This lab report reproduces the task from the CSE 15L Spring 2023 Week 7 Lab.

   

Setting Up (Steps 1 to 3)

1. Delete any existing forks of the repository on GitHub account with contents found here.

2. Fork the repository (from above).

3. Optional: Start a timer if you are timing yourself!

   

Step 4: Log into ieng6

Keys pressed:
ssh <space> cs15lsp23mh@ieng6.ucsd.edu <enter>

• The ssh command (followed by an account) is needed to log in to ieng6.

   

Step 5: Clone your fork of the repository from your Github account

Keys pressed:
git <space> clone <space> git@github.com:yal103/lab7.git <enter>

• The git clone command (followed by the GitHub repository link) clones the repository into the ieng6 account.
• Note: You can use <CTRL-C> and <CTRL-V> to copy and paste the repository SSH key: git@github.com:yal103/lab7.git.

   

Step 6: Run the tests, demonstrating they fail

Keys pressed:
cd <space> lab7 <enter>

• Changes to the cloned lab7 directory

 

javac <space> -cp <space> .:lib/hamcrest-core-1.3.jar:lib/junit-4.13.2.jar <space> *.java <enter>

java <space> -cp <space> .:lib/hamcrest-core-1.3.jar:lib/junit-4.13.2.jar org.junit.runner.JUnitCore <space> ListExamplesTests <space>

• Compiles and runs the JUnit tests for ListExamples.
• The tests should fail.
• Note: You can use <CTRL-C> and <CTRL-V> to copy and paste the commands.
  • javac -cp .:lib/hamcrest-core-1.3.jar:lib/junit-4.13.2.jar *.java followed by <enter>
  • java -cp .:lib/hamcrest-core-1.3.jar:lib/junit-4.13.2.jar org.junit.runner.JUnitCore ListExamplesTests followed by <enter>

   

Step 7: Edit the code file ListExamples.java to fix the failing test

Keys pressed:
vim <space> ListExamples.java <enter>

• Views the contents in ListExamples.java using the built-in vim text editor.

 

/ange <enter> <down> r2 :wq <enter>

• In vim, / followed by a string (and <enter>) searches the file for the occurences of that string.
• In this case, ListExamples.java only has one occurrence of the strin ange (in the word change above the the needed change).
  • The terminal cursor moves to the first occurrence of ange in the file.
• Pressing <down> shifts the terminal cursor to the 1 in the index1 that needs to be changed to index2.
• In vim, r followed by a character 2 changes the character highlighted by the terminal (1) into 2.
  • index1 is changed to index2.
• r2 does not change the mode to insert mode, not we do not need to press <esc>.
• :wq followed by <enter> saves and exits out of the vim text editor.

   

Step 8: Run the tests, demonstrating that they now succeed

Keys pressed:
<up> <up> <up> <enter> , <up> <up> <up> <enter>

• The javac -cp .:lib/hamcrest-core-1.3.jar:lib/junit-4.13.2.jar *.java command was 3 up in my command history, so I used the up arrow to access it.
• Similarly, after the previous command was run, the java -cp .:lib/hamcrest-core-1.3.jar:lib/junit-4.13.2.jar org.junit.runner.JUnitCore ListExamplesTests command was 3 up in my command history, so I used the up arrow to access it.
• The tests should pass this time.

   

Step 9: Commit and push the resulting change to your Github account

Keys pressed:
git <space> add <spa（っ＾▿＾）ce> ListExamples.java <enter>
git <space> commit <space> -m <space> "Updated" <enter>
git <space> push <space> origin <space> main <enter>

• The git add, git commit, and git push commands commit and push the changes made to ListExamples.java to the GitHub repository.

The file should be updated in the GitHub repository, which the commit message:
