It aims to ensure proper carry behavior. + +Execution: + Arrange: Initialize a `BitSet` where multiple consecutive bits are set at the least significant positions, and set `size` to the bit length. + Act: Call the `increment` method with the initialized `BitSet` and size. + Assert: Verify that the consecutive set bits are cleared and the next higher unset bit is set to true, and confirm the return value is true. + +Validation: + The test verifies the carry propagation of the binary addition simulation within the `BitSet`, ensuring correctness where bits roll over. + +--- + +Scenario 3: Verify

TestName: testIncrementSizeLessThanBitSetLength. + Description: This test validates that the `increment` method operates only on the specified size of the `BitSet`, leaving bits outside the range unaffected. + +Execution: + Arrange: Create a `BitSet` with some bits set and size explicitly smaller than the `BitSet` length. + Act: Call the `increment` method with the `BitSet` and size. + Assert:

It checks whether the method appropriately handles this edge case and returns an empty array. + +Execution: + Arrange: Create an empty array of type Integer (e.g., `Integer[] array = {};`). + Act: Invoke the `sort` method on the `BitonicSort` object using the empty array. + Assert: Use assertions to ensure the method returns an empty array. + +Validation: + The assertion ensures that the method handles edge cases for empty input correctly, as expected, without throwing errors or null pointers. This is significant for ensuring robust application behavior in scenarios requiring empty array processing. + + +*/ + +// ********RoostGPT******** + +package com.thealgorithms.sorts; + +import org.junit.jupiter.api.Test;

elements, and produces the expected sorting result across positive and negative values. + +Scenario 6: Sorting an array with duplicate integers + +Details: + TestName: sortWithDuplicateIntegerValues + Description: This test verifies that the `sort` method can correctly handle arrays containing duplicate integers, sorting them while preserving duplicates in ascending order. + +Execution: + Arrange: Prepare an array with duplicate integers, such as `{4, 4, 1, 2, 2, 3}`. + Act: Pass the array with duplicates into the `sort` method. + Assert: Assert that the output array matches `{1, 2, 2, 3, 4, 4}` using `assertArrayEquals`. + +Validation: + The assertion ensures the algorithm retains all instances of duplicate values and correctly integrates them in sorted order. + +Scenario 7: Sorting an array with strings in alphabetical order + +Details: + TestName: sortWithAlphabeticalStringArray + Description: This test checks if the `sort` method correctly orders strings alphabetically, ensuring lexicographical comparisons are handled effectively. + +Execution: + Arrange: Prepare an array with string values such as `{ "apple", "dog", "cat", "banana" }`. + Act: Pass the string array into the `sort` method. + Assert: Assert that the output matches `{ "apple", "banana", "cat", "dog" }` using `assertArrayEquals`. + +Validation: + This test verifies that the algorithm performs string comparisons appropriately and produces valid alphabetical order regardless of initial arrangement. + +Scenario 8: Handling arrays with Unicode strings + +Details: + TestName: sortWithUnicodeStringArray + Description: This test verifies the `sort` method's ability to correctly handle Unicode characters in strings for sorting, checking for lexicographically expected output. + +Execution: + Arrange: Prepare an array such as `{ "Ångström", "apple", "Ángel", "banana" }`. + Act: Pass the Unicode string array into the `sort` method. + Assert: Assert that the output matches `{ "Ángel", "Ångström", "apple", "banana" }` using `assertArrayEquals`. + +Validation: + The test ensures that Unicode characters are considered correctly during comparisons and that boundaries like accented characters are accounted for in sorting. + +Scenario 9: Sorting an array with duplicate strings + +Details: + TestName: sortWithDuplicateStringValues + Description: This test ensures that the `sort` method can handle arrays with duplicate strings, maintaining duplicates and sorting accurately. + +Execution: + Arrange: Prepare an array with duplicate strings, such as `{ "apple", "banana", "apple", "cherry" }`. + Act: Pass the string array into the `sort` method. + Assert: Assert that the output matches `{ "apple", "apple", "banana", "cherry" }` using `assertArrayEquals`. + +Validation: + This test guarantees that duplicate strings are appropriately handled and remain in the correct sorted order within the output array. + +Scenario 10: Sorting an array with integers at random positions + +Details: + TestName: sortWithRandomIntegerArray + Description: This test verifies that the `sort` method successfully arranges integers that initially occur in arbitrary positions into correct ascending order. + +Execution: + Arrange: Prepare an array with random values, such as `{8, 3, 1, 6, 7, 4}`. + Act: Pass the randomly ordered array into the `sort` method. + Assert: Assert that the output matches `{1, 3, 4, 6, 7, 8}` using `assertArrayEquals`. + +Validation: + The assertion confirms the algorithm's robustness in handling unsorted inputs effectively and producing the expected sorted output regardless of starting arrangement. + +Scenario 11: Sorting an array containing edge-case numbers like Integer.MAX_VALUE and Integer.MIN_VALUE + +Details: + TestName: sortWithEdgeCasesOfIntegers + Description: This test validates that the `sort` method can handle extreme numerical values, including the smallest and largest possible integers, and sorts them accurately. + +Execution: + Arrange: Prepare an array with values `{ Integer.MAX_VALUE, Integer.MIN_VALUE, 0, -100, 100 }`. + Act: Pass the edge-case array into the `sort` method. + Assert: Assert that the output matches `{ Integer.MIN_VALUE, -100, 0, 100, Integer.MAX_VALUE }` using `assertArrayEquals`. + +Validation: + This test demonstrates the algorithm's ability to handle the full range of

