How can I improve the test coverage of MetadataService.cls (recent Version for API v35)?

Question

I'm using the APEX wrapper for Metadata API found here https://github.com/financialforcedev/apex-mdapi

Looking at the test coverage, there are a lot of lines uncovered. Can this be improved easily?

Answer 1

I posted an issue report on github here https://github.com/financialforcedev/apex-mdapi/issues/119

I've created the missing invocations to get the coverage close to 100%

Add this code (also in the github-issue) into your MetadataServiceTest.cls and you will be fine:
