Subject RE: ec2 API compatibility (WSDL vs Query)
Date Thu, 02 Aug 2012 19:35:41 GMT
Hi,

EC2 SOAP API testing has been done. 
Here are test results : http://wiki.cloudstack.org/display/QA/EC2+API+support+-+Test+Execution

Two test cycles are done. Second cycle is done to cover failed and blocked test cases from
first run
	Total test cases run 250+
	Total Passed 200 +

Defects can be found in JIRA

Thanks
/Sudha

Subject: RE: ec2 API compatibility (WSDL vs Query)

The only metric that we have (to my knowledge) is that the Query API was broken for a long
time (a problem with the signature-checking code, so nothing worked at all).  So the SOAP
API is the one that's had all the love from us.  If you have test results, then that's far
better.
