我正在尝试编写一个单元测试来检查方法是否按顺序调用。为此,我正在使用 Mockito 的 inOrder.verify() ,如下所示:

@Test
public void shouldExecuteAllFileCommandsOnAFileInFIFOOrder() {
    // Given
    ProcessFileListCommand command = new ProcessFileListCommand();

    FileCommand fileCommand1 = mock(FileCommand.class, "fileCommand1");
    command.addCommand(fileCommand1);

    FileCommand fileCommand2 = mock(FileCommand.class, "fileCommand2");
    command.addCommand(fileCommand2);

    File file = mock(File.class, "file");
    File[] fileArray = new File[] { file };

    // When
    command.executeOn(fileArray);

    // Then
    InOrder inOrder = Mockito.inOrder(fileCommand1, fileCommand2);
    inOrder.verify(fileCommand1).executeOn(file);
    inOrder.verify(fileCommand2).executeOn(file);
}

但是,第二个 verify() 失败并出现以下错误:

org.mockito.exceptions.verification.VerificationInOrderFailure: 
Verification in order failure
Wanted but not invoked:
fileCommand2.executeOn(file);
-> at (...)
Wanted anywhere AFTER following interaction:
fileCommand1.executeOn(file);
-> at (...)

如果我更改.executeOn(file).executeOn(any(File.class))测试通过,但我想确保使用相同的参数调用这些方法。

这是我正在测试的课程:

public class ProcessFileListCommand implements FileListCommand {

    private List<FileCommand> commands = new ArrayList<FileCommand>();

    public void addCommand(final FileCommand command) {
        this.commands.add(command);
    }

    @Override
    public void executeOn(final File[] files) {
        for (File file : files) {
            for (FileCommand command : commands) {
                file = command.executeOn(file);
            }
        }
    }
}

测试失败,因为第二个executeOn()方法调用的参数与第一个方法调用的参数不是同一个文件,因为第一个文件被另一个文件替换

 file = command.executeOn(file);
