我发现在一个干净的Gradle和Maven缓存上运行带有并行模式的Robolectric测试会遇到麻烦。
这是build.gradle：
apply plugin: 'com.android.application'
android {
compileSdkVersion 21
buildToolsVersion "21.1.2"
defaultConfig {
applicationId "com.robolectrictest.robotest"
minSdkVersion 21
targetSdkVersion 21
versionCode 1
versionName "1.0"
}
testOptions.unitTests.all {
testLogging {
events "failed", "skipped"
showStackTraces = true
exceptionFormat = "full"
}
maxParallelForks = 8
forkEvery = 20
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
testCompile 'junit:junit:4.12'
testCompile 'org.robolectric:robolectric:3.0'
androidTestCompile 'junit:junit:4.12'
}
在API 23上构建显示相同的问题。 如果我清除缓存（通过删除〜/ .gradle / caches /和〜/ .m2 / repository）并运行
./gradlew clean test
我遇到以下异常：

现在，文件在那里，格式正确，没有任何奇怪的特殊字符。看起来就像在阅读过程中中断过程一样。
更多细节：这是正在测试的活动
package com.robolectrictest.robotest;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
public class MainActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
final View button = findViewById(R.id.login);
button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
startActivity(new Intent(MainActivity.this, MainActivity.class));
}
});
}
}
布局：
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<Button
android:id="@+id/login"
android:text="Login"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
</LinearLayout>
这是测试，每个类重复10次，有200个类来触发多线程：
public class ExampleUnitTest1 {@Test
public void addition_isCorrect1_1() throws Exception {
MainActivity activity = Robolectric.setupActivity(MainActivity.class);
activity.findViewById(R.id.login).performClick();
Intent expectedIntent = new Intent(activity, MainActivity.class);
Assert.assertNotSame(Shadows.shadowOf(activity).getNextStartedActivity(), expectedIntent);
}
}
我无法在任何地方找到任何相关的错误或问题。有什么想法吗？
