Option to allow failures in Fan-In/Out Workflow

The requires tag in workflows really limits what is possible. Requires makes a lot of sense for the deployment scenario used to demo it, but waiting for a group of jobs to complete (pass or fail) should be an option.

Scenario: Setup -> Run multiple sets of tests in parallel -> Combine test results/coverage results/artifacts and report to PR

That scenario above isn’t possible because if a single test fails in any of the jobs running in parallel the the fan-in step won’t run.

    Use case for me is a smoke test job that runs against master before deploy (should fail and prevent further jobs running , namely build and deploy) but also runs on a nightly schedule in which case it should be able to fail and still have the following job run to notify devs of the failure

    • steps requiring failure to cease flow

    - hold-staging:

    type: approval


    - smoke-test

    • job requiring failure to continue flow



    - schedule:

    cron: "5 8 * * *"




    - master


    - smoke-test

    - smoke-test-notification:


    - smoke-test

    This will be huge for us!

    There's been a fair amount of comments on this and no word from CircleCI.


    Having worked with thousands of CCI pipelines this has been a huge pain point for us.

    We would like to add tests, that are still under development. getting a notification on their failure is important but they should not be blocking the pipeline yet

    +1.  Very important for testing purposes

    I'd also like to see this feature implemented.

    Here is my use case:

    I've setup parallelisation for end to end tests, so I've got 4 jobs that run and produce test report files.

    Then after all the tests are done, and regardless of their success or failure, I need to combine all those test report files and compile them into a centralised test report website (I am using allure test report).

    This is because for E2E tests it is very important to have a comprehensive report, with logs and screenshots. The junit thing is not sufficient for this kind of project.

    especially important in automation

    There hasn't been an update on this idea for a couple of months... can someone from CircleCi weigh in to offer a workaround or let us know whether it will be considered for implementation?

    The ability to define a job within a workflow to run regardless of the failures in a previous job is a useful feature. It would be great to work similarly to how the "when: on_fail" key works when a step fails within a job. The reason for this in the pipeline design, it makes sense for many of us to run cleanup or postprocessing jobs at the end of the runs.

    Important for cleaning up resources if the previous jobs fail.

    Important for us as well.

    We have resource provisioning jobs that run in parallel to the build stages since resource provisioning takes long-ish. We do some light checks (`go vet`) before provisioning, but these are not a 100% guarantee that build won't fail. We would need this feature to ensure that resources get cleaned up in every case.

    Also interesting in that. As a final step of workflow we want to report to some external systems.

    We would also really like this feature as well. We have different test suites running in different jobs and would like to be able to aggregate results in a final job regardless of the pass/fail status of the "required" jobs.

    This is important for us for the same reason Ed mentioned - "clean up jobs that have to run even if a step in the workflow fails".

    Hope voting on this makes a difference and this feature will be supported!

    This is important for a lot of projects that test against HEAD of an upstream project, e.g. github.com/clojure-emacs/cider. We want to know as soon as possible if things are breaking against unreleased versions of Emacs, but at the same time, we don't want to block merging, or report a total failure. Sometimes those broken things may not be our fault, and are later fixed upstream.

    This is super important for clean up jobs that have to run even if a step in the workflow fails.

    Copying over from: https://discuss.circleci.com/t/continue-running-other-jobs-after-required-job-fails/24334


    Building upon [the discussion here](https://discuss.circleci.com/t/could-selected-jobs-be-configured-to-generate-a-warning-instead-of-pass-fail/22395/4), I'd like a way for a **job** to run even though a previous **job** in the workflow has failed in some way.

    I know about [`when`](https://circleci.com/docs/2.0/configuration-reference/#the-when-attribute) for a **step**, but there doesn't seem to be something like this for a workflow's **job**.

    We're currently having to do something like `test_lib || true` to make the CI step pass even though it's actually a failure. That's definitely a code smell to us.

    Example use case:

    # this is a `job` in CircleCI's vernacular
    - report_build_statuses:
    - install_gem_dependencies
    - lint_with_danger
    - build_app
    - test_lib
    filters: *ignore_certain_pr_builds

    ## Expected Behavior

    In this scenario, I'd like the `report_build_statuses` job to run even though the `test_lib` job failed some tests (and it depends on that job running, either successfully or not, before it can run).

    So this would:
    1) Report back to Github that `test_lib` failed its tests
    2) Run `report_build_statuses` which would summarize those failings in a GitHub comment (we do this using [Danger](http://danger.systems/ruby)) and avoids us having to dig through CircleCI logs to figure out what failed

    ## Existing Behavior

    Currently, it just fails the `test_lib` job and then never runs `report_build_statuses` because apparently the `requires` keyword has the requirement that each job _succeeds_ rather than just requiring that each job runs.
