The simple explanation would be that the standard requires assert to be a macro, if we look at the draft C99 standard(as far as I can tell the sections are the same in draft C11 standard as well) section 7.2 Diagnostics paragraph 2 says: The assert macro shall be implemented as a macro, not as … Read more
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__ \ << ” line ” << __LINE__ … Read more
To be specific: Go to Run->run configuration select java application in left nav pan. right click and select New. select Arguments tab Add -ea in VM arguments.
It’s important to remember that PEP8 is only a guideline and even states that there are times when the rules should be broken. But most importantly: know when to be inconsistent — sometimes the style guide just doesn’t apply. With that in mind, I would probably write this with old style line continuation: def afunc(some_param_name): … Read more
Are there any advantages to having assert be a statement (and reserved word) instead of a function? Cannot be reassigned to a user function, meaning it can be effectively disabled at compile time as @mgilson pointed out. The evaluation of the second, optional parameter is deferred until if/when the assertion fails. Awkward to do that … Read more
Use the case construct: select ‘Test Name’, case when foo = ‘Result’ then 1 else 0 end from bar where baz = (some criteria) Also see the MSDN Transact-SQL CASE documentation.
You ask three questions, so I will try to answer each of them. Can someone give me an example of where only static_assert will work, or only assert? static_assert is good for testing logic in your code at compilation time. assert is good for checking a case during run-time that you expect should always have … Read more
The official junit solution to assert that two BigDecimal are matematically equal is to use hamcrest. With java-hamcrest 2.0.0.0 we can use this syntax: // import static org.hamcrest.MatcherAssert.assertThat; // import org.hamcrest.Matchers; BigDecimal a = new BigDecimal(“100”) BigDecimal b = new BigDecimal(“100.00”) assertThat(a, Matchers.comparesEqualTo(b)); Hamcrest 1.3 Quick Reference
Python 3 If you don’t care about the order of the content, you have the assertCountEqual(a,b) method If you care about the order of the content, you have the assertSequenceEqual(a,b) method Python >= 2.7 If you don’t care about the order of the content, you have the assertItemsEqual(a,b) method If you care about the order … Read more
Use assertions for internal logic checks within your code, and normal exceptions for error conditions outside your immediate code’s control. Don’t forget that assertions can be turned on and off – if you care about things like argument validation, that should be explicit using exceptions. (You could, however, choose to perform argument validation on private … Read more
