Confusion between BehatContext and MinkContext

I am trying to make BDD in my Symfony 2.3 project and it seems to be struggling with some inconsistencies.

Depending on whether I use BehatContext or MinkContext as the base class for the FeatureContext class, I get different results.

If I use:

class FeatureContext extends BehatContext

everything is fine. however, if I use:

 class FeatureContext extends MinkContext

I get errors that make it look like MinkContext no longer likes my regular expression, which the system itself generates. Could you help me understand:

Extend RawMinkContext if you need to access a Mink session (to automate the browser).

Do not use Goutte directly.

BehatContext is the base context that will be used by default for most of your own contexts when you don't need Mink.

MinkContext is a specialized context that gives you access to a Mink session (just like RawMinkContext ). However, it also contains some basic step definitions. That's why you should never expand it, but rather use it as a subcontext. You could only extend it once, since step definitions cannot be duplicated.

The question is very similar to your other question (see an example of using Mink there): What is wrong with my FeatureContext?

Using Behat does not mean that you are following BDD . To learn more about this, read the following books:
