如何使用Python REST API从VSTS（Azure DevOps）中的查询中提取工作项？

Question

我正在使用Azure DevOps的官方Python REST
API：https :
//github.com/Microsoft/azure-devops-python-
api

多亏了这些示例，我才能够从id检索有关测试用例的信息。

如何通过查询（WIQL）做到这一点？

到目前为止，这是我的代码（带有经过修改的标记和链接）：

from vsts.vss_connection import VssConnection
from msrest.authentication import BasicAuthentication


token = "hcykwckuhe6vbnigsjs7r3ai2jefsdlkfjslkfj5mxizbtfu6k53j4ia"
team_instance = "https://tfstest.toto.com:8443/tfs/Development/"

credentials = BasicAuthentication("", token)
connection = VssConnection(base_url=team_instance, creds=credentials)


def print_work_items(work_items):
    for work_item in work_items:
        print(
            "{0} {1}: {2}".format(
                work_item.fields["System.WorkItemType"],
                work_item.id,
                work_item.fields["System.Title"],
            )
        )


WIT_CLIENT = (
    "vsts.work_item_tracking.v4_1.work_item_tracking_client.WorkItemTrackingClient"
)
wit_client = connection.get_client(WIT_CLIENT)


def get_TC_by_id(desired_ids):
    work_items = wit_client.get_work_items(ids=desired_ids, error_policy="omit")
    print_work_items(work_items)


def get_TC_from_query(query):
    # THIS FUNCTION IS NOT WORKING...
    work_items = wit_client.get_work_items(query=query, error_policy="omit")
    print_work_items(work_items)


get_TC_by_id([1035375])

get_TC_from_query(
    """\
SELECT
        [System.Id],
        [System.WorkItemType],
        [System.Title],
        [System.State],
        [System.AreaPath],
        [System.IterationPath]
FROM workitems
WHERE
        [System.TeamProject] = @project
        AND [System.WorkItemType] = 'Test Case'
ORDER BY [System.ChangedDate] DESC
"""
)

这是我得到的错误

  File "test_TFS.py", line 35, in get_TC_from_query
    work_items = wit_client.get_work_items(query=query, error_policy="omit")
TypeError: get_work_items() got an unexpected keyword argument 'query'

如何从查询中检索测试用例？

特别是，我不了解“客户”的价值，例如
"vsts.work_item_tracking.v4_1.work_item_tracking_client.WorkItemTrackingClient"

谢谢你们！

Answer 1

在VSTS示例的Github存储库中发布了一条消息（即导致请求请求的问题）之后，我得到了解决问题的提示。

解决方案是使用：

• 一个带有Wiql类的wiql查询对象
• query_by_wiql 功能
• 将查询结果（具有WorkItem ID的引用）转换为具有get_work_item功能的WorkItem （或get_work_items通过一次处理处理多个WorkItem）

这是我对这个问题的解决方案：

[针对版本5.1和azure-devops模块进行了更新，以取代VSTS]

from azure.devops.connection import Connection
from msrest.authentication import BasicAuthentication
from azure.devops.v5_1.work_item_tracking.models import Wiql


token = "hcykwckuhe6vbnigsjs7r3ai2jefsdlkfjslkfj5mxizbtfu6k53j4ia"
team_instance = "https://tfstest.toto.com:8443/tfs/Development/"

credentials = BasicAuthentication("", token)
connection = Connection(base_url=team_instance, creds=credentials)


def print_work_items(work_items):
    for work_item in work_items:
        print(
            "{0} {1}: {2}".format(
                work_item.fields["System.WorkItemType"],
                work_item.id,
                work_item.fields["System.Title"],
            )
        )


wit_client = connection.clients.get_work_item_tracking_client()


def get_TC_from_query(query):
    query_wiql = Wiql(query=query)
    results = wit_client.query_by_wiql(query_wiql).work_items
    # WIQL query gives a WorkItemReference => we get the corresponding WorkItem from id
    work_items = (wit_client.get_work_item(int(result.id)) for result in results)
    print_work_items(work_items)
