using ShadowTest = aura::test::AuraTestBase?

Done.

Can you comment on what this is expecting/testing?

[Evan Stade, 2016/12/06 00:53:21]

beyond the comments that already exist, what details would you recommend adding?

[James Cook, 2016/12/06 18:17:51]

Actually, this is fine.

[James Cook, 2016/12/05 23:38:35]

nit: Either use a new variable, or split the test into two tests. I've been
burned by recycling variables in tests many times. :-)

[Evan Stade, 2016/12/06 00:53:21]

Done.

Nice. The linker thanks you.
