Test Program using Eclipse

Run the JUnit tests

Open the cloned Project - QuantcastGithubProject

Open Eclipse > Import Project QuantcastGithubProject

Right-click on MostActiveCookieTest.java

Run As > Junit Test

Additional Information

I have used apache.commons.cli library to use “-d” as parameter to enter date in command line.

The above command line adds the class path of external libraries , takes cookieData.csv as 1st argument and input date as “-d ” parameter.

Junit tests are added to MostActiveCookieTest.java

The program has been designed such that an exception will be thrown in the following cases:

• If the input CSV file path passed in the argument cannot be located at specified location

• If the input CSV file path is not added as argument in the command line.

• If input date is not passed as “-d” parameter.

• If the input date entered is not in the correct format i.e. yyyy-MM-dd .
