test-files-indentation.s
Standardizing the indentation of a test file saves the developer 30 seconds per new function to test.
There are 2 cases:
Use the following indentation even if only one function is tested:
- 1
describeper file- 1
describeper function - 1
itfor each case
Use the following indentation:
- 1
describewith the name of the file- 1
itfor each functionality
describe('Name of the tested file', () => {
describe('function1', () => {
it('does something', () => {
//...
});
it('does some other thing', () => {
//...
});
});
describe('function2', () => {
it('does something', () => {
//...
});
it('does some other thing', () => {
//...
});
});
});
