DBUnit is a very effective tool for testing persistence layer code. This is where a dataset comes into picture. XML datasets can be easily created by exporting data from an existing database.
Here are three simple steps for doing this:. Here is a portion of dataset generated:. An interesting thing to keep in mind is that when DBUnit is used to load this dataset into a database, it would read the first element to figure out the table metadata. This behavior can be avoided by generating a DTD that contains table column information.
This is done using the following code: FlatDtdDataSet. Once the DTD is in place, it can be included in the dataset doctype declaration. I am using SQL Server database and i want to read the below xml. But i am getting Table not found error even after adding the qulaifiedtablenames property. Notify me of follow-up comments by email. Notify me of new posts by email. Here are three simple steps for doing this: Create a connection to the database.
Using the DiffCollectingFailureHandler you can avoid an exception to be thrown on a data mismatch so that you can evaluate all results of the data comparison afterwards. Nearly all tests need to load data from one or more files, particularly for prep or expected data.
The available loaders are in package org. A simple usage example:. Note the constructors for the various DataFileLoaders accept replacement object and replacement substring maps as used with ReplacementDataSet. WebTest is a tool to simulate a user's browser clicking through the pages on a web site.
It allows you to create a series of Ant based tests for your website. This document walks you through a suggested format for storing tests. Your first step is to create your dataset file that you want to load into your database before running your WebTest script. Use one of the various methods described above. A suggested setup is to have a single build. This would include a couple targets like:.
Once you have your build. This way you can either run all the test's in your Test Suite, or just run a specific one, all from build. Now you need to write your various testcases. For more information on WebTest, please refer to the WebTest home page. If you have a single set of properties, then load them as part of build. If you have multiple databases you need to connect to, then declare your sql connection properties in a TestSuiteXXX. Version: 2. JUnit DBUnit.
Quick Links Maven 1. You may modify this behavior by overriding getDatabaseTester , using one of the other 3 provided IDatabaseTester implementations or your own. Database data verification Dbunit provides support for verifying whether two tables or datasets contain identical data. Sample The following sample, show how to compare a database table snapshot against a flat XML table.
Using a query to take the database snapshot You can also verify if the result of a query match an expected set of data. Ignoring some columns in comparison 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. Row ordering By default, database table snapshot taken by DbUnit are sorted by primary keys. Or you can use the SortedTable decorator class like this: Assertion.
Assert and collect the differences By default, dbunit immediately fails when the first data difference was found. Data File Loader Nearly all tests need to load data from one or more files, particularly for prep or expected data. Step 1: Create your dataset file Your first step is to create your dataset file that you want to load into your database before running your WebTest script. Step 2: Create your Ant build. This would include a couple targets like: test : Runs all the testSuites that you have created test:single : Runs a single test in a specific testSuite test:suite : Runs all the tests for a specific testSuite.
Step 3: Create your various Test Suites Once you have your build. Step 4: Create your various Tests Now you need to write your various testcases. All Rights Reserved. This is the default implementation used by DBTestCase.
