strongduanmu opened a new issue #10918:
URL: https://github.com/apache/shardingsphere/issues/10918
Hi community,
This issue is for #10887.
# Background
Currently `FederateStatementTest` and `FederatePrepareStatementTest` use
JUNIT to test SQL statements. In order to improve test coverage and code
elegance, we need to migrate the test scenarios of FederateStatementTest and
FederatePrepareStatementTest to `shardingsphere-integration-test`.
# Target
The goal of this issue is to migrate the
`SELECT_SQL_BY_ID_ACROSS_SINGLE_TABLES_WITH_ENCRYPT` statement to the
`shardingsphere-integration-test` module.
You can search for the `SELECT_SQL_BY_ID_ACROSS_SINGLE_TABLES_WITH_ENCRYPT`
keyword, and then you will find the test cases in `FederateStatementTest` and
`FederatePrepareStatementTest`.
FederateStatementTest:
```java
private static final String
SELECT_SQL_BY_ID_ACROSS_SINGLE_TABLES_WITH_ENCRYPT =
"select t_user_encrypt_federate.user_id,
t_user_encrypt_federate.pwd, t_user_info.information from
t_user_encrypt_federate, t_user_info "
+ "where t_user_encrypt_federate.user_id = t_user_info.user_id ";
@Test
public void
assertQueryWithFederateInSingleTablesWithEncryptRuleByExecuteQuery() throws
SQLException {
assertQueryWithFederateInSingleTablesWithEncryptRule(true);
}
@Test
public void
assertQueryWithFederateInSingleTablesWithEncryptRuleByExecute() throws
SQLException {
assertQueryWithFederateInSingleTablesWithEncryptRule(false);
}
private void assertQueryWithFederateInSingleTablesWithEncryptRule(final
boolean executeQuery) throws SQLException {
ShardingSphereStatement statement = (ShardingSphereStatement)
getShardingSphereDataSource().getConnection().createStatement();
ResultSet resultSet = getResultSet(statement,
SELECT_SQL_BY_ID_ACROSS_SINGLE_TABLES_WITH_ENCRYPT, executeQuery);
assertNotNull(resultSet);
assertTrue(resultSet.next());
assertThat(resultSet.getInt(1), is(0));
assertThat(resultSet.getString(2), is("decryptValue"));
assertThat(resultSet.getString(3), is("description0"));
assertTrue(resultSet.next());
assertThat(resultSet.getInt(1), is(1));
assertThat(resultSet.getString(2), is("decryptValue"));
assertThat(resultSet.getString(3), is("description1"));
assertTrue(resultSet.next());
assertThat(resultSet.getInt(1), is(2));
assertThat(resultSet.getString(2), is("decryptValue"));
assertThat(resultSet.getString(3), is("description2"));
assertTrue(resultSet.next());
assertThat(resultSet.getInt(1), is(3));
assertThat(resultSet.getString(2), is("decryptValue"));
assertThat(resultSet.getString(3), is("description3"));
assertFalse(resultSet.next());
}
```
FederatePrepareStatementTest:
```java
private static final String
SELECT_SQL_BY_ID_ACROSS_SINGLE_TABLES_WITH_ENCRYPT =
"select t_user_encrypt_federate.user_id,
t_user_encrypt_federate.pwd, t_user_info.information from
t_user_encrypt_federate, t_user_info "
+ "where t_user_encrypt_federate.user_id =
t_user_info.user_id and t_user_encrypt_federate.user_id > ? ";
@Test
public void
assertQueryWithFederateInSingleTablesWithEncryptRuleByExecuteQuery() throws
SQLException {
assertQueryWithFederateInSingleTablesWithEncryptRule(true);
}
@Test
public void
assertQueryWithFederateInSingleTablesWithEncryptRuleByExecute() throws
SQLException {
assertQueryWithFederateInSingleTablesWithEncryptRule(false);
}
private void assertQueryWithFederateInSingleTablesWithEncryptRule(final
boolean executeQuery) throws SQLException {
ShardingSpherePreparedStatement preparedStatement =
(ShardingSpherePreparedStatement) getShardingSphereDataSource()
.getConnection().prepareStatement(SELECT_SQL_BY_ID_ACROSS_SINGLE_TABLES_WITH_ENCRYPT);
preparedStatement.setInt(1, 1);
ResultSet resultSet = getResultSet(preparedStatement, executeQuery);
assertNotNull(resultSet);
assertTrue(resultSet.next());
assertThat(resultSet.getInt(1), is(2));
assertThat(resultSet.getString(2), is("decryptValue"));
assertThat(resultSet.getString(3), is("description2"));
assertTrue(resultSet.next());
assertThat(resultSet.getInt(1), is(3));
assertThat(resultSet.getString(2), is("decryptValue"));
assertThat(resultSet.getString(3), is("description3"));
assertFalse(resultSet.next());
}
```
# How to
In order to finish this task, you need to understand the
[documentation](https://shardingsphere.apache.org/document/current/en/features/test-engine/integration-test/)
of the integration test first, and PR #10913 also provides an example, which
you can refer to. BTW, if you have any questions, please leave a comment.
