Mocking static methods with Mockito

Question

I've written a factory to produce java.sql.Connection objects:

public class MySQLDatabaseConnectionFactory implements DatabaseConnectionFactory {

    @Override public Connection getConnection() {
        try {
            return DriverManager.getConnection(...);
        } catch (SQLException e) {
            throw new RuntimeException(e);
        }
    }
}

I want to validate the parameters passed to DriverManager.getConnection, but I have no idea about how to mock a static method. Is there a good way to mock/verify this specific use-case?

Answer 1

@RunWith(PowerMockRunner.class)
@PrepareForTest(DriverManager.class)
public class Mocker {

    @Test
    public void testName() throws Exception {

        //given
        PowerMockito.mockStatic(DriverManager.class);
        BDDMockito.given(DriverManager.getConnection(...)).willReturn(...);

        //when
        sut.execute();

        //then
        PowerMockito.verifyStatic();
        DriverManager.getConnection(...);

    }
