问题 Tryng out some smalltalk + TDD + "good practices" I've run into a kinda ugly block: How do I do an assertion in GNU Smalltalk? I'm just looking for a simple ifFalse: [Die] kind of thing 回答1: This is the code for assert: from Squeak (which I recommend you use rather than GNU): assert: aBlock "Throw an assertion error if aBlock does not evaluates to true." aBlock value ifFalse: [AssertionFailure signal: 'Assertion failed'] 回答2: as well as self assert: [ ... some block ] works for blocks & non

问题 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

Is there a way how to continue after Debug.Assert() from the code?

问题 My code operates on data which "should" be correct. However during development there are occasions when I obtain invalid data. When that happens I would like to raise the debug assert and, if user choose to continue, the code would filter out the invalid records and continue to operate on "safe" data. // assert incorrect data Debug.Assert(person.Items.All(item => item.IsValid), "Inconsistent data!"); // operate on filtered data this.ItemViewModels = new ObservableCollection<ItemViewModel>(

问题 I am working on E2E tests and my goal is to compare two arrays. I set these arrays so that they are identical. The problem is that Protractor doesn't think they are same.

Assertion fail message for string contains substring [duplicate]

阅读更多关于 Assertion fail message for string contains substring [duplicate]

This question already has answers here : AssertContains on strings in jUnit (7 answers) Closed 6 years ago . I have done a lot of functional testing on text outputs on text generating software lately, an find myself writing a lot of assertTrue(actualString.contains(wantedString)); However, the message for when this fails is something non-descriptive like Expected [true], but was [false] An alternative is to include a custom fail message as String failMsg = String.format("Wanted string to contain: %s, Actual string: %s", wantedString, actualString); assertTrue(failMsg, actualString.contains

Cobertura coverage and the assert keyword

阅读更多关于 Cobertura coverage and the assert keyword

问题 My line coverage for unit tests measured by Cobertura is suffering, because I have assert statements which are not covered in tests. Should I be testing assert ions, and is there any way to get Cobertura to ignore them so they do not affect my test coverage? 回答1: The line coverage of your Java assert statements should be simply covered by running your test suite with assertions enabled, i.e., giving -ea as argument to the jvm. If you do this, you'll see that cobertura easily reports 100% line
