测试方法之外的 Mockito 存根

Mockito stubbing outside of the test method(测试方法之外的 Mockito 存根)

问题描述

我在测试方法之外有以下方法

I have the following method outside the test method

private DynamicBuild getSkippedBuild() {
    DynamicBuild build = mock(DynamicBuild.class);
    when(build.isSkipped()).thenReturn(true);
    return build;
}

但是当我调用这个方法时，我得到了以下错误

but when I call this method I get the following error

org.mockito.exceptions.misusing.UnfinishedStubbingException: 
Unfinished stubbing detected here:
-> at LINE BEING CALLED FROM

E.g. thenReturn() may be missing.
Examples of correct stubbing:
    when(mock.isOk()).thenReturn(true);
    when(mock.isOk()).thenThrow(exception);
    doThrow(exception).when(mock).someVoidMethod();
Hints:
 1. missing thenReturn()
 2. you are trying to stub a final method, you naughty developer!

当您在测试方法之外存根时，mockito 似乎不高兴.不支持吗?

Looks like mockito is not happy when you stub outside the test method. Is that not supported ?

我可以通过在 @Test 方法中执行存根来实现此功能，但我想在 @Tests 中重复使用存根.

I can get this to work by doing the stubbing in @Test method but I want to reuse the stubbing across @Tests.

推荐答案

如果 isSkipped() 不是 final 方法，这个问题可能表明你尝试存根一种方法，而另一种方法的存根正在进行中.它不受支持，因为 Mockito 在其存根 API 中依赖于方法调用的顺序(when() 等).

If isSkipped() is not a final method, this problem probably indicates that you try to stub a method while stubbing of another method is in progress. It's not supported because Mockito relies on order of method invocations (when(), etc) in its stubbing API.

我猜你的测试方法中有这样的东西:

I guess you have something like this in your test method:

when(...).thenReturn(getSkippedBuild());

如果是，则需要改写如下:

If so, you need to rewrite it as follows:

DynamicBuild build = getSkippedBuild();
when(...).thenReturn(build);
