tests/data/cypress/src/reporter-config.json (1)
1-6: Fix indentation inconsistencyThe configuration is well-structured, but the indentation is inconsistent (4 spaces vs 2 spaces).
Apply this diff to maintain consistent 2-space indentation:
{ - "reporterEnabled": "spec, mocha-junit-reporter", - "mochaJunitReporterReporterOptions": { - "mochaFile": "cypress/results/results-[hash].xml" - } - } + "reporterEnabled": "spec, mocha-junit-reporter", + "mochaJunitReporterReporterOptions": { + "mochaFile": "cypress/results/results-[hash].xml" + } +}tests/data/cypress/src/cypress.config.js (3)
5-7: Consider implementing the setupNodeEvents functionThe
setupNodeEventsfunction is currently empty with just a placeholder comment. This function is crucial for tasks like:
- Handling test failures
- Setting up custom tasks
- Configuring screenshots/videos
- Implementing custom commands
Here's a basic implementation example:
setupNodeEvents(on, config) { - // implement node event listeners here + on('task', { + log(message) { + console.log(message) + return null + } + }) + on('after:spec', (spec, results) => { + if (results && results.stats.failures) { + console.error(`'${spec.name}' failed`) + } + }) },
3-14: Consider adding essential Cypress configurationsThe current configuration is minimal. Consider adding commonly needed configurations for robust E2E testing:
Here's a suggested enhancement:
module.exports = defineConfig({ e2e: { setupNodeEvents(on, config) { // ... event implementations }, + baseUrl: 'http://localhost:3000', + viewportWidth: 1280, + viewportHeight: 720, + defaultCommandTimeout: 5000, + video: false, // Disable video recording by default + screenshotOnRunFailure: true, + specPattern: 'cypress/e2e/**/*.cy.{js,jsx,ts,tsx}', }, reporter: 'junit', reporterOptions: { mochaFile: 'tests/data/cypress/test-result.xml', toConsole: true, }, + retries: { + runMode: 2, + openMode: 0 + } });
1-14: Consider migrating to TypeScriptThe configuration is currently in JavaScript. Given that this appears to be a new test setup, consider using TypeScript for better type safety and IDE support.
Steps to migrate:
- Rename file to
cypress.config.ts- Update the import:
- const { defineConfig } = require("cypress"); + import { defineConfig } from "cypress";
- Add
tsconfig.jsonfor Cypress:{ "compilerOptions": { "target": "es5", "lib": ["es5", "dom"], "types": ["cypress", "node"], "strict": true }, "include": ["**/*.ts"] }tests/data/cypress/test-result.xml (2)
3-4: Remove empty test suiteThe "Root Suite" contains no tests and should be removed to maintain clean test results.
- <testsuite name="Root Suite" timestamp="2024-11-14T06:04:40" tests="0" file="cypress/e2e/1-getting-started/todo.cy.js" time="0.000" failures="0"> - </testsuite>
13-19: Improve test naming consistencyWhile the test coverage is good, consider improving the naming structure:
- Remove redundant prefixes ("example to-do app") from test names
- Make classnames consistent with test names
- <testcase name="example to-do app with a checked task can filter for uncompleted tasks" time="0.216" classname="can filter for uncompleted tasks"> + <testcase name="can filter for uncompleted tasks" time="0.216" classname="with a checked task - can filter for uncompleted tasks">tests/data/cypress/record_test_result.json (2)
Line range hint
6-81: Well-structured test suite with comprehensive coverageThe test suite demonstrates good practices:
- Clear, descriptive test names that follow a consistent pattern
- Comprehensive coverage of core todo functionality:
- Default item display
- Task completion
- Filtering (both completed and uncompleted)
- Deletion of completed tasks
- Reasonable test execution times (0.15-0.22s) for passing tests
However, consider adding tests for:
- Adding new todo items
- Editing existing items
- Edge cases (empty list, maximum items)
Line range hint
29-77: Consider adding performance thresholds for test durationsThe passing tests show consistent execution times:
- Check off item: 0.151s
- Filter uncompleted: 0.216s
- Filter completed: 0.213s
- Delete completed: 0.209s
Consider adding performance assertions to ensure tests maintain acceptable execution times as the application grows.
Example configuration in
cypress.config.js:{ e2e: { performanceThreshold: { maxDuration: 300 // maximum allowed duration in milliseconds } } }tests/data/cypress/src/cypress/e2e/1-getting-started/todo.cy.js (2)
3-13: Consider streamlining the introductory comments.While documentation is valuable, consider condensing these comments to focus on test-specific information rather than general Cypress introduction. The link to Cypress documentation could be moved to the README file.
14-143: Consider adding test coverage for edge cases and accessibility.While the current test suite covers the main functionality, consider adding:
- Negative test cases (e.g., empty todo items, very long text)
- Accessibility tests using
cypress-axe- Keyboard navigation tests
Example accessibility test:
it('should have no accessibility violations', () => { cy.injectAxe() cy.checkA11y() })🧰 Tools

