单元测试 VSTO 项目 [英] Unit Testing VSTO projects

问题描述

在我遵循的大多数单元测试教程中，它让我创建第二个单元测试项目，然后将测试项目中的解决方案/项目引用添加到另一个项目.

In most unit test tutorials I follow it has me create a second unit test project and then add a solution/project reference from the test project to the other project.

我有一个 VSTO 插件，当我添加参考时，我没有看到解决方案 > 项目下列出的任何内容.

I have a VSTO addin, and when I go to add the reference I don't see anything listed under Solution > Project.

这是为什么?我还能如何添加对插件项目的引用来测试它?

Why is this? How else can I add a reference to the addin project to test it?

推荐答案

如果这是您第一次进行单元测试，那么 VSTO 可能是一个陡峭的学习曲线.正如@Sam Holder 所建议的那样，您可能希望将一些逻辑放入单独的程序集中，以鼓励您将逻辑与与办公基础设施的交互分开.

If this is your first time at unit testing, then VSTO might be a steep learning curve. As suggested by @Sam Holder, you might want to put some of your logic into a separate assembly to encourage you to separate your logic from your interactions with the office infrastructure.

也就是说，虽然您无法使用添加对项目的引用的常规方法来添加项目，但您可以使用 Browse 添加对该项目的输出的引用 选项:

That said, whilst you can't add the project using the normal approach of adding a reference to the project, you can add a reference to the output from that project using the Browse option:

• 右键单击测试项目并选择添加引用".
• 在出现的框中，点击底部的浏览"按钮.
• 导航到 VSTO 项目的 bin\debug 文件夹并选择项目 dll.
• 点击确定.

显然，您必须构建插件才能使上述内容正常工作.

Obviously, you will have had to have built the addin for the above to work.

如果您开始尝试创建依赖于办公基础设施的对象，您将面临一些其他挑战.因此，您可能至少需要在测试项目中添加对 Microsoft.Office.Tools、Microsoft.Office.Tools.Common 的引用.

You're going to face some other challenges if you start trying to create objects that rely on the office infrastructure. So, at a minimum you might need to add references to Microsoft.Office.Tools, Microsoft.Office.Tools.Common into your test project.
