对Triangle进行JUnit测试并设计测试用例使其满足100%语句覆盖并把Java代码给我

好的，以下是Triangle类的Java代码和JUnit测试代码：

Triangle.java

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

    public Triangle(double side1, double side2, double side3) {
        this.side1 = side1;
        this.side2 = side2;
        this.side3 = side3;
    }

    public String getType() {
        if (side1 <= 0 || side2 <= 0 || side3 <= 0) {
            return "Not a triangle";
        }
        if (side1 + side2 <= side3 || side1 + side3 <= side2 || side2 + side3 <= side1) {
            return "Not a triangle";
        }
        if (side1 == side2 && side2 == side3) {
            return "Equilateral";
        }
        if (side1 == side2 || side1 == side3 || side2 == side3) {
            return "Isosceles";
        }
        return "Scalene";
    }
}

TriangleTest.java

import org.junit.Test;

import static org.junit.Assert.assertEquals;

public class TriangleTest {
    @Test
    public void testEquilateralTriangle() {
        Triangle t = new Triangle(2, 2, 2);
        assertEquals("Equilateral", t.getType());
    }

    @Test
    public void testIsoscelesTriangle() {
        Triangle t = new Triangle(2, 2, 3);
        assertEquals("Isosceles", t.getType());
    }

    @Test
    public void testScaleneTriangle() {
        Triangle t = new Triangle(3, 4, 5);
        assertEquals("Scalene", t.getType());
    }

    @Test
    public void testNotATriangle1() {
        Triangle t = new Triangle(0, 2, 3);
        assertEquals("Not a triangle", t.getType());
    }

    @Test
    public void testNotATriangle2() {
        Triangle t = new Triangle(1, 2, 3);
        assertEquals("Not a triangle", t.getType());
    }

    @Test
    public void testNotATriangle3() {
        Triangle t = new Triangle(2, 2, 4);
        assertEquals("Not a triangle", t.getType());
    }
}

这里我们设计了6个测试用例，分别测试了等边三角形、等腰三角形、不等边三角形和非三角形的情况，以覆盖Triangle类中所有的语句。

注：由于输入为double类型，存在精度问题，因此在实际使用时可能需要根据实际情况进行修改。
