assert

I'm not much of an Eclipse guru, so please forgive my clumsiness. In Eclipse, when I call Assert.assertEquals(obj1,obj2) and that fails, how do I get the IDE to show me obj1 and obj2? I'm using JExample , but I guess that shouldn't make a difference. Edit : Here's what I see: (source: yfrog.com ) . If the information in the JUnit view is not enough for you, you can always set a exception breakpoint on, for example, java.lang.AssertionError. When running the test, the debugger will stop immediately before the exception is actually being thrown. Comparison with failure trace is not a easy task

作为一名web前端来入门dart，新语言和我们熟悉的js有所差异，写dart的过程中容易受到原有思维的影响，这里把dart和js做一个对比总结，方便查找和熟悉。 变量声明 var 关键字 dart和js都支持var关键字， 使用 var 关键词进行声明的时候，dart 会自动推断出 当前变量的类型，如果在变量声明的时候没有进行赋值，那么该类型就是动态的，类似于 TS 的 any。在类型推断上跟 TypeScript 是一致的。 众所周知，JavaScript 是一门弱类型的语言，而 Dart 是强类型的语言 但dart也支持一些弱类型，Dart 中弱类型有 var , Object 以及 dynamic 大家在学习dart的过程中，可能有疑问：同为弱类型， var , Object 以及 dynamic 有什么区别？ (1) var 初始可定义, 如果有初始值，那么其类型将会被锁定，定义之后不可改变类型 (2) Object 动态任意类型，编译阶段检查类型 (3) dynamic 动态任意类型，编译阶段不检查类型 var 初始化确定类型后不可更改类型， Object 以及 dynamic 可以更改类型 Object 编译阶段检查类型, 而 dynamic 编译阶段不检查类型 // 同样在声明的时候类型 var a = 'defalut'; Object b = 'defalut';

We have a C++ library. We are providing a custom assert and abandoning Posix NDEBUG and assert (back story below). The assert looks like so under Windows: # define CRYPTOPP_ASSERT(exp) { \ if (!(exp)) { \ std::ostringstream oss; \ oss << "Assertion failed: " << (char*)(__FILE__) << "(" \ << (int)(__LINE__) << "): " << (char*)(__FUNCTION__) \ << std::endl; \ std::cerr << oss.str(); \ DebugBreak(); \ } \ } The problem we are having is, we have to include <windows.h> , and it brings in a lot of extra cruft, even with WIN32_LEAN_AND_MEAN defined. Some of the extra cruft, like min and max , breaks

Assert 目录文件拷贝时候, Android 有个规定就是文件大小不能操作1M, 不然会抛文件太大的错误. 解决办法如下. 将文件拷贝到类文件下: 代码示意如下: private static boolean copyFile(Context ctx, String filename, String des) { InputStream instream = null; try { if (filename.contains("TUIRes.ndt")) { //这个文件超过1M instream = XmlFile.class .getResourceAsStream("TUIRes.ndt"); } else if (filename.contains("TUpdateRes.ndt")) { instream = XmlFile.class .getResourceAsStream("TUpdateRes.ndt"); } else { instream = ctx.getAssets().open(filename); } copyFile(des, instream); return true; } catch (Exception e) { return false; } } private static void copyFile(String

Preface In Swift, ENABLE_NS_ASSERTIONS is ignored, and whether assertions are on or off is dependent of SWIFT_OPTIMIZATION_LEVEL , see here for more information . assert() is active for -Onone assertionFailure() is active for -Onone precondition() is active for -Onone and -O preconditionFailure() is active for -Onone , -O and -Ounchecked fatalError() is active for -Onone , -O and -Ounchecked What I want to achieve Debug and Beta Builds should have assertions enabled , Release Builds should have assertions disabled . How I could do it I could write all my assertions in Swift via the

If I define import Control.Exception (assert) import Data.Char (ord) f :: String -> String f s = assert (all (`elem` letters) s) $ (letters!!) <$> (ix <$> s) where ix ch = (ord ch - ord 'A') letters = ['A'..'Z'] then if I execute f "AB.CD" in IHaskell, I get :10:7-12: Assertion failed as I would expect. But in all other settings, the assertion seems to be ignored. For example in GHCi (7.10.2) I get ghci>f "AB.CD" "AB*** Exception: Prelude.!!: negative index and if I put the expression in a program main :: IO () main = do print $ f "AB.CD" I get prgm: Prelude.!!: negative index "AB Why is my

pytest 1，最简单的示例 import pytest def test_case_01(): print("执行test01") assert 1 # 断言成功 def test_case_02(): print("执行test02") assert 0 # 断言失败 if __name__ == '__main__': pytest.main(['test_01.py']) 运行结果如下： pytest 1，最简单的示例 import pytest def test_case_01(): print("执行test01") assert 1 # 断言成功 def test_case_02(): print("执行test02") assert 0 # 断言失败 if __name__ == '__main__': pytest.main(['test_01.py']) 运行结果如下： 如图所示： 在执行完成之后先会显示test01.py，后面跟着.F 其中.代表执行成功，F代表执行失败，并且在下方会展示错误的提示 2，pytest使用步骤： 1，导入pytest 2，编写测试用例 一，无需在测试类下编写测试用例，可以直接编写测试函数 二，测试函数名必须包含test_ 开头,或者_test结尾； 3，在pytest框架下执行测试用例 在py文件内执行测试用例: pytest