Investigate failing test: Element count mismatch
The test "displays two todo items by default" is failing due to a mismatch in the number of todo items:
- Expected: 3 items
- Found: 2 items
- Test is timing out after 4000ms
This could indicate:
- A race condition (test timing out)
- Incorrect test expectations
- A regression in the application's default items
Let's verify the expected number of default items:

Failed Test: Investigate assertion timeout in default todo items test
The test displays two todo items by default is failing with the following error:
AssertionError: Timed out retrying after 4000ms: Not enough elements found. Found '2', expected '3'.
This indicates a mismatch between the expected number of default todo items (3) and the actual number found (2).
Please verify:
- The initial state setup in your test fixtures
- The actual implementation of default todo items
- Whether the timeout duration (4000ms) is sufficient for the page to load completely

🛠️ Refactor suggestion
Use absolute path for mochaFile
Using a relative path ('../test-result.xml') for mochaFile could be fragile as it depends on the working directory when Cypress is executed.
Consider using an absolute path:
- mochaFile: '../test-result.xml',
+ mochaFile: 'tests/data/cypress/test-result.xml',📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

💡 Codebase verification
Missing cypress-junit-reporter dependency
The configuration uses the 'junit' reporter, but the required cypress-junit-reporter package is not listed in the dependencies. Add the following to devDependencies:
"cypress-junit-reporter": "^1.0.0"🔗 Analysis chain
Verify reporter dependencies
The configuration specifies 'junit' reporter, but we need to verify if the required dependencies are installed.

Test suite contains failing and skipped tests
The test results show 1 failing test and 1 skipped test out of 6 total tests. This needs attention as:
- Failing tests should be fixed before merging
- Skipped tests should be either enabled or removed to maintain a clean test suite

🛠️ Refactor suggestion
Replace hardcoded URL with environment configuration.
Using a hardcoded URL makes the tests environment-dependent and less maintainable. Consider using Cypress environment variables or configuration files to manage the base URL.
- cy.visit('https://example.cypress.io/todo')
+ cy.visit(Cypress.env('BASE_URL') + '/todo')Also, add the following to your cypress.config.js:
module.exports = {
env: {
BASE_URL: process.env.TEST_URL || 'http://localhost:3000'
}
}| context('with a checked task', () => { | ||
| beforeEach(() => { | ||
| // We'll take the command we used above to check off an element | ||
| // Since we want to perform multiple tests that start with checking | ||
| // one element, we put it in the beforeEach hook | ||
| // so that it runs at the start of every test. | ||

| }) |

🛠️ Refactor suggestion
Refactor duplicate beforeEach setup into a custom command.
The duplicate beforeEach hook violates DRY principles and was flagged by static analysis. Consider moving the checkbox checking logic into a custom Cypress command.
Add this to your cypress/support/commands.js:
Cypress.Commands.add('checkTodoItem', (text) => {
cy.contains(text)
.parent()
.find('input[type=checkbox]')
.check()
})Then update the tests:
- beforeEach(() => {
- cy.contains('Pay electric bill')
- .parent()
- .find('input[type=checkbox]')
- .check()
- })
+ beforeEach(() => {
+ cy.checkTodoItem('Pay electric bill')
+ })🧰 Tools

Fix inconsistency in test description and assertion.
The test description states "displays two todo items by default" but the assertion checks for 3 items. Update either the test description or the assertion to maintain consistency.

2-2: Previous comment about failing and skipped tests is still applicable
3-3: LGTM! Root suite structure is correct
13-18: Well-structured test cases with good coverage
The test suite demonstrates good practices:
- Clear, descriptive test names
- Logical grouping of related test cases
- Comprehensive coverage of filtering and deletion functionality
6-8: Verify the expected number of default todo items
The test is failing because it expects 3 todo items but finds only 2. This could indicate:
- A regression in the application's initialization logic
- Or incorrect test expectations
tests/data/cypress/src/cypress/e2e/1-getting-started/todo.cy.js (4)
60-80: LGTM! Well-structured test with clear documentation.
The test effectively validates the completion functionality with appropriate DOM traversal and assertions.
94-122: LGTM! Comprehensive filter tests.
The filter tests effectively validate both completed and uncompleted task views with appropriate assertions.
124-141: LGTM! Well-implemented cleanup test.
The test for deleting completed tasks is thorough and includes validation of the clear button's existence and proper cleanup.
33-34: Verify the last todo item assertion.
The test checks for 3 items but only verifies the first and last items. There seems to be a middle item that's not being verified. Consider adding an assertion for the middle item to ensure complete validation.
