小编W2a*_*W2a的帖子

我有以下tests目录树：

tests/
  subfolder_1/
    test_1.py
  subfolder_2/
    subsubfolder/
      subsubsubfolder/
        test_2.py

py.test 只找到test_1.py. 我怎样才能让它找到test_2.py？

我通过网络进行了一些研究,发现了一些有用的代码.我改变了一下,试图捕获整个屏幕并生成一个我可以通过udp数据包发送的缓冲区:

#include <iostream>
#include <Windows.h>
#include <fstream>

void CapruteScreenAndSaveToFile()
{
    uint16_t BitsPerPixel = 24;
    uint32_t Width = GetSystemMetrics(SM_CXSCREEN);
    uint32_t Height = GetSystemMetrics(SM_CYSCREEN);

    // Create Header
    BITMAPFILEHEADER Header;
    memset(&Header, 0, sizeof(Header));
    Header.bfType = 0x4D42;
    Header.bfOffBits = sizeof(BITMAPFILEHEADER) + sizeof(BITMAPINFOHEADER);

    // Create Info
    BITMAPINFO Info;
    memset(&Info, 0, sizeof(Info));
    Info.bmiHeader.biSize = sizeof(BITMAPINFOHEADER);
    Info.bmiHeader.biWidth = Width;
    Info.bmiHeader.biHeight = Height;
    Info.bmiHeader.biPlanes = 1;
    Info.bmiHeader.biBitCount = BitsPerPixel;
    Info.bmiHeader.biCompression = BI_RGB;
    Info.bmiHeader.biSizeImage = Width * Height * (BitsPerPixel > 24 ? 4 : 3);

    // Capture screen …

我正在尝试使以下代码起作用：

from pytest_mock import mocker

class TestClass(mocker):
  def setup_method(self):
    self.some_mock = SomeAbstractClass()
    self.testsubject = ClassThatIsBeingTested(self.some_mock)

  def test_1(self):
    mocker.patch(self.some_mock, 'some_function', return_value=5)
    assert 5 == self.testsubject.function_that_internally_uses_the_mock()

但我得到一个 TypeError因为尝试实例化一个抽象类。

我怎么能嘲笑SomeAbstractClass？

我正在寻找一个短(和快)代码来检查一个字符串是否只包含数字,特别是寻找一个衬里.这是我的临时代码:

bool IsNumber(const std::string& str)
{
    int i = 0;
    for( ; i<str.size() && isdigit(str[i]); ++i);

    return ( i == str.size() );
}

以下代码：
