I am applying for a job, but they don't ask for Cover Letter. Should I include a cover letter anyway. If I was on the hiring end, I would look straight at the applicant's resume, and if I am interested, invite them for interview.
I use the resume as a general purpose document. I customize the cover letter to specifically state in what ways my work experience and skills set fit the prospective employer's requirements.
The alternative to writing a good cover letter would be for me to create a different resume for each position I am applying for, and I am not about to drive myself crazy doing that.
You can send your resume as-is without a cover letter but if I were the recipient, I'd throw your resume in the trash. I'd figure that if you won't take the time to make the argument as to why you are a good candidate, I don't have to make the time to read your resume either. I am not about to squint through your resume and make for you your argument as to why we should see you for an interview.

Unless you are applying through a forms-based website that prevents attaching a cover letter, or unless the job posting specifically mentions "no cover letters", then Yes - include a cover letter anyway.
A cover letter lets you expand on your fit for the position. It's less structured than a resume, and allows you to highlight specific areas that make you a great candidate for that specific job, in that specific company.
It makes sense to put some extra effort into your attempt to land a good job. Write a cover letter specifically for each individual application. Include it whenever you can.
A good resume is like seeing that a smartphone has a 4GHz processor and 8GB of RAM. A good cover is letter is like seeing the first cell phone or smartphone...seeing those pieces in action to spark a narrative in your head that can excite you about concrete possibilities. It's good to have the second ready to follow up if not to lead in.
More formally...Transition Cases:
Converting "Resume and Cover Letter" to "Resume" = when closing thumb and forefinger to grip paper, do not catch front page between fingers.
Converting "Resume" to "Resume and Cover Letter" = look up contact info, contact person, express what you want, wait some time, return to communication medium, download item, open item.
Option #1 puts them in an easy position to correct to the state they want.
No, don't provide a boilerplate cover letter unless there is something you truly need to share. Not all positions are special snowflakes, a good part of openings can be sufficiently covered by a well-written generic resume.
As of 2018, more and more recruiters are making the cover letter optional and in my opinion they recognize that in some cases it's just a noise, making life just a bit harder for both the candidate and for the recruiter.
Nowadays these positions that explicitly require cover letters have an obligatory field in their online application form; these where it's optional have an optional field. No field? Assume they probably don't need a (boilerplate) cover letter.
If you need to share thoughts that are specific to your fit for that job/company, I am sure every recruiter will be happy to read your letter.
