## Introduction
End-to-End (E2E) testing verifies that the application functions correctly from a user's perspective by testing the complete application workflow. This document outlines the E2E testing approach for the Home Monitor application.
### Goals of E2E Testing
- Validate critical user flows function correctly
- Ensure components work together as expected
- Detect regression issues before production deployment
- Verify application behavior in real-world scenarios
## Testing Strategy
Home Monitor uses Cypress for E2E testing with two primary approaches:
1. **Mock Testing (Without Server)**: Fast, reliable tests using mocked DOM elements and data
2. **Real Environment Testing (With Server)**: Full application testing with a running development server
### Mock vs. Real Testing Comparison
| Aspect | Mock Testing | Real Environment Testing |
|--------|-------------|--------------------------|
| Speed | Very fast (< 1s per test) | Slower (depends on app loading time) |
| Reliability | Highly stable | May be affected by server/network issues |
| Coverage | Limited to structure and basic interactions | Tests actual rendering and behaviors |
| Dependencies | None (no server needed) | Requires development server |
| Best for | CI/CD, quick verification | Final validation, regression testing |
## Test Environment Setup
### Prerequisites
- Node.js (v14+)
- npm or yarn
- Chrome browser (for visual testing)
### Installation
```bash
# Install dependencies
cd project-softweng/web-app
npm install
```
## Running Tests
### Option 1: Tests with Mock Environment (No Server)
```bash
# Run all tests in headless mode
export CYPRESS_SKIP_SERVER_CHECK=true
npm run test:e2e
# Run specific test file
export CYPRESS_SKIP_SERVER_CHECK=true
npx cypress run --spec "tests/e2e/app.spec.ts"
```
### Option 2: Tests with Real Application (Server Required)
#### Automated Script Method
```bash
# Use the automated script (starts server, runs tests, stops server)
./tests/e2e/run-e2e-tests.sh
```
#### Manual Method
1. Start the development server:
```bash
# Terminal 1
npm run serve
```
2. Run the tests:
```bash
# Terminal 2
# Headless mode
npx cypress run --spec "tests/e2e/app.spec.ts"
# Interactive mode
npx cypress open
```
### Interactive Mode (Development)
```bash
npm run cypress:open
```
This opens the Cypress Test Runner where you can:
- Select individual tests to run
- See test execution in real-time
- Debug failing tests with time-travel debugging
## Test Structure
### Directory Structure
```
web-app/
├── tests/
│ ├── e2e/ # E2E test files
│ │ ├── app.spec.ts # Main application tests
│ │ └── run-e2e-tests.sh # Script for running tests with server
│ └── support/ # Support files
│ ├── commands.ts # Custom Cypress commands
│ └── e2e.ts # Global setup for E2E tests
└── cypress.config.ts # Cypress configuration
```
### Test Files Organization
Each test file follows this structure:
1. **Setup**: Import dependencies and set up the test environment
2. **Beforehooks**: Prepare the application state before each test
3. **Test Cases**: Individual test scenarios grouped by feature
4. **Helper Functions**: Support functions for test cases
## Test Cases Overview
The E2E test suite covers the following scenarios:
1. **Application Loading**
- Verify application loads with correct title
- Confirm main layout sections are visible
2. **Control Panel Functionality**
- Verify control panel buttons are present
- Test "Fetch Measurements" button works
- Test "New Measurements" button works
3. **Filtering Controls**
- Test user selection dropdown
- Test room selection dropdown
- Test device selection dropdown
4. **Data Visualization**
- Verify chart displays correctly
- Test chart updates when data changes
5. **Error Handling**
- Test error state display
- Test empty data state display
6. **Responsive Design**
- Verify layout adapts to desktop viewport
- Verify layout adapts to mobile viewport
## Writing New Tests
### Adding a New Test Case
1. Identify the feature or flow to test
2. Determine the expected behavior
3. Add a new test case to the appropriate spec file:
```typescript
it('should [describe expected behavior]', () => {
// Setup any preconditions
// Perform actions
// Assert expected outcomes
});
```
### Custom Commands
Custom commands are available to simplify test writing:
```typescript
// Select an option from a multiselect dropdown
cy.selectMultiselectOption('user-select', 'user1');
// Wait for chart to load and be visible
cy.waitForChart();
// Check application loading state
cy.checkLoadingState(false);
```
### API Mocking
Use Cypress's intercept feature to mock API responses:
```typescript
// Mock GET request
cy.intercept('GET', '**/api/measurements*', {
statusCode: 200,
body: {
data: [
{ time: new Date(2023, 0, 1, 10, 0).getTime(), value: 22.5, type: 'temperature' }
]
}
}).as('getMeasurements');
// Wait for the intercepted request
cy.wait('@getMeasurements');
```
## Best Practices
1. **Test Independence**
- Each test should be able to run independently
- Avoid dependencies between tests
- Reset state between tests
2. **Selector Strategy**
- Prefer data attributes for test selectors (e.g., `data-cy`, `data-testid`)
- Avoid using CSS classes that might change with styling updates
- Establish a consistent selector naming convention
3. **Handling Asynchronous Operations**
- Use explicit waits rather than arbitrary timeouts
- Wait for specific elements or network requests rather than fixed delays
- Handle loading states appropriately
4. **Test Data Management**
- Use consistent test data
- Mock external dependencies
- Consider using fixtures for complex data structures
5. **Error Handling**
- Add proper error handling in tests
- Use `Cypress.on('uncaught:exception')` for expected application errors
## Troubleshooting
### Common Issues and Solutions
| Issue | Solution |
|-------|----------|
| Tests fail with 401 errors | Add `Cypress.on('uncaught:exception', () => false)` to handle authentication errors |
| Elements not found | Increase timeouts or check selectors; ensure elements are in the DOM |
| Click actions failing | Use `{ force: true }` option if elements might be covered by overlays |
| Tests passing locally but failing in CI | Check environment differences; ensure CI has all required dependencies |
| Timeouts on waiting for elements | Increase `defaultCommandTimeout` in cypress.config.ts |
### Debugging Strategies
1. **Use Cypress's Debug Tools**
- Add `.debug()` to pause execution at a specific point
- Use the time-travel debugger in interactive mode
2. **Add Logging**
- Use `cy.log()` to add informative messages in the test
- Check browser console for application errors
3. **Visualize Test State**
- Enable screenshots and videos for failed tests
- Use `cy.screenshot()` at critical points

# Test Documentation
This document describes the automated tests implemented for the Home Monitor project. The tests are written with Cypress and are organized into two distinct categories: unit tests and end-to-end (E2E) tests.
