(binding, theBrowser)
bindingUpdater.initialize()
TestFramework.init(theBrowser)
println("***In Init()")
}

After(100) { Scenario scenario ->
bindingUpdater?.remove()

// embed screenshot into cucumber report
if(theBrowser && scenario.failed) {

    RemoteLogs logs = theBrowser.driver.manage().logs()

    LogEntries logcat
    if (false && "logcat" in logs.availableLogTypes) {
        ByteArrayOutputStream bos = new ByteArrayOutputStream()
        ObjectOutputStream oos = new ObjectOutputStream(bos)
        logs.get("logcat")?.each {
            oos.writeObject(it.toString() + '\n');
        }
        scenario.embed(bos.toByteArray(), "text/plain")
    }

    String failedStep = (scenario as ScenarioImpl).stepResults.findIndexOf { it.error }
    String reportLabel = "${scenario.name}-step-${failedStep}-${scenario.status}"
    theBrowser.report(reportLabel)
}
}

我的TestFramework.groovy包含：

public class TestFramework {

/**
 * The application under test.
 */
private static MyApplication mApp;

/**
 * Initialize the test framework.
 *
 * @param browser The application browser.
 */
public static void init(Browser browser) {
    mApp = new MyApplication(browser)
}

/**
 * Gets the application.
 *
 * @return The application.
 */
public static MyApplication getApp() {
    assert mApp != null
    return mApp;
  }
}

我在步骤文件中使用了getApp（）方法：

MyApplication mApp
String testNote

Before { Scenario scenario ->
mApp = TestFramework.getApp()
}

Given(~/^app is in session$/){ ->
// nothing is in given
}

When(~/^the (.*?) is clicked$/){String team ->
mApp.home.selectTeam(getTeam(team))
}

---

我想知道为什么会出现NullPointerException？

确保您的env.groovy文件存在于steps包中，并确保有测试运行程序

@RunWith(Cucumber)
@CucumberOptions(
        plugin = ['pretty'],
        features=["src/test/groovy/cucumber/features"],
        glue=["src/test/groovy/cucumber/steps"],
        tags="@manual"


)
