如何使用 dotnet test 通过单个通过/失败摘要从多个库运行测试

Question

如果我在代码库中有多个测试库，如何使用 dotnet test 运行单元测试？

我可以运行dotnet test，它甚至会跨多个库查找并运行所有测试，但它会运行并报告每个测试库独立运行：

$ dotnet test
Test run for C:\Users\mark\Documents\Redacted.Test\bin\Debug\netcoreapp2.1\Redacted.Test.dll(.NETCoreApp,Version=v2.1)
Test run for C:\Users\mark\Documents\Redacted\Redacted.SqlAccess.Test\bin\Debug\netcoreapp2.1\Redacted.SqlAccess.Test.dll(.NETCoreApp,Version=v2.1)
Microsoft (R) Test Execution Command Line Tool Version 16.2.0-preview-20190606-02

Starting test execution, please wait...
Starting test execution, please wait...

Test Run Successful.
Total tests: 59
     Passed: 59
 Total time: 3.1779 Seconds
Test run for C:\Users\mark\Documents\Redacted\Redacted.RestApi.Tests\bin\Debug\netcoreapp2.1\Redacted.RestApi.Tests.dll(.NETCoreApp,Version=v2.1)

Starting test execution, please wait...

Test Run Successful.
Total tests: 99
     Passed: 99
 Total time: 9.8155 Seconds

Test Run Successful.
Total tests: 25
     Passed: 25
 Total time: 21.2894 Seconds

在这个例子中，有两个测试库，所以我得到两个测试结果输出。

如果代码已经编译，这可能会正常工作，但在干净的构建中，编译器会产生大量输出。这很容易导致测试运行摘要之一滚动到屏幕的可见部分。

如果测试运行失败，那就有问题了。

如何将所有单元测试合并为一个通过/失败摘要？

例如，在 .NET 4.x 上，我可以使用 xUnit.net 的控制台运行器将所有测试库作为一个套件运行：

$ ./packages/xunit.runner.console.2.4.0/tools/net461/xunit.console BookingApi.UnitTests/bin/Debug/Ploeh.Samples.Booking
Api.UnitTests.dll BookingApi.SqlTests/bin/Debug/Ploeh.Samples.BookingApi.SqlTests.dll
xUnit.net Console Runner v2.4.0 (64-bit Desktop .NET 4.6.1, runtime: 4.0.30319.42000)
  Discovering: Ploeh.Samples.BookingApi.UnitTests
  Discovered:  Ploeh.Samples.BookingApi.UnitTests
  Starting:    Ploeh.Samples.BookingApi.UnitTests
  Finished:    Ploeh.Samples.BookingApi.UnitTests
  Discovering: Ploeh.Samples.BookingApi.SqlTests
  Discovered:  Ploeh.Samples.BookingApi.SqlTests
  Starting:    Ploeh.Samples.BookingApi.SqlTests
  Finished:    Ploeh.Samples.BookingApi.SqlTests
=== TEST EXECUTION SUMMARY ===
   Ploeh.Samples.BookingApi.SqlTests   Total:  3, Errors: 0, Failed: 0, Skipped: 0, Time: 3.816s
   Ploeh.Samples.BookingApi.UnitTests  Total:  7, Errors: 0, Failed: 0, Skipped: 0, Time: 0.295s
                                              --          -          -           -        ------
                                 GRAND TOTAL: 10          0          0           0        4.111s (5.565s)

注意这如何在屏幕底部生成单个摘要，以便我可以立即查看我的测试是通过还是失败。

Answer 1

使用dotnet vstest 运行多个程序集。

 PS> dotnet vstest --help

Microsoft (R) Test Execution Command Line Tool Version 15.9.0
Copyright (c) Microsoft Corporation.  All rights reserved.

Usage: vstest.console.exe [Arguments] [Options] [[--] <RunSettings arguments>...]]

Description: Runs tests from the specified files.

Arguments:

[TestFileNames]
      Run tests from the specified files. Separate multiple test file names
      by spaces.
      Examples: mytestproject.dll
                mytestproject.dll myothertestproject.exe
...

请注意，此方法要求您指向已编译的程序集（而不是 dotnet test，后者希望您指向项目文件，并且可以选择先为您构建内容）。
