Adjusting the Model: Better Statistics

Let’s learn how the statistics of the tests could be improved using the optional weight call back.

We'll cover the following

Adding the call back

Let’s take a look at the call-backs

The call back is in the test/break_test.exs file in the code below between line 78 and line 90. It has been highlighted.

The call raises the probability of any call forcing a transition from ok to tripped and also increases the probability of all error calls in the ok state. The rest of calls, such as error calls that are already in the tripped state and manual blocks, remain neutral in terms of probabilities.

Let’s run the code and see what we get.
