Authentication and diagnostic functions for a database system

A user authentication method comprising:

• maintaining, at a user system, a persistent database storing a plurality of different access tokens that facilitate single sign-on to a plurality of different tenants of a multi-tenant database system;
• executing a native client application at the user system, the native client application providing stand-alone and non-browser based support of an information networking environment that involves the plurality of different tenants of the multi-tenant database system;
• receiving, with the native client application at the user system, login data for a first tenant of the plurality of tenants;
• processing the received login data with an authentication engine of the user system;
• logging the user into the first tenant when the processing results in authentication of the user;
• and
• automatically logging the user into at least one additional tenant of the plurality of tenants, using at least one of the access tokens stored in the persistent database.

A method of testing computer executable code, the method comprising:

• defining a plurality of test cases, each corresponding to a different browser-based function carried out by computer executable code;
• performing code coverage tests on each of the plurality of test cases by emulating the different browser-based functions;
• obtaining test results for the plurality of test cases, in response to performing the code coverage tests;
• and
• providing a consolidated report that includes the test results for the plurality of test cases.
