# `described_class` makes tests harder to read. When using tools that allow
# jumping between definitions and the respective tests in a Rails project, or
# using global search, the class `described_class` refers to might not be clear
# to the reader. By avoiding the shortcut, we make sure the test stands on its
# own with as much information as possible.

# Examples should focus on testing one thing, but that does not necessarily
# translate into a single expectation. For instance, testing validations in
# a Rails model should assert (1) the model is invalid, (2) the model has
# validation errors, and (3) these errors not only include the target field
# but also the target error message. Another example would be testing
# side-effects are contained.
#
# Similarly, not limiting the number of expectations in an example invites
# colaborators (and consequently reviewers) to forget the rule of testing one
# thing only, or to simply ignore it due over the "simplicity" and comfort of
# checking for everything in a single test.
#
# Therefore, this cop should remain enabled, but its value should be adjusted 
# as reasonable for the project.
