My JUnit tests don't work when I execute them via maven

I use Maven on my test project and I wanted to test test option in Maven's lifecycle, but my JUnit test failed. I have a class named Arithmetics in src.main.java package and a class named ArithmeticsTest in src.test.java package.
When I run ArithmeticsTest on my own using IntelliJ IDEA everything works OK, and I have expected java.lang.AssertionError, so why I don't have such when I run test option in maven?
Console output:
T E S T S
Results :
Tests run: 0, Failures: 0, Errors: 0, Skipped: 0
src.main.java.Arithmetics.java
public class Arithmetics
{
public static int add(int a, int b)
{
return a + b;
}
}

import static org.junit.jupiter.api.Assertions.*;
public class ArithmeticsTest
{
#Test
public void testAdd()
{
assertEquals(4, Arithmetics.add(2, 3));
}

There are three wrong things I can spot based on your question, while they might not provide a complete answer I hope they'll will be a step in a right direction:
src/main/java and src/test/java is not a package as you write. Its a folder layout supported by maven, basically , if you have a code in com.myorg.somepackage.Arithmetics
Make sure you have the following layout at the level of actual physical folders:
src
main
java
com
myorg
somepackage
Arithmetics.java
test
java
com
myorg
somepackage
ArithmeticsTest.java
For both java files the package must be com.myorg.somepackage:
package com.myorg.somepackage;
public class Arithmetics {}
And
package com.myorg.somepackage;
public class ArithmeticsTest {}
I know it might be a wrong naming that you've used in the question, but still I have to state it because it might cause an actual issue
The second issue is that for some reason you seem to configure your surefire plugin to use test ng which is an alternative to junit. It can happen because testng is placed as a dependency - I can only speculate because you don't really show the full surefire plugin configure and do not provide a full list of dependencies, but you've got and idea I believe :)
This is wrong because you use the junit5 dependencies as well as the imports that correspond to the junit 5.
The dependencies on the junit 5 are completely messy:
You seem to have two dependencies on just the same with the different scope, its really a wrong thing to do. Make sure you use only the test scope and have all the relevant dependencies. Read here for instruction of how to configure the surefire plugin
In addition, for the sake of completeness of the answer, check that you use the recent version of surefire plugin, if its too old the chances are that it won't be able to run jupiter engine (junit 5)

As other answer already pointed out few things which may go wrong in your case, I am just adding the solution to your pom xml.
The surefire plugin version is the main culprit. Default with maven (2.12.4) will not work with junit-5 jupiter engine.
So just add the plugin in your with version 2.22.1 in your pom, it should work after that, assuming your folder structure as per required (see other answer).
<build>
<pluginManagement>
<plugins>
<plugin>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.22.1</version>

Unable to control parallel execution for cucumber

I am unable to control the treads from dataproviderthreadcount.
For example if we have 4 scenario and I run my script, it execute all 4 scenario's parallelly. Doesn't matter what dataproviderthreadcount value I gave in the pom for maven-surfire.
Below are the snapshots.

Please let me if anyone know how to control the number of threads rather than let Testng decide.

There's no problem with TestNG per se here.
The dataproviderthreadcount attribute that you have set in your pom file is going to be applicable and relevant only when you are running your test via mvn clean test.
If you are trying to run this test class from within the IDE (IntelliJ or Eclipse for that matter) its not going take affect.
Here's a test class that I created which is powered by a data provider ( For the sake of simplicity I have intentionally kept cucumber out of the equation )
import org.testng.annotations.DataProvider;
import org.testng.annotations.Test;
public class AppTest {
#Test(dataProvider = "dp")
public void shouldAnswerWithTrue(int i) {
System.err.println("Running on [" + Thread.currentThread().getId() + "]");
}
#DataProvider(name = "dp", parallel = true)
public Object[][] testData() {
return new Object[][]{
{1},
{2},
{3},
{4},
{5},
{6}
};
}
}
Here's the command line output when I run mvn clean test

