Arquillian - Weld SE - getting NullPointerException - cdi

Question

I am new to Arquillian and want to get some basic testing working (inject a bean and assert it does something).
Exception:
-------------------------------------------------------------------------------

When I run this, I get a NullPointerException, the bean manager is null. It looks like I am missing a step, but from the examples, it looks like this is all I should need.
Any ideas?

Answer 1

It looks to me like are trying to use the latest snapshot. Currently the Arquillian repository is being restructured, so unless you have a specific reason for tracking HEAD, I recommend using Alpha5.
You can see working CDI examples in the Arquillian showcase. http://github.com/arquillian/arquillian-showcase

Answer 2

I had a similar problem with arquillian 1.0.4.Final. Getting "java.lang.RuntimeException: Could not inject members" plus stacktrace. This on tests running since a year. The JUnit tests worked if calling the test classes one by one, but failed if calling all test either by doing a Junit test of the whole module, or doing a maven site test of the whole project. No matter to solve the problem, but resetting the arquillian version back to 1.0.3.Final!
