This commit applies `strictNullChecks` to the entire codebase to improve maintainability and type safety. Key changes include: - Remove some explicit null-checks where unnecessary. - Add necessary null-checks. - Refactor static factory functions for a more functional approach. - Improve some test names and contexts for better debugging. - Add unit tests for any additional logic introduced. - Refactor `createPositionFromRegexFullMatch` to its own function as the logic is reused. - Prefer `find` prefix on functions that may return `undefined` and `get` prefix for those that always return a value.

# Tests
|
|
|
|
There are different types of tests executed:
|
|
|
|
1. [Unit tests](#unit-tests)
|
|
2. [Integration tests](#integration-tests)
|
|
3. [End-to-end (E2E) tests](#e2e-tests)
|
|
4. [Automated checks](#automated-checks)
|
|
|
|
## Unit and integration tests
|
|
|
|
- They utilize [Vitest](https://vitest.dev/).
|
|
- Test files are suffixed with `.spec.ts`.
|
|
|
|
### Act, arrange, assert
|
|
|
|
- Tests implement the act, arrange, and assert (AAA) pattern.
|
|
- **Arrange**
|
|
- Sets up the test scenario and environment.
|
|
- Begins with comment line `// arrange`.
|
|
- **Act**
|
|
- Executes the actual test.
|
|
- Begins with comment line `// act`.
|
|
- **Assert**
|
|
- Sets an expectation for the test's outcome.
|
|
- Begins with comment line `// assert`.
|
|
|
|
### Unit tests
|
|
|
|
- Evaluate individual components in isolation.
|
|
- Located in [`./tests/unit`](./../tests/unit).
|
|
- Achieve isolation using [stubs](./../tests/unit/shared/Stubs).
|
|
- Include Vue component tests, enabled by `@vue/test-utils`.
|
|
|
|
#### Unit tests naming
|
|
|
|
- Test suites start with a description of the component or system under test.
|
|
- E.g., tests for `Application.ts` are contained in `Application.spec.ts`.
|
|
- Whenever possible, `describe` blocks group tests of the same function.
|
|
- E.g., tests for `run()` are inside `describe('run', () => ...)`.
|
|
|
|
### Integration tests
|
|
|
|
- Assess the combined functionality of components.
|
|
- They verify that third-party dependencies function as anticipated.
|
|
|
|
## E2E tests
|
|
|
|
- Examine the live web application's functionality and performance.
|
|
- Uses Cypress to run the tests.
|
|
|
|
## Automated checks
|
|
|
|
These checks validate various qualities like runtime execution, building process, security testing, etc.
|
|
|
|
- Use [various tools](./../package.json) and [scripts](./../scripts).
|
|
- Are automatically executed as [GitHub workflows](./../.github/workflows).
|
|
|
|
### Security checks
|
|
|
|
- [`checks.security.sast`](./../.github/workflows/checks.security.sast.yaml): Utilizes CodeQL to conduct Static Analysis Security Testing (SAST) to ensure the secure integrity of the codebase.
|
|
- [`checks.security.dependencies`](./../.github/workflows/checks.security.dependencies.yaml): Performs audits on third-party dependencies to identify and mitigate potential vulnerabilities, safeguarding the project from exploitable weaknesses.
|
|
|
|
## Tests structure
|
|
|
|
- [`package.json`](./../package.json): Defines test commands and includes tools used in tests.
|
|
- [`vite.config.ts`](./../vite.config.ts): Configures `vitest` for unit and integration tests.
|
|
- [`./src/`](./../src/): Contains the code subject to testing.
|
|
- [`./tests/shared/`](./../tests/shared/): Contains code shared by different test categories.
|
|
- [`bootstrap/setup.ts`](./../tests/shared/bootstrap/setup.ts): Initializes unit and integration tests.
|
|
- [`Assertions/`](./../tests/shared/Assertions/): Contains common assertion functions, prefixed with `expect`.
|
|
- [`./tests/unit/`](./../tests/unit/)
|
|
- Stores unit test code.
|
|
- The directory structure mirrors [`./src/`](./../src).
|
|
- E.g., tests for [`./src/application/ApplicationFactory.ts`](./../src/application/ApplicationFactory.ts) reside in [`./tests/unit/application/ApplicationFactory.spec.ts`](./../tests/unit/application/ApplicationFactory.spec.ts).
|
|
- [`shared/`](./../tests/unit/shared/)
|
|
- Contains shared unit test functionalities.
|
|
- [`TestCases/`](./../tests/unit/shared/TestCases/)
|
|
- Shared test cases.
|
|
- Functions that calls `it()` from [Vitest](https://vitest.dev/) should have `it` prefix.
|
|
- [`Stubs/`](./../tests/unit/shared/Stubs): Maintains stubs for component isolation, equipped with basic functionalities and, when necessary, spying or mocking capabilities.
|
|
- [`./tests/integration/`](./../tests/integration/): Contains integration test files.
|
|
- [`cypress.config.ts`](./../cypress.config.ts): Cypress (E2E tests) configuration file.
|
|
- [`./tests/e2e/`](./../tests/e2e/): Base Cypress folder, includes tests with `.cy.ts` extension.
|
|
- [`/support/e2e.ts`](./../tests/e2e/support/e2e.ts): Support file, runs before every single spec file.
|
|
- [`/tsconfig.json`]: TypeScript configuration for file Cypress code, improves IDE support, recommended to have by official documentation.
|
|
- *(git ignored)* `/videos`: Asset folder for videos taken during tests.
|
|
- *(git ignored)* `/screenshots`: Asset folder for Screenshots taken during tests.
