Method Detail

getProperties

public Properties getProperties()

Description copied from class: TestCase2

Reads in the configuration properties for the test from a variety of resources and returns a properties hierarchy. If a property name is not bound at the top-level of the returned Properties object, then the lower levels of the hierarchy are recursively searched.

The hierarchy is constructed from the following properties files in the following order. The first property file in this list corresponds to the top of the property hierarchy. The last property file in this list corresponds to the bottom of the property hierarchy. The property resources are:

1. The System properties specified using the -D argument on the command line.
2. ${user.home}/build.properties. ${user.home} is the value of the Java system environment variable named "user.home" and corresponds to the user home directory. A warning is logged if this properties file does not exist. Note: The JUnit UI can wind up with a different value for this property than when you execute tests without the UI. It is an error if the properties file exists but can not be read.
3. {class}.properties, where {class} is the class name reported by Java reflection, is loaded iff it is found.
4. {class} is repeatedly truncated by dropping the last package name component to generate a package name. If a properties file named "test.properties" exists in that package then those properties are loaded.

Overrides:

getProperties in class TestCase2

Returns:

A Properties object that supplies bindings for property names according to the described hierarchy among property resources. The returned Properties is NOT cached. TODO This does not handle the recursive truncation of the class name to search for "test.properties" yet.

test_correctCollator

public void test_correctCollator()

test_keyBuilder_unicode_trailingNuls

public void test_keyBuilder_unicode_trailingNuls()

Test examines the behavior when the SuccessorUtil.successor(String) of an Unicode string is formed by appending a nul character and reports an error if the resulting byte[] when the key are formed compares as equal to the original string from which the successor was formed.

Note: Since Collator.IDENTICAL appears to be required to differentiate a trailing nul character (i.e., the successor of some Unicode string), then I would strongly recommend that you form the sort key first and then its successor (by appending a trailing nul).

doSuccessorTest

protected boolean doSuccessorTest(String s,
                      Properties properties)

Test whether or not the Collator will differentiate Unicode strings that differ only in a trailing nul character.

Parameters:

s - The Unicode string.

collator - The collator.

Returns:

True iff the collector differentiates between the string and its successor (formed by appending a nul character) in its generated sort keys.
