What is it?
Knowit 4
Characterization of exploratory testing
• ”Planning and execution of testing is done at the same time”
(After James Bach)
• Test cases are not necessarily documented even afterwards (Cem Kaner)
• In exploratory testing, test design and test execution occur at the same time, guided by a prepared test
charter. (ISTQB Agile Tester syllabus)
• Testing is done iteratively piece by piece
• Continuous learning and interpretation
• Utilization of knowledge gained from experience

Exploratory testing - terms
• Test Charter
• Divide your testing areas and assign missions
to each
• Testing area: a bunch of functionalities
• Exploration
• Adventure may go to sidetrack as long as you
come back to mainroad again (Kaner)
• Testing session
• Duration about ½ - 2 hours
• Why?
• Time span of concentrated work is about
20 minutes
• Getting back to work takes about 20
minutes

After reference: Psychology of Usability, Sinkkonen et al.
Learning from the system and customers
• What has changed or changes frequently?
• What do the customers want?
• What has been defined in an ambiguous way?
• Where do faults cluster?
• Weaknesses in the platform or programming language
• System dependencies
8© Copyright Knowit Oy 2015 | Confidential
Reference: Lessons learned in software testing. Kaner, Bach, Pettichord
Learn from other testers, designers, from yourself
• What kind of errors do certain programmers make and how to report to and communicate with them
• What typical errors can there be in the system
• What functionalities have been built in a hurry
• What have you misunderstood and what is typically misunderstood
• How can the system be tested (especially in pair testing!)

Why exploratory testing?
Knowledge-based perspective
• Exploit the natural diversity of people in testing *)
• ”Do not plan for store”
• Systematic variation of testing
• Quick feedback to designers / developers intensifies learning process *)
• Spread the knowledge of a tester of a special area
10© Copyright Knowit Oy 2015 | Confidential
*) Reference: Exploratory testing: A multiple case study. Itkonen,
Rautiainen
Why exploratory testing?
Testers’ approach
• Want to add more test cases and increase the coverage of the tests *)
• For defining the degree of automation of tests
• Quick overview of the quality *)
• Testing the side effects of changes – scripted testing can end up testing only the documented features *)
• The problem in regression testing is the selection of test cases, which requires user experience and
understanding of the system
• When the test documentation can not be written in advance *)
11© Copyright Knowit Oy 2015 | Confidential
*) Reference: Exploratory testing: A multiple case study. Itkonen,
Rautiainen
Why exploratory testing?
Management approach
• Low management costs of test documentation
• Finding out the features of a poorly-documented component
• Optimizing the productivity of testing?
• When the available workload is limited *)
• When you want to train the customer support at the same time

Purpose of test charter(s)
• What will be tested?
• What documents are available?
• What kind of errors are being sought?
• Tasks and what test techniques will be used?
• What will be expected from test sessions?
• A dashboard?
• Defect reports?
• Some key test cases?

Ref. Exploratory testing: A multiple case study. Itkonen, Rautiainen
Test design within test charter
• Define the testing areas of the test object
• E.g. 20-40 areas covering whole system under test
• Divide each area to one or more test sessions
• Test charter works as a roadmap for each test session
• Define test cases to be documented as a by-product, if any
• heuristic: less than 10% of all tests
• Write down test ideas and/or high level test cases

Test Charter example ISTQB
23© Copyright Knowit Oy 2017 | Confidential
• Actor: intended user of the system
• Purpose: the theme of the charter including what particular objective the
actor wants to achieve, i.e., the test conditions
• Setup: what needs to be in place in order to start the test execution
• Priority: relative importance of this charter, based on the priority of the
associated user story or the risk level
• Reference: specifications (e.g., user story), risks, or other information
sources
• Data: whatever data is needed to carry out the charter
• Activities: a list of ideas of what the actor may want to do with the system
and what would be interesting to test (both positive and negative tests)
• Oracle notes: how to evaluate the product to determine correct results
• Variations: alternative actions and evaluations to complement the ideas
described under activities

