Faber demo: compile, run and test code in a sandbox

main.c GCC 12 · compile cached between runs

Tests

One build, then 4 runs in parallel, each with its own input.

1

Test 1 Input 1 2 3

Test 1 Expected output 6
2

Test 2 Input 40 2

Test 2 Expected output 42
3

Test 3 Input -7 7 100 1000

Test 3 Expected output 1100
4

Test 4 Input

Test 4 Expected output 0

C starter

Reads integers from stdin and prints their sum. Every test passes. Run it to compile it and test it inside a Faber sandbox.

The body this demo posts to /api/v1/execute for the program on screen: a build step marked cache: true, then every test as one parallel step. stop_on_failure skips the tests when the build fails.
