Framework Components — quiz

A team hardcodes `baseUrl = "https://dev.example.com"` in their test classes. Running the same tests against staging requires a global find-and-replace. Which configuration approach best solves this?

• Add a second test class for staging tests that overrides the URL
• Externalise the URL to a `config.properties` file, read at runtime, and override per environment via environment variable (`BASE_URL`). Tests read from a `Config` singleton — changing environments means changing a variable, not touching test code
• Add an `@Ignore` annotation to all dev-targeting tests before running against staging
• Use a feature flag system to toggle between environments at runtime
