是否可以并行重新运行失败的黄瓜测试？

Question

Is there a way to pass a text file with failed cucumber features to parallel_cucumber?

Example: You have a cucumber.yml with a parallel profile

#cucumber.yml
parallel: -r features --format ParallelTests::Cucumber::FailuresLogger --out rerun.txt

you can run

bundle exec parallel_cucumber -o "-p parallel"

You can run the output rerun.txt file with the command

bundle exec cucumber @rerun.txt

How can I rerun the failures in parallel?

Answer 1

I figured out how to do this after a bunch of googling/trial and error. Settled on this for the rerun command.

bundle exec parallel_cucumber -n 40 -o "-p parallel" --group-by scenarios `cat rerun.txt`

They key part is --group-by scenarios `cat rerun.txt`

The other stuff in there is just the syntax for specifying a cucumber profile with parallel tests and the number of threads to run it on.

The full makefile for the CI job looks like this:

FEATURE?=features/

run_tests:
    @echo ---- running tests ----
    @bundle exec parallel_cucumber -n 40 -o "-p parallel" ${FEATURE} --ignore-tags @flaky,@broken --group-by scenarios || \
    @if [ -s rerun.txt ]; then \
        echo "-------> tests failed, rerunning" ; \
        RERUN='RERUN ' bundle exec parallel_cucumber -n 40 -o "-p parallel" --group-by scenarios `cat rerun.txt`; \
    fi

.PHONY: run_tests

Thanks @dSkech for reminding me to answer my own question.
