com.google.javascript.rhino.testing.TestErrorReporter
An error reporter for testing that verifies that messages reported to the reporter are expected.

Sample use
```
 TestErrorReporter e = new TestErrorReporter(null, new String[] { "first warning" }); ... assertTrue(e.hasEncounteredAllWarnings()); 
```

    Node node2 = new Node(Token.INC);
    assertNotNull(node1.checkTreeEqualsImpl(node2));
  }


  public void testCheckTreeTypeAwareEqualsSame() {
    TestErrorReporter testErrorReporter = new TestErrorReporter(null, null);
    JSTypeRegistry registry = new JSTypeRegistry(testErrorReporter);
    Node node1 = Node.newString(Token.NAME, "f");
    node1.setJSType(registry.getNativeType(JSTypeNative.NUMBER_TYPE));
    Node node2 = Node.newString(Token.NAME, "f");
    node2.setJSType(registry.getNativeType(JSTypeNative.NUMBER_TYPE));
