我有一个类 FileGenerator，我正在为 generateFile() 方法编写一个测试，该方法应该执行以下操作:
I have a class FileGenerator, and I'm writing a test for the generateFile() method that should do the following:
1) 它应该调用 BlockAbstractFactory
2) 它应该从子类方法 getBlocks()
2) it should populate variable blockList from the subclass method getBlocks()
3) 它应该调用一个静态方法 createFile 从一个最终的帮助类 FileHelper 传递一个字符串参数
3) it should call a static method createFile from a final helper class FileHelper passing a String parameter
4) 它应该调用blockList中每个BlockController的run方法
4) it should call the run method of each BlockController in the blockList
到目前为止，我有这个空方法:
So far, I have this empty method:
public class FileGenerator {
// private fields with Getters and Setters
public void generateBlocks() {
}
}
我正在使用 JUnit、Mockito 来模拟对象，并且我已经尝试使用 PowerMockito 来模拟静态类和最终类(Mockito 不这样做).
I am using JUnit, Mockito to mock objects and I've tried using PowerMockito to mock static and final classes (which Mockito doesn't do).
我的问题是:我的第一个测试(从 BlockAbstractFactory 调用方法 getBlockList())正在通过，即使 generateBlocks().我已经在 BlockAbstractFactory 中实现了静态方法(目前返回 null)，以避免 Eclipse 语法错误.
My problem is: my first test (calling method getBlockList() from BlockAbstractFactory) is passing, even though there is no implementation in generateBlocks(). I have implemented the static method in BlockAbstractFactory (returning null, so far), to avoid Eclipse syntax errors.
如何测试静态方法是否在 fileGerator.generateBlocks() 中被调用?
How can I test if the static method is called within fileGerator.generateBlocks()?
到目前为止，这是我的测试课:
Here's my Test Class, so far:
@RunWith(PowerMockRunner.class)
public class testFileGenerator {
FileGenerator fileGenerator = new FileGenerator();
@Test
public void shouldCallGetBlockList() {
fileGenerator.setFileType(FileTypeEnum.SPED_FISCAL);
fileGenerator.generateBlocks();
PowerMockito.mockStatic(BlockAbstractFactory.class);
PowerMockito.verifyStatic();
BlockAbstractFactory.getBlockImpl(fileGenerator.getFileType());
}
}
我没有使用 PowerMock 的经验，但是由于您还没有得到答案，所以我只是在阅读文档以查看是否可以帮助您有点在路上.
I have no experience with PowerMock, but since you didn't get an answer yet I'm just been reading through the documentation to see if I can help you a bit on your way.
我发现您需要准备 PowerMock，以便我知道它需要准备哪些静态方法才能被模拟.像这样:
I found that you need to prepare PowerMock so that I knows which static methods it needs to prepare to be mocked. Like so:
@RunWith(PowerMockRunner.class)
@PrepareForTest(BlockAbstractFactory.class) // <<=== Like that
public class testFileGenerator {
// rest of you class
}
这里您可以找到更多信息.
这有帮助吗?
