welcome to SQA StackExchange!
The great thing about QA (please avoid the term 'tester', especially in interviews) is that it requires a broad range of personalities with a broad range of backgrounds. There is no single silver bullet training or personality that will discover all of the issues found within software. Honestly, some of the best people whom I have worked in within the QA field had no particular background or formal training in QA (As a matter of fact, I don't either).
So, how do you get into it? Well, your boyfriend would be a good start to begin with. He can likely at least get you an interview. The question then becomes how do you translate your interview into a job.
- Show that YOU took the initiative and learned about QA (which you are doing now). Learn the different aspects of manual testing, testing utilities and what have you. Learn some basic concepts and while not an absolute requirement something that is extremely beneficial will be SQL. There is several posts here regarding different training materials. I would focus on manual and avoid automation unless you have development history.
- Review interview questions for QA. Don't do this expecting the interviewer to ask those exact questions but more to see if you are a solid fit for the field. I will post a few as an example:
If you were tasked with testing a Red light at an intersection how would you perform this?
If you were tasked with testing that when a customer orders 12 items it recommends a dozen pack how would you test this?
When tasked with testing a piece of software with vague requirements, how would you handle this?
The first 2 are designed to see what your thought process is. Do you think of the edge cases, the factors that are not directly related to the task (IE, the crosswalk signal that is connected to the red light). The third is, sadly, seeing how well you would handle and how you would react to what is real world daily events at a majority of locations.
- Understand why you are wanting to get into QA. Interviewers can tell when someone is feeling pressured into something versus when it is their passion. If you are passionate about it you will likely be nervous, calm and excited all at once.
Overall though, at the end of the day, the question is why do you think you would be good for a QA department? There is no particular certificate, degree or experience that is required. Put in applications, contact recruiters and study up as much as possible. A lot of interviewers will respect that you, in your personal spare time, learned this.
