Đơn vị kiểm tra với dự án 3,5 kiểm tra Net không làm việc với VS 2012

Question

Tôi có một Visual Studio 2012 tại mà tôi có (giả sử được đơn giản) 2 dự án:

• MyProject (lớp thư viện)
• MyProject .Test (Dự án thử nghiệm MS)

Vì tôi phải nhắm mục tiêu .Net 3.5, I retarget the test project's framework.

Tuy nhiên, tại thời điểm này, kiểm tra đơn vị dừng lại để hoạt động (nếu tôi rời khỏi 4.5, nó hoạt động).

Cụ thể, QTAgent.exe treo:

[Window Title] 
QTAgent.exe 

[Main Instruction] 
QTAgent.exe has stopped working 

[Content] 
A problem caused the program to stop working correctly. Please close the program. 

[Close the program] [Debug the program] 

Trong cửa sổ đầu ra của Visual Studio, tôi có thể thấy:

Nếu tôi đính kèm một debugger để quá trình QTAgent.exe, tôi có thể thấy ngăn xếp này:

Có ai đó ha s một ý tưởng tại sao thiết lập của tôi không hoạt động, và làm thế nào để sửa chữa nó?

Đối với một chút nền, tôi đang tạo thử nghiệm đơn vị SharePoint 2010, vì vậy tôi thiết lập dự án thử nghiệm để nhắm mục tiêu .Net 3.5 (SharePoint không hoạt động với CLR 4).

Tôi cũng thiết lập dự án thử nghiệm để chạy trong máy chủ 64 bit.

Answer 1

Tôi thực sự không thể giải thích tại sao, nhưng tôi xóa tệp mysolution.v11.suo, các thử nghiệm bắt đầu hoạt động.

Thực ra, sự khác biệt là tôi không có tệp cài đặt thử nghiệm nữa (.testsettings).

Tôi đã phải xóa tệp bản ghi, vì VS 2012 không cho phép bỏ chọn tệp cài đặt thử nghiệm.

Tôi cũng phải ép buộc chế độ X64 (yêu cầu của ứng dụng lưu trữ của tôi, SharePoint). nhưng lần này, thay vì đặt chế độ trong tệp kiểm tra tệp, tôi đã đặt sử dụng TEST->TEST SETTINGS->DEFAULT PROCESSOR ARCHITECTURE-> X64

Answer 2

Tôi không biết môi trường của bạn, nhưng trong tôi, nó chỉ hoạt động trong trường hợp đó, khi thư mục đầu ra không nằm trong thư mục dự án. Tôi có nghĩa là ".. \ Debug" không hoạt động, nhưng "bin \ Debug" hoạt động. Lỗi ít nhiều giống với những gì bạn nhận được. (Ít nhất là trong env của tôi.)
