public class: BeanPropertySetterRuleTestCase [javadoc | source]

java.lang.Object
   junit.framework.TestCase
      org.apache.commons.digester.BeanPropertySetterRuleTestCase

Test case for BeanPropertySetterRule. This contains tests for the main applications of the rule and two more general tests of digester functionality used by this rule.

Field Summary
protected static final  String	TEST_XML	Simple test xml document used in the tests.
protected  Digester	digester	The digester instance we will be processing.

Constructor:
public BeanPropertySetterRuleTestCase(String name) { // ----------------------------------------------------------- Constructors super(name); } Construct a new instance of this test case. Parameters: name - Name of the test case

Method from org.apache.commons.digester.BeanPropertySetterRuleTestCase Summary:
setUp,   suite,   tearDown,   testAutomaticallySetProperties,   testDigesterBodyTextStack,   testDigesterRuleCallOrder,   testSetGivenProperty,   testSetUnknownProperty

Methods from java.lang.Object:
equals,   getClass,   hashCode,   notify,   notifyAll,   toString,   wait,   wait,   wait

Method from org.apache.commons.digester.BeanPropertySetterRuleTestCase Detail:
public void setUp() { digester = new Digester(); } Set up instance variables required by this test case.
public static Test suite() { return (new TestSuite(BeanPropertySetterRuleTestCase.class)); } Return the tests included in this test suite.
public void tearDown() { digester = null; } Tear down instance variables required by this test case.
public void testAutomaticallySetProperties() throws IOException, SAXException { // need the extended rules digester.setRules(new ExtendedBaseRules()); // going to be setting properties on a SimpleTestBean digester.addObjectCreate("root", "org.apache.commons.digester.SimpleTestBean"); // match all children of root with this rule digester.addRule("root/?", new BeanPropertySetterRule()); SimpleTestBean bean = (SimpleTestBean) digester.parse(xmlTestReader()); // check properties are set correctly assertEquals( "Property alpha not set correctly", "ALPHA BODY", bean.getAlpha()); assertEquals( "Property beta not set correctly", "BETA BODY", bean.getBeta()); assertEquals( "Property gamma not set correctly", "GAMMA BODY", bean.getGamma()); } Test that you can successfully automatically set properties.
public void testDigesterBodyTextStack() throws IOException, SAXException { // use the standard rules digester.setRules(new RulesBase()); // add test rule to catch body text TestRule rootRule = new TestRule("root"); digester.addRule("root", rootRule); // add test rule to catch body text TestRule alphaRule = new TestRule("root/alpha"); digester.addRule("root/alpha", alphaRule); // add test rule to catch body text TestRule betaRule = new TestRule("root/beta"); digester.addRule("root/beta", betaRule); // add test rule to catch body text TestRule gammaRule = new TestRule("root/gamma"); digester.addRule("root/gamma", gammaRule); digester.parse(xmlTestReader()); assertEquals( "Root body text not set correct.", "ROOT BODY", rootRule.getBodyText()); assertEquals( "Alpha body text not set correct.", "ALPHA BODY", alphaRule.getBodyText()); assertEquals( "Beta body text not set correct.", "BETA BODY", betaRule.getBodyText()); assertEquals( "Gamma body text not set correct.", "GAMMA BODY", gammaRule.getBodyText()); } This is a general digester test but it fits into here pretty well. This tests that the body text stack is functioning correctly.
public void testDigesterRuleCallOrder() throws IOException, SAXException { List callOrder = new ArrayList(); // use the standard rules digester.setRules(new RulesBase()); // add first test rule TestRule firstRule = new TestRule("first"); firstRule.setOrder(callOrder); digester.addRule("root/alpha", firstRule); // add second test rule TestRule secondRule = new TestRule("second"); secondRule.setOrder(callOrder); digester.addRule("root/alpha", secondRule); // add third test rule TestRule thirdRule = new TestRule("third"); thirdRule.setOrder(callOrder); digester.addRule("root/alpha", thirdRule); digester.parse(xmlTestReader()); // we should have nine entries in our list of calls assertEquals( "Nine calls should have been made.", 9, callOrder.size()); // begin should be called in the order added assertEquals( "First rule begin not called first.", "first", ((TestRule) callOrder.get(0)).getIdentifier()); assertEquals( "Second rule begin not called second.", "second", ((TestRule) callOrder.get(1)).getIdentifier()); assertEquals( "Third rule begin not called third.", "third", ((TestRule) callOrder.get(2)).getIdentifier()); // body text should be called in the order added assertEquals( "First rule body text not called first.", "first", ((TestRule) callOrder.get(3)).getIdentifier()); assertEquals( "Second rule body text not called second.", "second", ((TestRule) callOrder.get(4)).getIdentifier()); assertEquals( "Third rule body text not called third.", "third", ((TestRule) callOrder.get(5)).getIdentifier()); // end should be called in reverse order assertEquals( "Third rule end not called first.", "third", ((TestRule) callOrder.get(6)).getIdentifier()); assertEquals( "Second rule end not called second.", "second", ((TestRule) callOrder.get(7)).getIdentifier()); assertEquals( "First rule end not called third.", "first", ((TestRule) callOrder.get(8)).getIdentifier()); } This is a general digester test but it fits into here pretty well. This tests that the rule calling order is properly enforced.
public void testSetGivenProperty() throws IOException, SAXException { // use the standard rules digester.setRules(new RulesBase()); // going to be setting properties on a SimpleTestBean digester.addObjectCreate("root", "org.apache.commons.digester.SimpleTestBean"); // we'll set property alpha with the body text of root digester.addRule("root", new BeanPropertySetterRule("alpha")); // we'll set property beta with the body text of child element alpha digester.addRule("root/alpha", new BeanPropertySetterRule("beta")); // we'll leave property gamma alone // we'll set property delta (a write-only property) also digester.addRule("root/delta", new BeanPropertySetterRule("delta")); SimpleTestBean bean = (SimpleTestBean) digester.parse(xmlTestReader()); // check properties are set correctly assertEquals( "Property alpha not set correctly", "ROOT BODY", bean.getAlpha()); assertEquals( "Property beta not set correctly", "ALPHA BODY", bean.getBeta()); assertTrue( "Property gamma not set correctly", bean.getGamma() == null); assertEquals("Property delta not set correctly", "DELTA BODY", bean.getDeltaValue()); } Test that you can successfully set a given property
public void testSetUnknownProperty() { // going to be setting properties on a SimpleTestBean digester.addObjectCreate("root", "org.apache.commons.digester.SimpleTestBean"); // attempt to set an unknown property name digester.addRule("root/alpha", new BeanPropertySetterRule("unknown")); // Attempt to parse the input try { SimpleTestBean bean = (SimpleTestBean) digester.parse(xmlTestReader()); fail("Should have thrown NoSuchMethodException"); } catch (Exception e) { if (e instanceof InvocationTargetException) { Throwable t = ((InvocationTargetException) e).getTargetException(); if (t instanceof NoSuchMethodException) { ; // Expected result } else { fail("Should have thrown NoSuchMethodException, threw " + t); } } } } Test that trying to set an unknown property throws an exception.
