[ http://issues.apache.org/jira/browse/HARMONY-31?page=all ]
George Harley updated HARMONY-31:
---------------------------------
Attachment: PerfDecorator.java
The attached file contains source for a type test.foo.utils.PerfDecorator that
can be used to make straightforward timing measurements
on JUnit test cases as they run. As the code is really only for illustrative
purposes I send the information to stdout.
Here is an example of how this class could be used to decorate a test suite
(apologies in advance for any formatting
problems that may occur)...
public static Test suite() {
TestSuite suite = new TestSuite("My test suites");
suite.addTestSuite(MyTestSuite.class);
// Wrap the test suite "suite" inside the PerfDecorator...
PerfDecorator pd = new PerfDecorator(suite);
return pd;
}
> Move peformance timing of unit tests into a decorator class.

> There has been some low-level discussion on the dev mailing list recently
> about the inclusion of performance-related logging code near the top of a
> unit test class inheritance hierarchy (see
> com.openintel.drl.security.test.PerformanceTest in the HARMONY-16
> contribution). This particular issue suggests an alternative way of adding in
> timing code but without making it the responsibility of the unit tests
> themselves and without the need to introduce a class in the inheritance
> hierarchy.
> The basic approach is to exploit the junit.extensions.TestDecorator type in
> the JUnit API to add in timing behaviour before and after each test method
> runs. This will be demonstrated with some simple sample code.
