Do you have experience working with databases and how have you used them in your projects?

Yes, I have experience working with databases in testing and automation. I usually used databases for:

• Preparing test data before running tests.
• Verifying data correctness after operations.
• Checking data integrity and consistency.

For example, when automating web application tests, I connected to databases (e.g., MySQL or PostgreSQL) to insert necessary records, then ran tests, and checked that data changed as expected. I used database libraries in the automation language (e.g., psycopg2 for Python).
