@Test public void testFindEndOfSchemaDeclaration() { String normal = "public static final org.apache.avro.Schema SCHEMA$ = whatever(\"{json}\"); fluff"; String huge = "public static final org.apache.avro.Schema SCHEMA$ = whatever(new StringBuilder().append(\"{json}\").append(\"{more json}\").toString());"; Assert.assertEquals(CodeTransformations.findEndOfSchemaDeclaration(normal), normal.length() - 6); Assert.assertEquals(CodeTransformations.findEndOfSchemaDeclaration(huge), huge.length()); }
