📖 What is Data-Driven Testing?

Data-Driven Testing is a scripting technique that stores test inputs and expected results in an external data source, such as a spreadsheet or database. A single test script iterates through this data to execute the same scenario with multiple values.

🥋 Sensei Says:

"This is a classic exam topic. If a question asks how to test a login page with 50 different user/password combinations efficiently, Data-Driven Testing is your answer."

📚 Certification: Certified Tester Foundation Level (CTFL-v4.0)

🔑 What are the Key Concepts of Data-Driven Testing?

  • Separation of test data from the test script logic.
  • Allows one script to execute multiple test iterations using different data sets.
  • Improves test coverage and reduces script maintenance.

🎯 How does Data-Driven Testing appear on the CTFL-v4.0 Exam?

A question about how to efficiently test an application that requires validating hundreds of different input combinations.

Identifying the technique where test values are read from a CSV file during execution.

❓ Frequently Asked Questions

What are the main benefits of data-driven testing?

It significantly reduces the amount of code needed, makes it easy to add new test cases just by updating a spreadsheet, and separates test logic from data.


Do you need programming skills for data-driven testing?

Setting up the initial framework and script requires programming skills, but adding new test data often does not.

Equivalence Partitioning vs Boundary Value Analysis: ISTQB

Equivalence Partitioning (EP) divides input data into groups that should be processed identically, reducing test cases by testing one representative value per group. Boundary Value Analysis (BVA) complements this by testing the edges of these partitions, where defects frequently occur, ensuring the system handles limits and transitions correctly.
