datasource-assert provides assertion API for DataSource to validate query executions.
The assertion API is used for assertion methods such as assertEquals in JUnit and TestNG.
Also, it comes with support for assertThat in AssertJ and Hamcrest.

Wrap your datasource with ProxyTestDataSource.
@Test public void myTest() { ProxyTestDataSource ds = new ProxyTestDataSource(actualDataSource); // rest of test }
If you want to reuse the same ProxyTestDataSource instance, you could reset() it between tests.
@After // @AfterEach, @AfterMethod public void tearDown() { this.ds.reset(); }
For normal assertions such as JUnit/TestNG assertEquals, use methods from ProxyTestDataSource.
assertEquals(3, ds.getQueryExecutions().size()); PreparedExecution pe = ds.getFirstPrepared(); assertTrue(pe.isSuccess());
See more details on "Usage examples".
Static import assertThat from DataSourceAssertAssertions.
import static net.ttddyy.dsproxy.asserts.assertj.DataSourceAssertAssertions.assertThat;
assertThat(ds.getQueryExecutions()).hasSize(1); assertThat(ds.getQueryExecutions().get(0)).isStatement().asStatement().query().isEqualTo("SELECT id FROM emp"); assertThat(ds.getFirstPrepared()).containsParam(1, "foo");
See more details on "Usage examples".
Use matchers from DataSourceAssertMatchers.
assertThat(ds, statementCount(3)); assertThat(ds, executions(1, is(statement()))); assertThat((StatementExecution) statements.get(0), query(is("SELECT id FROM emp"))); assertThat(ds.getFirstPrepared(), paramAsInteger(1, is(100)));
