pycharm 和单元测试 - 构建项目 [英] pycharm and unittesting - structuring project

问题描述

我在我的一个大学项目中使用 pycharm，我想将它与 unittest 模块集成，但我在构建我的项目时遇到问题

I am using pycharm at one of my university projects and I wanted to integrated it with unittest module, but I have a problem with structuring my project

这个项目的一部分涉及生成抽象语法树，所以我创建了AST目录并将__init__.py放在那里，然后我创建了expression模块.我想把我的测试放在 test/ 子目录中，所以它看起来像这样:

Part of this project involves generating abstract syntax trees, so I created AST directory and put __init__.py there, then I created expression module. I wanted to put my tests in test/ subdirectory, so it would look like this:

AST/
  __init__.py
  expression.py
  test/
      some_test.py
  utils.py

现在我的 AST 中还有名为 symbol_table 的模块和名为 utils 的模块，示例测试类看起来像

now I have also module in my AST called symbol_table and module called utils, example test class looks like

import unittest
from ...AST import expression
from ...AST import utils


class ConstantExpressionTest(unittest.TestCase):

    def testConstantExpressionCheck(self):
        constantExpression = expression.ConstantExpression(17, 5, utils.TYPES.INT)
        self.assertTrue(constantExpression.check())

当我右键单击此文件并选择 Run Unittest in ... 时出现错误:

when I right click on this file and select Run Unittest in ... I am getting errors:

/usr/bin/python2.7 /home/xubuntu/Downloads/pycharm-2.7.2/helpers/pycharm/utrunner.py /home/xubuntu/Przedmioty/VI/kompilatory/tk-projekt/src/AST/test/test_constant_expression.py true
Testing started at 12:06 PM ...

    from ...AST import utils
ValueError: Attempted relative import in non-package

Process finished with exit code 1

我已经阅读了有关此问题的信息，如果我理解正确，则会将此文件视为顶级包中的文件，因此我无法使用任何相关导入.

I have read about this problem and if I understand this right, this file is treated as it would be in top-level package so I can't use any relative imports.

但如果是这样，我如何从 pycharm 运行单元测试并保持我当前的项目结构?

But if that is the case, how can I run unit-tests from pycharm and also keep my current project strcture?

如果我没记错的话，将测试放在子包中非常流行(http://as.ynchrono.us/2007/12/filesystem-structure-of-python-project_21.html) 所以一定有某种解决方案

If I am not mistaken, putting tests in sub-package is pretty popular (http://as.ynchrono.us/2007/12/filesystem-structure-of-python-project_21.html) so there must be some kind of solution

推荐答案

好吧，这有点傻，我发现 pycharm 将项目的根添加到路径中，这样我就可以从我的根使用正常导入项目.

Well, that is a bit silly, I found out that pycharm adds the root of the project to path so I can just use normal imports from the root of my project.

例如我可以写

from AST import expression in my some_test file

from AST import expression in my some_test file
