使用 Travis 进行 Swift CI 测试 - 测试运行程序在开始测试执行之前退出

Question

我最近开始实施 Travis，但无法正常工作。 当我在本地运行测试时，它们会成功。

谁能帮助我如何让它正常工作？

.travis.yml

language: swift
osx_image: xcode10.1
script:
  - xcodebuild -scheme sample -workspace sample.xcodeproj -sdk iphonesimulator -destination 'platform=iOS Simulator,name=iPhone 7,OS=10.1' build test

样本测试

class sampleTests: XCTestCase {

    func testThis() {
        XCTAssertTrue(true)
    }
}

错误：

Done. Your build exited with 1.

Answer 1

Xcode 10 中引入的新构建系统的 UI 测试存在一些问题。您应该添加 -UseModernBuildSystem=NO。

我使用的完整脚本是：

- xcodebuild -workspace sample.xcworkspace -scheme sample -sdk iphonesimulator12.1 -destination "platform=iOS Simulator,OS=12.1,name=iPhone Xs Max" -UseModernBuildSystem=NO test | xcpretty --test --color; test ${PIPESTATUS[0]} -eq 0

请注意，我还使用 xcpretty，并带有一些参数以确保日志不会变得冗长。最后一部分是确保构建失败以防测试失败。

希望对你有帮助！
