[Solved] enum/.../.members access in Test context
Hi,
I try to write a BTestCase where I iterate over an enum's member like so
foreach member in enum/MyEnum/.members {
// test something
}
However, I get the following exception:
java.lang.NullPointerException
at jetbrains.mps.lang.smodel.generator.smodelAdapter.SEnumOperations.getEnum(SEnumOperations.java:19)
I tried to access other operations on my enum/MyEnum/, resulting in the same Exception. I also tried to access an enum in the context of a NodeTestCase, also witht he same exception.
Any advice?
Thanks!

According to some feedback on the Slack channel, SModel components are not initialized in UnitTests which causes the exception.
I am able to test the members of the enum with MPS 2017.1. Can you please pinpoint the problem exactly?
Thanks,

Hi Narendran,
there seems to be a misunderstanding. What I was trying to do was to iterate over the members of a "language enum" (i.e. an Enum you define in the structure aspect) from within a BTestCase. I learned from a discussion in the MPS slack channel that the SModel components are not initialized for such Unit tests.
Like in your example, I can test the members of such an enum in a NodeTest as well. I was basically just not aware that the SModel components are uninitialized when a BTestCase is run. Why it didn't work initially in a NodeTest I could not reproduce.
Best,
Robert
