assertions

问题 Is there a way in Z3 to prove/show that a given model is unique and that no other solution exists? A small example to demonstrate (declare-const a1 Int) (declare-const a2 Int) (declare-const a3 Int) (declare-const b1 Int) (declare-const b2 Int) (declare-const b3 Int) (declare-const c1 Int) (declare-const c2 Int) (declare-const c3 Int) (declare-const ra Int) (declare-const rb Int) (declare-const rc Int) (declare-const r1 Int) (declare-const r2 Int) (declare-const r3 Int) (assert (>= a1 0))

问题 I am parsing an xml file and putting its parsed values in a table view.The table view has only one section.But i am getting following exception: 2013-10-14 15:21:57.250 tableview[6068:907] * Assertion failure in -[UITableView _endCellAnimationsWithContext:], /SourceCache/UIKit/UIKit-2380.17/UITableView.m:909 2013-10-14 15:22:11.227 tableview[6068:907] Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'attempt to insert row 0 into section 0, but there are

问题 In my Python package I have a function I use to create validated instances of my class, with something like @staticmethod def config_enigma(rotor_names, window_letters, plugs, rings): comps = (rotor_names + '-' + plugs).split('-')[::-1] winds = [num_A0(c) for c in 'A' + window_letters + 'A'][::-1] rngs = [int(x) for x in ('01.' + rings + '.01').split('.')][::-1] assert all(name in rotors for name in comps[1:-1]) assert comps[-1] in reflectors assert len(rngs) == len(winds) == len(comps)

问题 I'm trying to just preg content between html tags, I'm trying this simple assertion pattern and I don't understand why it doesn't match this string. <a href=http://url.com title="link">this is a ling</a> (?<=<a.*>)([ \w]*)(?=<.*\/a>) Debuggex Demo 回答1: Lookbehinds on debuggex (PCRE, Javascript and Python) cannot be of variable width, meaning that you can use (?<=<a>) which has a fixed width (3 characters) but not something that can vary in length (?<=<a.*>) (can have 3 characters, or 4, or 5,

问题 Hi I know that what I am about to ask has been asked before by others however I am still unclear about those that has been posted online hence I am posting this Question to clarify my doubts. Hope that you guys can help me out with it. Currently I am using Microsoft Visual Studio 2013 Premium. I am using the record and play functions. I record some actions and a few verification points. Now the script will immediately stop when an verification point fails. However I want the script to

问题 This question already has answers here : Brian Goetz's improper publication (2 answers) Closed 3 years ago . Listing 3.15. Class at Risk of Failure if Not Properly Published. public class Holder { private int n; public Holder(int n) { this.n = n; } public void assertSanity() { if (n != n) throw new AssertionError("This statement is false."); } } My first question is why javac not optimize if (n != n) ? The following is my demo for the example public class TestSync { private int n; public

问题 Given XSD: <xs:element name="color"> <xs:complexType> <xs:attribute name="type"> <xs:simpleType> <xs:restriction base="xs:string"> <xs:enumeration value="white"/> <xs:enumeration value="black"/> <xs:enumeration value="red"/> <xs:enumeration value="green"/> </xs:restriction> </xs:simpleType> </xs:attribute> <xs:attribute name="number" use="optional/> </xs:complexType> </xs:element> How would I write an assertion so that if <color> has @type white or black, it cannot also have the @number

问题 I'm an architect from a strong JavaScript background, but I did some .NET and Java in the past. However, I wanted to put a hand on ActionScript3, which I was promised that is very related to JavaScript. As a startup project I took on myself to try port to ActionScript3 one of my favorite assertion utils - should.js - that makes your test codes really pleasant to read. Updated: 2013-02-19 I saw I confuse with my abstract speaking, so I replaced some of the post with the concrete question in

问题 I created JMeter test when I use JDCB query which returns NUMBER value which I set to variable e.g. called employeeID. I know that it is possible to use Response Assertion and I can verify if my variable: employeeID_1 is equal to specific expected value. How can I verify if my variable is > 0 instead? 回答1: The most straight forward would be using BeanShell Assertion like this: int myNumber = -1; try { myNumber = Integer.parseInt(vars.get("employeeID_1")); } catch(NumberFormatException e) { /*
