You have three environments: dev, staging, and prod. You want Cypress to load different baseUrl and env variables automatically based on a NODE_ENV variable. Which approach is best?
AHardcode all URLs and env variables in tests and skip config
BCreate three separate config files and manually rename before each run
CUse a single <code>cypress.config.js</code> that reads <code>process.env.NODE_ENV</code> and sets config dynamically
DUse environment variables only in test files, not in config
Step-by-Step Solution
Solution:
Step 1: Understand dynamic config loading
Reading process.env.NODE_ENV inside cypress.config.js allows dynamic config based on environment.
Step 2: Compare alternatives
Manually renaming files is error-prone; hardcoding in tests is bad practice; env only in tests misses config benefits.
Final Answer:
Use a single cypress.config.js that reads process.env.NODE_ENV and sets config dynamically -> Option C
Quick Check:
Dynamic config based on NODE_ENV is best practice [OK]
Quick Trick:Use process.env.NODE_ENV in config for environment-specific settings [OK]
Common Mistakes:
Manually renaming config files before runs
Hardcoding URLs inside test code
Ignoring config benefits by setting env only in tests
