JUnit - Parameterized Test - Stopping compiling - junit

Question

Code that I writed below stopping compliling before contructor or #Before (depend of hiding). There is no errors and It can't run even one time.
I did it with tutorial:
https://www.tutorialspoint.com/junit/junit_parameterized_test.htm
Can somebody have idea what is wrong with this code?
import static org.junit.Assert.*;

#RunWith(Parameterized.class)
public class ParametryzowaneTestyKarty {
private ArrayList<Karta> talia;
private String wynik;
private karty kartyy;
#Before
public void initialize() {
kartyy = new karty();
}
public ParametryzowaneTestyKarty(ArrayList<Karta> talia, String wynik) {
this.talia = talia;
this.wynik = wynik;
}
#Parameterized.Parameters
public static Collection wyniki() throws FileNotFoundException {
File plik22 = new File("...");
Scanner test = new Scanner(plik22);
while(test.hasNextLine()) {
ArrayList<Karta> talia = new ArrayList<>();
String wiersz = test.nextLine();
String[] parts = wiersz.split(",");
for(int i=0;i<10;i+=2) {
String part0 = parts[i];
String part1 = parts[i+1];
int kol=Integer.parseInt(part0);
int fig=Integer.parseInt(part1);
Kolor[] k = Kolor.values();
Kolor ko=k[kol];
Figura[] f = Figura.values();
Figura fi = f[fig];
talia.add(new Karta(ko, fi));
String w = parts[10];
Arrays.asList(new Object[][] {
{ talia, w },
});
}
}
return Arrays.asList();
}
#Test
public void TestParametryzowaneKarty() {
System.out.println("1");
System.out.println("Karty : " + talia);
assertEquals(wynik,
karty.check(talia));
}
}

Answer 1

It would help to know the exact error you are getting.
There are some issues with your code, as Arrays.asList() doesn't do what you are expecting, and as thus the method public static Collection wyniki() is returning a empty list.
The following code might fix the issue, but I doubt it as the talia list is reused for each row in the file that is being read.
#Parameterized.Parameters
public static Collection wyniki() throws FileNotFoundException {
File plik22 = new File("...");
Scanner test = new Scanner(plik22);
while(test.hasNextLine()) {
ArrayList<Karta> talia = new ArrayList<>();
ArrayList<Object[]> rows = new ArrayList<>();
String wiersz = test.nextLine();
String[] parts = wiersz.split(",");
for(int i=0;i<10;i+=2) {
String part0 = parts[i];
String part1 = parts[i+1];
int kol=Integer.parseInt(part0);
int fig=Integer.parseInt(part1);
Kolor[] k = Kolor.values();
Kolor ko=k[kol];
Figura[] f = Figura.values();
Figura fi = f[fig];
talia.add(new Karta(ko, fi));
String w = parts[10];
// new code
rows.add(new Object[]{talia, w} );
}
}
return rows;
}
