unit-testing - 如何使用 dotnet test 运行来自多个库的测试，并带有单个通过/失败摘要

Question

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

我可以跑 dotnet test ，它甚至会在多个库中查找并运行所有测试，但它会独立运行并报告每个测试库:

$ 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)

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)

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，但是在干净的构建中，编译器会有很多输出。这很容易导致 之一测试运行摘要以滚动超过屏幕的可见部分 .

如果测试运行失败，那就是一个问题。

如何将所有单元测试折叠为单个通过/失败摘要？

例如，在 .NET 4.x 上，我可以使用 xUnit.net 的控制台运行程序将所有测试库作为单个套件运行:

$ ./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)

注意这是如何产生 单个总结在屏幕底部，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)。
