Docker Example project

[rushey1]

In the docker example there is a standard java project which didn't help me follow the example.

Can you please provide a simple java class to follow? For example, assume we have the following Triangle class in Triangle/src/main/java/org/triangleValidator folder. How can I use docker to fuzz this class for 2 minutes and start with sample inputs in /corpus/corpusinput.txt and place produced results in /corpus folder?

package org.triangleValidator; import java.util.Scanner;

public class Triangle { public static boolean isValidTriangle(int side1, int side2, int side3) { // Check if the sum of any two sides is greater than the third side return (side1 + side2 > side3) && (side1 + side3 > side2) && (side2 + side3 > side1); } public static void main(String[] args) { Scanner scanner = new Scanner(System.in);

    System.out.println("Enter the lengths of 3 sides:");
    int side1 = scanner.nextInt();
    int side2 = scanner.nextInt();
    int side3 = scanner.nextInt();

    if (isValidTriangle(side1, side2, side3)) {
        System.out.println("Valid triangle!");
    } else {
        System.out.println("Not a valid triangle!");
    }
}

}

Thank you

The docker image is a helpful starting point if you don't want or can't install Jazzer locally.

If you're starting out with Jazzer and struggle with general Docker usage, I suggest to use a locally installed Jazzer version (see GitHub releases), as that reduces complexity considerably.

Regardless of how you invoke Jazzer, you need to write a fuzz target (fuzzerTestOneInput method, e.g. this example, or JUnit 5 test function, e.g. this example project), compile everything and put it on the Java classpath when starting Jazzer.
