Disallow Jasmine globals (no-jasmine-globals)

💼 This rule is enabled in the ✅ recommended config.

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

jest uses jasmine as a test runner. A side effect of this is that both a jasmine object, and some jasmine-specific globals, are exposed to the test environment. Most functionality offered by Jasmine has been ported to Jest, and the Jasmine globals will stop working in the future. Developers should therefore migrate to Jest's documented API instead of relying on the undocumented Jasmine API.

Rule details

This rule reports on any usage of Jasmine globals, which is not ported to Jest, and suggests alternatives from Jest's own API.

Examples

The following patterns are considered warnings:

jasmine.DEFAULT_TIMEOUT_INTERVAL = 5000;

test('my test', () => {
  pending();
});

test('my test', () => {
  fail();
});

test('my test', () => {
  spyOn(some, 'object');
});

test('my test', () => {
  jasmine.createSpy();
});

test('my test', () => {
  expect('foo').toEqual(jasmine.anything());
});

The following patterns would not be considered warnings:

jest.setTimeout(5000);

test('my test', () => {
  jest.spyOn(some, 'object');
});

test('my test', () => {
  jest.fn();
});

test('my test', () => {
  expect('foo').toEqual(expect.anything());
});
