there is no need to use an altcoin that may be different or even have serious bugs that could give you false sense of correctness after you performed your test. instead you can easily use regtest mode of bitcoin core to acquire any amount of bitcoins in as many number of blocks as you like and spend them.
100 blocks take about 1.5 seconds to be generated on regtest due to its low defined difficulty.
follow this: https://bitcoin.org/en/developer-examples#regtest-mode
And your point too.
Which is why I said someone (or a group of us) should come together. Make a generic statement of why you are not getting 500 testnet coins and why you don't need them.
And when someone comes in and asks for them it's a copy-paste of the same statement. Eventually I would think people would get the message.
