rest - 无法使用对指定测试集的引用来创建/更新 Rally TestCaseResult

Question

有了拉力赛，我需要

Update a TestCaseResult with a new TestSet Ref.

OR

Create a new TestCaseResult by copying everything from a previous TestCaseResult and just changing the TestSet Ref.

我正在尝试通过 Java REST toolkit from Rally 做同样的事情.它似乎在内部使用 JSON REST API。

当我尝试使用 CreateRequest 或 UpdateRequest 执行此操作时，我收到来自 API 的错误消息“无法为测试集设置值:null”

是否无法更新 TestCaseResult 的 TestSet(无论是现有的还是新创建的)？

这是我正在使用的一些示例代码(显示通过更改测试集从现有的创建测试用例结果)。

        //get testcaseresult object
        GetRequest tcrReq = new GetRequest("/testcaseresult/12345.js"); 
        tcrReq.setFetch(new Fetch("FormattedID", "Name"));
        GetResponse tcrResponse = restApi.get(tcrReq);

        //update testcaseresult object with new testset
        JsonObject tsRef = new JsonObject();
        tsRef.addProperty("_ref", "https://rally1.rallydev.com/slm/webservice/1.39/testset/1029348.js");
        tcrResponse.getObject().add("TestSet",tsRef);
        tcrResponse.getObject().remove("_ref");

        //Create API for new testcaseresult object
        CreateRequest createRequest = new CreateRequest("testcaseresult", tcrResponse.getObject());
        CreateResponse createResponse = restApi.create(createRequest);
        if(createResponse.wasSuccessful()){
            System.out.println(createResponse.getObject());
        }else{
            String[] ss = createResponse.getErrors();
            for(int i=0; i<ss.length; i++){
                System.out.println(ss[i]);
            }
        }

能否请您帮助了解我是做错了什么还是拉力赛的限制？

我相信您收到“Could not set value for Test Set: null” 错误消息的原因是 TestCaseResults 上存在一个“不可见”约束，它们所在的 TestCase在可以将 TestCaseResult 作为属性分配给该 TestSet 之前，关联必须被安排到感兴趣的 TestSet 中。

不幸的是，TestCases 上没有 TestSet 属性，因此您必须从 TestSet 中查询 TestCases 集合，然后遍历该集合以检查父 TestCase 是否是该集合的成员。一旦确认 TestCase 位于该 TestSet 的 TestCases 集合中，您就可以继续使用感兴趣的 TestSet 属性成功更新成员 TestCaseResult。我测试了下面的内容，它按预期工作。

下面的代码片段说明了如何实现这一点:

    // Create and configure a new instance of RallyRestApi
    // Connection parameters
    String rallyURL = "https://rally1.rallydev.com";
    String wsapiVersion = "1.38";
    String applicationName = "RestExample_UpdateTestSetOnTestCaseResult";

    // Credentials
    String userName = "user@company.com";
    String userPassword = "password";

    RallyRestApi restApi = new RallyRestApi(
            new URI(rallyURL),
            userName,
            userPassword);
    restApi.setWsapiVersion(wsapiVersion);
    restApi.setApplicationName(applicationName);

    // Ref to Test Case Result of Interest
    String testCaseResultRef = "/testcaseresult/1234567891.js";

    GetRequest testCaseResultRequest = new GetRequest(testCaseResultRef);
    GetResponse testCaseResultResponse = restApi.get(testCaseResultRequest);
    JsonObject testCaseResultObj = testCaseResultResponse.getObject();

    // Get the Test Case Result's Parent Test Case        
    JsonObject testCase = testCaseResultObj.get("TestCase").getAsJsonObject();

    String testCaseRef = testCase.get("_ref").getAsString();
    GetRequest testCaseRequest = new GetRequest(testCaseRef);
    GetResponse testCaseResponse = restApi.get(testCaseRequest);
    JsonObject testCaseObj = testCaseResponse.getObject();

    System.out.println(testCaseRef);

    // Ref to Test Set of Interest
    String testSetRef = "/TestSet/12345678910.js";

    // Get the Test Set of interest
    GetRequest testSetRequest = new GetRequest(testSetRef);
    GetResponse testSetResponse = restApi.get(testSetRequest);
    JsonObject testSetObject = testSetResponse.getObject();

    // Grab the Test Cases in this Test Set
    JsonArray testCasesInTestSet = testSetObject.get("TestCases").getAsJsonArray();

    // Loop through and see if our Test Case of interest is a member
    boolean testCaseIsInSet = false;
    for (int i=0; i<testCasesInTestSet.size(); i++) {
        JsonObject thisTestCase = testCasesInTestSet.get(i).getAsJsonObject();
        String thisTestCaseRef = thisTestCase.get("_ref").getAsString();

        if (thisTestCaseRef.equals(testCaseRef)) {
            testCaseIsInSet = true;
        }
    }

    if (testCaseIsInSet) {
        // Update Test Set on Existing Test Case Result
        try {            

            //Add Test Set
            System.out.println("\nUpdating Existing Test Case Result's Test Set attribute...");
            testCaseResultObj.addProperty("TestSet", testSetRef);

            UpdateRequest updateExistTestCaseResultRequest = new UpdateRequest(testCaseResultRef, testCaseResultObj);
            UpdateResponse updateExistTestCaseResultResponse = restApi.update(updateExistTestCaseResultRequest);

            if (updateExistTestCaseResultResponse.wasSuccessful()) {
                System.out.println("Updated Test Case Result with new Test Set");
                String[] updateExistTestCaseResultWarnings;

                updateExistTestCaseResultWarnings = updateExistTestCaseResultResponse.getWarnings();
                    System.out.println("Warning(s) occurred updating Test Case Result: ");
                for (int i=0; i<updateExistTestCaseResultWarnings.length;i++) {
                    System.out.println(updateExistTestCaseResultWarnings[i]);
                }

            } else {
                String[] updateExistTestCaseResultErrors;
                updateExistTestCaseResultErrors = updateExistTestCaseResultResponse.getErrors();
                    System.out.println("Error occurred updating Test Case Result: ");
                for (int i=0; i<updateExistTestCaseResultErrors.length;i++) {
                    System.out.println(updateExistTestCaseResultErrors[i]);
                }                   
            }
        } catch (Exception e) {
            System.out.println("Exception occurred while updating Tags on existing Test Case: ");
            e.printStackTrace();            
        }

        finally {
            //Release all resources
            restApi.close();
        }
    } else {
        System.out.println("Unable to Update Test Case Result with specified Test Set");
        System.out.println("Parent Test Case is not a member of this Test Set");
    }
