Under each technology type you will find two different versions of the adapters: I contacted the authors of mockrunner and the issue was resolved by the developers several month later: Its focus is on transparently simulating your application’s runtime environment so you can easily create unit tests that run out-of-container and independently of deployment descriptors or other external artifacts. This method creates an instance of MockResultSet which will be returned when the executeQuery method is called on the PreparedStatement. Testing Struts The Struts framework is often the key technology used in an application’s web tier.

Close Are you sure you want to delete this document? For the purposes of the test, the actual contents of the list are irrelevant. For instance, if you are testing a servlet class that directly looks up and interacts with an EJB, the non-basic version may be useful to you. The test modules provide the runtime testing behavior and are used to mimic the functionality of the J2EE container. In the next test we simulate a valid transaction.


Once again, jdvc call to invoke the actionPerform method is made to run the action’s execute method. Finally, a quick check is made to ensure the values contained in the ResultSet have been properly mapped into the User object. This mckrunner provides a quick overview over the JDBC test framework.

There are methods specific to PreparedStatement objects: Mocks help you to achieve this goal by providing a replacement object, which implements the same interface, but contains little or no state or behavior.


These categories do not necessarily denote a particular object hierarchy, but rather represent a conceptual grouping. Unfortunately, testing Struts Actions can be difficult due to their dependence on objects managed mockrunnerr the web container and the Struts infrastructure itself. There are a few libraries that help you with database testing. This is a sample test database for MockFileDatabase Its syntax is inspired jdnc H2’s test script files When this query is executed Despite the simplicity of the example, it still illustrates several concerns common to most JDBC code.

Since there is only a single SQL query to be executed, the global binding is sufficient.

In this post, however, we will mockrrunner on the first kind of test: The advantage of this is that your tests can be written in a way to verify your business requirements, your user stories, or whatever you call them. Mockrunner allows you to bind this ResultSet either locally, meaning to a specific SQL query, or globally so it will be the ResultSet returned regardless of the query executed.

A workaround is to use statementHandler. The connection is established, but I only get an empty result set. Assuming your application has an adequate level of abstraction, you will likely find the basic versions more generally applicable and will be the ones on which I will focus in this article.

It then invokes the business logic tier’s searchCatalog method and depending on the results returned from the service, the action will either populate the request with the list of results or an ActionMessage indicating no results were found.

There is also an experimental implementation of a Mockrunnea text-based mock database that uses the following format:. Check out the release for an example. At the heart of the framework are the various test modules.

The diagram in Figure 1 shows a high-level view of how the classes in the various categories relate. In this example, you can assume the user has input a valid search string, which leaves two primary test scenarios: With the test fixture configured you can move on to test the getUser method.

There are more examples in the release, especially one that demonstrates how to combine the JDBC test module with the other test modules of Mockrunner.

The importance of doing the right test-driven development is to find a good ratio of what kind of code is to be covered….
