xcresultparser

Overview

Parse the binary xcresult bundle from Xcode builds and test runs.

Interpret binary .xcresult files and print summary in different formats:

• txt
• colored command line output
• xml
• junit
• cobertura
• html
• markdown
• warnings
• errors

In case of 'xml' JUnit format for test results and generic format (Sonarqube) for coverage data is used.

You can also specify the name of the project root. Paths and urls are then relative to the specified directory. (used for urls in xml output)

This tool can read test result data and code coverage data from an .xcarchive using the developer tools included in Xcode 13. Namely here: xcresulttool and xccov to get json data from .xcresult bundles.

Parsing the JSON is done using the great XCResultKit package.

Converting code coverage data

~~Unfortunately converting to the coverage xml format suited for e.g. sonarqube is a tedious task. It requires us to invoke the xccov binary for each single file in the project.~~

~~First we get a list of source files with coverage data from the archive, using xccov --file-list and then we need to invoke xccov for each single file. That takes a considerable amount of time. So at least we can spread it over different threads, so that it executes in parallel and is overall faster.~~

~~Until now we used xccov-to-sonarqube-generic.sh which does the same job, just in a shell script. It has the same problem and since it can not spawn it to different threads, it takes about 5x the time.~~

It used to be like described above up until Xcode 13. Xcode 13 brought a new version of the xccov commandline tool, which now can output the entire coverage data at once. No more tedious task of calling into xccov for each single swift file! Therefore the shell script xccov-to-sonarqube-generic.sh provided by sonar does the job in the same time as xcresultparser. That renders the initial purpose of this tool useless. However, xcresultparser meanwhile can do a few more tricks, than only converting coverage data from a xcresult bundle to xml suited for sonarqube.

It my still be useful for you, if you want to just display the contents of the xcresult bundle (the tests) in a terminal, as html or as markdown for your build chain.

It can also be used for cobertura, thanks to the collaboration of Thibault Wittemberg and maxwell-legrand.

Furthermore it can extract testdata from the xcresult bundle in junit format, also suited for sonarqube.

                          case of 'xml' sonar generic format for test results
                          and generic format (Sonarqube) for coverage data is
                          used. In the case of 'cobertura', --coverage is
                          implied.
  -p, --project-root <project-root>
                          The name of the project root. If present paths and

  -t, --coverage-targets <coverage-targets>
                          Specify which targets to calculate coverage from. You
                          can use more than one -t option to specify a list of
                          targets.
  -s, --summary-fields <summary-fields>
                          The fields in the summary. Default is all:

  -c, --coverage          Whether to print coverage data.
  -n, --no-test-result    Whether to print test results.
  -f, --failed-tests-only Whether to only print failed tests.
  -q, --quiet             Quiet. Don't print status output.
  -i, --target-info       Just print the targets contained in the xcresult.
  -v, --version           Show version number.
  -h, --help              Show help information.

Now that a copy of xcresultparser is in your search path, delete it from your desktop.

You're ready to go! 🎉

How to use it

The tool doesn't create any file. It justs outputs its results to standard out. It is up to you to write the output to a file, using redirection. For example, if you want to write the text output into a file named output.txt on your desktop:

xcresultparser -o txt test.xcresult > ~/Desktop/output.txt

However, if all you need is to output the contents of the xcresult bundle to the terminal:

xcresultparser -o cli test.xcresult

You can also merge two xcresult files with:

xcrun xcresulttool merge Result1.xcresult Result2.xcresult --output-path=Result_merged.xcresult

With xcresultparser >= 1.5.2 you can now call: xcresultparser Result_merged.xcresult --output-format=junit

It iterates through all available test actions It creates a test suite for each test action It sets the overall test time of the testsuites to the sum of all test suite times.

Examples

Colored CLI output

Print the test results in color to the command line:

xcresultparser -o cli test.xcresult

HTML output

Create a single html file with test data

xcresultparser -o html test.xcresult > testResult.html

Junit output

Create an xml file in JUnit format:

xcresultparser -o junit test.xcresult > junit.xml

Sonarqube output

Create an xml file in generic test exectuion xml format:

xcresultparser -o xml test.xcresult > sonarTestExecution.xml

Create an xml file in generic code coverage xml format for all targets:

xcresultparser -c -o xml test.xcresult > sonarCoverage.xml

Create an xml file in generic code coverage xml format, but only for two of the targets "foo" and "baz":

xcresultparser -c -o xml test.xcresult -t foo -t baz > sonarCoverage.xml

Cobertura XML output

Create xml file in Cobertura format:

xcresultparser -o cobertura test.xcresult > cobertura.xml

Note that some data in this file is currently fake as of this time of writing, but should have accurate line coverage information. It should be good enough for importing into tools like GitLab coverage visualizer.

It may be desirable to also pass --project-root if you wish to alter the filenames and sources in the Cobertura report (see note below) - this is required for GitLab compatbility.

Markdown output

Simple markdown formatting for test results. (We use it for display in a Teams Webhook)

xcresultparser -o md test.xcresult > teamsWebhook.txt

Code Climate output

JSON output for Code Climate checks

xcresultparser -o warnings test.xcresult > climate.json

Error output

JSON output describing errors

xcresultparser -o errors test.xcresult > errors.json

About paths for the sonarqube scanner

The tools to get the data from the xcresult archive yield absolute path names. So you must provide an absolute pathname to the sonar.sources paramater of the sonar-scanner CLI tool and it must of course match the directory, where xcodebuild ran the tests and created the .xcresult archive.

If you want to use the test results for sonarqube, there is another twist: the .xcresult bundle only lists the test by testclass, but not by file. However sonarqube expects the file paths of the tests. In this case you must provide a --project-root to xcresultparser. Only then xcresultparser can convert the classnames to file names, by grep-ing for "class NameOfClass". If such a file is found in the directory provided in --project-root, then the file path can be detrmined and the sonar-scanner happily can scan the files for tests.

In cases where the xcresult archive is not created on the same machine and the paths used for sonar-scanner differ, the pathnames need to be adjusted. In such a case you can use a relative path for the sonar.sources paramater of the sonar-scanner CLI tool and convert the output of xcresultparser to also return relative path names. The parameter -p or --project-root takes a string in order to find and delete the beginning of the pathnames, so they are relative. The way this is done is let's say pretty naiv… The string provided with --project-root is searched in the absolute path and, if found, the path is chopped up to and including the provided string. Example: ./xcresultparser -c -o xml --project-root "work/myApp/" test.xcresult > sonar.xml Example path in xcresult: /Users/alex/work/myApp/Sources/myApp/SomeClass.swift will be converted to: Sources/myApp/SomeClass.swift Now make sure you call sonar-scanner from within the root of your project and use the relative path "Sources" as parameter for sonar.sources.
