Review Comment:
I would probably slightly change this to something like:
```
@Test
public void schemaIsMigratedToAddViewSupport() throws Exception {
// as this test uses different connection, we can't use memory database
(as it's per
// connection), but a
// file database instead
java.nio.file.Path dbFile = Files.createTempFile("icebergSchemaUpdate",
"db");
String jdbcUrl = "jdbc:sqlite:" + dbFile.toAbsolutePath();
initLegacySchema(jdbcUrl);
Map<String, String> properties = Maps.newHashMap();
properties.put(CatalogProperties.WAREHOUSE_LOCATION,
this.tableDir.toAbsolutePath().toString());
properties.put(CatalogProperties.URI, jdbcUrl);
properties.put(JdbcUtil.ADD_VIEW_SUPPORT_PROPERTY, "true");
JdbcCatalog jdbcCatalog = new JdbcCatalog();
jdbcCatalog.setConf(conf);
jdbcCatalog.initialize("TEST", properties);
TableIdentifier tableOne = TableIdentifier.of("namespace1", "table1");
TableIdentifier tableTwo = TableIdentifier.of("namespace2", "table2");
assertThat(jdbcCatalog.listTables(Namespace.of("namespace1")))
.hasSize(1)
.containsExactly(tableOne);
assertThat(jdbcCatalog.listTables(Namespace.of("namespace2")))
.hasSize(1)
.containsExactly(tableTwo);
assertThat(jdbcCatalog.listViews(Namespace.of("namespace1"))).isEmpty();
TableIdentifier view = TableIdentifier.of("namespace1", "view");
jdbcCatalog
.buildView(view)
.withQuery("spark", "select * from tbl")
.withSchema(SCHEMA)
.withDefaultNamespace(Namespace.of("namespace1"))
.create();
assertThat(jdbcCatalog.listViews(Namespace.of("namespace1"))).hasSize(1).containsExactly(view);
}
```
