Danger plugin to validate the code coverage of the files changed in a pull request

danger-xcov's Issues

Scheme name not shown on danger error message

Hi, thanks for this plugin - I am trying to integrate it within our ci pipeline and so far the integration it's been pretty smooth.

We have a workspace composed of many subprojects/schemes, and I run the xcov plugin multiple times within our Dangerfile. This gives me different coverage reports per different schemes which is pretty handy. The only issue I am facing is that, if I get errors on minimum coverage not met in more than one scheme, the message does not show the name of that particular scheme:

Would it be possible to change this to show the name of that scheme as well? I'd be more than happy to submit a PR if that's the case.

Integrate with Danger.swift file

Does this plugin work with Dangerfile.swift not the usual Dangerfile? If so, how can I accomplish this?

Impossible to use with Danger 2.1.1

I guess the gem dependency needs to be updated, it doesn't look like there are breaking changes on danger though from 2.0 to 2.1

Bundler could not find compatible versions for gem "danger":
  In Gemfile:
    danger (= 2.1.1)

    danger-xcov (= 0.2.0) was resolved to 0.2.0, which depends on
      danger (~> 2.0.0)

'Invalid Dangerfile' after Fastlane 2.172.0 update

In one of our projects after upgrading to fastlane 2.172.0 we are getting an error:

[!] Invalid Dangerfile file: Could not find option skip_package_dependencies_resolution in the list of available options: 
workspace, project, scheme, configuration, source_directory, derived_data_path, xccov_file_direct_path, output_directory,

include_targets, only_project_targets, disable_coveralls, coveralls_service_name, coveralls_service_job_id, 
coveralls_repo_token, xcconfig, ideFoundationPath, legacy_support

Our Dangerfile does not specify skip_package_dependencies_resolution key.
After downgrading fastlane to 2.171.0 the issue is gone.
Is it an issue with Fastlane or danger-xcov needs to be updated to accomodate new changes?

Versions we are using:

danger 8.2.2
fastlane 2.172.0
xcov 1.7.5
danger-xcov 0.5.0
xcode 12.3

Add Support for Xcode 11 xcresult & xccovreport

With Xcode 11, Apple has changed up the file format of xcresult so that you can't simply inspect into the xcresult's file structure. Instead, you need to go through their tool xcresulttool in order to retrieve files like xccoverage out of the xcresult.

Improve handling a missing .xccoverage file

Hi, when there are failing unittests, there won't be a .xccoverage file generated by Xcode. Therefore, the error raised by xcov will be passed through to Danger resulting in Danger exiting with status code 1 instead of 0. This causes that danger will only print a quite generic error message instead of the rest of the report:

In case the xcode_summary step is used, the rest of the report might even contain the failed unittests, which are now hidden to the contributors.

What do you think about adding a rescue statement to danger-xcov to handle the error gracefully and print the error message as failure in the danger report? I can create a PR if you agree with this idea.

Failed to export xccovreport from xcresult

but there is a xcresult file in the path. Any idea?

Dangerfile doesn't work

HI, I'm trying to implement danger on our CI ecosystem but at the moment of execute danger with xciv it fails with this error

[!] The exception involves the following plugins:

• danger-xcov
  bundler: failed to load command: danger (/Users/vagrant/git/vendor/bundle/ruby/2.6.0/bin/danger)
  Danger::DSLError:

  from Dangerfile:3

scheme: Grability,

Future-proofing

In an upcoming version of Danger, I'm going to be adding linting to the plugin - specifically because I'll be building a website for all plugins. You can see the idea here: danger/danger#223

Effectively, you just need to add some description bits and pieces to the docs for the class: https://github.com/dbgrandi/danger-proselint/blob/master/lib/danger_plugin.rb#L3-L17

( I'm still figuring the exacts there, but it'll probably be after WWDC now )

xcov overall coverage report including ignore files and showing wrong coverage

I have moved from xcov 1.3.5 to latest version(1.5.1)

I am noticing now that overall coverage which also including coverage of ignore files and showing wrong coverage?

Any way to solve it?

Test coverage shows 0.00%

Hi! We're using the danger plugin and we're having an intermittent problem where it says that test coverage for our app (and all files) is 0.00%. It seems to happen for about half of all builds

Here's the log from Danger (running on CircleCI) for a case where it showed 0.00% -> seems like it shows success?

danger 3

Could you please update the gem spec to support danger 3.x.x ?

At the moment when Danger 3 is specified in the gem file an old version of danger-xcov is installed (0.1.2)

Thank you

Is it need maintain xcov_report folder

How danger-xcov get generated xcov data?

Invalid xcodebuild command execution on Xcode Bots CI

Hi, thanks for the plugin, I've just tried to integrate it with my project and using the Xcode Bots CI + @buildasaur, and the danger trigger failed with the following log:

Skipping file blacklisting as no ignore file was found at path
xcodebuild -list -workspace ios-merchant.xcworkspace�
xcodebuild clean -showBuildSettings -workspace ios-merchant.xcworkspace -scheme AFNetworking�

As I can see here it's trying to build the AFNetworking scheme although in the dangerfile I specified to build another one:

xcov.report(
   scheme: 'ios-merchant-staging',
   workspace: 'ios-merchant.xcworkspace',
   minimum_coverage_percentage: 50
)

@nakiostudio any idea? 😄

Unable to find any .xccoverage file

I've combed through previous issues regarding this error message but none of the resulting releases have worked for me. The only solution that does work is providing the path to the Derived Data folder when running xcov but I have the default Derived Data path set in Xcode

danger-xcov plugin keep complaining about the missing xccoverage file.

I have tried to use the danger-xcov plugin but I am stuck with this error. This issue is not happening in the main xcov tool https://github.com/fastlane-community/xcov but its happening in the danger plugin.

[18:39:31]: Unable to find any .xccoverage file.
[18:39:31]: Make sure you have enabled 'Gather code coverage' setting on your scheme settings.
[18:39:31]: Alternatively you can provide the full path to your .xccoverage file.

I am using Xcode 13 and I have provided the full path of xcresult which worked with just xcov but not with the danger-xcov

 report = xcov.produce_report(workspace: ENV['XCWORKSPACE'],
      scheme: ENV['SCHEME'],
      minimum_coverage_percentage: 90.00,
      xccov_file_direct_path: ENV['DANGER_XCRESULT_DIRECTORY'], 
      markdown_report: true)

xcov.output_report(report)#

where xcresult path is defined in the .env file export DANGER_XCRESULT_DIRECTORY="fastlane/test_output/$SCHEME.xcresult"

Issues

• First issue that I see is xcov is not able to pick up the scheme even after I have provided the scheme and workspace details in the parameter.
• Second it's throwing the error I have pointed out above.

Not working anymore with Fastlane 2.86.0
