- Added extension/Dynatrace.js to wrap exec / execute / prepare functions with dynatrace tracing
- Modified the Client to automatically wrap with dynatrace tracing when isDynatraceEnabled()
is true (@dynatrace/oneagent-sdk is installed and HDB_NODEJS_SKIP_DYNATRACE is off) and
the dynatrace connect option is true
- Added the dynatrace and dynatraceTenant connect options
- Modified ResultSet.js to have the getRowCount function
- Added 2 unit tests for getRowCount
- Added the isDynatraceSupported field to the driver (Hana class)
- Added the MockDynatraceSDK for testing and added integration tests for dynatrace
Testing Notes
The Makefile was modified so that `make test-dynatrace` will test only the dynatrace integration tests
To install the MockDynatraceSDK, copy the contents of the MockDynatraceSDK folder into
node_modules/@dynatrace/oneagent-sdk
The integration tests were designed to be able to dynamically run on the mock dynatrace and the real
dynatrace depending on the node_modules import
- Updated the create table hook to allow the tests to be run without a config.json
- Modified Dynatrace.js result set callback to allow array results to indicate the rows returned not just result sets like before - Added an integration test to check that an insert with execute would trace the number of rows affected

This could use a more descriptive string. Right now it's identical to a previous test.

There should be an args.length > 0 check here, similar to _ExecuteWrapperFn. This also applies to hana-client and Ian McH will fix it there

This comment isn't relevant here, should just remove it
- Added an index check to ensure that the callback when preparing statements for dynatrace exists and is a function - Improved some test naming to better indicate client execute tests vs. client exec and statement execute tests - Added a comment to indicate when numbers are returned for rows affected
