After looking for everywhere a solution, I found that the latest version of PIT only works with Junit5. So, I solved it by migrating to JUnit5

if you are using maven, add the following lines to your pom file:

<properties>
        <junit.jupiter.version>5.8.1</junit.jupiter.version>
        <junit.platform.version>1.8.1</junit.platform.version>
      </properties>
      
      <dependencies>
        <dependency>
            <groupId>org.junit.jupiter</groupId>
            <artifactId>junit-jupiter-engine</artifactId>
            <version>${junit.jupiter.version}</version>
            <scope>test</scope>
        </dependency>
        <dependency>
            <groupId>org.junit.jupiter</groupId>
            <artifactId>junit-jupiter-api</artifactId>
            <version>${junit.jupiter.version}</version>
            <scope>test</scope>
        </dependency>
        <dependency>
            <groupId>org.junit.jupiter</groupId>
            <artifactId>junit-jupiter-params</artifactId>
            <version>${junit.jupiter.version}</version>
            <scope>test</scope>
        </dependency>
        <dependency>
            <groupId>org.junit.platform</groupId>
            <artifactId>junit-platform-suite</artifactId>
            <version>${junit.platform.version}</version>
            <scope>test</scope>
        </dependency>

    </dependencies>
