</xsl:template>

Asserts that two Strings are equal.

Parameters:

expected - The expected result of the test
actual - The actual result of the test
tolerateWhitespace - If this is "1", then differences in whitespace are ignored in the comparison
message - An (optional) message to be used in case of test failure

Asserts that a String is not null.

Parameters:

actual - The actual value to be tested
message - An (optional) message to be used in case of test failure

<xsl:template name="alster:assertNull">
  <xsl:param name="actual"/>
  <xsl:param name="message"/>
</xsl:template>

Asserts that a String is null.

Parameters:

actual - The actual value to be tested
message - An (optional) message to be used in case of test failure

<xsl:template name="alster:assertEqualsAsNode">
  <xsl:param name="actual"/>
  <xsl:param name="expected"/>
  <xsl:param name="message"/>
</xsl:template>

Asserts that two DOM node objects (or result tree fragments) are equal. Node equality is tested via the template with name="alster:assertNodeEquality" .

Parameters:

expected - The expected result of the test
actual - The actual result of the test
message - An (optional) message to be used in case of test failure

<xsl:template name="alster:assertNotEqualsAsNode">
  <xsl:param name="actual"/>
  <xsl:param name="expected"/>
  <xsl:param name="message"/>
</xsl:template>

Asserts that two DOM node objects (or result tree fragments) are unequal. Node equality is tested via the template with name="alster:assertNodeEquality" .

Parameters:

expected - The expected result of the test
actual - The actual result of the test
message - An (optional) message to be used in case of test failure

<xsl:template name="alster:assertNodeEquality">
  <xsl:param name="actual"/>
  <xsl:param name="expected"/>
  <xsl:param name="level" select="$LEVEL_NODE_NAME"/>
</xsl:template>

This "private" template asserts that two DOM node objects (or result tree fragments) are equal. In case of inequality, a message describing the type of inequality is generated.
The template is called recursively, testing different levels of node comparison in each step. If no iteration detects a difference, then the nodes are considered equal.
In detail, the nodes are equal if and only if the following hold:

• The nodes have equal names,
• the nodes have the same number of attributes,
• the nodes have the same attributes (i.e. the same set of key/value pairs),
• the nodes have the same number of subelements,
• the nodes have the same subelements,
• the nodes have the same number of text nodes,
• the nodes have the same text node values.

Parameters:

expected - The expected result of the test
actual - The actual result of the test
level - The current node comparison level
