Code details

 

A. Requirement Analysis:

A. Test the addition, subtraction, multiplication, division, and Division functions.

B. enter invalid characters for testing

C. test if the value is out of range

D. Test the result except 0

 

B. design the test framework and simulate the test data (view code)

1. Test the addition, subtraction, multiplication, division, and Division functions.

@Test    public void testAdd() {          calc.add(5,8);          assertEquals(13, Integer.parseInt(calc.getResult()));    }     @Test    public void testSubstract() {        calc.substract(5,8);         assertEquals(-3, Integer.parseInt(calc.getResult()));    }     @Test    public void testMultiply() {         calc.multiply(5,8);         assertEquals(40, Integer.parseInt(calc.getResult()));    }     @Test    public void testDivide() {         calc.divide(5,8);         assertEquals(String.valueOf("5/8"), calc.getResult());    }     @Test    public void testAdd2() {        calc.add2(2,4,2,3);         assertEquals(String.valueOf("7/6"), calc.getResult());    }     @Test    public void testSubstract2() {         calc.substract2(2,4,2,3);         assertEquals(String.valueOf("1/-6"), calc.getResult());    }     @Test    public void testMultiply2() {        calc.multiply2(2,4,2,3);         assertEquals(String.valueOf("1/3"), calc.getResult());    }     @Test    public void testDivide2() {        calc.divide2(2,4,2,3);         assertEquals(String.valueOf("3/4"), calc.getResult());    }

This part of function code is not pasted for a long time and will be included in the coding.

 

2. enter invalid characters for testing

@ Testpublic void testPanduanzifu () {// String s = calc. getResult (); calc. panduanzifu ("4/7! # @ $ "); AssertEquals (" input error ", calc. getResult ();} public void panduanzifu (String s) // judge the input character, {char arr [] = s. toCharArray (); for (int I = 0; I <s. length (); I ++) {if (arr [I] <45) | (arr [I]> 58 )) {sum1 = "input error ";}}}

 

　　

3. The value is out of range for testing.

@ Testpublic void testRange () {calc. range (11,3); assertEquals ("outrange", calc. getResult ();} public void range (int x, int y) // range judgment {if (x <0 | x> 10) | (y <0 | y> 10) sum1 = "outrange ";}

 

4. Test results except 0

@ Testpublic void testZero () {calc. zero ("4/0"); assertEquals ("zero error", calc. getResult ();} public void zero (String s) {// The result except 0 error s = s. substring (s. length ()-2, s. length (); if (s. equals ("/0") {sum1 = "zero error ";}}

 

Result

If the result sum1 returned from the test data is the same as the preset result, the operation is correct.

 

Summary and feelings

In this pair programming 2-unit test, I always felt that nothing would happen, as if I had entered a blind zone of knowledge. At the beginning, I was confused and did not even know what to do. I had to finish the task slowly through the words, deeds, and online search of my teammates. Testing is very important for a program. A system testing will make the program running safer and reduce the occurrence of bugs. After this assignment, I also found that my programming skills were insufficient, and my knowledge was incomplete. I still needed to improve my skills.

Hamburger rating

 Put a piece of bread first: what two people have in common has been said last time, this is the second cooperation, the two people are more tacit;

Put meat and condiments on it: the Knowledge System of teammates is relatively complete. This time I was overwhelmed and helped a lot. Although the roles of the two were exchanged, but more is the dedication of rufan;

Put it on the bread: the second cooperation was more tacit, and the efficiency naturally increased, cheering for the progress of the two people!
