DDevelopment & Design

Friday hackathon

Every month we have a Friday Hackathon, where we can code or create anything we want. That’s for the purpose of evaluating new technologies, doing crazy stuff or just having fun.

Beneath that we develop our skills and gain new experience.

Today we have 5 teams, that are doing following projects in various technologies:

  • Ping-pong scoring – we play ping pong a lot, so an app is a must! – Java (Dropwizard), Mongo
  • TouK’s library – we have dozens of books but currently we have a chaos who lends what – Clojure
  • ToukApi – access all internal data (about people, salaries, holidays, auth, projects people are in etc) through REST api – vert.x
  • ID / Drivers license recognition on Mobile – just shoot a photo of an ID and have all data and photo in a few seconds – Kotlin, Android
  • jaIde – I’m going for a sandwich – you can inform other employees that you go for a morning sandwich – that means – Mr Sandwich has just arrived at the kitchen – it’s like a snowball, the more people go for a sandwich the more confident you can be that there are actually sandwiches waiting :) – Swift/Scala/Java

At 4:30 PM we have hackathon summary. Let’s see what projects we will manage to accomplish…

Grails with Spock unit test + IntelliJ IDEA = No thread-bound request found

During my work with Grails project using Spock test in IntelliJ IDEA I've encountered this error:

java.lang.IllegalStateException: No thread-bound request found: Are you referring to request attributes outside of an actual web request, or processing a request outside of the originally receiving thread? If you are actually operating within a web request and still receive this message, your code is probably running outside of DispatcherServlet/DispatcherPortlet: In this case, use RequestContextListener or RequestContextFilter to expose the current request.
 at org.springframework.web.context.request.RequestContextHolder.currentRequestAttributes(RequestContextHolder.java:131)
 at org.codehaus.groovy.grails.plugins.web.api.CommonWebApi.currentRequestAttributes(CommonWebApi.java:205)
 at org.codehaus.groovy.grails.plugins.web.api.CommonWebApi.getParams(CommonWebApi.java:65)
... // and few more lines of stacktrace ;)

It occurred when I tried to debug one of test from IDEA level. What is interesting, this error does not happen when I'm running all test using grails test-app for instance.

So what was the issue? With little of reading and tip from Tomek Kalkosiński (http://refaktor.blogspot.com/) it turned out that our test was missing @TestFor annotation and adding it solved all problems.

This annotation, according to Grails docs (link), indicates Spock what class is being tested and implicitly creates field with given type in test class. It is somehow strange as problematic test had explicitly and "manually" created field with proper controller type. Maybe there is a problem with mocking servlet requests?
