A slow development test cycle will kill your software.
🔗
New developers won't want to learn your project, because they would rather shoot themselves.
🔗
This means that build time, and the time to run tests, must be short.
🔗
5 seconds to rebuild is the maximum upper limit.
🔗
You also have to spend some time profiling execution and build from scratch times.
🔗
A slow build from scratch will mean that your continuous integration costs a lot, money that could be invested in a new developer!
🔗
It also means that people won't bother to reproduce bugs on given commits, or bisect stuff.
🔗
One anecdote comes to mind. Ciro Santilli was trying to debug something, and more experience colleague came over.
🔗
Ciro was running one command, wait 5 seconds, run a second command, wait 5 seconds, run a third command:
cmd1
# wait
cmd2
# wait
cmd3
🔗
The first thing the colleague said: join those three commands into one:
cmd1;cmd2;cmd3
