Session-based testing

Session-based testing is a software test method that aims to combine accountability and exploratory testing to provide rapid defect discovery, creative on-the-fly test design, management control and metrics reporting. The method can also be used in conjunction with scenario testing. Session-based testing was developed in 2000 by Jonathan and James Bach.

Session-based testing can be used to introduce measurement and control to an immature test process and can form a foundation for significant improvements in productivity and error detection. Session-based testing can offer benefits when formal requirements are not present, incomplete, or changing rapidly.

Elements of session-based testing

Mission

The mission in Session Based Test Management identifies the purpose of the session, helping to focus the session while still allowing for exploration of the system under test. According to Jon Bach, one of the co-founders of the methodology, the mission tells us “what we are testing or what problems we are looking for.” [1]

Charter

A charter is a goal or agenda for a test session. Charters are created by the test team prior to the start of testing, but they may be added or changed at any time. Often charters are created from a specification, test plan, or by examining results from previous sessions.

Session

An uninterrupted period of time spent testing, ideally lasting one to two hours. Each session is focused on a charter, but testers can also explore new opportunities or issues during this time. The tester creates and executes tests based on ideas, heuristics or whatever frameworks to guide them and records their progress. This might be through the use of written notes, video capture tools or by whatever method as deemed appropriate by the tester.

Session report

The session report records the test session. Usually this includes:

Debrief

A debrief is a short discussion between the manager and tester (or testers) about the session report. Jonathan Bach uses the aconymn PROOF to help structure his debriefing. PROOF stands for:-

Parsing results

With a standardized Session Report, software tools can be used to parse and store the results as aggregate data for reporting and metrics. This allows reporting on the number of sessions per area or a breakdown of time spent on testing, bug investigation, and setup / other activities.

Planning

Testers using session-based testing can adjust their testing daily to fit the needs of the project. Charters can be added or dropped over time as tests are executed and/or requirements change.
