FBSnapshotTestCase image not found while running Xcode test

Question

Can't figure out why report FBSnapshotTestCase image not found while running Xcode test.

I tried to link FBSnapshotTestCase in Target ChartTests, but still seeing the same error.

I am not familiar with this, can anyone help? Thank in advance.

To reproduce:

Download the project from https://github.com/danielgindi/Charts

navigate to the project root,

1. (optional) run carthage bootstrap to install dependency. The project has a dependency check, so if you don't run this, it will run it when launching the test.

2. enter

   xcodebuild -project 'Charts.xcodeproj' -scheme 'ChartsTests' -configuration 'Debug' -sdk iphonesimulator -destination id='E40B5365-EF82-430D-A767-2A37995CCEE1' clean build test

the destination id could be any uuid of the simulator on the machine.

Then it reports:

Answer 1

It turned out I need to add run script in Build phases, and let carthage copy the frameworks:

copy from https://github.com/Carthage/Carthage#if-youre-building-for-ios-tvos-or-watchos:

On your application targets’ “Build Phases” settings tab, click the “+” icon and choose “New Run Script Phase”. Create a Run Script in which you specify your shell (ex: /bin/sh), add the following contents to the script area below the shell:

/usr/local/bin/carthage copy-frameworks

and add the paths to the frameworks you want to use under “Input Files”, e.g.:

$(SRCROOT)/Carthage/Build/iOS/FBSnapshotTestCase.framework
