A simple environment for practicing unit tests

In this project we use a lib.js file to hold simple functions which will be tested.

The functions are:

1. factorial - Expects a number as an input. The function returns the factorial of a given number (example - factorial(5) == 1*2*3*4*5 = 120).

2. palindrome - Expects a string as an input. The function returns true if the given string or number is a palindrome, otherwise a false is returned.

3. randomString - Expects a number indicating the string's length. The function generates a string containing only letters ([a-z], [A-Z]) and numbers ([0-9]).

4. shift - Expects a string and a number to indicate the desired number of shifts. The function returns a shifted string. A positive number will shift the string to the right. A Negative number will shift the string to the left. A value of zero will return the string as is with no shifts.

5. sort - Expects a string as an input. The function returns a sorted string in an ascending order.

unit.js

contains all the tests for all the functions:

1. Assert that the factorial function is returning the factorial of the given number.

2. Assert that the palindrome function returns true if the given string is actually palindrome.

3. Assert that the palindrome function returns true if the given number is actually palindrome.

4. Assert that the randomString function returns a string with the length equal to the given number.

5. Assert that the shift function returns a string shifted to the right when given a positive number of shifts.

6. Assert that the shift function returns a string shifted to the left when given a negative number of shifts.

7. Assert that the shift function returns the same input string when given a zero value as number of shifts.

8. Assert that the sort function returns a new sorted string in ascending order.
