Create the test file
ReferenceTestData.java in the
testData directory. This file has one Simple Language prefix and key, with the caret placed after the key.

testReference() method to the
SimpleCodeInsightTest class previously defined. This test is configured by the test files. The fixture gets the
PsiReference at the caret position, and then asserts the resolved
SimpleProperty.value() with the known value of that key.
