You will get a hardline answer for me. In the 90’s I worked as a contract programmer for Bayer Diagnostics which is now owned by Siemens. You probably know of them or Colter for their blood machines that count rbc, wbc and neutxy.
Phase 1 was for human blood and Phase II was multi-species. I was brought into help with phase 1 which was very behind schedule for a 3 month contract which ended up lasting 3 years. After releasing 1000 machines, Phase 2 was being developed in Dublin. It was pretty much the same software with a small calculation adjustment and a dial for animals added. This was developed by our Dublin team while I was in New York.
It did not occur to me that the multi-species machine would be used for animal laboratory testing until a fellow vegetarian told me about the very low or negligible amount of animals that would be allocated for vetanary use. I spoke to my manager and he convinced me to stay because the code base was separated into two projects. Although my code was used for the Phase II machine, it was hand copied by the manager to the project from the Human machine. However, eventually I quit because I refused to help with the phase II machine that was already in testing (in New York).
When the chief of testing would come in to my office asking for help about a bug they found, I leaned back in my chair and ask if it was the human machine or animal machine. The head of testing was really angry at that, and although my manager backed me up, I decided to leave. I gave 6 months notice and started my trip around the world and eventually became a monk.
That was in early 1999, when gas was $1.20 per/gal “for the good stuff”, and I was making $81 per hour. I’m so glad I quit my job because that now defines who I am today.
I always tell people, when your sīla gets in the way of work and you cannot hold a job anymore because of dhamma, then it is time to ordain. So when will you visit Sri Lanka and other Theravāda countries 
I should add that Bayer was a chemical company. The chemicals for testing blood were similar to printer inks, and the $70,000 usd machine was “given away at cost” to cause chemical sales… While human blood needs a doctor’s order, animal blood was the big money winner because the sky was the limit for how many animals that can be tested (and harmed or killed in the process). If you did not pay $250 for 2 gallons of soapy salty water, the machine would not be certified. I’m sure you know all about this as a tester. I’m glad you posted this question. It makes the reality of why I quit my job all more real.
My advice is not to do the slightest wrong…ever.