validateArrayPrintingCorrectly + Description: This scenario checks if the `printArray` method correctly prints all elements of a given array in the expected format. It verifies that each value in the array is printed sequentially with spaces between elements and ends with a new line. +Execution: + Arrange: Prepare an array with distinct integer values such as {1, 2, 3, 4, 5}. Also provide the correct array size. + Act: Invoke the `printArray` method with the array and its size as parameters. + Assert: Compare the output printed to the console with the expected string "1 2 3 4 5\n". +Validation: + This test ensures the method correctly processes and formats array elements when provided with valid input. It verifies the basic functionality of iterating over the elements and printing them in the specified format. + +--- + +Scenario [2]: Handle Empty Array + +Details: + TestName: handleEmptyArrayPrinting + Description: Test behavior of the `printArray` method when the input array is empty. The expected output should be an empty line. +Execution: + Arrange: Provide an empty array {} as input with size 0. + Act: Call the `printArray` method with the array and its size. + Assert: Check the output printed to the console, which should contain only a newline character. +Validation: + This test ensures the method handles edge cases correctly, specifically when the array is empty. It verifies that no errors occur during printing, and output is as expected. + +--- + +Scenario [3]: Validate Correct Output for Array with Single Element + +Details: + TestName: validateSingleElementArrayPrint + Description: Verify the output generated by the `printArray` method for an array containing a single element. +Execution: + Arrange: Provide an array {7} with a size of 1. + Act: Invoke the `printArray` method with these inputs. + Assert: Compare the output printed to the console with the expected string "7\n". +Validation: + This test checks the robustness of the method when handling minimal input data, ensuring that arrays with one element are properly printed. + +--- + +Scenario [4]: Validate Correct Printing of Zero Elements in Array + +Details: + TestName: validatePrintWithZeroArrayElements + Description: Test the method's behavior when the array contains only zeros.