I encountered the exact same. As Krishnan mentioned, the dataproviderthreadcount in pom.xml works only when you run mvn test but without any parameter. If you want to specify which suite xml to run, you will need to add -Ddataproviderthreadcount=2 in command line as well. For example, "mvn -Dsurefire.suiteXmlFiles=suite.xml -Ddataproviderthreadcount=2 test"

You need to provide the hibernate dialect to configure hibernate befor connecting
use
spring.jpa.database-platform=org.hibernate.dialect.H2Dialect

The error looks like, it can't figure out the dialect to be used with H2.
The dialect specifies the type of database used in hibernate so that hibernate generate appropriate type of SQL statements.
The dialect to be used for h2 is this:
spring.jpa.database-platform=org.hibernate.dialect.H2Dialect
Also being new to programming might confuse you to write optimal code. It looks like, you are mixing up things from older versions of spring boot and spring. Please use,
https://start.spring.io
to generate your initial spring boot project with the required dependencies. You can follow the below tutorial which explains nicely to get started with spring boot and h2.

Not able to configure Spring Boot with Cucumber having more than one step files

I have a Cucumber-Selenium based test written using Spring Boot. The problem is that if I have just one step definition file GoolgeCalcStepDefinition.java then the program works and test passes without any issue but as soon as I added BingSearchStepDefinition.java along with feature file then I get following error.
I googled around on how to configure Spring Boot with Cucumber but most of the examples/articles available online shows only one step definition file.

Both of your runner classes extend DemoApplicationTests.java which is itself a #SpringBootTest.
Cucumber cannot determine which SpringBootContext to load when it fires up.. remove the class extends from your stepdefs and have TestRunner extend DemoApplicationTests instead

Get list of activated profile name during run time in maven java project

I need to be able to use the profile activated during the run time of JUnit tests.
I was wondering if there is any way of doing something like:
String str = System.getProperty("activated.profile[0]");
Or any other relative way...
I realized there is an option to use ${project.profiles[0].id} bu somehow it's not working.
Any ideas?

When using surefire to run the unit tests, it usually spawns a new JVM to run the tests, and we have to pass the information to the new JVM. This can be done usually using the "systemPropertyVariables" tag.
I was able to exercise this using a quickstart Java project, where I added this to the POM:
I declared the following profiles
<profiles>
<profile>
<id>special-profile1</id>
</profile>
<profile>
<id>special-profile2</id>
</profile>
</profiles>
And this to surefire configuration:
<build>
<plugins>
...
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.19</version>
<configuration>
<systemPropertyVariables>
<profileId>${project.activeProfiles[0].id}</profileId>
</systemPropertyVariables>
</configuration>
</plugin>
...
</plugins>
</build>
And in my unit test, I added this:
/**
* Rigourous Test :-)
*/
public void testApp()
{
System.out.println("Profile ID: " + System.getProperty("profileId"));
}
When invoking the "test" command without profile (i.e. using mvn test), I got this:
-------------------------------------------------------
T E S T S
-------------------------------------------------------
Running com.fxs.AppTest
Profile ID: development
Tests run: 1, Failures: 0, Errors: 0, Skipped: 0, Time elapsed: 0.003 sec - in com.fxs.AppTest
Results :
Tests run: 1, Failures: 0, Errors: 0, Skipped: 0
And we I used mvn -P special-profile2 test, I got this
-------------------------------------------------------
T E S T S
-------------------------------------------------------
Running com.fxs.AppTest
Profile ID: special-profile2
Tests run: 1, Failures: 0, Errors: 0, Skipped: 0, Time elapsed: 0.002 sec - in com.fxs.AppTest
Results :
Tests run: 1, Failures: 0, Errors: 0, Skipped: 0
This will pass along the name of the first active profile. If we have potentially more than one active profiles, then we will probably need to use more system properties.
Note: I tested this using Maven 3.1.1

I other cases I used next in pom file:
<profiles>
<profile>
<id>a-profile-id</id>
<properties>
<flag>a-flag-value</flag>
</properties>
</profile>
</profiles>
and in java:
String flagValue = System.getenv("flag");
