When databases are involved, people will probably quickly jump to writing integration tests, because all they have to do is create a little Derby, H2 or HSQLDB or other test database, and run a couple of data-setup queries prior to the actual test. Unit testing your data access When databases are involved, people will probably quickly jump to writing integration tests, because all they have to do is create a little Derby, H2 or HSQLDB or other test database, and run a couple of data-setup queries prior to the actual test. You now have a complete unit test to exercise the DAO logic that can be run without the need for a container or database. Conclusion Hopefully this article has provided you with a useful introduction to the Mockrunner framework.

Unit testing your data access When databases are involved, people will probably quickly jump to writing integration tests, because all they have to do is create a little Derby, H2 or HSQLDB or other test database, and run a couple of data-setup queries prior to the actual test.

A common approach when using these two technologies together is to have your Actions lookup bean references from the Spring WebApplicationContext. The expected output is a resultset with “1” and “foobar”, as well as the SQL statement that is executed. Testing a data access component in isolation generally means testing it independently of a relational database. The getUser method is invoked and its results are verified. The mock SearchService is configured to expect its searchCatalog method be invoked and return a List containing one result.

Most developers involved in enterprise Java development are quite familiar with writing JDBC code to access a relational database. In this example, you can assume the user has input a valid search string, which leaves two primary test scenarios: Post as a guest Name. Unit testing is an essential practice for anyone seeking to develop better-designed, higher quality software. 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.

For the purposes of the test, the actual contents of the list are irrelevant. Mockrunner keeps track on every executed SQL statement. Let’s look at an excerpt from this class showing the key methods. By mockkrunner the API, I came across methods that are specifically meant to be used with PreparedStatements instances that I was not aware about:. This is a sample test database for MockFileDatabase Its syntax is inspired from H2’s test script files When this query is executed Once again, a call to invoke the actionPerform method is made to run the action’s execute method.

There are so many different ways of configuring and executing queries through this highly stateful APIyour unit tests quickly become unmanageable. Luckily, Mockrunner provides you with the tools to easily create tests that run out-of-container and independently of any external configuration.

Another use-case, but still worth mentioning here Some of the above libraries will not get you around the fact that JDBC is an awkward API to mock, specifically if you need to support several incompatible!

When preparing or verifying results you don’t have to provide the complete statement string. This time a verification mockruner is made to ensure an ActionMessage was bound to the request and the user was redirected to the input page. Here is the condensed working example: Let’s begin with the first scenario. Let’s begin by looking at some specific examples.

Just to name a few: To show this extension in action I’ll refactor the earlier example’s implementation class and test case. With the first test complete, it’s time to move on to testing the second scenario. As you can see above, I have already answered the question, and tried your solution, which did not yet work. Provides the central runtime behavior of the framework. Under each technology type you will find two different versions of the adapters: There are a few libraries that help you with database testing.

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 jebc results were found. Mockrunner requires no external configuration, so the first test method is complete and ready to be run. At the heart of the framework are the various test modules.