an empty input array. +Execution: + Arrange: Create an empty array of type `Integer` to simulate the input for the method. + Act: Invoke the `sort` method from `StrandSort` with the created empty array. + Assert: Use JUnit assertions to confirm that the output array is also empty. +Validation: + This test ensures that the implementation can handle the edge case where the input array has no elements, returning a valid empty array rather than throwing an error. + +Scenario 2: Sorts an array with a single element correctly + +Details: + TestName: sortSingleElement + Description: Checks that the `sort` method preserves the single element when an array with one element is provided. +Execution: + Arrange: Create an array with one element (e.g., `Integer` array with a single value). + Act: Invoke the `sort` method with the single-element array as the input. + Assert: Assert that the output array matches the input array. +Validation: + Confirms that the method correctly handles arrays with one element, avoiding unnecessary operations while preserving the element. + +Scenario 3: Sorts a descending array of integers correctly + +Details: + TestName: sortDescendingIntegerArray + Description: Tests if the method can sort an integer array that is initially sorted in descending order. +Execution: + Arrange: Create an integer array sorted in descending order (e.g., `[5, 4, 3, 2, 1]`). + Act: Use the `sort` method to sort the array. + Assert: Use assertions to verify that the resulting array is sorted in ascending order. +Validation: + Ensures the algorithm performs correctly when sorting arrays that require the maximum degree of modification to reach an ascending order. + +Scenario 4: Sorts an array with duplicate values correctly + +Details: + TestName: sortArrayWithDuplicates + Description: Validates that the method can handle arrays containing duplicate values and correctly sort them. +Execution: + Arrange: Prepare an integer array with duplicate elements (e.g., `[3, 5, 3, 1, 5]`). + Act: Invoke the `sort` method on this array. + Assert: Check that the sorted array contains all elements in ascending order with duplicates preserved. +Validation: + Confirms that the method retains duplicates and places them in their correct sorted position, maintaining data integrity. + +Scenario 5: Sorts an array with negative and positive integers + +Details: + TestName: sortArrayWithNegativeAndPositiveValues + Description: Examines whether the method can handle arrays with both positive and negative integers correctly. +Execution: + Arrange: Create an integer array containing both negative and positive values (e.g., `[-3, 5, -1, 2, -4]`). + Act: Apply the `sort` method to the array. + Assert: Verify that the resulting output is sorted in ascending order. +Validation: + Ensures correct functionality of the sorting method when the input array spans both negative and positive ranges. + +Scenario 6: Sorts an array of strings correctly in lexicographic order + +Details: + TestName: sortStringArray + Description: Validates that the method sorts an array of strings in lexicographic order irrespective of their initial order. +Execution: + Arrange: Construct a string array with mixed order (e.g., `["apple", "dog", "cat", "banana"]`). + Act: Pass the array to the `sort` method. + Assert: Confirm that the resulting array is sorted lexicographically (e.g., `["apple", "banana", "cat", "dog"]`). +Validation: + Ensures that the method can correctly work with non-numerical arrays and sort strings based on natural lexicographical order. + +Scenario 7: Handles an already sorted array correctly without altering it + +Details: + TestName: sortAlreadySortedArray + Description: Ensures that the `sort` method does not unnecessarily modify an array that is already sorted in ascending order. +Execution: + Arrange: Create an array already sorted in ascending order (e.g., `[1, 2, 3, 4, 5]`). + Act: Invoke the `sort` method using this input array. + Assert: Compare the output to the original array to confirm they match. +Validation: + Confirms that the method avoids redundant operations and preserves the arrangement of pre-sorted arrays. + +Scenario 8: Sorts arrays with mixed data types (e.g., Double and Integer) + +Details: + TestName: sortMixedDataTypesArray + Description: Tests if the method can handle mixed numeric types like `Double` and `Integer`, sorting them correctly. +Execution: + Arrange: Construct an array with mixed numeric types (e.g., `[3.5, 2.1, 5]`). + Act: Apply the `sort` method on the mixed data array. + Assert: Assert that the sorted array maintains correct order (e.g., `[2.1, 3.5, 5]`). +Validation: + Establishes confidence in the type-generalized implementation of the method and its ability to sort mixed numeric types transparently. + +Scenario 9: Sorts arrays with extreme values (e.g., Integer.MIN_VALUE and Integer.MAX_VALUE) + +Details: + TestName: sortArrayWithExtremeValues + Description: Tests if the method can handle arrays containing extreme values like `Integer.MIN_VALUE` and `Integer.MAX_VALUE`. +Execution: + Arrange: Create an array such as `[Integer.MAX_VALUE, Integer.MIN_VALUE, 0]`. + Act: Use the `sort` method to sort the array. + Assert: Verify that the output is correctly sorted in ascending order (e.g., `[Integer.MIN_VALUE, 0, Integer.MAX_VALUE]`). +Validation: + Verifies the robustness of the sorting algorithm, confirming it can handle inputs with extreme numerical ranges. + +Scenario 10: Handles a `null` array gracefully + +Details: + TestName: sortNullArray + Description: Validates that the method throws a `NullPointerException` when a null input array is provided, as expected. +Execution: + Arrange: Provide a null array as input to the method. + Act: Invoke the `sort` method with this null input. + Assert: Use assertions to verify that a `NullPointerException` is thrown. +Validation: + Ensures that the method handles null inputs appropriately by throwing the expected exception rather than returning a truncated array or crashing. + +Scenario 11: Sorts an array with symbols/special characters lexicographically + +Details: + TestName: sortArrayWithSymbols + Description: Verifies that the method can lexicographically sort arrays containing special characters, ignoring symbol priorities. +Execution: + Arrange: Create an array with strings containing symbols like `["@a", "$b", "1c", "!d"]`. + Act: Apply the `sort` method to the array. + Assert: Assert that the symbols are sorted lexicographically (e.g., `["!d", "$b", "1c", "@a"]`). +Validation: + Confirms that sorting logic works transparently for strings with special characters, adhering to lexicographical sorting order. +

It checks if the method correctly returns an empty array without any errors. +Execution: + Arrange: Initialize an empty array of any type to test. + Act: Call the `sort` method with the empty array as an argument. + Assert: Use JUnit's `assertArrayEquals` to ensure the returned array is also empty. +Validation: + This test ensures the method handles empty input gracefully, which is important for edge case handling. An empty array should not cause exceptions and should return an empty array without modifications. + +--- + +Scenario 2: Sort an array with a single element + +Details: + TestName: sortSingleElementArray + Description: This test ensures that when the `sort` method is invoked on an array containing only one element, the method returns the same array without any modifications. +Execution: + Arrange: Initialize an array with a single element, either a numeric or a string value. + Act: Pass the array to the `sort` method for sorting. + Assert: Use `assertArrayEquals` to confirm the returned array matches the original array. +Validation: + A single-element array is already sorted by definition.
