Common Prefixes:
* test: A very basic and widely used prefix.
* t: Short and concise, commonly used in frameworks like Jest.
* spec: Indicates a specification-style test, popular in frameworks like Jasmine.
* unit: For unit tests, which test individual components or functions.
* integration: For tests that verify the interaction between multiple components.
* e2e: Short for "end-to-end" tests, which cover the entire system from start to finish.
* smoke: For basic sanity checks that ensure the system is running.
* functional: For tests that verify the functionality of the system.
Example:
```javascript
// Jest examples:
test('should add two numbers', () => { ... });
it('should return a string', () => { ... });
// Mocha examples:
describe('MyComponent', () => {
it('should render correctly', () => { ... });
});
// Jasmine examples:
describe('MyComponent', () => {
it('should render correctly', () => { ... });
});
```
Best Practices:
* Consistency: Choose a prefix and stick with it throughout your project.
* Readability: The prefix should be short and meaningful, making it easy to identify the type of test at a glance.
* Framework Conventions: Follow the conventions of your chosen testing framework.
* Team Agreement: Discuss with your team and agree on a standardized prefix that everyone will use.
Ultimately, the most important thing is to choose a prefix that is clear, consistent, and helps improve the readability and maintainability of your test code.
