I cannot get this this script to produce six results and i need $3$ test cases. Maybe i JUnit isnt setup correctly or something.

package gradecalculater; public class GradeCalculator $\{$f public String calculateGrade$($int$[]$ marks$)\{$ float total $=0$; for $($int mark : marks$)\{$ total $+=$ mark; $\}$ float avg $=$ total $/$ marks.length; if $($avg $>=80)\{$ return $"$A$"$; $\}$ else if $($avg $>=60$ && avg $<mtext></mtext><mn>8</mn><mn>0</mn><mi>)</mi><mtext></mtext><mi>\{</mi>$ return $"$B$"$; $\}$ else if $($avg $>=40$ && avg $<mtext></mtext><mn>6</mn><mn>0</mn><mi>)</mi><mtext></mtext><mi>\{</mi>$ return $"$C$"$; $\}$ else $\{$ return $"$D$"$; $\}\}\}$
