我正在测试的功能，

class FileUtility {
    companion object {
        @JvmStatic
        fun deleteFile(filePath: String) {
            try {
                val file = getFileObject(filePath)
                file.delete()
            } catch (ex :Exception) {
                log.error("Exception while deleting the file", ex)
            }
        }
    }
}

字符串
单元测试，

@Test
fun deleteFileTest() {
    val filePath = "filePath"
    val file = mockk<File>()
    every { getFileObject(filePath) } returns file
    deleteFile(filePath)
    verify { file.delete() }
}

运行此测试用例时出现以下错误

io.mockk.MockKException: Missing calls inside every { ... } block.

型
这是一个bug还是我写错了测试用例？
