"Software Test" experiment two unit test

1. (1) Write a program that parses the frequency of occurrences of each word in a string and displays the word and the frequency at which it appears. (the words are separated by a space, such as "Hello World My First Unit Test");

Import Java.util.HashMap;

Import Java.util.Iterator;

Import Java.util.Map;

Import Java.util.Set;

public class Demo {

public void Wordscount (String str) {

string[] Wordsarray = Str.split ("");

map<string, integer> wordsmap = new hashmap<string, integer> ();

for (String Word:wordsarray) {

if (Wordsmap.containskey (word)) {

Wordsmap.put (Word, wordsmap.get (word) + 1);

}

else {

Wordsmap.put (Word, 1);

}

}

set<string> Setkey = Wordsmap.keyset ();

iterator<string> Itkey = Setkey.iterator ();

while (Itkey.hasnext ()) {

String Word = Itkey.next (). toString ();

int count = Wordsmap.get (word);

System.out.println ("Word:" + Word + "appears" + Count + "Times");

}

}

}

(2) Writing unit tests for testing;

Import static org.junit.assert.*;

Import Org.junit.Test;

public class Demotest {

@Test

public void Test () {

Demo Demo = new Demo ();

Demo.wordscount ("Hello This is A test test");

}

}

(3) Use Elcemma to view code coverage, requiring coverage to reach 100%.

2. (1) The order of words in an English sentence is reversed and then output. For example, enter "How IS is", output "you is how";

public class Demo {
public void Upsidedown (String str) {
string[] Wordsarray = Str.split ("");
System.out.print ("Reverse word output:");
for (int i = wordsarray.length-1; I >= 0; i--) {
System.out.print (Wordsarray[i] + "");
}
}
}

(2) Writing unit tests for testing;

Import static org.junit.assert.*;
Import Org.junit.Test;
public class Demotest {
@Test
public void Test () {
Demo Demo = new Demo ();
Demo.upsidedown ("Hello This is A test test");
}
}
