The take a look at design and test execution activities are performed in parallel commonly without formally documenting the test situations, test cases or check scripts. This does no longer mean that different, extra formal trying out techniques will now not be used.
For example: the tester might also decide to apply boundary cost analysis but will assume via and take a look at the most vital boundary values with out always writing them down. Some notes may be written at some point of the exploratory-testing session, in order that a record may be produced afterwards.