Exploratory Testing - Heuristics
• A set of heuristics can be applied when testing.
• A heuristic can guide the tester in how to perform the testing and to evaluate the results, few examples
below
28© Copyright Knowit Oy 2015 | Confidential
Heuristics Examples
Boundaries: Approaching the Boundary e.g. almost too big, almost too
small, at the Boundary
CRUD Create, Read, Update, Delete
Configuration variations Varying the variables related to configuration e.g. Screen
Resolution; Network Speed, Latency, Signal Strength; etc.
Interruptions e.g., log off, shut down, or reboot
Source: Elisabeth Hendrickson www.testobsessed.com/wp-content/uploads/2011/04/testheuristicscheatsheetv1.pdf
Performance attitude - professional working
• Keep the mission, your targets of testing in mind
• Write down observations and questions about the system
• Report in a disciplined and systematical way
• During the execution, write only the most essential test cases and in high level
• Test cases can be refined later, if needed
29© Copyright Knowit Oy 2015 | Confidential
Tests are designed during execution
• Design test on the basis of charter its initial test
ideas
• Define tests from any questions in your mind
• A surprising situation may indicate an error:
Utilize the surprise effect!
• Use heuristics e.g.
• ”Backwards thinking”: ”This button saves
the definition text. I wonder what other ways
are there for saving the text?”
30© Copyright Knowit Oy 2015 | Confidential
Note taking: test execution logs
• Keep a test execution log / notes
• Keep track of the tests carried out
• Main thing is that executed tests are noted down, not the detail
• You may create scripted test cases from some of the tests, add detail
• Note what test data you used in your tests
• You may record your execution with a suitable tool, only need to add your comments
• Add status to your notes e.g. with color-coding
• Write down also notes for test session post-mortem and your own learning
31© Copyright Knowit Oy 2015 | Confidential
Note taking: defect logs
• After session work out defect reports for defects you found, based on your notes
• In defect reporting, traceability to the requirements must be maintained so that coverage can be
evaluated
• A well written execution log is the best evidence of the existence of a fault
• Report a bug clearly, so that the failure can be repeated
• You may use defect reporting systems

Measuring exploratory testing
• The duration of the session
• The relative change in the number of test cases by the same tester
• Coverage of testing per session
• The number of interruptions (Suspension criteria)
• Number of rejected defects in defect database
• …
• Metrics are the eyeglasses of testing that you need in order to be fully aware of the situation and
potential problems in testing
•  It is recommended that you choose metrics that are suitable for the challenges of exploratory
testing

• ”Pioneer-style”
• Everyone can learn to be an exploratory tester
38© Copyright Knowit Oy 2015 | Confidential
Reference: Choosing and Managing the Ideal Test Team. Lloyd Roden
Exploratory testing requires learning skills
• Outline the functionality of the system on paper
• Aim at understanding
• Don’t force yourself to remember facts, use documents
• Ask questions about the functionality of the system
• Recognize the items on which you need more information
39© Copyright Knowit Oy 2015 | Confidential
Reference: Tutkiva oppiminen. Hakkarainen et al.
Improve your testing thinking skills
• Observe your own testing habits
• Recognize your own ways of thinking
• Learn from misunderstandings and mistakes
• Select the testing techniques according to the situation *)
• Improve your skills to deduce the states of the system *)

What in future?
Knowit 44
Exploratory future
• Exploratory testing will become the norm in agile testing
• And agile will be the norm for all development
• Testing tools suites will include exploratory testing charters and logging
• Coverage will be proven with both last quantities of well-logged exploratory testing and some formally
designed test cases
• With test automation to make sure the basics work, testers will be free to find important defects with
exploratory testing
• People will start exploring also with test automation
• Keyword driven and data-driven approaches
• AI will help with some of Exploratory Testing
