Dbunit run sql file

For tests that use a database it is crucial to be able to set up the database to a known state before each test run. Otherwise such tests tend to be very fragile and will require a lot of manual care to keep them green over time as they will often fail due to different database contents.

Suppose we want to test a class called PersonRepository that loads instances of Person from the database. For example, the method findPersonByFirstName should load the first person with a specified first name. How can we test this method? Our first test might look like this:. A crucial part is missing though: the setup. How to improve the performance of my DbUnit tests? How to automatically order tables by their foreign keys? How to exclude some table columns at runtime? How to filter rows of an ITable by checking their column values?

Is there an equivalent to JUnit's assertEquals double expected, double actual, double delta to define a tolerance level when comparing numeric values? Can I add more information to the result of an assertEquals double expected, double actual call so that I can easily identify the rows that mismatch? How to use InsertIdentityOperation with user defined types? How to customize primary keys detection? I'm getting the following message: Extra columns on line x. Those columns will be ignored.

Please add the extra columns to line 1, or use a DTD to make sure the value of those columns are populated. Why is that? Is there any way I can specify the current system time for my testcase? Are Postgresql enum types supported by dbunit? Why am I getting an "The configured data type factory 'class org. DefaultDataTypeFactory' might cause problems with the current database Why am I getting a "Foreign keys constraint violation" error?

Why am I getting a "data type not recognized" warning? Why am I getting the following error: "java. General Which relational database systems are supported? Building DbUnit detailed instruction.

Dbunit provides support for verifying whether two tables or datasets contain identical data. The following two methods can be used to verify if your database contains the expected data during test cases execution.

The following sample, show how to compare a database table snapshot against a flat XML table. The actual dataset is a database snapshot you want to verify against an expected dataset.

As its name imply, the expected dataset contains the expectation values. The expected dataset must be different from the one you have used to setup your database. Therefore you need two datasets to do that; one to setup your database before a test and another to provide the expected data during the test. You can also verify if the result of a query match an expected set of data. The query can be used to select only a subset of a table or even join multiple tables together.

Sometimes this is desirable to ignore some columns to perform the comparison; particularly for primary keys, date or time columns having values generated by the code under test. One way to do this is to omit to declare unwanted columns in your expected table. You can then filter the actual database table to only expose the expected table columns. The following code snippet shows you how to filter the actual table.

Extra columns can exist in the actual table but not in the expected one. With a DTD you need to filter columns from both the expected and the actual table. See the FAQ about excluding some table columns at runtime. By default, database table snapshot taken by DbUnit are sorted by primary keys.
