- I can enter a sudoku puzzle by filling in the text area with either a number or period (.) to represent an empty cell.
- When a valid number is entered in the text area, the same number is applied to the correct cell of the sudoku grid.
- I can enter a sudoku puzzle by adding numbers directly to the sudoku grid.
- When a valid number is entered in the sudoku grid, the same number appears in the correct position in the text area.
- The text area should only update the corresponding sudoku grid cell when a whole number between 1 and 9 is entered.
- The sudoku grid should only update the puzzle string in the text area when a whole number between 1 and 9 is entered into a cell.
- I can solve an incomplete puzzle by clicking the "Solve" button. When a solution is found, the sudoku grid and text area are automatically populated with the correct numbers for each cell in the grid or position in the text area.
- This sudoku solver is not expected to be able to solve every incomplete puzzle. See
/public/puzzle-strings.jsfor a list of puzzle strings it should be able to solve along with their solutions. - If the puzzle is not 81 numbers or periods long, append the message "Error: Expected puzzle to be 81 characters long." to the
error-msgdivso the text appears in red. - I can clear the text area and sudoku grid by clicking the "Clear" button.
- All 6 unit tests are complete and passing. See
/tests/1_unit-tests.jsfor the expected behavior you should write tests for. - All 4 functional tests are complete and passing. See
/tests/2_functional-tests.jsfor the functionality you should write tests for.
- To run the tests on Repl.it, set NODE_ENV to test without quotes in the .env file.
- To run the tests in the console, use the command npm run test. To open the Repl.it console, press Ctrl+Shift+P (Cmd if on a Mac) and type "open shell".
- All logic can go into
