assertions

问题 If I activate assertions following the Oracle documentation ClassLoader.getSystemClassLoader().setDefaultAssertionStatus(true); ClassLoader.getSystemClassLoader().setPackageAssertionStatus("richtercloud.java.assertion.ignored", true); System.out.println(String.format("desired assertion status: %b", NewMain.class.desiredAssertionStatus())); assert false; System.out.println("assertion has been ignored"); in the main method of a class richtercloud.java.assertion.ignored.NewMain , I see from the

问题 I have a simple ACL configures in an acl.global.php like this: return [ 'acl' => [ 'roles' => [ 'guest' => null, 'member' => 'guest', 'admin' => 'member' ], 'resources' => [ 'allow' => [ 'Application\Controller\Index' => ['all' => 'member'], 'Application\Controller\Error' => ['all' => 'member'], 'Item\Controller\Process' => [ 'index' => 'member', 'create' => 'member', 'showItem' => 'member', // website.tld/item/:id 'showList' => 'member' // website.tld/list-items ] ] ], ] ]; A parser iterates

问题 I'm using a MailReaderSampler which gets all the messages from given email ID. All the emails have a verification token in it. For now, the token is being passed on the subject of the mail. So the Response Data will have : Date:-- To: -- From: -- Subject: token : someToken I have defined a Token value in User Defined Variables and I'm using Response assertion to check if the mail contains the Token . So it checks for all the sub-results(all emails). Now whenever an email contains the token,

问题 I have a Pixel-C that I am developing for. My minimum API level is 21, which is also the level at which ART replaced Dalvik. I have tried both of: adb shell setprop dalvik.vm.enableassertions all adb shell setprop debug.assert 1 And they seem to execute successfully. I have placed assert false : "assertions are active!"; in my onStart, and I am not seeing any stack traces in logcat. I would expect the app to exit immediately after I install and run it. Please tell me how to get this assertion

问题 I do some checking of arguments in my classes in php using exception-throwing functions. I have functions that do a basic check ( === , in_array etc ) and throw an exception on false. So I can do assertNumeric($argument, "\$argument is not numeric."); instead of if ( ! is_numeric($argument) ) { throw new Exception("\$argument is not numeric."); } Saves some typing I was reading in the comments of the php manual page on assert() that As noted on Wikipedia - "assertions are primarily a

问题 I suspect some ASSERTION code is having side effects. I'd like to switch off ASSERT without making any other changes to how my code is compiled. I'm using MSVS2008. Switching from debug to release won't do as that will alter how memory is initialised. 回答1: Put this at the top of your header files after the inclusions of cassert (or a include that includes cassert ) #undef assert #define assert(x) ((void)0) Which redefines the assert marco so that it expands to nothing. 回答2: If you mean assert

问题 In my previous question I wanted to use static_assert to restrict a template parameter to be a specific subtype. The question was answered, the code for archieving that is as follows: template <typename T> struct X { static_assert(std::is_base_of<Y,T>::value,"T must be derived from Y!"); }; Now, I want to make the error message more concise. I.e., I want to state which type is violating this constraint. E.g., if class A is not derived from Y and someone instanciates X<A> , then the error

问题 I've been bit a few times by Java assert statements that didn't fail in the JUnit test suite because assertions weren't enabled in JUnit's JVM instance. To be clear, these are "black box" assertions inside implementations (checking invariants, etc) not the assertions defined by the JUnit tests themselves. Of course, I'd like to catch any such assertion failures in the test suite. The obvious solution is to be really careful to use -enableassertions whenever I run JUnit, but I'd prefer a more

问题 Is there convenient way for using asserts within the kernels invocation on device mode? Thanks, in advance. 回答1: CUDA now has a native assert function. Use assert(...) . If its argument is zero, it will stop kernel execution and return an error. (or trigger a breakpoint if in CUDA debugging.) Make sure to include "assert.h". Also, this requires compute capability 2.x or higher, and is not supported on MacOS. For more details see CUDA C Programming Guide, Section B.16. The programming guide

问题 I was trying with a simple code using org.testng.Assert to assert 2 use-cases. In the first use-case I am asserting 2 unequal values which Fail correctly. But in the second use-case when I am asserting 2 unequal values within the try-catch block, the result is always returned as Pass My code is as follows: package demo; import org.testng.Assert; import org.testng.annotations.Test; public class Q43710035 { @Test public void test1() { System.out.println("Within test1"); int a = 12; int b =20;
