< h1 > Flutter Integration Test Server in Debian 11 Nspawn Container< / h1 >
< p > date: 2021-09-24< / p >
< h2 id = "introduction" > Introduction< / h2 >
< h3 id = "performance" > Performance< / h3 >
< p > Your Debian Server is way more powerful than your laptop or desktop
and flutter integration_tests suck.< / p >
< h3 id = "ergonomics" > Ergonomics< / h3 >
< p > You have an Android Emulator (or a real device) connected to the machine
that you are sitting in front of for reference, and now you can run
integration_tests on a different device without having to juggle adb
connections on the same machine.< / p >
< h3 id = "nspawn-tho" > Nspawn Tho?< / h3 >
< p > Because containers unlike virtual machines access the full power of the
host, but nspawn containers are peristent like virtual machines, sparing
you the cognitive overhead of dealing with the ephemerality of docker
containers and/or of herding cats.< / p >
< p > And you already have nspawn, it's build into systemd. Even including the
(virtual) network interfaces.< / p >
< h3 id = "documentation" > Documentation< / h3 >
< p > Let's face it: setting up an Android Development Environment is a nightmare.< / p >
< p > So don't just follow this guide; follow this guide a repetition of three
2021-09-25 06:57:05 -07:00
times, building your own step-by-step guide for yourself as you go. Your brain
2021-09-25 06:47:14 -07:00
