单元测试 ArrayMap throws Method put in android.util.ArrayMap not mocked

问题描述

我正在尝试对使用数组映射的方法进行单元测试，但我不断收到以下异常:

I am trying to unit test a method that uses array map and I keep getting the following exception:

java.lang.RuntimeException: Method put in android.util.ArrayMap not mocked. See http://g.co/androidstudio/not-mocked for details.

代码:

  ArrayMap<String, String> sampleMap =new ArrayMap<>();
                            for (SampleInfo info : details.getSampleList())
                            {
                                sampleMap.put(info.getkey(),info.getName());
                            }

我试过了:

testOptions {
        unitTests.returnDefaultValues = true
    }

这样可以避免异常，但地图始终为空.如何解决这个问题?

This way the exception is avoided but the map is always empty. How to resolve this issue?

推荐答案

为我工作，确保它在 build.gradle 的正确部分

Worked for me, make sure its in the correct part of the build.gradle

android {

  ...

  testOptions { 
     unitTests.returnDefaultValues = true
  }
}
