In a previous article I described how to load test data that your ScalaTest Play Framework functional tests might need using Play Framework’s Evolutions. This made use of the SimpleEvolutionsReader class and defining evolutions in the test setup code. Recently I wanted to also load some test data from a file and so turned to the ClassLoaderEvolutionsReader class which loads resources from the class path. The trouble was I wanted to apply the schema from […]

Making an enum implement an interface can be a useful way to split large enums into smaller classes.

Have you ever noticed misspelled HTTP response headers? $ http -h http://www.dmoz.org/Computers/Programming/Languages/Python/Books/ HTTP/1.1 200 OK Connection: close Content-Encoding: gzip Content-Language: en Content-Length: 9907 Content-Type: text/html;charset=UTF-8 Cteonnt-Length: 33416 Date: Tue, 12 Apr 2016 12:26:06 GMT Server: Apache That ‘Cteonnt-Length’ sure looks weird! According to this StackOverflow answer, the jumbled header contains the uncompressed size of the response and, sure enough, it does seem to be the case. But why? It seems like this is a trick […]

It is common when working with git to use lots of branches. Occasionally you might accidentally commit to the wrong branch but thankfully git makes it easy to put these commits in the right place.

There are […]

The OneAppPerSuite trait will share the same Application instance across all tests in a class whereas the OneAppPerTest trait gives each test its own Application instance. These traits will ensure you have a running application for your tests but if you want to test code that operates on a database […]
