The purpose of this quiz is to ensure that you can

run tests

write tests

identify bugs using tests

fix the bugs

Instructions:

Create a project named IST311LifeCycleQuiz;

Implement the classes identified below;

Export the project to a zip file (This is in the menu for IntelliJ at File->Export to Zip file...)

Code Specification:

We are solving a classic interview problem, finding the longest prefix in an ArrayList of Strings. These types of problems feature heavily in interviews, and String manipulation is a common practice that you will need to master to be an effective developer. The problem statement is:

You must find the longest common prefix in an array of Strings. If there is no common prefix, return an empty string (i.e. ""). If there is a common prefix, return it as a String:

Example: in this array ["flower","flow","flight"], we would return "fl"Example: in this array ["flower","flow"], we would return "flow"Example: in this array ["dog","racecar","car"], we would return ""Example: in this array [], we would return "" as there are no strings at all

Step 1:

Below are two classes LongestCommonPrefix and LongestCommonPrefixTest. Create the corresponding java files (they must have the same name), and ensure that you can run your tests.

Step 2:

Write a new test where you pass an empty ArrayList to the findLongestCommonPrefix method. This test will fail, in fact, it will through an error. You need to figure out how to fix this, hint, it should return an empty string ("") if there are no elements in the ArrayList. Include at least one assert in the test.

Step 3:

Find a way to fix the code so that the test passes.

Step 4 (Extra Credit):

Write another test that would fail given the code below and correct the code so that it passes, this must include at least assert in the test.

Step 5:

Zip up the project and turn it in.
