Test Writing: Validate Brackets

Created By: Justin Maier

/ Version: 2024.12.0

Complete the method below that takes in a String containing only the enclosing characters '(', ')', '[', and ']'. The function should determine whether the ordering and pairing of the brackets form a valid expression. For example,

• "[()]" is valid.
• "[()[]" is not valid since the first bracket '[' is not matched.
• "[(])" is not valid as the outer closing bracket ']' occurs before the inner closing bracket ')'.

Test Design Challenge

You're challenge is to write tests for this problem described above.

• Provide a method named test that accepts no arguments and does not return a value.
• If the implementation of the class described above is incorrect, your test method should throw an exception.
• If it is correct, do not throw an exception.
• You may want to use Java's assert method
