assertion

问题 Task: - given: a list of images filenames - todo: create a new list with filenames not containing the word "thumb" - i.e. only target the non-thumbnail images (with PIL - Python Imaging Library). I've tried r".*(?!thumb).*" but it failed. I've found the solution (here on stackoverflow) to prepend a ^ to the regex and to put the .* into the negative lookahead: r"^(?!.*thumb).*" and this now works. The thing is, I would like to understand why my first solution did not work but I don't. Since

问题 I'm wondering why the assert keyword is so underused in Java? I've almost never seen them used, but I think they're a great idea. I certainly much prefer the brevity of: assert param != null : "Param cannot be null"; to the verbosity of: if (param == null) { throw new IllegalArgumentException("Param cannot be null"); } My suspicion is that they're underused because They arrived relatively late (Java 1.4), by which time many people had already established their Java programming style/habit

问题 I have two Json objects as below need to be compared. I am using Newtonsoft libraries for Json parsing. string InstanceExpected = jsonExpected; string InstanceActual = jsonActual; var InstanceObjExpected = JObject.Parse(InstanceExpected); var InstanceObjActual = JObject.Parse(InstanceActual); And I am using Fluent Assertions to compare it. But the problem is Fluent assertion fails only when the attribute count/names are not matching. If the json values are different it passes. I require to

问题 I am getting the below sysmalloc error in running a C program. malloc.c:3096: sYSMALLOc: Assertion `(old_top == (((mbinptr) (((char *) &((av)->bins[((1) - 1) * 2])) - __builtin_offsetof (struct malloc_chunk, fd)))) && old_size == 0) || ((unsigned long) (old_size) >= (unsigned long) ((((__builtin_offsetof (struct malloc_chunk, fd_nextsize)) +((2 * (sizeof(size_t))) - 1)) & ~((2 * (sizeof(size_t))) - 1))) && ((old_top)->size & 0x1) && ((unsigned long)old_end & pagemask) == 0)' failed.

问题 I am testing a little sound library called clunk (http://sourceforge.net/projects/clunk/). I built that library for visual studio 11 and linked it in my visual studio project. When I try the test.cpp I am getting an assertion thrown by msvcr110d.dll. Does it have to do with my runtime librarie settings: It is " Multithreaded-Debug-DLL (/MDd) " ? In cmakelist.txt in clunk I added following line of code: set(CMAKE_CXX_FLAGS_DEBUG "${CMAKE_CXX_FLAGS_DEBUG} /MDd") I am still getting the message

问题 I want to restrict my users to edit/delete only the comments which they added. I found an example on youtube by a guy named intergral30 and followed his instruction. And now my admin account has the possibility to edit/delete everything, but my user has no access to his own comment. Here's the code: Resource class Application_Model_CommentResource implements Zend_Acl_Resource_Interface{ public $ownerId = null; public $resourceId = 'comment'; public function getResourceId() { return $this-

问题 I am trying to convert an OpenCV Image (of type cv::Mat) into matlab-style format as this is what the rest of the program quires. I am using the following code to do that: inline double* ConvertCVImageToMATLABImage(Mat &CvImage) { std::vector<cv::Mat> ColorChannels; // B, G, R channels cv::split(CvImage, ColorChannels); // remember to tranpose first because MATLAB is col-major!!! cv::transpose(ColorChannels[0], ColorChannels[0]); cv::transpose(ColorChannels[1], ColorChannels[1]); cv:

问题 my code are having some problems on my Visual Studio 2010 but not on DevCPP. Heres the situation, I used C++ STL set in my code to insert pair<string, double> but then I want my set to sort them using the value instead of the key, so I used a custom comparator to achieve this. struct sortPairSecond { bool operator()(const pair<string, double> &lhs, const pair<string, double> &rhs) { return lhs.second >= rhs.second; } }; The code works fine in DevCPP but encountered the Debug Assertion Failed

问题 I know that we can use ErrorCollector or soft assertions (AssertJ or TestNG) that do not fail a unit test immediately. How they can be used with Mockito assertions? Or if they can't, does Mockito provide any alternatives? Code sample verify(mock).isMethod1(); verify(mock, times(1)).callMethod2(any(StringBuilder.class)); verify(mock, never()).callMethod3(any(StringBuilder.class)); verify(mock, never()).callMethod4(any(String.class)); Problem In this snippet of code if a verification will fail,
