Disallow tests without assertions

Ensure that there no tests without assertions. Tests without assertions do not explicitly test something.

Rule Details

Examples of incorrect code for this rule:

describe('test suite', () => {
    it('should assert something', () => {
        doSomething();
        expect(true).to.equal(true);
    });
    it('should assert something else', () => {
        doSomething();
    });
});
describe('test suite', () => {
    test('should assert something', () => {
        doSomething();
    });
});

Examples of correct code for this rule:

describe('test suite', () => {
    it('should assert something', () => {
        expect(true).to.equal(true);
    });
    it('should assert something', () => {
        expect(true).to.equal(true);
    });
});

describe('test suite', () => {
    test('should assert something', () => {
        expectAsync(true).to.equal(true);
    });
});

describe('test suite', () => {
    test('should assert something', () => {
        assert(true).to.equal(true);
    });
});

Options

The assertCommands array contains the assert function names to match on. This will override the defaults.
