Video Summary – Pekka Klärck: Data-Driven Testing with Robot Framework

Introduction

Pekka (creator of Robot Framework) introduces the topic: building data-driven test cases in Robot Framework.

Initial Example

Starts with a basic login test case using the keyword-driven approach.

Works fine for a single workflow but becomes inefficient if you need multiple similar tests (invalid username, invalid password, empty fields, etc.).

Challenge with Duplicates

Creating separate test cases for each scenario leads to duplication and makes it hard to see differences.

Solution: Data-Driven Approach

New File for Invalid Login Tests (invalid.robot)

Imports existing resource file with keywords.

Defines multiple test cases (invalid username, invalid password, both invalid, empty fields).

Custom Keyword (Invalid Login)

Takes username and password as arguments.

Opens login page, inputs credentials, and validates login fails.

Uses setup/teardown to manage browser opening and closing.

Validation

Introduces Error Page Should Be Open keyword (similar to existing Welcome Page Should Be Open) for consistency and reusability.

Compact Syntax

Demonstrates how arguments can be provided directly in test case rows.

Uses built-in ${EMPTY} variable for empty credentials.

Problem of Repetition

Each test case still repeats the Invalid Login keyword.

Solution: use Test Templates.

Test Templates

Apply Invalid Login as a test template, so every test case automatically uses it with different arguments.

Adds headers (username, password) for clarity.

This produces a clean, compact, and readable test structure.

Limitations Noted

Execution is still slow (browser opens/closes for each test).

Will be optimized in a future video using suite-level setups.

Conclusion

Robot Framework, while keyword-driven, can also handle data-driven testing elegantly.

Using test templates creates a fluent, compact syntax.

Next video will focus on suite setups for faster execution.
