...
what it is and isn't
...
The
...
harness
...
provides
...
an
...
abstract
...
base
...
class
...
for
...
testing
...
plugins
...
and
...
an
...
increasing
...
collection
...
of
...
stub
...
implementations
...
of
...
key
...
maven
...
classes.
...
Many
...
of
...
your
...
plugins
...
contain
...
plexus
...
components
...
which
...
should
...
be
...
populated
...
by
...
the
...
container
...
so
...
in
...
your
...
test
...
cases
...
you
...
will
...
be
...
'looking
...
up'
...
a
...
mojo
...
and
...
then
...
either
...
using
...
getters
...
and
...
setters
...
on
...
it
...
to
...
setup
...
the
...
mojo
...
or
...
make
...
use
...
of
...
the
...
PlexusConfiguration
...
step
...
that
...
lets
...
an
...
xml
...
snippet
...
on
...
disk
...
configuration
...
everything
...
for
...
you.
...
This
...
plugin
...
harness
...
is
...
not
...
the
...
be
...
all
...
end
...
all
...
solution
...
to
...
mojo
...
testing.
...
It
...
does
...
not
...
do
...
integration
...
testing
...
and
...
the
...
primary
...
scope
...
of
...
the
...
harness
...
is
...
to
...
provide
...
a
...
way
...
for
...
plugin
...
authors
...
to
...
create
...
a
...
fully
...
populated
...
instance
...
of
...
their
...
mojo
...
only
...
with
...
stubs
...
in
...
the
...
place
...
of
...
critical
...
maven
...
classes.
...
This
...
is
...
an
...
attempt
...
to
...
all
...
for
...
some
...
level
...
of
...
mojo
...
testing
...
without
...
needing
...
a
...
full
...
fledged
...
maven
...
execution
...
environment.

The first step is to make a test case in src/test/java

and

extend

the

AbstractMojoTestCase

You

must

your

This

a

sample

plugin

configuration

file.
...
If
...
custom
...
expressions
...
are
...
needed
...
then
...
we
...
can
...
add
...
them
...
to
...
the
...
StubResolverExpressionEvaluator
...
class
...
in
...
the
...
plugin
...
harness
...
so
...
things
...
like
...
the
| No Format |
|---|
${basedir} |
above
...
are
...
taken
...
care
...
of.
...
Notice
...
the
...
projectArtifact
...
element
...
above
...
with
...
the
...
implementation=""
...
attribute.
...
This
...
is
...
how
...
you
...
will
...
inject
...
the
...
StubArtifact
...
implementation
...
into
...
that
...
projectArtifact
...
private
...
variable
...
on
...
the
...
mojo.
...
Additional
...
elements
...
can
...
be
...
inserted
...
as
...
child
...
elements
...
and
...
they
...
will
...
in
...
turn
...
be
...
assigned
...
to
...
the
...
variables
...
inside
...
that
...
object.
...
An
...
example
...
would
...
be
...
setting
...
the
...
groupId
...
variable
...
on
...
the
...
StubMavenProject.
...
Note:
...
these
...
internal
...
variable
...
might
...
also
...
need
...
implementation=""
...
attributes.
