Java fork

• upgrade to JUnit 5
• fixes this issue
• adding assertion messages
• fixes actual and expected being flipped in sample tests
• mark reference solution as private

python new test framework is required. updated in this fork

Error! Illegal number found in row!

Test error feedback is unacceptable. It should at least tell where exactly is wrong.

Sample tests are broken.

Ruby should be updated to new test framework

The CS version generates n in floating point numbers which is irrelevant to the task !!! This makes a correct solution unable to pass the random tests ~~

In python initial solution should have 4-space indentation and no final ;.

Palindromization - Java 1.8.0_91(Java 8)
I have problem with the exercise. When I run the sample test without modifying the code I get following error message.
STDERR:
/workspace/java/src/KataTests.java:28: error: class, interface, or enum expected
}
^
1 error

I noticed that there is addition closing curly brace (}) with no opening brace.

Default code

public class Kata {
public static String palindromization(String elements, int n) {
return elements;
}
}

Sample Test

import org.junit.Test;
import static org.junit.Assert.assertEquals;
import org.junit.runners.JUnit4;
public class KataTests {
@Test
public void Error_Cases() {

    assertEquals(Kata.palindromization("", 2), "Error!");
    assertEquals(Kata.palindromization("123", 1), "Error!");

}

@Test
public void Examples() {
    
    assertEquals(Kata.palindromization("123", 2), "11");
    assertEquals(Kata.palindromization("123", 3), "121");
    assertEquals(Kata.palindromization("123", 4), "1221");
    assertEquals(Kata.palindromization("123", 5), "12321");
    assertEquals(Kata.palindromization("123", 6), "123321");
    assertEquals(Kata.palindromization("123", 7), "1231321");
    assertEquals(Kata.palindromization("123", 8), "12311321");
    assertEquals(Kata.palindromization("123", 9), "123121321");
    assertEquals(Kata.palindromization("123", 10), "1231221321");
    
}

} // No opening curly brace
}
