实例化机器人框架中的C＃对象

问题描述：

我正在寻找使用Robot Framework来测试.NET应用程序，并且我正在努力了解Robot Framework如何实例化C＃对象，以用于测试。实例化机器人框架中的C＃对象

我与演出的C＃应用程序非常简单：

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

我想从机器人框架执行传递addStudent方法，传递应保存到数据库中的Student对象。

我用Python编写的测试库，它使用Python for .NET (pythonnet)调用.NET应用程序：

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)

从Python中调用这个工程：

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)

我有点丢失到如何从Robot Framework做同样的事情。这是我到目前为止有：

*** 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}

当我运行这一点，失败，错误消息：No keyword with name 'Student' found.

我如何可以创建Robot Framework的一个Student对象，传递给学生添加关键字？测试中还有其他明显的错误吗？

C＃应用程序使用.NET 4.5.1编写，Python版本为3.5，Robot Framework版本为3.0。

答

由于Student是一个类而不是关键字，因此您可能无法直接实例化没有辅助工具的机器人中的Student。

最简单的解决方案是创建在SchoolGradesLibrary关键字创建学生：

... 
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 
    ...

然后，您可以用在你的测试用例像一个正常的关键字。

${student}= create student Inigo Montoya

工作就像一个魅力，谢谢。 –
