1. Log into ineg6
ssh [email protected]<enter>
Using the ssh command, we can secure an encrypted connection between two hosts. Because we generated SSH keys, there is no need to type in a password when logging in. Now we are entering commands from the ieng6 host server, not our local server.
2. Clone your fork of the repository from your Github account
git clone [email protected]:serrachow/lab7.git<enter>
Because we have an SSH key used to authenticate Github, we can use the SSH url to clone the forked Github repository. Because our account has access, this will help in cloning and pushing future changes to the repository. The git clone command makes a copy of the repository into our account on the ieng6 server.
3. Run the tests, demonstrating that they fail
cd lab7<enter>
ls<enter>
javac -cp .:lib/hamcrest-core-1.3.jar:lib/junit-4.13.2.jar *.java<enter>
java -cp .:lib/hamcrest-core-1.3.jar:lib/junit-4.13.2.jar org.junit.runner.JUnitCore ListExamplesTests<enter>
cat ListExamplesTests.java<enter>
First we use cd lab7 to change the directory we're in into the lab7 directory. Then we use the command ls to make sure that ListExamples.java and ListExamplesTest.java are inside the lab7 directory. We run javac -cp .:lib/hamcrest-core-1.3.jar:lib/junit-4.13.2.jar *.java and java -cp .:lib/hamcrest-core-1.3.jar:lib/junit-4.13.2.jar org.junit.runner.JUnitCore ListExamplesTests to compile and run the JUnit tests. From the screenshot, we can tell that testMerge2 in ListExamplesTests failed. If we use cat ListExamplesTests.java to see inside the tester file, we can see that we must fix the merge method.
4. Edit the code file to fix the failing test
nano ListExamples.java<enter>
<Ctrl+W>while(index2 < list2.size())<enter>
<down><down><right-arrow><right-arrow><right-arrow><right-arrow><right-arrow><right-arrow><right-arrow><right-arrow>
<back-space>2
<Ctrl-O><enter><Ctrl-X>
First we must use nano to edit the ListExamples.java document. We type nano ListExamples.java to bring up a screen to edit the file. Using Ctrl+W we can use the nano search function to take us nearest to where we want to edit, which is within the while for loop while(index 2 < list2.size()). Then we need to move two lines downward and eight times right to change index1 to index2. Then we just erase the 1 and change it to 2 using the back-space button. Then we can use Ctrl-O to save and Ctrl-x to exit.
5. Run the tests, demonstrating that they now succeed
<up><up><up><enter>
(to find javac -cp .:lib/hamcrest-core-1.3.jar:lib/junit-4.13.2.jar *.java)
<up><up><up><up><enter>
(to find java -cp .:lib/hamcrest-core-1.3.jar:lib/junit-4.13.2.jar org.junit.runner.JUnitCore ListExamplesTests)
Now, instead of retyping the javac and java commands, we can press the up arrow three times to find the compile command and press enter to run. Then we can press the up arrow four times and find our previous java run command and press enter to run the tester file. From the screenshot, we can see the tester file now passes and our code is now fixed.
6. Commit and push the resulting change to your Github account
git add ListExamples.java<enter>
git commit -m "fixed ListExamples.java"<enter>
git push origin main<enter>
First we use git add to add a change in the working directory to the staging area. Then we use git commit that captures a screenshot of the changes, along wth a message to explain what we did. Lastly, we use git push origin main to upload the changes from the local repository to the remote repository.
On Github, the fixed code:
