Can't read Xcode log file

[ilyapuchka]

When I'm trying to read log file generated by fastlane I see the following error

cat ~/Library/Logs/scan/babylon-Babylon.log | xcpretty -f "xcpretty-json-formatter"

The command that fastlane scan executes is following:

set -o pipefail && env NSUnbufferedIO=YES xcodebuild -workspace ./Babylon.xcworkspace -scheme Babylon -configuration Debug -destination 'platform=iOS Simulator,id=BB4396A6-7293-4863-88DC-15A38A801E1E' -derivedDataPath '/Users/ilya.puchka/Library/Developer/Xcode/DerivedData/Babylon-cganrmibthibvkepvoondhopatcw' build test | tee '/Users/ilya.puchka/Library/Logs/scan/babylon-Babylon.log' | xcpretty -f `xcpretty-json-formatter` --report html --output '/Users/ilya.puchka/dev/babylon-ios/fastlane/test_output/report.html' --report junit --output '/Users/ilya.puchka/dev/babylon-ios/fastlane/test_output/report.junit' --report junit --output '/var/folders/28/cn8n570x0bs_hzvsyl0yd4d891kn2m/T/junit_report20180617-44360-1okexpn'

After this is run I do get json report file, but it does not contain expected test failures, only warnings and test summary messages.

You need to use backticks when running xcpretty:

cat ~/Library/Logs/scan/babylon-Babylon.log | xcpretty -f `xcpretty-json-formatter`

Are the test failures showing up on the html or junit reports?

[ilyapuchka]

I got -bash: xcpretty-json-formatter: command not found error when I'm trying to do that, but that was because I had installed xcpretty-json-formatter via bundler, installing it system wide solved it.
Yes, test failures are in report.html, but they don't appear in json.

It's hard to investigate without the log or a repro example. It'd be really helpful if you could upload it or send to me privately so I can take a closer look.

I solved this error by reinstall xcpretty-json-formatter
