Summary: CapsStripperTest fails on non-working days

Initial Comment:
Can anyone help to identify this error when building the testsuite project and let me know whether is a known bug and how can be fixed?

I have sucessfully installed QuantLib, and then decided to installed the XLAddIn, which compiles perfectly too but then when asked by the tutorial reference on the web to build the testsuite in order to check the QuantLib project, the compiler throw the error below which relates to cap volatilities.

I built 
I look forward to hearing from you

Thank you

Victor

This test is failing because the CapStripper (being a TermStructure) uses
an adjusted reference date whereas caps don't.

Hi Victor,

I just ran the testsuite and it passed OK.  Then I set the clock back to
25 March 2007 - the date of your bug report, and a Sunday - and I got the
exact same failure as you.  So it looks like there's a flaw in the logic of
the CapsStripper test which causes it to fail if run on 25 March 2007 - I
imagine it also fails on any other non-working day.  I'll try to arrange
for this to be fixed in the next release.

In the meantime the temporary workaround is for you to stop working on
weekends.  :-)

Regards,
Eric
