public class TagTester
extends java.lang.Object

Tag tester is used to test that a generated markup tag contains the correct attributes, values etc. This can be done instead of comparing generated markup with some expected markup. The advantage of this is that a lot of tests don't fail when the generated markup changes just a little bit.

It also gives a more programmatic way of testing the generated output, by not having to worry about precisely how the markup looks instead of which attributes exists on the given tags, and what values they have.

Example:

  ...
  TagTester tagTester = application.getTagByWicketId("form");
  assertTrue(tag.hasAttribute("action"));
  ...

public static TagTester createTagByAttribute(java.lang.String markup,
                                             java.lang.String attribute,

Static factory method for creating a TagTester based on a tag found by an attribute with a specific value. Please note that it will return the first tag which matches the criteria.

Parameters:

markup - the markup to look for the tag to create the TagTester from

attribute - the attribute which should be on the tag in the markup

value - the value which the attribute must have

Returns:

the TagTester which matches the tag in the markup, that has the given value on the given attribute
