Rally 如何通过自动化在现有测试运行中添加测试用例

我已经在测试集上创建了测试用例，我想在现有的测试运行中添加测试用例。我使用更新请求来添加测试用例，但它会在测试运行中删除现有的测试用例并添加它

if(!testCaseList.isJsonNull()&&!update){
            restApi.setApplicationName("PSN")
            JsonObject newTS = new JsonObject()
            newTS.addProperty("Name", TSName)
            newTS.addProperty("PlanEstimate", points)
            newTS.addProperty("Project", projectRef)
            newTS.addProperty("Owner", userRef)
            if (releaseRef!="") newTS.addProperty("Release", releaseRef)
            if (iterationRef!="") newTS.addProperty("Iteration", iterationRef)
            newTS.add("TestCases", testCaseList)
            CreateRequest createRequest = new CreateRequest("testset",newTS)
            CreateResponse createResponse = restApi.create(createRequest)
            ref = createResponse.getObject().get("_ref").getAsString()
        }
        else if(!testCaseList.isJsonNull()&&update){
            restApi.setApplicationName("PSN")
            newTS.addProperty("Name", TSName)
            newTS.addProperty("PlanEstimate", points)
            newTS.addProperty("Project", projectRef)
            newTS.addProperty("Owner", userRef)
            if (releaseRef!="") newTS.addProperty("Release", releaseRef)
            if (iterationRef!="") newTS.addProperty("Iteration", iterationRef)
            newTS.add("TestCases", testCaseList)
            UpdateRequest updateRequest = new UpdateRequest(ref,newTS)
            UpdateResponse updateResponse = restApi.update(updateRequest)
            ref = updateResponse.getObject().get("_ref").getAsString()

        }

您希望使用CollectionUpdateRequest和updateCollection方法，而不是直接设置TestCases集合

CollectionUpdateRequest testsetTestCasesAddRequest = new CollectionUpdateRequest(ref + "/testcases", testCaseList, true);
CollectionUpdateResponse testsetTestCasesAddResponse = restApi.updateCollection(testsetTestCasesAddRequest);
