Hello.

+1 about this issue.

I currently use this command line to run unit test. I'ld like to use the XCode Plugin instead.

xcodebuild -workspace 'myproject.xcworkspace' -scheme "myprojectTests" -destination "name=iPhone 11,OS=13.3" -enableCodeCoverage YES ONLY_ACTIVE_ARCH=YES  test

So i have the same issue while launching with plugin DSL method :

xcodeBuild(
xcodeSchema: "myprojectTests",
xcodeName: 'latest',
configuration: 'Debug',
xcodeWorkspaceFile: 'myproject',
sdk: 'iphonesimulator13.2',
xcodebuildArguments: "test -destination \"name=iPhone 11\" -enableCodeCoverage YES",
resultBundlePath: 'test-result',
)

In fact, by default, the "build" parameters is added in xcodebuild command instead of "test". 

Can you confirm this is an issue ?

I can eventually fix and create a PR to fix this issue.

Thank you.

Yes, I believe this IS the issue. The doc mentions that you pass on the test target/scheme to the same build plugin but ideally this runs it as a build and not test. 

Have you tried using the xcodebuildArguments to specify "-workspace 'myproject.xcworkspace' -scheme "myprojectTests" -destination "name=iPhone 11,OS=13.3" -enableCodeCoverage YES ONLY_ACTIVE_ARCH=YES  test" keeping everything else blank? 

urmil025 i am facing issue generating unit test report. Everything is configured properly as per document but still i am getting this "Recording test results None of the test reports contained any result".

Jenkins version: 2.289.1

Xcode: 12.5

Your help would be really appreciated.

pinkeshgjr Are you using Junit? It is quite possible that Junit is not able to detect the test outputs and hence reports that there are no test results. 

I have added this to my xcodebuild CLI command which reports the results in the format that is required by Jenkins. See if this helps. 

xcodebuild ... | xcpretty --report junit && exit ${PIPESTATUS[0]}'

Just add  

-allowProvisioningUpdates -enableCodeCoverage YES ONLY_ACTIVE_ARCH=YES test -list | xcpretty --report junit && exit ${PIPESTATUS[0]}

This will need you to have xcpretty installed on the machine. Find more details here - https://github.com/xcpretty/xcpretty 

urmil025 i just tried replacing command that you shared also installed xcpretty with this command 

gem install xcpretty.

Still getting same error, do i need to adding any plugin?

What is your full command? Also, try running only

 xcpretty --help

in your build and see if Jenkins recognizes it. you might need to specify the entire path or add it to your bash file. 

urmil025 i just tried adding xcpretty --help and Jenkins recognise it. There is no command --report

I don't know how you installed it but I am running xcpretty with --report option and it is just fine. Try doing so locally, running the entire command with xcpretty, and see if that helps. 

urmil025 I am using Jenkins locally. I tried adding -r junit in Custom xcodebuild arguments. Still same error, lool like xcpretty is not working with Jenkins. Is there any additional setup have you done?

-allowProvisioningUpdates -enableCodeCoverage YES ONLY_ACTIVE_ARCH=YES test -list | xcpretty --report junit && exit ${PIPESTATUS[0]}

urmil025 i just removed xcode from jenkins and added execute shell command in configuration and it works fine.

xcodebuild -workspace myproject.xcworkspace -scheme myprojectTests -destination 'platform=iOS Simulator,name=iPhone 12 Pro' -enableCodeCoverage YES test | xcpretty --report junit && exit ${PIPESTATUS[0]}

Now i am facing some other issue like below. 
xcodebuild[99034:318512] NSFileHandle couldn't write. Exception: *** -[_NSStdIOFileHandle writeData:]: Broken pipe

That seems to be something in your code. I see some solutions on Stackoverflow. 

urmil025 There was issue with path. It works fine now but is there any way to generate code coverage report?

xcodebuild -workspace MyProject.xcworkspace -scheme MyProjectTests -destination 'platform=iOS Simulator,name=iPhone 12 Pro' -derivedDataPath DerivedData/ -enableCodeCoverage YES test | /usr/local/bin/xcpretty --report junit --output test-reports/reports.xml && exit ${PIPESTATUS[0]}
