Drupal Quality Control & Assurance 5

Question 1

What is the role of a 'test fixture' in Drupal automated testing?

Accepted Answer

Pre-created content, configuration, or data used to set up a known state for tests

Answer

Test fixtures establish a deterministic starting state (nodes, users, config) so that each test runs against consistent data and produces reproducible results.

Question 2

Which Drupal security hardening check should QA verify is enabled on a production site to prevent text injection via user input fields?

Accepted Answer

Filtering user input through an allowed HTML text format with XSS filtering enabled

Answer

Drupal's text format system with XSS filtering strips disallowed HTML tags from user input, preventing cross-site scripting attacks through content fields.

Question 3

In a Drupal project using GitLab CI, what artifact should the PHPUnit test stage produce to allow QA review of test results?

Accepted Answer

A JUnit XML report file consumed by GitLab's test reports UI

Answer

PHPUnit can output JUnit XML via `--log-junit`, which GitLab CI's `reports: junit:` artifact key parses to display test pass/fail directly in merge request pipelines.

Question 4

A QA team finds that a Drupal cron job silently fails without logging errors. What is the best practice fix?

Accepted Answer

Wrapping cron logic in try/catch blocks that log errors to Drupal's watchdog

Answer

Catching exceptions in cron implementations and logging them via \Drupal::logger() ensures failures are surfaced and actionable rather than silently swallowed.

Question 5

What does `PHPStan` with the `phpstan/phpstan-drupal` extension add to a Drupal project's quality pipeline?

Accepted Answer

Static type analysis that catches type errors and undefined method calls without running the code

Answer

phpstan-drupal extends PHPStan with Drupal-specific stubs and rules so that static analysis understands Drupal's service container, entity APIs, and hook system during type checking.
