The method you're testing for this class is obviously read() . This method requires two external
dependencies: an instance of an ItemReader (remember, you used a JdbcCursorItemReader in the actual
job) and a reference to your TickerDao . To test this method, you have two test methods, one for each of
the method's two execution branches (one for when the customer is null and one for when it isn't).
To start this test, let's create the test-case class and the @Before method so your objects are built for
later use. Listing 12-5 shows the test case with the setup method identified with the @Before annotation
and three class attributes.
