代码覆盖率选项卡未显示TFS 2015构建

Question

我正在使用tfs 2015构建一些代码，运行一些业力测试，并使用karma.config使用业力覆盖报告程序生成Cobetura摘要文件：

coverageReporter: {
        dir: 'testResults/stubs',
        includeAllSources: true,
        reporters: [
            { type: 'html', subdir: 'CoverageReporter' },
            { type: 'cobertura', subdir: 'cobetura', file: 'cobertura.xml' },
            { type: 'text', subdir: '.', file: 'testResults.txt' },
            { type: 'text-summary', subdir: '.', file: 'testSummary.txt' }
        ]
    }

然后，我在构建定义中将覆盖结果发布为：

但是在构建摘要中，没有代码覆盖率选项卡来显示结果：

工件是使用数据创建的，因此可以正确下载和查看。

我已经看到很多帖子显示了“代码覆盖率”选项卡，但是我似乎无法显示它。请帮忙。

构建的输出：
