Need Help with rerun-fails

[lovefromindia]

thanks for gotestsum package

We use below command on our Build but rerun didn't worked as expected.

gotestsum --rerun-fails --packages="./..." --format testname --junitfile ../../jsonreport.xml -- -coverprofile=../../cover.out ./... -p 7 -timeout 0

Is it because of using -p flag for parallel testcases? Any test case which failed only ran once and not twice as expected!

Hello! Thank you for the bug report.

The only thing I notice from the command you shared is that ./... appears twice. Once in as the value for --packages , and again after cover.out. It is correct to pass that value to --packages, but I think you need to remove the second one after cover.out. I'm not sure if that is causing the problem or if it's something else.

The -p flag should be ok, I haven't seen problems with that before.

Can you share some of the test output? How many tests are failing, and are any failing with a panic?

Thanks for the response.
We already removed the twice occuring packages and then also the rerun didn't worked
For panic part, I ensure no panic occured and assertions failed for the test case but I expected rerun for the test cases that failed. That didn't occured
Also, for argument -packages do we need to list all packages instead of recursive package path "./..." ? With -count=2 all test cases ran twice as expected but not with only rerun-fails

I just wanted to know if I am doing anything wrong with command that my script generates to run at build environment?

gotestsum --rerun-fails --packages="./..." --format testname --junitfile ../../jsonreport.xml -- -coverprofile=../../cover.out -p 7 -timeout 0

Can you try with adding the --debug flag to gotestsum ? That will print out the go test commands that are run each time. That should help us understand why there is no rerun.

If you can share some output of the test run that may help us debug, but from what you've shared I don't see anything that would prevent the re-runs.

Thanks for the quick response, dnephin
I thinks issue was with the argument of packages="./...". Instead we list out all packages in double quotes e.g. "a b c" and now reruns works as expected.
Now the coverage report generated is of last run. Is there any argument that gotestum give so that i can get combined coverage report of all runs?

[dnephin]

Ah, yes there is a way to make that work. See #274 (comment), and this demo repo: https://github.com/neiser/gotestsum-rerun-dependent-subtests
