testing - 我在哪里可以获得现有单元测试的数量

Question

我喜欢获取去年运行的每个构建中的单元测试数量。这样我就可以看看开发人员是否编写了一些新的测试。

为此，我获得了 TFS 仓库数据库的视图，并找到了视图 TestResultView，它正好为我提供了我需要的数据。

查询示例：

SELECT BuildId, YEAR(ResultDate) as year, MONTH(ResultDate) as month , DAY(ResultDate) as day, COUNT(*) AS Passed, 0 AS Failed FROM TestResultView
WHERE BuildDefinitionName = 'Test'
AND TestResultAttributesOutcome = 'Passed'
GROUP BY BuildId, YEAR(ResultDate), MONTH(ResultDate), DAY(ResultDate)
UNION ALL
SELECT BuildId, YEAR(ResultDate) as year, MONTH(ResultDate) as month, DAY(ResultDate) as day, 0 as Passed, COUNT(*) AS Failed FROM TestResultView
WHERE BuildDefinitionName = 'Test'
AND TestResultAttributesOutcome = 'Failed'
GROUP BY BuildId, YEAR(ResultDate), MONTH(ResultDate), DAY(ResultDate)

唯一的问题是我只看到最后四天。

我使用了错误的视图、数据库还是有任何其他方式来获取这些信息？

非常感谢您的帮助。

您可以尝试使用 REST API 来获取现有单元测试的数量（只能获取运行单元测试，如果单元测试从未运行过，那么我们无法获取它们）。

首先获取测试运行列表，然后获取特定测试运行的测试结果。

获取测试运行列表（REST API）：

GET https://server:8080/tfs/DefaultCollection/project/_apis/test/runs?api-version=1.0

获取测试结果列表（REST API）：

GET https://server:8080/tfs/Defaultcollection/project/_apis/test/runs/{runid}/results?api-version=3.0-preview

您可以简单地使用下面的 PowerShell 脚本来获取项目中每个测试运行的单元测试计数，然后可以将列表导出到.csv文件（在 Excel 中打开）以计算特定项目中的单元测试数量。您可以按测试过滤completeDate，或定期运行脚本，然后比较计数和测试名称以识别新添加的测试。
