ios - 测试在 Xcode 中通过，但在 Circle CI 中失败

问题:对于this pull request ，测试没有通过 CircleCI，但测试在本地通过。为什么？

---

CircleCI test output显示所有 FBSnapshotTestCase 测试的失败。例如:

✗ testAdjustsFontSizeToFitWidth, ((comparisonSuccess__) is true) failed - Snapshot comparison failed: Error Domain=FBSnapshotTestControllerErrorDomain Code=1 "Unable to load reference image." UserInfo=0x7f85f36b0a50 {NSLocalizedFailureReason=Reference image not found. You need to run the test in record mode, NSLocalizedDescription=Unable to load reference image., FBReferenceImageFilePathKey=/Users/distiller/TTTAttributedLabel/Example/TTTAttributedLabelTests/ReferenceImages_32/TTTAttributedLabelTests/[email protected]}

[…]

✗ testAttributedTruncationToken, ((comparisonSuccess__) is true) failed - Snapshot comparison failed: Error Domain=FBSnapshotTestControllerErrorDomain Code=1 "Unable to load reference image." UserInfo=0x7f85f35b06d0 {NSLocalizedFailureReason=Reference image not found. You need to run the test in record mode, NSLocalizedDescription=Unable to load reference image., FBReferenceImageFilePathKey=/Users/distiller/TTTAttributedLabel/Example/TTTAttributedLabelTests/ReferenceImages_32/TTTAttributedLabelTests/[email protected]}

但是，相同的测试在本地通过:

在 CircleCI 上，测试使用不存在的 ReferenceImages_32 目录:

/Users/distiller/TTTAttributedLabel/Example/TTTAttributedLabelTests/ReferenceImages_32/TTTAttributedLabelTests/[email protected]

但是，图像确实存在于 ReferenceImages_64 中。我希望使用 _64 目录，因为 circle.yml 文件指定使用 iPhone 6 模拟器:

dependencies:
  pre:
    - xcrun instruments -w "iPhone 6 (8.3 Simulator)" || exit 0
  override:    
    - sudo gem install cocoapods xcpretty obcd -N
    - pod install --project-directory=Example
test:
  override:
    - set -o pipefail && xcodebuild -workspace 'Example/Espressos.xcworkspace' -scheme 'Espressos'
      -sdk iphonesimulator -destination "platform=iOS Simulator,name=iPhone 6"
      GCC_INSTRUMENT_PROGRAM_FLOW_ARCS=YES GCC_GENERATE_TEST_COVERAGE_FILES=YES clean test | xcpretty -c
      --report junit --output ${CIRCLE_TEST_REPORTS}/junit.xml

• 这是什么原因造成的？
• 如何在 CircleCI 上通过测试？
• 可能相关:this FBSnapshotTestCase issue
