gradle discrepancies

[zeners]

i found the following needed actions, please correct me, if i'm wrong

• [X] SerenityTask need removing clearHistory and history as mentioned by @petrandreev
• [X] build.gradle should use tasks.register
• [X] .all should be replaces with configureEach in build.gradle
• [X] test-Task need useJUnitPlatform() to run the tests
• [X] what's happen to #30 ?
• [X] JUnit5-test-classes should be package-private
• [X] contains-assertions should be written asassertThat(...).contains(...); (currently assertThat(....contains(...));
• [X] create README-file with detailed usage descriptions

i tested the actions with a simple test-project and with active --build-cache --configuration-cache getting the following result:

• clean test without change: create empty result

  > Task :test FROM-CACHE
  > Task :aggregate

• test after change: create index with no results pages listed (after clean test)

  > Task :test
  > Task :aggregate UP-TO-DATE

  this looks like test create output, that aggregate uses without the knowledge of gradle-cache

gradle writes output into build, serenity into target/site/serenity, clean only remove serenity inside target/site

hi @zeners, regarding your Q about generateOutcomes, not needed before- it's been changed here:https://github.com/serenity-bdd/serenity-gradle-plugin/commit/3424830cb766d87cc669524396988cb8dc9dd444 It used to be always set, now one needs to set it to "true" on PluginExtension explicitely. Thanks for summing up

[zeners]

i can't test the deployment, so i hope that i didn't broke something

[wakaleo]

Just published the new version, feel free to test

[zeners]

@wakaleo thank you

the cache doesn't work as expected. I'm afraid that we have to use the complete outputDirectory from test.

• gradle clean test -x aggregate --build-cache --configuration-cache should create the test-result without report:

  ...
  > Task :test 
  

• gradle clean test --build-cache --configuration-cache should build the reports, based on cached test output

  > Task :test FROM-CACHE
  > Task :aggregate
  Generating Serenity Reports

  but the generated report is empty, because the test-results are missing will try to write a test addressing this

[tnielens]

Hi here, Sorry to jump in. Was #19 reverted? From what I tested only #30 to fix the missing test results needed to be merged for it to work properly. Internally we're using a published version including #30 and we observe no issues with the plugin.

[zeners]

c7e03104d352446d0b4b8a80094075b3c762b6c7 was an undo of #19, but 3424830cb766d87cc669524396988cb8dc9dd444 makes a redo, but with differences

currently i'm afraid that's not possible to make a consistent result, if you test without aggegate (test -x aggregate) and after it clean test will run aggregate without test-results, not restored from cache.

i have a plan in mind, but need some time to implement and test

[tnielens]

Thanks for clarifying.

As for aggregate, we don't understand well its behavior as it doesn't play well with the project-scoped expectation of gradle. That task seems to collect outputs from all subprojects in a multimodule project although the task exists in each project. Also the static/global state of serenity prevents use of gradle parallelism and running parallel tasks in a multi-module project leads to concurrency issues in serenity tasks and outputs.

Aside of these issues, #19 was a welcome improvement 👍.

[zeners]

That task seems to collect outputs from all subprojects in a multimodule project although the task exists in each project.

assuming the gradle-plugin should work like the maven-plugin, as outlined in https://github.com/serenity-bdd/serenity-maven-plugin/issues/22#issuecomment-176633201 you have to set a common output-directory in all subprojects, to get one report for all subproject tests, correct?

[petrandreev]

Solved reports generation issue in a muli-module project with v 4.1.10 (happens on RH UBI, e.g. linux, not on Mac though...) on my side. IMHO the issue has nothing to do with gradle cache(s) -

1. test task (JSONTestOutcomeReporter actually) generates reports into serenity.conf's outputDirectory (build/site/serenity)
2. on aggregate task, Gradle decides that the whole directory, configured by serenity plugin extension's outputDirectory is stale and deletes it!:

   > Task :serenity:aggregate
   Deleting stale output file: ......../build/site/serenity

3. aggregator has nothing to work with since no JSON outcomes - no reports in the site HTML!

The both configured outputDirectory s must point to the same location- otherwise JSON reports are not picked up for further processing, not sure why....

Solution: declare either

• input of aggregate task to be build/site/serenity directory or
• output of the test task to be build/site/serenity directory

Gradle then takes into account that there could be some other output, besides aggregate's one, and doesn't delete the entire build/site/serenity directory- aggregate picks JSONs up and produces HTML report.

P.S. thanks to @tnielens - yes i forgot to mention that this setup is not recommended by gradle - but I currently I don't see any other way to generate reports- it doesn't work otherwise...

