Exploratory Testing

Exploratory Testing is a dynamic testing approach where tests are simultaneously:

  • Designed
  • Executed
  • Evaluated

This process happens as the tester learns about the system being tested. It allows testers to deeply explore the application, identify untested areas, and create targeted test cases on the fly.

Key Characteristics of Exploratory Testing

  1. Simultaneous Process:
  • Test design, execution, and learning happen together.

2. Focus on Learning:

  • Helps understand the test object and uncover areas needing deeper testing.

3. Flexibility:

  • Useful when specifications are limited or under time constraints.

Session-Based Exploratory Testing

To add structure, exploratory testing often uses session-based testing, which includes:

  • Time-Boxed Sessions:
  • Testing happens within a predefined duration.
  • Test Charter:
  • Defines objectives for the session and serves as a high-level guide.
  • Debriefing:
  • A discussion with stakeholders after the session to share results and insights.
  • Documentation:
  • Test session sheets record steps, findings, and observations.

When to Use Exploratory Testing

  • Limited Specifications:
  • When requirements or documentation are incomplete.
  • Time Pressure:
  • When quick and focused testing is needed.
  • As a Complement:
  • To enhance coverage alongside formal testing techniques.

Skills for Effective Exploratory Testing

  • Experience and Domain Knowledge:
  • A strong understanding of the application and its context.
  • Analytical Skills:
  • The ability to think critically and identify potential problem areas.
  • Curiosity:
  • A natural drive to explore and question the applicationโ€™s behaviour.
  • Creativeness:
  • Innovative thinking to devise meaningful and unexpected test scenarios.

Advantages of Exploratory Testing

  • Adaptable to changing requirements.
  • Identifies unanticipated defects.
  • Encourages testers to engage deeply with the application.
