Problem/Motivation
If your testing module produces the "Parse error" on the Drupal install stage, sometimes you don't see this error text in the Nightwatch output.
Steps to reproduce
1. Run a Nightwatch test from Core, eg this one:
yarn test:nightwatch /var/www/html/web/core/tests/Drupal/Nightwatch/Tests/loginTest.js
See that it executes well.
2. Open the file modules/user/src/UserFloodControl.php and make a syntax error there, eg like this:
class UserFloodControl implements UserFloodControlInterface {
asdsad
/**
3. Run the Nightwatch test again, and see that Drupal fails to install, but with no error output:
$ yarn test:nightwatch /var/www/html/web/core/tests/Drupal/Nightwatch/Tests/loginTest.js
yarn run v1.22.22
$ node -r dotenv-safe/config ./node_modules/.bin/nightwatch --config ./tests/Drupal/Nightwatch/nightwatch.conf.js /var/www/html/web/core/tests/Drupal/Nightwatch/Tests/loginTest.js

4. Run the install command manually in the console and see the actual error text:
$ php ./scripts/test-site.php install --install-profile "nightwatch_testing" --base-url http://web --db-url mysql://db:db@db/db --json
Xdebug: [Step Debug] Could not connect to debugging client. Tried: 127.0.0.1:9003 (fallback through xdebug.client_host/xdebug.client_port).
Parse error: syntax error, unexpected identifier "asdsad", expecting "function" or "const" in /var/www/html/web/core/modules/user/src/UserFloodControl.php on line 17
This happens because for some reason PHP outputs the error to stdout instead of the stderr.
Proposed resolution
When Drupal fails to install, output the stdout to the console as well.
Remaining tasks
User interface changes
Introduced terminology
API changes
Data model changes
