Functional and Load Testing Tools for WCF Data (OData) Services

This post consolidates my experience of various testing tools that so that you can pick best for you purpose.
Little Background
Here is the types of testing that you can perform against OData based service

Testing Types
Testing Objective
Functional Testing Making Sure that you are getting result for all supported query types
Schema Validation Making sure that you service respect to OData protocol standards
Unit Testing Making sure during development time that major end point/queries are working and nothing has been broken.
Regression Testing Making sure the your services are up and running and there has been response content is intact over the time.
Data Validation Making sure that service are giving result exactly as expected according to database
Load Testing Making sure that you server is ready to handle expected load factors with acceptable response time.
Payload Testing Making sure that payload size of service is acceptable to organizational constraints defined. This may require lazy loading or Entity Page size manipulation

All above may require sufficient amount of time if right tool is not chosen very first. Below is the list of testing tools available for different need.
