title: Annotator Test
---

In this test we will check if the annotator, implemented in the
[Annotator](annotator.html) section
of the
[Custom Language Support Tutorial](cls_tutorial.html)
works as we expect.

### 1. Define test data

Create a file *AnnotatorTestData.java*.

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

### 2. Define a test method

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

### 3. Run the test

Run the test and make sure it's green.
