實例化機器人框架中的C＃對象

Question

我正在尋找使用Robot Framework來測試.NET應用程序，並且我正在努力瞭解Robot Framework如何實例化C＃對象，以用於測試。

我與演出的C＃應用​​程序非常簡單：

SystemUnderTest solution 
|_ DataAccess project (uses Entity Framework to connect to database) 
| |_ SchoolContext class 
| 
|_ Models project 
    |_ Student class 
| 
|_ SchoolGrades project (class library) 
    |_ SchoolRoll class 
     |_ AddStudent(Student) method 

我想從機器人框架執行傳遞addStudent方法，傳遞應保存到數據庫中的Student對象。

我用Python編寫的測試庫，它使用Python for .NET (pythonnet)調用.NET應用程序：

import clr 
import sys 

class SchoolGradesLibrary (object): 

    def __init__(self, application_path, connection_string): 

     self._application_path = application_path 
     sys.path.append(application_path) 

     # Need application directory on sys path before we can add references to the DLLs. 
     clr.AddReference("SchoolGrades") 
     clr.AddReference("DataAccess") 
     clr.AddReference("Models") 

     from SchoolGrades import SchoolRoll 
     from DataAccess import SchoolContext 
     from Models import Student 

     context = SchoolContext(connection_string) 
     self._schoolRoll = SchoolRoll(context) 

    def add_student(self, student): 

     self._schoolRoll.AddStudent(student) 

從Python中調用這個工程：

from SchoolGradesLibrary import SchoolGradesLibrary 
import clr 

application_path = r"C:\...\SchoolGrades\bin\Debug" 
connection_string = r"Data Source=...;Initial Catalog=...;Integrated Security=True" 

schoolLib = SchoolGradesLibrary(application_path, connection_string) 

# Have to wait to add reference until after initializing SchoolGradesLibrary, 
# as that adds the application directory to sys path. 
clr.AddReference("Models") 
from Models import Student 

student = Student() 
student.StudentName = "Python Student" 
schoolLib.add_student(student) 

我有點丟失到如何從Robot Framework做同樣的事情。這是我到目前爲止有：

*** Variables *** 
${APPLICATION_PATH} = C:\...\SchoolGrades\bin\Debug 
${CONNECTION_STRING} = Data Source=...;Initial Catalog=...;Integrated Security=True 

*** Settings *** 
Library SchoolGradesLibrary ${APPLICATION_PATH} ${CONNECTION_STRING} 

*** Test Cases *** 
Add Student To Database 
    ${student} =   Student 
    ${student.StudentName} = RF Student 
    Add Student   ${student} 

當我運行這一點，失敗，錯誤消息：No keyword with name 'Student' found.

我如何可以創建Robot Framework的一個Student對象，傳遞給學生添加關鍵字？測試中還有其他明顯的錯誤嗎？

C＃應用程序使用.NET 4.5.1編寫，Python版本爲3.5，Robot Framework版本爲3.0。

Answer 1

由於Student是一個類而不是關鍵字，因此您可能無法直接實例化沒有輔助工具的機器人中的Student。

最簡單的解決方案是創建在SchoolGradesLibrary關鍵字創建學生：

... 
import clr 
clr.AddReference("Models") 
from Models import Student 
... 

class SchoolGradesLibrary (object): 
    ... 
    def create_student(name=None): 
     student = Student() 
     if name is not None: 
      student.StudentName = name 
     return student 
    ... 

然後，您可以用在你的測試用例像一個正常的關鍵字。
