4. Annotator Test

This test checks if the Simple Language annotator functionality, implemented in the Annotator section of the Custom Language Support Tutorial, works as expected.

Define Input Test Data

The DefaultTestData.simple file is reused for this test.

Create an input test file AnnotatorTestData.java in the testData directory. This file contains two instances of Simple Language embedded in the Java code. The first instance is a valid use of the simple: prefix followed by the Simple Language key website. The second is a valid prefix but an invalid key websit, as noted by the test <error> highlighting.

public class Test {
  public static void main(String[] args) {
    System.out.println("simple:website");
    System.out.println("simple:<error descr="Unresolved property">websit</error>");
  }
}

Define a Test Method

Add the testAnnotator() method to the SimpleCodeInsightTest class previously defined. Again, this method configures the test fixture by using the test files. It then calls the checkHighlighting() method to verify weak warnings.

  public void testAnnotator() {
    myFixture.configureByFiles("AnnotatorTestData.java", "DefaultTestData.simple");
    myFixture.checkHighlighting(false, false, true, true);
  }

Run the Test

Run the test and make sure it's green.
