在 docker 容器内运行 maven 集成测试

Question

I am using dockerfile-maven plugin to move my jar file inside docker container before running integration testing. But mvn verify command builds the images and run integration test, as a result test fails. Can someone help me run the docker images before running integration test. So that I can ping to service running inside docker container from my integration test file.

Below is my integration test file.

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.Statement;
import java.sql.SQLException;
import java.sql.ResultSet;
import java.io.IOException;
import java.io.File;
import java.util.Scanner;
import static org.hamcrest.MatcherAssert.*;
import static org.junit.matchers.JUnitMatchers.*;
import org.junit.Assert.*;
import com.facebook.presto.jdbc.PrestoDriver;
import io.airlift.log.Logger;
import org.testng.annotations.Test;

class IntegrationTestIT {

@Test
public void checkForQueryInFile() {

    System.out.println("This test method should be run");
    String url = "jdbc:presto://localhost:8889/jmx/default";

    Statement stmt = null;
    try {
        Connection connection = DriverManager.getConnection(url, "jumbo", null);

        stmt = connection.createStatement();
        String file_path = "";
        String sql_string = "show schemas";

        ResultSet rs = stmt.executeQuery(sql_string);
        File folder = new File("//jars");
        // Move this to constant class
        File[] files = folder.listFiles(); 

        for (File file:files) {
            if (file.isFile()) {
                file_path = file.getAbsolutePath();
            }
        }
        File log_file = new File(file_path);
        final String scanner = new Scanner(log_file).useDelimiter("\\Z").next();;

        assertThat(scanner, containsString(sql_string));

    rs.close();
    stmt.close();
    connection.close();

    } catch (IOException exception) {
        exception.printStackTrace();
    } catch(SQLException sqlException) {
        sqlException.printStackTrace();
    }
}
}

Answer 1

Accessibility error message :

java.lang.IllegalAccessException: Class org.testng.internal.MethodInvocationHelper can not access a member of class IntegrationTestIT with modifiers "public"

You have to make your class public to run tests :

public class IntegrationTestIT {
...

Sequencing issue :

If your integration tests are running in the integration-test phase, you can force the execution of the docker plugin during the pre-integration-test phase :

<execution>
    ...
    <phase>pre-integration-test</phase>
</execution>
