To complete this assignment:

$1)$ Create four $(4)$ sets of black$-$box functional unit test cases and unit tests to test the following public components of the Reservation class:

a$)$ The constructor & getters methods

b$)$ The setters & getters methods

c$)$ The calculateReservationNumberOfDays$()$ method

d$)$ The calculateReservationBillAmount$()$ method

For each of these four $(4)$ sets complete the following:

a$)$ Create a set of black$-$box functional unit test cases $($composed of Selected Inputs, Expected Result, Actual Result, Pass$|$Fail$)$ to test the designated public component$($s$)$ of the Reservation Class.

b$)$ Using the provided $*.$jar file, code Java unit tests to execute your test cases and record their Pass$|$Fail verdicts for the designated public component$($s$)$ of the Reservation class.

On the Java command line, compile and execute your single test file $($e$.$g$.,$ TestReservation.java$)$ using this single java command $($note that you need to specify the $*.$java extension for your single test file$)$:

java $-$cp w$6.$jar TestReservation.java

c$)$ Explain your approach to black$-$box unit test designated public component$($s$)$ of the Reservation class, the steps you followed to create it$,$ and the rationale behind your test cases and their results.

Importing the jar file provided for the assignment just ends with me receiving the error that import cannot be resolved.
