mocha-steps

Sequential scenarios for Mocha

Global step() function, as a drop-in replacement for it(). Any failing step will abort the parent describe immediately. This is handy for BDD-like scenarios, or smoke tests that need to run through specific steps.

Setup

npm install mocha-steps --save-dev

Then simply run mocha with --require mocha-steps.

Example

describe('my smoke test', function() {

  step('login', function() {
  });

  step('buy an item', function() {
    throw new Error('failed');
  });

  step('check my balance', function() {
  });

  xstep('temporarily ignored', function() {
  });

});

• With the standard it()

my smoke test
   ✓ login
   ✗ buy an item
   ✓ check my balance
   - temporarily ignored

• Using step()

my smoke test
   ✓ login
   ✗ buy an item
   - check my balance
   - temporarily ignored

Notes

• Unlike Mocha's --bail option, the rest of the test suite will run normally.
• step() works with synchronous, async, event-based and promise tests.

When submitting a PR, please run ./test.sh and implement new test cases if required.
