Software test based on the Machine Experiment 1 (triangle judgment)

I. 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. Installing Eclemma

Two. Write Triangle and Triangletest:

1. Main code (judging triangle properties)

1  Packageexample;2 3 /**4 * Created by Ev_eraser on 2016/3/18.5  */6  Public classMyclass {7      PublicString Triangle (intAintBintc) {8         if(A + b < C | | A + c < b | | B + C <a)9             return"Nottriangle";Ten         if(A = = b && b = =c) One             return"Isosceles"; A         if(A = = B | | b = = c | | a = =c) -             return"Equilateral"; -         Else the             return"Scalene"; -     } -}

2. Testing

 Packageexample;ImportOrg.junit.After;ImportOrg.junit.Before;Importorg.junit.Test;ImportOrg.junit.runner.RunWith;Importorg.junit.runners.Parameterized;Importjava.util.ArrayList;Importjava.util.Arrays;Importjava.util.Collection;Import Staticorg.junit.assert.*; @RunWith (parameterized.class) Public classMyclasstest {PrivateMyclass Myclass; Private intinput1; Private intInput2; Private intINPUT3; PrivateString expected;  PublicMyclasstest (intINPUT1,intInput2,intinput3,string Expected) {         This. INPUT1 =input1;  This. Input2 =Input2;  This. INPUT3 =INPUT3;  This. Expected =expected; } @Before Public voidSetUp ()throwsException {myClass=NewMyclass (); } @Parameterized. Parameters Public StaticCollection<object[]>GetData () {returnArrays.aslist (Newobject[][]{{2,2,2, "Isosceles"},            {2,2,3, "equilateral"},            {2,4,3, "Scalene"},            {2,9,2, "Nottriangle"}    }); }//@After//Public void TearDown () throws Exception {////    }@Test Public voidTesttriangle ()throwsException {assertequals ( This. Expected, Myclass.triangle (INPUT1,INPUT2,INPUT3)); }}

3. Test results

All four test cases pass, coverage 90%
