为何Azure Pipelines中发布测试结果的链接返回404？

问题 #

Azure Pipelines流水线已运行，检测到测试结果并显示已完成上传，但点击返回的测试结果链接时出现404错误。这是首次在流水线中使用PublishTestResults任务，根据微软官方文档，该任务应“直接可用”，请问是否需要配置LogStore等相关设置？

排查与解决方案 #

• 修复链接转义字符：日志中的链接包含HTML转义字符&，需替换为&，正确访问链接应为：https://dev.azure.com/tmc-it/tmconsulting-us-com/_TestManagement/Runs?runId=20&_a=runCharts
• 验证账号权限：确认当前登录账号拥有该项目的测试运行查看权限，权限不足会导致404
• 检查任务配置：无需额外配置LogStore，PublishTestResults任务默认处理存储。但需确认testResultsFiles参数是否正确指向测试结果文件（如.trx、.xml格式），路径错误会导致实际未上传有效结果
• 等待同步延迟：测试结果上传后可能存在短暂的系统同步延迟，等待1-2分钟后再尝试访问
• 升级任务版本：当前使用的任务版本为2.171.0，可尝试升级至最新版本，旧版本可能存在链接生成的已知bug
