对Triangle进行JUnit测试并设计测试用例使其满足100%函数覆盖、语句覆盖和判定覆盖并把Java代码给我

好的，这是Triangle类的Java代码：

public class Triangle {
    private double side1;
    private double side2;
    private double side3;

    public Triangle(double s1, double s2, double s3) {
        side1 = s1;
        side2 = s2;
        side3 = s3;
    }

    public boolean isTriangle() {
        if (side1 <= 0 || side2 <= 0 || side3 <= 0) {
            return false;
        }

        if (side1 + side2 <= side3 || side1 + side3 <= side2 || side2 + side3 <= side1) {
            return false;
        }

        return true;
    }

    public String getType() {
        if (!isTriangle()) {
            return "Not a triangle";
        }

        if (side1 == side2 && side2 == side3) {
            return "Equilateral triangle";
        } else if (side1 == side2 || side1 == side3 || side2 == side3) {
            return "Isosceles triangle";
        } else {
            return "Scalene triangle";
        }
    }
}

下面是满足100%函数覆盖、语句覆盖和判定覆盖的JUnit测试用例：

import org.junit.Test;
import static org.junit.Assert.*;

public class TriangleTest {
    @Test
    public void testIsTriangle() {
        // Test invalid triangles
        Triangle t1 = new Triangle(-1, 2, 3);
        assertFalse(t1.isTriangle());

        Triangle t2 = new Triangle(1, -2, 3);
        assertFalse(t2.isTriangle());

        Triangle t3 = new Triangle(1, 2, -3);
        assertFalse(t3.isTriangle());

        Triangle t4 = new Triangle(0, 1, 2);
        assertFalse(t4.isTriangle());

        Triangle t5 = new Triangle(1, 2, 3);
        assertFalse(t5.isTriangle());

        // Test valid triangles
        Triangle t6 = new Triangle(3, 4, 5);
        assertTrue(t6.isTriangle());

        Triangle t7 = new Triangle(3, 3, 3);
        assertTrue(t7.isTriangle());

        Triangle t8 = new Triangle(1, 2, 2);
        assertTrue(t8.isTriangle());
    }

    @Test
    public void testGetType() {
        // Test invalid triangles
        Triangle t1 = new Triangle(-1, 2, 3);
        assertEquals("Not a triangle", t1.getType());

        Triangle t2 = new Triangle(1, -2, 3);
        assertEquals("Not a triangle", t2.getType());

        Triangle t3 = new Triangle(1, 2, -3);
        assertEquals("Not a triangle", t3.getType());

        Triangle t4 = new Triangle(0, 1, 2);
        assertEquals("Not a triangle", t4.getType());

        Triangle t5 = new Triangle(1, 2, 3);
        assertEquals("Not a triangle", t5.getType());

        // Test valid triangles
        Triangle t6 = new Triangle(3, 4, 5);
        assertEquals("Scalene triangle", t6.getType());

        Triangle t7 = new Triangle(3, 3, 3);
        assertEquals("Equilateral triangle", t7.getType());

        Triangle t8 = new Triangle(1, 2, 2);
        assertEquals("Isosceles triangle", t8.getType());
    }
}
