My test doesn't output in console I'm using Maven

I'm new to Maven and Im facing this kind of of weird stuff Im using Intellij.
class HelloWorldTest {
public void testHello() {
System.out.println("Test - hello! ");
}
public void testWorld() {
System.out.println("Test - World!");
}
}
When I run package on Default Lifecycle It show's output below Test run: 0. The test isn't running and output in console. I'm Following tutorial Apache Maven Beginner to Guru on udemy.

You need to annotate your test class with #Test. And you should consult the JUnit manual

Maven Surefire not running JUnit 5 tests

I've been trying to run JUnit 5 tests with Maven Surefire. However, it doesn't seem like Surefire is running any tests at all, even though I do have some, and in the default directory, too.
This is the console output I'm getting: https://prnt.sc/ugo1xt
Here are the relevant parts of the pom.xml:
<dependencies>
<dependency>
<groupId>org.junit.jupiter</groupId>
<artifactId>junit-jupiter</artifactId>
<version>5.7.0-M1</version>
<scope>test</scope>
</dependency>
</dependencies>
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>${maven-surefire-plugin.version}</version>
</plugin>
</plugins>
</build>
The surefire version is 3.0.0-M4.
I've tried pretty much any fix I could find on Google, although most of them seemed to be outdated. Any help would be greatly appreciated.
Cheers!
EDIT: Here's an example of my tests:
package bankprojekt;
import bankprojekt.verarbeitung.*;
import org.junit.jupiter.api.*;
import static org.junit.jupiter.api.Assertions.*;
public class GirokontoTest {
Girokonto gk;
#BeforeEach
void setup(){
gk = new Girokonto();
gk.einzahlen(500);
}
#AfterEach
void teardown(){
gk = null;
}
#Test
void abhebenMitWaehrungswechsel(){
try{
gk.abheben(195.583, Waehrung.BGN);
}
catch (Exception e) {
System.out.println(e);
}
assertEquals(400, gk.getKontostand());
}
#Test
void einzahlenMitWaehrungswechsel(){
gk.einzahlen(195.583, Waehrung.BGN);
assertEquals(600, gk.getKontostand());
}
}

There are two things. First you should upgrade jacoco dependency to 0.8.5 otherwise it fails based on the JDK14 requirement. (Created an pull request to your repository). If those things are configured appropriately the result is this:
I would also recommend to upgrade maven-compiler-plugin to most recent version and also all other plugins.
As you can see you have WARNING's in your build which should be fixed and failing tests.
This build has been run on plain command line also with JUnit-Jupiter 5.7.0 which works perfectly.

Testing a single package skips parametrized tests in TestNG

Overall description
I have a simple Maven project with a parameterized TestNG test. The parameter is specified through a suite XML file. When I run tests for the whole project, the suite XML file is read, parameter is used and the parameterized test is executed. However, when I attempt to test a single package only, then the suite XML file is not used apparently and the test is skipped with a complaint such as "Parameter '...' is required by #Test on method ... but has not been marked #Optional or defined". The question is how to run individual tests and test packages with parameters.
For more details see below.
Testing the whole project
This works as expected. Two test methods are executed. One test method is parameterless, other is parameterized and the parameter value is taken from the suite XML file. This is a equivalent of Run\Test project in NetBeans.

You need separate XML files for separate package. When running TestNG with package as parameter, TestNG is not automatically aware about the XML file, like it doesn't exist.
So you have multiple options, specify the parameters in properties file, or hardcode them, or create separate XML files for every package that you can then pass as parameter.

How to prevent building if integration test was failed?

I've got the following test:
public class AppITCase
{
#Test
public void failTest() {
fail();
}
}
It just fails. But if I run mvn clean test-compile failsafe:integration-test, I will see this:

Whats wrong here?

Update 05/10/2015: As of now version 2.7 (apparently) supports this - thanks #tomasz_kusmierczyk
Looks like this is because Cobertura 2.0.3 depends on ASM 4.1, which doesn't support Java 8. I managed to "fix" this by forcing cobertura-maven-plugin to use ASM 5.0.3, but I'm not completely sure that this is the correct way of doing things. It did however get rid of all of those warnings.
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>cobertura-maven-plugin</artifactId>
<version>2.6</version>
...
<dependencies>
<dependency>
<groupId>org.ow2.asm</groupId>
<artifactId>asm</artifactId>
<version>5.0.3</version>
</dependency>
</dependencies>
</plugin>
The right way to go is probably to use a different code coverage tool, like JaCoCo which is meant to have support for Java 8.
Update: Looks like you lose some code coverage info if you go down this route, and so another CC tool is indeed the way to go.

From https://github.com/cobertura/cobertura/wiki/FAQ#classnotfoundexception-during-instrumentation:
"This is because during instrumentation in cobertura 2.0, we use ASM to rebuild the .class files. We rebuild the stackmap which is a requirement to be compatible with java 7 and anything after. This does not mean that we recompile the code, however ASM requires that we provide the binaries of the other classes just in case it needs to look up any super methods. To fix this we use an argument called auxClasspath."
Adding the following code to your ant file (build.xml) should resolve the issue.
<path id="cobertura.auxpath">
<pathelement location="${bin}"/>
</path>
<target name="instrument_coverage" depends="init_coverage"
description="Instruments source code for coverage measurement">
<cobertura-instrument datafile="${coverage.datafile}">
<fileset refid="coverage-files"/>
<auxClasspath>
<path refid="cobertura.auxpath" />
</auxClasspath>
</cobertura-instrument>
</target>
This worked for me.
