我正在尝试在Kotlin中为我的Android应用程序进行UI测试.由于使用ActivityTestRule的新系统,我无法使其工作:它正确编译,并在运行时,我得到:

java.lang.Exception: The @Rule 'mActivityRule' must be public.

以下是我宣称的mActivityRule:

RunWith(javaClass<AndroidJUnit4>())
LargeTest
public class RadisTest {

    Rule
    public val mActivityRule: ActivityTestRule<MainActivity> = …

显然我需要正确的导入语句来解决这个问题.根据文档AndroidJUnit4,这应该是

import android.support.test.runner.AndroidJUnit4;

当我这样做时,Android Studio突出显示runner为红色并抱怨"无法解析符号'跑步者'".

背景

我遵循Android开发者网站上的教程,使用UI Automator设置测试,从而达到了这一点.我遇到的第一个问题是,com.android.support:support-v4:22.2.0并com.android.support.test:runner:0.2依赖于不同的版本com.android.support:support-annotations.我按照Android漏洞报告的建议,allprojects在我的项目中添加了以下内容build.gradle:

configurations.all {
    resolutionStrategy.force 'com.android.support:support-annotations:22.1.0'
}

这解决了即时错误,但我怀疑它导致了我当前的问题.有没有人有任何关于如何解决这个问题的建议？

从`./gradlew:app:dependencies中重新发布部分

compile - Classpath …

我有以下代码:

    @BeforeClass
    public static void setUpOnce() throws InterruptedException {
        fail("LOL");
    }

以及@Before,@ After,@ Test或@AfterClass方法的各种其他方法.

启动时测试不会失败,因为它似乎应该.有谁可以帮助我吗？

我有JUnit 4.5

该方法在立即调用setUp()时失败,该注释被注释为@before.类def是:

public class myTests extends TestCase {

我尝试为 android 运行 Kotlin 仪器测试。

在我的 app/build.gradle 中：

    android {
        dataBinding {
            enabled = true
        }
        compileSdkVersion 28
        defaultConfig {
            applicationId "com.myproject"
            minSdkVersion 18
            targetSdkVersion 28
            versionCode 6
            versionName "0.0.7"
            testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
        }

        sourceSets {
            main.java.srcDirs += 'src/main/kotlin'
            androidTest.java.srcDirs += 'src/androidTest/kotlin'
        }

androidTestImplementation 'androidx.test.espresso:espresso-core:3.2.0-alpha02'
    androidTestImplementation 'androidx.test.ext:junit:1.1.0'
    androidTestImplementation 'androidx.test:rules:1.1.2-alpha02'
    androidTestImplementation 'androidx.test:runner:1.1.2-alpha02'

在文件夹中/app/src/androidTest/kotlin/com/myproject/ 我有 Kotlin 测试：

import androidx.test.ext.junit.runners.AndroidJUnit4
import androidx.test.filters.SmallTest
import org.junit.Rule
import org.junit.runner.RunWith

import androidx.test.rule.ActivityTestRule
import com.myproject.ui.activity.TradersActivity
import org.junit.Before


@RunWith(AndroidJUnit4::class)
@SmallTest
class TradersActivityTest {

    private lateinit var stringToBetyped: String

    @get:Rule …

当我运行 UI 测试时，它们工作得很好，并且我可以看到测试已通过日志传递。但 Android Studio 面板上的测试状态从未更新。

有人遇到过同样的问题吗？

我正在使用espresso运行一些测试,但我不知道为什么roboelectric包含在此错误中,因为测试仅适用于浓缩咖啡,下面是错误:

我按照浓缩咖啡的文档,我看到一切都很好.可能是什么问题呢 :

下面是我的gradle文件:

apply plugin: 'com.android.application'
apply plugin: 'jacoco'

我正在尝试使用 Android Studio 为我的MainActivity.java班级使用 Junit4进行仪器测试 。我不知道我的代码是否正确，但这是我的测试类代码：

import android.widget.EditText;
import android.widget.TextView;

import androidx.test.espresso.Espresso;
import androidx.test.ext.junit.runners.AndroidJUnit4;
import androidx.test.rule.ActivityTestRule;

import static org.junit.Assert.*;

import org.junit.Before;
import org.junit.Rule;
import org.junit.Test;
import org.junit.runner.RunWith;

@RunWith(AndroidJUnit4.class)
public class MainActivityTest{

    private EditText edt;
    private TextView txt;

    @Rule
    ActivityTestRule<MainActivity> activityTestRule = new ActivityTestRule<>(MainActivity.class);

    @Before
    public void setup(){
        edt = activityTestRule.getActivity().findViewById(R.id.edt);
        txt = activityTestRule.getActivity().findViewById(R.id.txt);
    }

    @Test
    public void edt_text_change() {
        //i want this test to be passed
        assertEquals("147", "147");
    }
}
