Software Test Experiment One

The installation of JUnit, Hamcrest, and Eclemma.

1.junit and Hamcrest add Junit-4.12.jar and Hamcrest-all-1.3.jar in build path by adding external jars after creating a new JUNITHW1 project.

2.eclemma Click Help-eclipse marketplace-find-eclemma Install under Eclipse.

Second, the preparation of triangle and TestTriangle1.

1.triangle-Judging triangle type

public class Triangle {int[] data;  Triangle () {data = new int[3], public void SetData (int[] number) {for (int i = 0;i < data.length;i++) {Data[i] = Numbe R[i]; }} public     String Checktriangle () {for     (int i = 0;i < data.length;i++) {      if (data[i]<=0)      return " Illegal ";     }     if (data[0]+data[1]<=data[2]| | data[0]+data[2]<=data[1]| | Data[1]+data[2]<=data[0]) {     return "not triangle";     }     else if (data[0]==data[1]&&data[0]==data[2]) {     return "equilateral";     }     else if (data[0]==data[1]| | data[0]==data[2]| | Data[1]==data[2]) {     return "isosceles";     }     else     return "Scalene";     }}

Third, test results
