- Tester’s utilization: Tester can contribute right from beginning of development. They get opportunities to utilize personal skills, experience and knowledge. It adds value to their work and motivates them to make valuable contributions toward product quality goals. Testers who are skilled at ET can bring great value to team(s). ET brings freedom and fun to testers daily work and increases the sense of accomplishment.
- Simultaneous learning: Automated tests can definitely help to execute checks/tests quickly but humans have the unique capacity to connect the dots and come up with different test scenarios. Testers can gain sufficient knowledge from available feature or user documentation and learn further about system behaviour while testing — and try to understand how system may fail at test or production. This way tester can learn, design, execute, improve the test scenario and test at run time understanding the input data and test results. Tester spends more time on testing and thinking or brainstorming about different perspectives along with sufficient defect logs. If you are running Automated Tests then ET can also provide input to it, if those specific exploratory tests can be automated to save testers’ time.
- Less test preparation: ET requires less documentation, I would say tester only need to know the purpose of testing and then he/she can start experimenting with it. It is easy to create ET test charter (an outline of goal or mission for exploratory session). It identifies fields that add values to testing and saves time from extra documentation.
- Rapid feedback: Comparing with the tradition test case based approach, ET approach bridges testers and programmers — and establishes a fast feedback communication channel. Testers can focus and spend time on key areas and provides feedback on quality to do quick and necessary reforms in development. This is beneficial for management to get to know product quality status earlier and faster — and address those areas which require priority and focus. If there are quality risks in architecture or system design then it must be fixed sooner without wasting time and money. This is ideal in Agile environment as well.
- Effectiveness in finding critical bugs: There are (though few) empirical studies to determine the effectiveness of ET. But in everyday testing, testers know that besides Automated Tests, testers are exploring and thinking differently to find bugs customer can face. Under controlled environment, it showed that ET is effective in finding bugs of different severities and reveal difficult defects to detect.
