.inferNullableSchema(
  recordName, open(samplePaths.get(0)), props, required)
.toString(!minimize);

@Test

   stream, new CSVProperties.Builder().hasHeader().build());
 Assert.assertEquals("Should use name", "TestRecord", schema.getName());
 Assert.assertEquals("Should set namespace",
   "com.example", schema.getNamespace());
}

@Test

 InputStream stream = new ByteArrayInputStream(csvLines.getBytes("utf8"));
 Schema schema = CSVUtil.inferNullableSchema("TestRecord", stream,
   new CSVProperties.Builder().hasHeader().build(),
   ImmutableSet.of("float"));

@Test
