No, you cannot do this. This is not the intended use of Examples.
Examples are a nice way to show how some function will behave: Examples exists to document. The main reason for validating the example output is to make sure the Examples are valid/correct, not that your code is okay. For the later you have Test functions
Most often the output of an Example displays input and output (or just output) of one invocation of a certain function/method per line; sometimes Examples use the different lines to show parts of a complex result, e.g. one line per element of the returned slice.
I think your use of Examples to "verify the flow of my program" contradicts the intention of Examples. I would use Test functions and use any of the available diff tools to generate a got, want, diff output myself if I'd like to test e.g. a text processor on large bunches of input.
