assert

Hallo! I'm looking for a way to add custom messages to assert statements. I found this questions Add custom messages in assert? but the message is static there. I want to do something like this: assert((0 < x) && (x < 10), std::string("x was ") + myToString(x)); When the assertion fails I want the normal output plus for example "x was 100". You are out of luck here. The best way is to define your own assert macro. Basically, it can look like this: #ifndef NDEBUG # define ASSERT(condition, message) \ do { \ if (! (condition)) { \ std::cerr << "Assertion `" #condition "` failed in " << __FILE__

I stumbled upon an informative article: http://cnicholson.net/2009/02/stupid-c-tricks-adventures-in-assert/ which pointed out a great number of problems that exist in my current suite of debugging macros. The full code for the final version of the macro is given near the end of the article if you follow the link. The general form as presented is like this (somebody please correct me if i am wrong in transposing it): #ifdef DEBUG #define ASSERT(cond) \ do \ { \ if (!(cond)) \ { \ ReportFailure(#cond, __FILE__, __LINE__, 0); \ HALT(); \ } \ } while(0) #else #define ASSERT(cond) \ do { (void

What is a good way to assert that two arrays of objects are equal, when the order of the elements in the array is unimportant, or even subject to change? The cleanest way to do this would be to extend phpunit with a new assertion method. But here's an idea for a simpler way for now. Untested code, please verify: Somewhere in your app: /** * Determine if two associative arrays are similar * * Both arrays must have the same indexes with identical values * without respect to key ordering * * @param array $a * @param array $b * @return bool */ function arrays_are_similar($a, $b) { // if the

NUnit 分三篇文章介绍，入门者可阅读文章，有基础者直接参考 官方文档 。初次写博客，望大家指点。 导航： 单元测试之NUnit一 单元测试之NUnit二 单元测试之NUnit三 本文介绍常用的NUnit属性特性和断言。 常用属性 更多属性参考官方文档 1. Test Attribute 标记一个方法为测试方法。 /// <summary> /// 简单标记方法为测试方法 /// </summary> [Test] public void Add() { Assert.AreEqual(4, 2 + 2); } /// <summary> /// 添加说明内容，等同于DescriptionAttribute属性 /// </summary> //[Test(Description = "这是说明内容")] [Test,Description("这是说明属性")] public void Add() { Assert.AreEqual(4, 2 + 2); } // 标记异步方法 [Test] public async Task AddAsync() { /* ... */ } // 如果测试方法有返回值，要使用ExpectedResult校验 [Test(ExpectedResult = 4)] public int TestAdd() { return 2 + 2; } //

The Go language creators write : Go doesn't provide assertions. They are undeniably convenient, but our experience has been that programmers use them as a crutch to avoid thinking about proper error handling and reporting. Proper error handling means that servers continue operation after non-fatal errors instead of crashing. Proper error reporting means that errors are direct and to the point, saving the programmer from interpreting a large crash trace. Precise errors are particularly important when the programmer seeing the errors is not familiar with the code. What is your opinion about this

Does anybody know why JUnit 4 provides assertEquals(foo,bar) but not assertNotEqual(foo,bar) methods? It provides assertNotSame (corresponding to assertSame ) and assertFalse (corresponding to assertTrue ), so it seems strange that they didn't bother including assertNotEqual . By the way, I know that JUnit-addons provides the methods I'm looking for. I'm just asking out of curiosity. I'd suggest you use the newer assertThat() style asserts, which can easily describe all kinds of negations and automatically build a description of what you expected and what you got if the assertion fails:

I'm trying to execute my test scripts using testNG and trying the below code, but 0 displayed against run, fail and skip in the console. Because of that I'm unable to verify the results in my script. Java: package com.demoaut.newtours.testcases; import org.testng.Assert; import org.testng.annotations.Test; //import junit.framework.Assert; public class TC002_CheckAssert { @Test public TC002_CheckAssert() { System.out.println("ajkcbh"); try { Assert.assertEquals("Pass", "Pass"); } catch(Exception e) { System.out.println("Exception:" + e.getLocalizedMessage()); } } } I am executing the above

今天同事问了我一个关于DD-WRT编译的问题，在link里面一个工具的时候出现了下面的错误： [root@localhost dhcpforwarder]# mipsel-linux-uclibc-gcc -o dhcpfwd -ffunction-sections -fdata-sections -Wl,--gc-sections src/parser.o src/main.o src/cfg.o src/recvfromflags.o src/output.o /home/ipdslam_users/yzeng/dd-wrt/toolchains/4.1.0-uclibc-0.9.28/bin/../lib/gcc/mipsel-linux-uclibc/4.1.0/../../../../mipsel-linux-uclibc/bin/ld: BFD 2.16.1 assertion fail /home/openwrt/trunk/openwrt/toolchain_build_mipsel/binutils-2.16.1/bfd/elfxx-mips.c:2562 src/main.o: In function `execRelay': main.c:(.text+0x590): undefined reference to `__assert_fail' main.c:

First one - is what NDEBUG somehow already defined by default, so asserts don't work until you #undef it. Second one - they do they work, but i receive no logging in DDMS. If there is some android specific one assert.h? Or i just do something wrong? If you want to compile your code with asserts then you can do it in three ways: use NDK_DEBUG=1 argument in ndk-build commandline add android:debuggable="true" to < application > tag in AndroidManifest.xml add APP_OPTIM := debug to your Application.mk file - this will also disable optimizations and will compile with debug symbols ylchung Usually
