In database table testing, what is the significance of testing for indexing?
- Indexing helps in improving data security
- Indexing helps in improving query performance
- Indexing helps in reducing data redundancy

Testing for indexing in database table ensures that appropriate columns are indexed to improve query performance. Indexes allow the database engine to quickly locate rows based on the indexed columns, thus speeding up data retrieval operations. However, improper indexing or lack of indexing can lead to slow query performance, especially in large databases. Therefore, testing for indexing is crucial to ensure optimal database performance.
