+In this test we will check if the folding builder, implemented in the
+[Folding Builder](folding_builder.html)
+section of the
+[Custom Language Support Tutorial](cls_tutorial.html),
+works as we expect.
+
+### 1. Define test data
+
+Create a file *FoldingTestData.java*.
+
+```java
+public class Test {
+    public static void main(String[] args) <fold text='{...}'>{
+        System.out.println("<fold text='http://en.wikipedia.org/'>simple:website</fold>");
+    }</fold>
+}
+```
+
+### 2. Define a test
+
+```java
+public void testFolding() {
+    myFixture.configureByFiles("DefaultTestData.simple");
+    myFixture.testFolding(getTestDataPath() + "/FoldingTestData.java");
+}
+```
+
+### 3. Run the test
+
+Run the test and make sure it's green.
