What are the different types of exploratory testing techniques?

Since, few days i have been researching about diffrent types of exploratory techniques but cound’t find any, would anyone please guide me on this particular topic.

Exploratory Testing as the name suggests is based on the tester exploring the website or app to be able to make it better with time. It is a substantial activity in an Agile software development, where the development and the testing cycles go hand in hand.

Following are the different types of exploratory testing techniques:

1. Scenario-based Exploratory Testing

Scenario-based Exploratory testing is when the user Explores and tests a particular scenario or functionality. Based on the learning and observation of the website or app, and its functionalities, the tester could explore and find defects for different scenarios using an Exploratory Testing technique. They tend to check a different set of possibilities with scenario-based exploratory testing.

2. Strategy Based Exploratory Testing

The approach of this type of exploratory testing is based on strategies such as boundary value analysis, risk evaluation, equivalence technique. To perform strategy based exploratory testing, the tester must be familiar with the website or application functionalities to be able to conduct it with efficiency for better results.

3. Freestyle Exploratory Testing

Freestyle Exploratory Testing is used mainly when the tester wants to do a quick smoke testing. As the name suggests, it does not have any defined approach, scenario or coverage of testing, instead, the tester proceeds in freestyle to investigate about defects. To be able to conduct a freestyle exploratory testing efficiently, the tester must be familiar with the website or app to be able to get hold of defects easily without any detailed planning.
