ios - 生成 iOS/Swift 代码覆盖率测试报告

Question

Code coverage in Xcode is a testing option supported by LLVM. When you enable code coverage, LLVM instruments the code to gather coverage data based on the frequency that methods and functions are called. The code coverage option can collect data to report on tests of correctness and of performance, whether unit tests or UI tests.

我想通过 Xcode 生成代码覆盖率报告。

我看过 gcovr http://gcovr.com 。
...或者通过 xcodebuild 生成报告更为谨慎？

是否有通过 Xcode 8+ 生成报告的教程或指南？

Answer 1

xcodebuild 有 -enableCodeCoverage YES 选项。您可以通过输入 xcodebuild --help 轻松查看 xcodebuild 命令的可能性。

以下是 Apple 关于代码覆盖率使用的指南:https://developer.apple.com/library/content/documentation/DeveloperTools/Conceptual/testing_with_xcode/chapters/07-code_coverage.html

您甚至可以直接从 Xcode 查看覆盖率报告。
