Your targetTests section does not look correct. It accepts globs against fully qualified class names in the same fashion as targetClasses.

But i have tests written with package name RepresentationSystem and it is not something like com.project.example.Test i can attach the picture of my target tests below 

package RepresentationSystem;

import com.company.unitsystem.CultureInfoDefault;
import com.company.unitsystem.RepresentationSystem.*;
import com.company.unitsystem.generated.RepresentationSystem;
import org.junit.Before;
import org.junit.Test;

Here is My second Test package looks like 

package UnitSystem;

import com.company.unitsystem.UnitSystem.CompositeConversionFactor;
import com.company.unitsystem.generated.UnitSystem;
import org.junit.Before;
import org.junit.Test;

You will need to add a wildcard so the classes within the package are picked up.

eg

UnitSystem.*

RepresentationSystem.*

From the output you posted pit looks to be picking up 12 tests. It's hard to say what's going on without more information, but one simple possibility is that none of those tests exercise the mutants that put is creating.

What do the tests and code look like?

[soma srikanth]

It's my bad the code base is written in groovy i think pit works only for java language right ?

Pit won't mutate groovy code, but it has no problem with tests written in groovy.

Gotcha, Thanks for the help :)