## Test Types and Structure
The tests are organized in separate folders according to their type:
### 1. Unit Tests (`tests/unit/`)
Unit tests focus on testing individual components or classes in isolation, without dependencies on other parts of the system.
- **Example**: `Serie.spec.ts` - Tests the `Serie` class methods and functionality in isolation
- **Purpose**: Verify that individual components work correctly on their own
- **Characteristics**: Fast, focused, and test a single unit of code
### 2. End-to-End Tests (`tests/e2e/`)
E2E tests simulate real user scenarios by testing the entire application flow from start to finish.
- **Example**: `app.spec.ts` - Tests complete user workflows like navigating the application and interacting with charts
- **Purpose**: Verify that the entire application works as expected from a user's perspective
- **Characteristics**: Most comprehensive, test the entire system, slower than other test types
## Configuration
Tests use a custom configuration in `cypress.unit.js` that allows different test types to run with appropriate settings. Key features:
- Unit tests run without isolation (can share context)
- E2E tests run with isolation (fresh environment for each test)
- All tests can run without requiring a server (baseUrl is set to null)
- Optimized settings for performance (no videos, screenshots disabled by default)
## Running Tests
### Running Specific Test Types
```bash
# Run unit tests
npm run test:unit
# Run E2E tests
npm run test:e2e
```
### Running All Tests
```bash
npm run test
```
### Using Cypress GUI
To run tests through the Cypress graphical interface:
```bash
npm run cypress:open
```
This method is particularly useful during development, as it allows you to:
- View tests in real-time
- Inspect DOM elements
- Replay individual tests
- See a detailed overview of the executed steps
## Detailed Test Examples
### Unit Tests for Serie Class
The unit tests (`tests/unit/Serie.spec.ts`) verify that the Serie class works correctly in isolation:
- **Initialization**: Tests that the class initializes with the correct properties
- **Label Generation**: Tests that the `getLabel()` method returns the correct label based on series type
- **Data Formatting**: Tests that the `getSerie()` method correctly formats data for the chart library
### E2E Tests for Application
The E2E tests (`tests/e2e/app.spec.ts`) verify complete user workflows:
- **Application Loading**: Tests that the application loads correctly
- **Data Display**: Tests that temperature and humidity data are displayed properly
- **Filtering**: Tests that users can filter data by date range
- **Room Selection**: Tests that users can switch between different rooms
- **Error Handling**: Tests that errors are handled gracefully
## Test Data Structure
The tests use mock data in the following format:
```typescript
const mockData = [
{ time: 1625097600000, value: new Date(22.5) },
{ time: 1625184000000, value: new Date(23.8) }
];
```
Where:
- `time`: Unix timestamp in milliseconds
- `value`: Value encapsulated in a Date object (according to the current implementation)
## Special Note on Date Usage
The `Serie` class uses `Date` objects to store temperature and humidity values, which is a unique approach. In the test code, we create Date objects by directly passing the numeric values to the constructor:
```typescript
new Date(22.5) // For a temperature of 22.5°C
new Date(45) // For a humidity of 45%
```
This approach is specific to the current implementation of the `Serie` class and might be modified in the future to directly use numeric values.
## Best Practices
## Test Organization
1. **Test Hierarchy**:
- Unit tests -> E2E tests
- Tests should get progressively more comprehensive
- Most of your tests should be unit tests (faster and more focused)
2. **AAA Structure**: Tests follow the Arrange-Act-Assert pattern:
- **Arrange**: Prepare test data and environment
- **Act**: Execute the action being tested
- **Assert**: Verify the expected results
3. **Isolation**: Each test should be independent and not depend on shared state
### Test Troubleshooting
If tests fail, check the following:
1. **Server Issues**: If you're running E2E tests that require a server, make sure it's started on the appropriate port
2. **API Changes**: If the classes or components are modified, tests must be updated accordingly
3. **Synchronization Issues**: Cypress might need additional time for certain operations
4. **Environment Issues**: Verify that all dependencies are installed with `npm install`
## Future Test Extensions
The current tests cover basic functionality. In the future, it would be useful to add:
1. More unit tests for all components and services
2. More comprehensive E2E tests covering all user scenarios
3. Performance tests for operations on large data sets
