Myrna van Lunteren updated DERBY-5912:
--------------------------------------
Attachment: DERBY-5912_2.diff
Attaching a patch that:
- changes the timeout in ConnectionMethodsTest from isValid(1) to isValid(200)
and adds a comment
- updates the comment in ConnectionTest so it refers to ConnectionMethodsTest
- has commented out sleep code in DRDAConnThread that can be uncommented to
test this
- adds a fixture, testIsValidWithTimeout, that is disabled by having an 'x' in
front of it, to ConnectionTest.

> The test does:
> // Test with a 1 second timeout
> assertTrue(getConnection().isValid(1));
> assuming it will return in one second. For embedded the int parameter is not
> implemented so indeed this always passes. For the Network implementation in
> NetConnection40.java we actually do timeout and perform a query as part of
> the implementation so might indeed return false.
