XMLUNIT 1.3 JAR FREE DOWNLOAD

The DifferenceEngine class generates the events that are passed to a DifferenceListener implementation as two pieces of XML are compared. This separates the decision about whether two Elements should be compared from the decision about whether those two Elements are considered similar. XMLUnit provides a Validator class for this purpose. Diff and DetailedDiff 3. Let's say we have two pieces of XML that we wish to compare and assert that they are equal. Starting with XMLUnit 1. xmlunit 1.3 jar

One of the key points about using XPaths with HTML content is that extracting values in tests requires the values to be identifiable. Obviously in this case the pieces of XML are different and the test will fail. Writing XML comparison tests.

We could write a simple test class like this:. Validating XML Documents 4. Obviously we could use a DTD or a schema to validate the message output, but this approach wouldn't allow us to distinguish between valid XML with correct content e. One of the strengths of XML is the ability to programmatically extract specific parts of a document using XPath expressions. The following test uses a custom NodeTester class to illustrate the potential:.

The Validator Class 4.

And that was the beginning of XMLUnit. DOM Tree Walking 6.

XPaths are especially useful where a document is made up largely of known, unchanging content with only a small amount of changing content created by the system. This test fails as two pieces of XML are similar but not identical if their nodes occur in a different sequence. This first section contains a tour through XMLUnit's features, xmluit next sections will cover them in more detail. It allows an XML comparison to be made that ignores differences xmllunit the values of text and attribute nodes, for example when comparing a skeleton or outline piece of XML to some generated XML.

Let's say we have two pieces of XML that we wish to compare and assert that they are equal. To configure XMLUnit to use a specific parser and transformation engine set three System properties before any tests are run, e.

This interface allows an application to iterate over the Node s contained in a Documentor to "walk the DOM tree". Knowing the input XML, input stylesheet and expected output XML we can assert that the output of the transformation matches the expected output as follows:. In a purely XML world this class would have no purpose as there are plenty of Sax event handlers that can build DOM documents from well formed content. So for Element nodes, an instance of the ElementQualifier interface is used determine whether a given test Element node qualifies for comparison with a control Element node.

Note that a DetailedDiff is constructed using an existing Diff instance. This separates the decision about whether two Elements should be compared from the decision about whether those two Elements are considered similar. The test fails because the XML contains the wrong value for the last number in the sequence:. However, the contents of a NodeList can be flattened or String -ified to a single value, and XMLUnit also allows assertions to be made about this single value, as in this test [5]:.

The getResultString and getResultDocument methods of the Transform class can be used to access the result of the XSLT transformation programmatically if required, for example as below:. While the previous test could have been easily performed using XPath, there are times when Node iteration is more powerful.

The failure message indicates both what the difference is and the XPath locations of the nodes that were being compared:. The Diff class stores the result of an XML comparison and makes it available through the methods similar and identical.

Comparing XML Transformations 1. This is just another way of saying that testing HTML is easier when it is written to be testable. Testing by Tree Walking 2.

If you change the DifferenceListener or ElementQualifier after calling toString it won't have any effect. The test below illustrates its use:. Unfortunately even if your DOM implementation does support DocumentTraversalattributes are not exposed by iteration: Common Configuration Options 2.

The problem that we faced was how to verify that the system generated the correct message from a known set of inputs.
