Incorrect Name of Value in XML Configuration File
Description
A SpringUnit test fails because the name
of a value referenced within a test
in the Java source code cannot be found
in the XML configuration file.
Symptoms
junit.framework.AssertionFailedError
at junit.framework.Assert.fail(Assert.java:47)
...
Cause
This error occurs when the name of a value referenced in a
test method in the Java source code
cannot be found in the XML configuration file.
The getObject method in
org.springunit.framework.SpringUnitTest and
org.springunit.frameowrk.SpringTransactionalTest
returns null if it can find no match in the test context.
This can lead to unexpected null values, or in
NullPointerExceptions.
Remedy
If the name of the value in the XML configuration is misspelled,
then correct it.
If it is missing altogether, then add an entry for it in the
map associated with the test in the XML configuration file.
Example
Java Source Code:
package org.springunit.examples.errors;
import org.springunit.framework.SpringUnitContext;
import org.springunit.framework.SpringUnitTest;
public class IncorrectNameOfValueInXmlTest extends SpringUnitTest {
public void testOne() throws Exception {
String str = getObject("str");
String expected = getObject("expected");
assertTrue(expected.equals(str));
}
public SpringUnitContext getIncorrectNameOfValueInXmlTest() {
return incorrectNameOfValueInXmlTest;
}
public void setIncorrectNameOfValueInXmlTest(
SpringUnitContext incorrectNameOfValueInXmlTest) {
this.incorrectNameOfValueInXmlTest = incorrectNameOfValueInXmlTest;
}
private SpringUnitContext incorrectNameOfValueInXmlTest;
}