[tnielens]

Gradle incremental build and task cache (to be distinguished from the configuration cache) don't work reliably if multiple tasks output results in the same directory. You'll see warnings in the log about this.

[zeners]

• test-results are not only the json-files, but also can (at least) include downloadable and (screenshot)pictures
• these outputs should be known to gradle and connected via input/output between the task
• the connection of output and input creates a direct dependency between these 2 tasks (test and aggregate)
• i like to see test and aggregate be separate to call (now you have to exclude aggregate, when running test, but that's ok)

we can copy the test-result-files to a aggregate-working directory to split the test-output from the aggregate output - but this would be a breaking change

[wakaleo]

I'm reverting all of these changes as they have caused a number of regressions.

[zeners]

wich ones?

[wakaleo]

https://github.com/serenity-bdd/serenity-core/issues/3468

[zeners]

we should found a way to go with configuration cache

[tnielens]

@wakaleo are we back with #19 merged and the small fix #30 as well? That's what we run in my org, and it works fine, configuration cache included. Some issues with overlapping output directories for the task cache, but nothing blocking so far.

[wakaleo]

@wakaleo are we back with #19 merged and the small fix #30 as well?

I'm rolling back all the changes. There are too many issues being raised and I don't have time or the Gradle knowledge to deal with them.

[tnielens]

As said above, if you include #30, #19 works fine. I can provide support to iron out issues and increase the test coverage.

[wakaleo]

30 was included in the code base. I will roll it all back and you are welcome to redo the PRs, but we need an up to date sample project as the Gradle unit tests don't pick up all the issues.

[zeners]

would be nice to run tests before merged

[wakaleo]

would be nice to run tests before merged

To run the full test suite you need to publish the plugin - if you can find a way to run end-to-end tests with the Gradle plugin without needing to publish it that could work better.

[zeners]

that's that the tests currently do, no need to be published previuosly

[wakaleo]

There are unit tests, but since Groovy is a dynamic language they don't pick up all the issues, which only appear when you run the plugin against a real project. If you know how to write local end-to-end tests that do pick up these issues that would be a great help.

[zeners]

could github run these tests on PR as an action?

[wakaleo]

No, because if you run them against a project separately, you need to publish the plugin first which can only be done by hand. (We do run the Gradle unit tests for each build, but they are not sufficient).

[tnielens]

@wakaleo gradle has great support for e2e tests (they call it functional tests). Doesn't this suite fulfill your requirements?

[zeners]

currently tests are insufficient: accepted the only check currently run is the GitGuardian Security Checks i like to see the tests running as check on PR

[wakaleo]

No it does not. We get lots of errors appearing when we actually try the tests out on a real project that don't appear in these tests.

Can you propose a PR on the Github actions to do this?

[tnielens]

The current test coverage in the project is gappy. We can add a lot more test cases. The multi module test suite was added to cover a particular failure scenario.

i'm not familiar with github actions, will take a look, will need time, maybe someone is faster ;)

More tests would be very welcome.

[tnielens]

19 added several tests which were reverted unfortunately. I suppose they can be reapplied without the main code patch easily.

[tnielens]

For github actions, here is some doc by gradle: https://docs.gradle.org/current/userguide/github-actions.html#sec:configure_github_actions . I'll try that out.

[tnielens]

There was a workflow already in place, but it didn't run on PR: https://github.com/serenity-bdd/serenity-gradle-plugin/pull/35 .

[zeners]

it works, the tests failed:

[tnielens]

@zeners see the comments in the PR. The current master revision is broken it seems. The plugin cannot register certain tasks.

[zeners]

that have been fixed and is now rolled back?

[tnielens]

@wakaleo patched master. The tests now pass.

[zeners]

so we have now a working master and checked test on PR: thanks!

[tnielens]

@zeners what are your plans here. Do you intend to resubmit your changes? I'd like to resubmit the configuration cache support originally submitted in #19 but would like to avoid working on the same tasks as you.

[zeners]

@tnielens i would like to resubmit, after having tests for the issues, but it will take some time (may be at weekend) please feel free to start

[tnielens]

for my understanding, did any of your changes concern the configuration cache?

[wakaleo]

for my understanding, did any of your changes concern the configuration cache?

No

[zeners]

@tnielens any news/progress?

[tnielens]

No. I haven't started yet. I intended to start from the former configuration cache PR #19 plus my small fix #30. Feel free to take a head start if you wanna work on this this weekend.

[tnielens]

@zeners @wakaleo I just checked latest revision 5ee4d91 on master. I don't face any configuration cache issues. Not sure what you reverted @wakaleo but as far as I checked, the configuration cache is functional with the serenity plugin applied.
