- All puzzle logic can go into /controllers/sudoku-solver.js
- The validate function should take a given puzzle string and check it to see if it has 81 valid characters for the input.
- The check functions should be validating against the current state of the board.
- The solve function should handle solving any given valid puzzle string, not just the test inputs and solutions. You are expected to write out the logic to solve this.
- All routing logic can go into /routes/api.js
- See the puzzle-strings.js file in /controllers for some sample puzzles your application should solve
- To run the challenge tests on this page, 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"
- A very basic template for the manual test cases is in the file /tests/myTestCaseTemplate.ods.
- Postman functional tests are in the files /tests/Solve Suite.postman_collection.json and /tests/Check Placement Suite.postman_collection.json.
- Postman test results are in the files /tests/Solve Suite.postman_test_run.json and /tests/Check Placement Suite.postman_test_run.json.
Write the following tests in tests/1_unit-tests.js:
- Logic handles a valid puzzle string of 81 characters
- Logic handles a puzzle string with invalid characters (not 1-9 or .)
- Logic handles a puzzle string that is not 81 characters in length
- Logic handles a valid row placement
- Logic handles an invalid row placement
- Logic handles a valid column placement
- Logic handles an invalid column placement
- Logic handles a valid region (3x3 grid) placement
- Logic handles an invalid region (3x3 grid) placement
- Valid puzzle strings pass the solver
- Invalid puzzle strings fail the solver
- Solver returns the the expected solution for an incomplete puzzle
Write the following tests in tests/2_functional-tests.js
