You begin by annotating your test class with
@RunWith
. This tells
JU
nit to use the named
test runner instead of the standard
JU
nit one. The Pax Exam
JUnit4TestRunner
class
is responsible for starting the relevant framework, deploying bundles, and running the
tests. The
@Configuration
annotation identifies the method that provides the Pax
Exam configuration. Right now, you ask it to deploy the standard
OSG
i compendium
bundle
B
from Maven central in to the default framework. The actual test method is
annotated with the usual
JU
nit 4 annotation,
@Test
. It accepts a
BundleContext
argu-
ment that's supplied by Pax Exam at execution time. You use this bundle context to print
out various properties, including the symbolic name of the test bundle
C
.
To run this test, type the following:
$
cd chapter07/testing-example
$
ant test.container
You should see something like the following, but with properties that match your system.
