Notes on Testing • Unit Testing - creates a test case for each module of code that been authored. The goal is to ensure correctness of individual methods • Integration Testing - modules that were individually tested are now tested as a collection. This form of testing looks at the larger picture and determines if bugs are present when modules are brought together • System Testing - seeks to test the entire software system and how it adheres to the requirements (also known as alpha or beta tests) • The code-coverage approach designs test cases to ensure that each statement in the program is executed. • The data-coverage approach designs test cases to ensure that the limits of the allowable data are covered. Often testing is a combination of code and data coverage. • Regression testing is the process of testing changes to computer programs to make sure that the older programming still works with the new changes. Regression testing is a normal part of the program development process and, in larger companies, is done by code testing specialists. Test department coders develop code test scenarios and exercises that will test new units of code after they have been written. These test cases form what becomes thetest bucket. Before a new version of a software product is released, the old test cases are run against the new version to make sure that all the old capabilities still work. The reason they might not work is because changing or adding new code to a program can easily introduce errors into code that is not intended to be changed. • A test plan for a program is a document that specifies the test cases that should be run, the reason for each test case, and the expected output for each test case. The test cases should be chosen carefully. Implementing a test plan means that you run each of the test cases described in the test plan and record the results. If the results are not as expected, you must go back to your program

JAVA

Answer 1

HI,

Please find below code written in JAVA. Also I have attached program and output screenshot for your reference.

Code:-

import java.util.Scanner;

public class Temperature{

public static void main(String []args){
  
int temp;
  
Scanner sc = new Scanner(System.in);
  
while(sc.hasNextInt())
{
  
temp = sc.nextInt();
  
if(temp <= 32)
{
System.out.println("Today is a Cold day!");
}
else if(temp <= 85)
{
System.out.println("Today is a Nice day!");
}
else
{
System.out.println("Today is a Hot day!");
}
}
}
}

1 import java.util.Scanner; 3 public class Temperature{ public static void main(String []args) { int temp; Scanner sc = new Scanner(System.in); while(sc.hasNextInt()) temp = sc.nextInt(); if(temp <= 32) 17. System.out.println("Today is a cold day!"); else if(temp <= 85) System.out.println("Today is a nice day!"); else System.out.println("Today is a Hot day!"); 30 }

NOUT O UN $javac Temperature.java $java -Xmx128M -Xms 16M Temperature Today is a cold day! Today is a nice day! Today is a cold day! Today is a nice day! Today is a Hot day! Today is a cold day!
