使用AndroidStudio运行JUnit测试的异常:java.lang.NoClassDefFoundError:android/os/Parcelable

Question

我根据http://tools.android.com/tech-docs/unit-testing-support创建了单元测试,但是当我运行它们时,我得到一个异常:

这是我的一个测试的片段:

package com.aadhk.woinvoice.bean;

import com.aadhk.woinvoice.util.Constant;

import junit.framework.TestCase;

import java.util.ArrayList;
import java.util.List;

public class InvoiceCalculatorTest extends TestCase {
  private static final double EPSILON = 1e-4;

  public void testNoTaxNoDiscount() {
    Invoice invoice = new Invoice();
    List<InvoiceItem> items = new ArrayList<>();
    InvoiceItem item = new InvoiceItem();

我正在使用Android Studio 1.1,Android插件版本1.1.3和Gradle版本2.2.1.

我的代码确实实现了Parceable接口,但我希望有一种方法可以运行这些测试.测试本身不以任何方式锻炼或使用Parceable.

刚刚使用 IntelliJ 遇到了这个问题，但我想这也适用于 Android Studio。

我通过为我的测试编辑运行/调试配置并检查“使用替代 JRE”并尝试不同的 Android 平台解决了这个问题。我建议尝试不同的方法，看看它是否能解决问题。
