I. Introduction of the topic

Write a program that calculates the frequency of English words for a set of text documents.

Second, the source of GitHub links

Https://github.com/liuxu8257/zuoye2

Third, the design of the module test cases, test results

This implementation has three methods, the three methods were tested:

Three Tests to get the string method in the file:

1     @Test 2 public     void Tsetnullfile () throws ioexception{3         file file =null; 4         Deal dos = new Deal (); 5
   
    string result = dos.getstring (file); 6         assertnull (result); 7     } 8      9     @Test10 public     void Testnocontentfile () throws IOException {11 File         file =new file ("D:/empty.txt");         Deal dos = new Deal ();         String result = dos.getstring (file)         , Assertequals ("", result);     }16     17     @Test18 public     void Testnormalfile () throws IOException {         file file =new file ("D:/normal.txt"); 20         Deal dos = new Deal ();         String result = dos.getstring (file)         , Assertequals ("hello,my name is matin,i am thirty-three years old.", result); (+     }
   

The methods for extracting words are tested as follows:

1     @Test 2 public     void Testtakeword () throws IOException {3         File file =new file ("D:/normal.txt"); 4         Deal D OS = new Deal (); 5         String str = dos.getstring (file), 6         list<string> result = Dos.takeword (str); 7 for         (String show: Result) {8             System.out.print (show); 9         }10     }    

The test prints the result: Hello my name is matin I am thirty three years old

The following tests are done for calculating the word frequency:

1     @Test 2 public     void Testfrequency () {3         list<string> List = new Arraylist<string> (); 4         List.add ("three"); 5         List.add ("three"), 6         list.add ("a"), 7         list.add ("a"), 8         list.add ("three"), 9         list.add (" One "),         List.add (" one "),         Deal dos = new Deal ();         HashMap map = dos.getfrequency (list); 14         the         Iterator iter = Map.entryset (). Iterator (); +         (Iter.hasnext ()) {map.entry Entry             = (map.entry) Iter.next ();             string key = (String) entry.getkey ();             int val = (Integer) entry.getvalue ();             System.out.println (key+ ":" +val);         }22     }

The test prints the result:

Three:3

Two:2

　　One:2

　　Test results:

　　

Iv. problems and solutions, experience.

This homework I learned some of the software testing operations, a preliminary understanding of software testing has stimulated a strong interest in learning will be good to learn such courses
