use-call-count-test-assert.md

Enforce using assert.equal(...callCount, ...); instead of assert.ok(...calledOnce); (square/use-call-count-test-assert)

💼 This rule is enabled in the following configs: 🔥 ember, 🔒 strict.

🔧 This rule is automatically fixable by the --fix CLI option.

Using callCount rather than the other shortcut count helpers (such as calledOnce, notCalled) allows the test runner to show the actual number of times the spy was called.

Rule Details

This lint rule prevents the use of:

• notCalled
• calledOnce
• calledTwice
• calledThrice
• called

The above do not provide as much information to the test runner.

Examples

Examples of incorrect code for this rule:

test('it works', function (assert) {
  assert.ok(this.spy.calledOnce);
});

Examples of correct code for this rule:

test('it works', function (assert) {
  assert.equal(this.spy.callCount, 1);
});
