软件自动化测试脚本如何编写,编写自动化测试脚本的几点注意事项我们需要自动化测试脚本的原因：1、验收测试是一项非常复杂和费力的被用来确保软件质量的环节。它的目的就是使软件能得到充分运行并且能使其符合原始需求。2、测试的目的无非就是满足了两个结果：测试通过或测试不通过。为了能实现每个测试结果，必须要明确每个测试用例。并且对于整个系统而言在合同中必须定义测试用例的失败标准，而且这个失败标准数必须是可接受的。3、测试用例的通过条件必须有一个清晰的标准，标准可以被定... 阅读详情

函数一开始是这样的



char *g_pData = NULL;

g_uFileLength = 0;

bool Dc(LPWSTR infile)

{

	_wfopen_s(&fp_open, infile, L"rb+");

	

	fseek(fp_open, 0, SEEK_END);

	long lSize = ftell(fp_open); //获取文件大小



	rewind(fp_open);//回到文件头

	

	char * buffer = (char*)malloc(sizeof(char*)*lSize); //分配内存存储整个文件

	

	size_t result = fread(buffer, sizeof(char*), lSize, fp_open); // 将文件拷贝到buffer中



	g_uFileLength = lSize - 888;



	g_pData = new char[(unsigned int)g_uFileLength];

	memcpy(g_pData, buffer, (size_t)g_uFileLength);



	fclose(fp_open);

	delete[] buffer;

    retrun true;

}

现在由于一些原因要改成以下的读取方法，分开一段一段地

bool Dc(LPWSTR infile)

{

	HANDLE HinFile = CreateFile(infile, GENERIC_READ, FILE_SHARE_READ, NULL, OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL, NULL);

	ULONGLONG flen = SetFilePointer(HinFile, 0, NULL, FILE_END);//文件字节数

	g_pData = new char[(unsigned int)flen -888];

	memset(g_pData, 0, sizeof(g_pData));

	SetFilePointer(HinFile, 0, NULL, FILE_BEGIN);//重置到文件头



	if (HinFile != INVALID_HANDLE_VALUE)

	{

		LARGE_INTEGER llFileSize;

		if (GetFileSizeEx(HinFile, &llFileSize))

		{

			size_t ulBytesToRead = 5 * 1024 * 1024;

			HANDLE hHeap = GetProcessHeap();

			LARGE_INTEGER llReadPos = { 0 };

			while (llReadPos.QuadPart < llFileSize.QuadPart)

			{

				BOOL bResult;

				DWORD dwBytesRead = 0;

				DWORD dwBytesWritten = 0;



				LONGLONG llBytesRest = llFileSize.QuadPart - llReadPos.QuadPart;

				if (llBytesRest < (LONGLONG)ulBytesToRead)

				{

					ulBytesToRead = (size_t)llBytesRest;

				}

				char *lpBytes = (char *)HeapAlloc(hHeap, HEAP_ZERO_MEMORY, ulBytesToRead);

				if (lpBytes == NULL)

				{

					break;

				}



				bResult = ReadFile(HinFile, lpBytes, ulBytesToRead, &dwBytesRead, NULL);

				if (!bResult || (dwBytesRead < ulBytesToRead))

				{

					HeapFree(hHeap, 0, lpBytes);

					break;

				}

		//==》关键在这里

                //strcat_s(g_pData, g_uFileLength, lpBytes); //拼接后最终的g_pData数据不正常

				//bResult = WriteFile(HoutFile, lpBytes, dwBytesRead, &dwBytesWritten, NULL); //尝试写入文件，数据正常

				

				//if (!bResult || (dwBytesWritten < dwBytesRead))

				//{

				//	HeapFree(hHeap, 0, lpBytes);

				//	break;

				//}

				llReadPos.QuadPart += dwBytesRead;

				HeapFree(hHeap, 0, lpBytes);

			}

		}

	}

	CloseHandle(HinFile);

	return true;

}
