- 5. 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) • Testing is done iteratively piece by piece • Continuous learning and interpretation of conceptions • Utilization of knowledge gained from experience © Copyright Knowit Oy 2015 | Confidential 5
- 6. EXPLORATORY TESTING -TERMS • Adventure may go to sidetrack as long as you come back to mainroad again (Kaner) • Testing area: a bunch of functionalities • Testing session • Duration about ½ - 2 hours • Time span of concentrated work is about 20 minutes • Getting back to work takes about 20 minutes © Copyright Knowit Oy 2015 | Confidential 6
- 7. AN EXAMPLE: WWW.TOPSELLERS.COM,A FICTIONAL E-COMMERCE SHOP • Test case: ”Log in. Browse the content of your shopping cart. Result: Shopping cart is empty, because no items have been picked.” • During testing it is noticed that the shopping cart contains items! Items have been picked with the same user account and the e-commerce shop keeps the earlier picked things in shopping cart. • Aftertaste: ”The test should have considered this. Let’s change the test data and the test itself, and design a new test case, which takes into account that the shopping cart can store items.” • A familiar situation? © Copyright Knowit Oy 2015 | Confidential 7

LEARNING FROM THESYSTEM 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 Reference: Lessons learned in software testing. Kaner, Bach, Pettichord © Copyright Knowit Oy 2015 | Confidential 9
- 10. LEARN FROM OTHERTESTERS, 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!) © Copyright Knowit Oy 2015 | Confidential 10
- 11. WHY EXPLORATORY TESTING? KNOWLEDGE-BASEDPERSPECTIVE • Exploit the natural diversity of people in testing *) • ”Do not plan for store” • Systematic variation of testing • Quick feedback to the designers intensifies learning process *) • Spread the knowledge of a tester of a special area *) Reference: Exploratory testing: A multiple case study. Itkonen, Rautiainen © Copyright Knowit Oy 2015 | Confidential 11
- 12. 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 *) *) Reference: Exploratory testing: A multiple case study. Itkonen, Rautiainen © Copyright Knowit Oy 2015 | Confidential 12
- 13. WHY EXPLORATORY TESTING? MANAGEMENTAPPROACH • 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 *) Reference: Exploratory testing: A multiple case study.

- 26. PERFORMANCE ATTITUDE - PROFESSIONALWORKING • Keep the targets of testing in mind • You can visit bypaths but only for a moment • 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 © Copyright Knowit Oy 2015 | Confidential 26
- 27. TESTS DURING EXECUTION •Define a test from a question • Design test on the basis of charter and test ideas • A surprising situation may indicate an error: Utilize the surprise effect! • ”Backwards thinking”: ”This button saves the definition text. I wonder what other ways are there for saving the text?” © Copyright Knowit Oy 2015 | Confidential 27
- 28. NOTE TAKING: TESTEXECUTION LOGS • Keep a test execution log • Keep track of the tests carried out • Main thing is that executed tests are noted • You may create scripted test cases of some of the tests • Keep the most important test cases that have been executed, which show how the testing has been done, e.g. what values have been used • You may record your execution • Write down also test notes for test session post-mortem and your own learning © Copyright Knowit Oy 2015 | Confidential 28
- 29. NOTE TAKING: DEFECTLOGS • In defect reporting, traceability to the requirements must be maintained so that coverage can be evaluated • A well written error 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 © Copyright Knowit Oy 2015 | Confidential 29

WHO TO RECRUIT?THE PROFILE OF AN EXPLORATORY TESTER • Exploratory testing is particularly well suitable for a person, who… • likes to take risks • is not afraid of changes or new things • is open-minded • sets challenges and goals to themselves • is smart and quick in finding test conditions • ”Pioneer-style” • Everyone can learn to be an exploratory tester Reference: Choosing and Managing the Ideal Test Team. Lloyd Roden © Copyright Knowit Oy 2015 | Confidential 34
- 35. EXPLORATORY TESTING REQUIRES LEARNINGSKILLS • 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 Reference: Tutkiva oppiminen. Hakkarainen et al. © Copyright Knowit Oy 2015 | Confidential 35
- 36. CONSIDER THE LEARNINGSTYLES • When you explore the system functionality, *) • are you trying the system yourself? • do you ask a colleague to explain? • do you create models of the software functionality? • are you interested in the details or are you trying to understand the overall picture? • Some learn by trying, others socially, others by thinking… *) Reference: Learning Styles and Exploratory Testing.

- 37. RELIABLE INFORMATION TOSUPPORT TESTING • Sources of information: background documents, own experience, interviews... • Conceptions are created about the system and the specifications • Are the documents reliable? • What is the "fact"? • Evaluate the sufficiency of the information sources Formation of conception repor- ting design findings © Copyright Knowit Oy 2015 | Confidential 37
- 38. BE CRITICAL • Informationhas inconsistencies and errors • Exploratory testing is not a substitute for professional documentation • Find out what data sources the customer considers to be stone carved definitions of and facts about the software • Find out what to do if the specifications contradict each other • Be suspicious! Suspect everything! © Copyright Knowit Oy 2015 | Confidential 38
- 39. IMPROVE YOUR TESTINGTHINKING 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 *) Adapted from the reference: Tutkiva oppiminen.
