10. Reference Test

Define Test Data

This test reuses the Simple Language file DefaultTestData.simple.

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.

Define a Test Method

Add the 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.

Run the Test

Run the test and make sure it's green.
