closes #277

@perillo What does this error mean:

   +- RemoveDir /home/runner/work/ziglings/ziglings/zig-cache/tmp/cedb2d3eea8bc44c transitive failure
   |  +- check failure
   |     +- zig build -Dhealed success 1m MaxRSS:168M
   |        +- heal success
   |           +- case-2 cached

[chrboesch]

There is another hint:
check: error: 999_the_end.zig: expected to see "Compiling 999_the_end.zig...", found "PASSED:"

[chrboesch]

After the third run I get other errors:
zig build -Dhealed -Dn=94: error: the following command exited with code 2 (expected exited with code 0):

Weird.

[chrboesch]

Maybe it depends on #300

The cause is the new exercise 102, that confuses the CheckStep.
The solution is to update the tests.

Weird.

I can not reproduce it. Can you tell me the error message?

[chrboesch]

Just run zig build test or take a look at: https://github.com/ratfactor/ziglings/actions/runs/4974676427/jobs/8901548287#step:4:15

The solution is to update the tests.

I already updated the tests. But as you can see in the github actions, there is no error on 102: https://github.com/ratfactor/ziglings/actions/runs/4974676427/jobs/8901548287#step:4:325

[perillo]

@chrboesch I have fixed the problem. I will create a PR later (with some changes in how testing is implemented)

[chrboesch]

I will create a PR later

ok

The action log does not show the error
zig build -Dhealed -Dn=94: error: the following command exited with code 2 (expected exited with code 0):

and I was unable to reproduce it.
