Azure DevOps Server 2019 Programmatially copy test case error Exception: 'TF237124: Work Item is not ready to save'"。

Question

我能够用这段代码复制大多数测试用例（试图复制共享步骤成为测试用例本身的一部分），但这个测试用例将无法复制，但我看不到任何错误信息以说明原因--有谁能建议尝试其他方法。请看立即窗口的输出。谢谢John。

                ITestStep targetStep = targetTestCase.CreateTestStep();

                targetStep.Description = sourceStep.Description;
                targetStep.ExpectedResult = sourceStep.ExpectedResult;

                //Copy Attachments

                    string testCaseFolder = _tfsServiceUtilities.CreateDirectory(attachmentRootFolder, "TestCase_" + targetTestCase.Id);

                            newAttachment.Comment = attachment.Comment;
                            targetStep.Attachments.Add(newAttachment);
                        }
                    }
                }
                targetTestCase.Actions.Add(targetStep);
                targetTestCase.Save();
            }

由于这段代码对大多数测试用例都有效，所以这个问题可能来自于特定的测试用例。为了缩小问题的范围，请尝试以下项目。

1. 在另一台客户机上运行这段代码 看看是否能正常工作
2. 尝试使用账户API使用来修改这个特定的测试用例，看看是否可以成功保存。
3. 尝试在保存前验证WorkItem。在保存之前，尝试验证WorkItem。验证() 方法将返回一个无效字段的数组列表。
