I think this could be really useful feature in for many users!

What would be the most important data for you that you would like to obtain from the API?

Primarily we are interested in the “failed test cases” table content as shown in robot reports page, the “all test suites” may also be useful but that is secondary.

JENKINS-22546: Added initial api functions to robot result

I've tested this plugin with version 1.5.0 and while the robot general information about the specific build is available (total number of tests, tests passed/failed, pecentage of tests passed), the information about the individual failed test cases is missing.

Sample output using xml rest api:

<robotResult>
<allFailedCase/>
<allFailedCase/>
<allFailedCase/>
<criticalFailed>3</criticalFailed>
<criticalPassed>27</criticalPassed>
<criticalTotal>30</criticalTotal>
<overallFailed>3</overallFailed>
<overallPassed>27</overallPassed>
<overallTotal>30</overallTotal>
<passPercentage>90.0</passPercentage>
<suite/>
<timeStamp>20140523 15:24:06.067</timeStamp>
</robotResult>

I tried adding "?depth=2" or "?depth=3" to see if more information would be displayed on sub-levels but it returned the same output.

I also have the same problem, when I query result, the json looks like this: 

allFailedCases': [\{}, \{}, \{}, \{}, \{}, \{}]

Would it be possible to get this fixed? 

I'm guessing this plugin is dead, but I figured I would chime in to let anybody working on it know that the allFailedCases feature would be super helpful.

We would like that as well.
