Failure in running unit tests Jenkins job

[Daniel Donciu]

We encountered this error during our unit tests Jenkins job execution. It happens sporadically, at least once a week, but sometimes we get 3 or 4 good runs in a row and then several failures like this. When this happens the job dies after a random number of unit tests – sometimes it can execute as few as 5 unit tests, or it can go run half of the unit tests, but then the rest of unit tests are not executed as the job stops with error. The datasource quoted in the error is random, it can quote any of the datasources. Please advise.

Hi Daniel,

Apologies for the late response. I have talked to our framework specialists and they have mentioned that the stacktrace above simply tells us that NexJ server isn’t able to connect to the database and doesn’t provide any other detail. A suggestion at this point is to look at the server logs and see if any other details show up above or after this stack trace.

Perhaps database resources are running out when this unit test job fails and they are freed up and available for NexJ server when this job runs successfully.
