They do a pretty cool thing: force you to tell “the truth” — no matter how subjective this term is — as opposed to emasculated official style: what you really did (whatever it means to you); what opensource/published projects did you participate in; Top Stack questions you answered; your professional reading and (sic!) writing. Here [...]
I don’t like GMock. It’s not as if it was badly written or designed. But it lets you to unit-test dirtier code, tying to method call structure instead of resulting data. For instance, this GMock code can be rewritten:
I wonder why this was not in JDK/Groovy Collections. Just put together a Comparator for StackOverflow question – a Groovy Comparator that would sort class field names in the declaration order. Feel free to use: class PropComparator implements Comparator { private Class clazz PropComparator(Class clazz) { this.clazz = clazz } int compare(Object o1, Object o2) [...]
It hasn’t even been a ten years that DB2, one of the most, er, expensive DBMSes, got a feature needed by every other application – dataset paging. Before, you had to use window functions rownumber() and fetch first 40 rows only. When used by Hibernate, this resulted ugliness like: select * from ( select inner2_.*, [...]
Just installed a shiny new Google Buzz button for WordPress by Tejaswini, Sanjeev. I hacked it a bit, to align to the right. Download this plugin version here, until author updates it. I’m replacing a diggIt button; Buzz fits my color scheme better Enjoy.
Just in case someone needs a code snippet. This one groups Prices by PriceProvider and was intended to pick only last 5 values for each PriceProvider – but sadly, it’s impossible without window functions. Which are not supported in Hibernate in any way.
Hibernate bug 1895 seems to be still there since 2006. If, for instance, in Grails, such a syntax won’t work for you (it won’t): def books = Book.findAll(“FROM Book AS b JOIN Chapter AS c WHERE c.active = :isActive”) with a NullPointerException in “HqlSqlWalker.createFromJoinElement” — just use alternative join syntax, via WHERE: def books = [...]
A friend asked me for it, so probably someone might need a jumpstart in unit tests. Here’s a short list of short (though very deep, if not best) intros. Except for JUnit cookbook (~2 pages) (which has a lot of “ports”, like CppUnit cookbook), I’d name: “Endo-Testing: Unit Testing with Mock Objects” at mockobjects.com (Tim [...]
