I'm testing a client-server communication through a TCP socket. I wrote the server in C and I'm running it on a Linux machine and I'm using nc as a client for test. The server, after an initial exchange of messages with the client, sends some messages periodically to the client without getting any response. If I kill the client, I expect that the first send() done by the server f
我正在通过TCP套接字测试客户端 - 服务器通信。 我用C语言编写服务器,并在Linux机器上运行它,并使用nc作为客户端进行测试。 在与客户端初始交换消息之后,服务器定期向客户端发送一些消息而没有得到任何响应。 如果我终止了客户端,我期望服务器完成的第一个send()失败并且发生EPIPE错误,但是这仅在客户端离开后第二次send()才会生效! 我杀死客户端后的第一个send()函数能够成功发送1100个字节给(我想是关闭的)套接
I have 2 concerns about my unit test method: Do I test too much in one test method? How can my test method name reflect all test expectations? I asked myself when my method name says: ReturnInvalidModelState , then my 2 other Asserts are not correct. At least concerning the method name... [Test] public void Create_TemplateAlreadyExists_ReturnInvalidModelState() { // ARRANGE Templa
我有两个关于我的单元测试方法的问题: 我在一种测试方法中测试过多吗? 我的测试方法名称如何反映所有测试期望? 我问自己什么时候我的方法名称说: ReturnInvalidModelState ,然后我的两个其他Asserts不正确。 至少关于方法名称... [Test] public void Create_TemplateAlreadyExists_ReturnInvalidModelState() { // ARRANGE TemplateViewModel templateViewModel = new TemplateViewModel { Name =
This is an interview question. We are given dimensions of various rectangles, we have to find out the area(minimum) of rectangle that can enclose all of them? rectangles can be rotated also . test case:- input: 3 //number of rectangles 8 8 4 3 3 4 output: 88 11x8: + - - - - - - + + - + | | | | | | | | | | + - + | | + - + | |
这是一个面试问题。 我们给出了各种矩形的尺寸,我们必须找出可以包含所有矩形的矩形区域(最小)? 矩形也可以旋转。 test case:- input: 3 //number of rectangles 8 8 4 3 3 4 output: 88 11x8: + - - - - - - + + - + | | | | | | | | | | + - + | | + - + | | | | | | | | + - - - - - - + + - + 我在最小的可能区域中查看类似
Every time I write a simple lexer and parser, I stumble upon the same question: how should the lexer and the parser communicate? I see four different approaches: The lexer eagerly converts the entire input string into a vector of tokens. Once this is done, the vector is fed to the parser which converts it into a tree. This is by far the simplest solution to implement, but since all tokens ar
每次我写一个简单的词法分析器和解析器时,我都会遇到同样的问题:词法分析器和解析器应该如何通信? 我看到四种不同的方法: 词法分析器急切地将整个输入字符串转换为一个标记向量。 一旦完成,矢量将被馈送到解析器,该解析器将其转换为树。 这是迄今为止最简单的解决方案,但由于所有令牌都存储在内存中,因此浪费了大量空间。 每当词法分析器找到一个标记时,它就会在解析器上调用一个函数,传递当前的标记。 根据我
Is there anyone out there who knows how to handle the behavior of Safari Web Browser that sets the current page to the previous page whenever users were pressing backspace key? I'm currently experiencing this issue on Mac OSX Lion 10.7.2 and a silverlight application whenever our users were trying to correct fields using the backspace/Delete key. I've had this problem in the past too.
有谁知道如何处理Safari浏览器的行为,当用户按下退格键时,将当前页面设置为上一页? 我目前在Mac OSX Lion 10.7.2和Silverlight应用程序中遇到此问题,只要我们的用户试图使用退格/删除键来更正字段。 我也有过这个问题。 我花了一个星期左右的时间试图想出一个解决方案,并且最终解决这个问题的最佳方法(我从来没有发现“修复”可以这么说)如下: 使用Javascript挂起所有退格键关闭事件。 不允许任何退格事件到达Silve
I want to sort a list in c#, by a property of the objects stored in it. I have this: if (sortColumn == "Login") { if (sortDir == "ASC") { filteredList.Sort((x, y) => string.Compare(x.Login, y.Login, true)); } else { filteredList.Sort((x, y) => string.Compare(y.Login, x.Login, true)); } } And it works fine, but I want to do it more generic, in orde
我想在c#中对存储在其中的对象的属性进行排序。 我有这个: if (sortColumn == "Login") { if (sortDir == "ASC") { filteredList.Sort((x, y) => string.Compare(x.Login, y.Login, true)); } else { filteredList.Sort((x, y) => string.Compare(y.Login, x.Login, true)); } } 它工作正常,但我想要更通用一些,以便不必知道该字段进行排序。 我有这样的想法: //With s
I have been facing a very unique problem. I am using a System.Timers.Timer which triggers a method every minute. Gradually, I came to know the time interval is not constant. For testing and ensuring the issue, i just run a timer which elapsed a function every minute. And the output was shocking, the timer interval seconds are not constant. They are changing thus so creating an issue. 12/13
我一直面临一个非常独特的问题。 我正在使用每分钟触发一个方法的System.Timers.Timer。 渐渐地,我开始知道时间间隔不是恒定的。 为了测试和确保问题,我只需运行一个定时器,它每分钟都会运行一个函数。 并且输出令人震惊,定时器间隔秒数不是恒定的。 他们正在改变,因此造成了一个问题。 12/13/2016 3:39:26 PM 12/13/2016 3:40:25 PM 12/13/2016 3:41:25 PM 12/13/2016 3:42:25 PM 12/13/2016 3:43:25 PM 12/13/2016
I have a question about the usage of System.Timers.Timer in my .NET applications. I have three different events, one triggers every second, another triggers every minute and the last one triggers every half hour. Is it better, performance wise, to have one timer or three? The way to do it with one timer is to check ElapsedEventArgs ' SignalTime and compare it to a previously measured ti
我有一个关于System.Timers.Timer在我的.NET应用程序中的用法的问题。 我有三个不同的事件,一个触发每秒,另一个触发每分钟,最后一个触发每半小时。 有一个或三个计时器是更好还是更好? 用一个定时器做的方法是检查ElapsedEventArgs的SignalTime并将其与先前测量的时间进行比较。 当然,如果你已经改变了日期时间,这并不是很有效,但这不是问题。 基本上它每隔一秒钟就过去一次,我检查一分钟或半小时是否已经过去了
I am making a program which has to check a data base once on every 30 or 60 minutes and display the results, if there are any, in the windows form interface. Of course, the other functions which the from provides access to, should still be usable while the data base check is being executed. To this end, I am using System.Timers.Timer which executes a method on a different thread from the UI one
我正在制作一个程序,每30或60分钟检查一次数据库,并在Windows窗体界面中显示结果(如果有的话)。 当然,在执行数据库检查时,from提供的其他函数仍应该可用。 为此,我使用System.Timers.Timer,它在UI的另一个线程上执行一个方法(如果使用这种方法出现问题,请随时评论它)。 我写了一个小而简单的程序来测试热门的工作,但只注意到我无法真正将Interval设置为1分钟以上(我需要30分钟到1小时)。 我想出了这个解决方案
