Lab Report 4

Lab Report 4

So, this week I will run through the lab task where I fix a bug in a file on a remote computer using the terminal!

Step 4

Keystrokes

ssh<space>cs15lsp23et<shift>2ieng6.ucsd.edu<enter>

This is me signing in to ieng6. After hooking up the ssh key, I no longer have to type in password, so there is no need to type those keystrokes!

I sortve wanna figure out how to make a keylogger, but also no. More typing for me… I apologize if there are inaccuracies.

Step 5

Lab7 Fork SSH link

Terminal

Keystrokes

git clone <paste> enter

I cloned the lab7 repository to my ieng6 account directory. Using the ssh link instead of the https link lets me push to the main branch on github. I pasted from my clipboard using right-click and then selecting paste because my keyboard doesn’t have an insert key and, for some reason, in my terminal paste is ctrl+insert.

Step 6

Locating Test Script

JUnit Output

Keystrokes

ls<enter>cd<space>l<tab><enter>ls<enter>bash<space>test.sh<enter>

I navigated to ./lab7 and from there used the bash script test.sh which compiled everything and ran the JUnit tests. I hope you appreciate the tabs I used for super efficiency. Oh!! And one of the two tests ran is a FAILURE!!!!!!! I better fix that………

Step 7

ListExamplesTests.java

import static org.junit.Assert.*;
import org.junit.*;
import java.util.*;
import java.util.ArrayList;


public class ListExamplesTests {
        @Test(timeout = 500)
        public void testMerge1() {
                List<String> l1 = new ArrayList<String>(Arrays.asList("x", "y"));
                List<String> l2 = new ArrayList<String>(Arrays.asList("a", "b"));
                assertArrayEquals(new String[]{ "a", "b", "x", "y"}, ListExamples.merge(l1, l2).toArray());
        }

        @Test(timeout = 500)
        public void testMerge2() {
                List<String> l1 = new ArrayList<String>(Arrays.asList("a", "b", "c"));
                List<String> l2 = new ArrayList<String>(Arrays.asList("c", "d", "e"));
                assertArrayEquals(new String[]{ "a", "b", "c", "c", "d", "e" }, ListExamples.merge(l1, l2).toArray());
        }

}

So, It appears that the error occurs in testMerge2. There must be an error with the merge function that permits the first test to pass but not the second one???? What is it!!!!!???

Opening ListExamples.java in vim

vim editor containing bugged out ListExamples.java

vim editor after fixing the bug

Keystrokes

vim<space><shift>list<shift>examples.java<enter>r2:wq<enter>

I opened up the bugged ListExamples.java with vim. Luckily, when I opened the file, my cursor was already on top of the 1 that causes the bug!!!! The darn incorrect index variable is breaking the test! So I just r to replace and 2 to fix the bug. Then :wq to save and quit. All better!

Step 8

test.sh Command

JUnit Output

Keystrokes

bash<space>test.sh<enter>

Straightforward for this step. I ran the bash script and the two tests got Ok. I fixed her up! Like new polished nails!

Step 9

git status Command

git add Command

git commit Command

git push Command

Github Repository after push

Keystrokes

git<space>status<enter>git<space>add<space><shift>list<shift>examples.java<enter>git<space>commit<space>-m<space><shift>'fixed<space><shift>list<shift>examples.java<shift>'<enter>git<space>push<space>origin<space>main<enter>

What a mouthfull of keystrokes! It was rather simple commiting and pushing, but including all of the <shift>s and enters and spaces makes the keystroke box cluttered as an alabaman attic! So, I used git status to make sure that I could add the changes I made to ListExamples.java. After that worked, I added the file and commited that with message fixed ListExamples.java. Then I pushed it to the main branch of my forked repository. Cut and dry, simple and clean, I think this is mission complete!, or concluded!
