objects are actually used. In this case a successor is only used for
its
latestStart and a predecessor is only used for itsearliestFinish. So as a result we create two interfaces which onlyhave the methods we actually use.

MF Bliki: RoleInterface
-
With a role interface, however, we look at how the collaborating
objects are actually used. In this case a successor is only used for
its
have the methods we actually use. -
The strength of a role interface is that it clearly communicates
the actual collaboration between an activity and its successors -
A header interface forces you to
implement every method, even if you're not going to need them; but
with a role interface you only need to implement exactly what's needed. -
On the whole I much prefer role interfaces, so I suggest pushing
towards them as much as you can. -
belief has always been that you should only use interfaces
when you really need substitutability, and if you do need
interfaces you should think hard about what the consumer of that
interface needs.

Mocks Aren't Stubs

-
you begin developing a story by writing your first
test for the outside of your system, making some interface object your
SUT. By thinking through the expectations upon
the collaborators, you explore the interaction between the SUT and its neighbors - effectively designing the outbound
interface of the SUT -
the expectations on the mocks provide a specification for
the next step and a starting point for the tests -
You first start by programming the UI using
mock layers underneath -
You get the domain objects to
do what you need and once they are working you layer the UI on top.
Doing this you might never need to fake anything -
attention on the domain model first, which
helps keep domain logic from leaking into the UI -
work
feature by feature rather than layer by layer -
Mockist tests, however, only need to create the
SUT and mocks for its immediate neighbors. This can avoid
some of the involved work in building up complex fixtures -
you have
to create mocks with every test -
failure in a
highly used object causes a ripple of failing tests all across the
system.Mockist testers consider this to be a major issue
-
Usually the culprit is
relatively easy to spot by looking at which tests fail and the
developers can tell that other failures are derived from the root
fault. Furthermore if you are testing regularly (as you should) then
you know the breakage was caused by what you last edited, so it's not
difficult to find the fault. -
Since classic tests exercise multiple real objects,
you often find a single test as the primary test for
a cluster of objects, rather than just one -
finer grained
tests are needed for collaborators -
if you find yourself with a debugging
problem due to overly coarse-grained tests, you should debug in a test
driven way, creating finer grained tests as you go -
classic xunit tests are not just unit tests, but
also mini-integration tests -
whichever style
of test you use, you must combine it with coarser grained acceptance
tests that operate across the system as a whole -
implementation changes are much more likely to
break tests than with classic testing -
more flexible in
its specification of the expectations to allow expectations to be
looser in areas where it doesn't matter -
Mockist testing supports an outside-in approach while developers who
prefer a domain model out style tend to prefer classic testing -
mockist testers
tend to ease away from methods that return values, in favor of methods
that act upon a collecting object -
encourages you to tell
an object to do something rather than rip data out of an object to do
it in client code -
issue with state-based
verification is that it can lead to creating query methods only to support
verification -
Mockists favor role interfaces and assert that using
this style of testing encourages more role interfaces -
I don't see any compelling benefits
for mockist TDD, and am concerned about the consequences of coupling
tests to implementation -
I really like the fact that while writing the test
you focus on the result of the behavior, not how it's done -
One is if you're
spending a lot of time debugging when tests fail because they aren't
breaking cleanly and telling you where the problem is -
mockist testing may encourage the development team to
create more behavior rich objects

I was addicted to eliciting emotions and I couldn’t imagine anything farther from my audience than the Internet.
-
software can have personality and feel more alive than anything else I’ve ever created. Because thousands of users are using something I’ve created in realtime, it responds almost immediately to the slightest modifications. Moving a button, changing a color, rewriting copy. All of it matters and in different and surprising ways. This is so different from creating framed art work for a gallery where feedback and the possibility of response and interaction is difficult and mostly non-existent.

a:hover { color: yellow } /* user hovers */
a:active { color: lime } /* active links */Note that the A:hover must be placed after the A:link and A:visited
rules, since otherwise the cascading rules will hide the 'color' property of the A:hover
rule. Similarly, because A:active is placed after A:hover, the active
color (lime) will apply when the user both activates and hovers over
the A element. -
