我正在 android studio 中编写单元测试并使用 PowerMock
测试看起来像这样
@RunWith(PowerMockRunner.class)
@PrepareOnlyThisForTest({Typeface.class})
public class ExtendedTextViewTest {
...
@Test
public void ctor_context_attributeSet_ShouldSetTypeface() throws Exception {
// Act
final LinkedList<Typeface> actualTypefaces = new LinkedList<Typeface>();
ExtendedTextView textView = spy(new ExtendedTextView(contextMock, attributeSet) {
@Override
public void setTypeface(Typeface typeface) {
actualTypefaces.add(typeface);
}
});
// Assert
MoreAsserts.assertEquals(new Typeface[]{typefaceMock}, actualTypefaces.toArray());
verify(typedArrayMock, times(1)).recycle();
}
}
当我运行测试时出现错误:
java.lang.RuntimeException: Method assertEquals in android.test.MoreAsserts not mocked. See http://g.co/androidstudio/not-mocked for details.
at android.test.MoreAsserts.assertEquals(MoreAsserts.java)

似乎 mockito 在没有我要求的情况下 mock 了 MoreAsserts ...我错过了什么？
谢谢， 光荣
最佳答案
好的，搜索后我找到了答案...... MoreAsserts是一个android sdk类(android.test.MoreAsserts)
当运行单元测试时，android sdk 没有加载，而是所有的类都被一个抛出异常的实现 stub ，包括 MoreAsserts..
所以我需要用 JUNit 断言替换断言:Assert.assertArrayEquals
Assert.assertArrayEquals(new Typeface[]{typefaceMock}, actualTypefaces.toArray());
希望对大家有所帮助=]
关于android - PowerMock 模拟 MoreAsserts，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/35800075/
