haskell - 堆栈运行单一基准测试

Question

我在 cabal 文件中定义了多个基准:

benchmark my-gauge-bench
  type: exitcode-stdio-1.0
  main-is: Main.hs
  hs-source-dirs:
      bench/gauge
  ghc-options: -Wall -Wcompat -Wincomplete-record-updates -Wincomplete-uni-patterns -Wredundant-constraints -Wall -threaded -rtsopts -with-rtsopts=-N
  build-depends:
      QuickCheck
    , base >=4.10 && <10
    , bytestring
    , gauge
  default-language: Haskell2010

benchmark my-weigh-bench
  type: exitcode-stdio-1.0
  main-is: Main.hs
  other-modules:
      Paths_pkg_core_gen
  hs-source-dirs:
      bench/weigh
  ghc-options: -Wall -Wcompat -Wincomplete-record-updates -Wincomplete-uni-patterns -Wredundant-constraints -Wall
  build-depends:
      QuickCheck
    , base >=4.10 && <10
    , bytestring
    , weigh

如何使用 Stack 只运行单个基准测试(例如 my-guage-bench)？

Answer 1

这适用于堆栈中的所有目标，无论是测试、基准测试还是可执行文件。

堆栈中有一个很酷的小命令，可以帮助您列出所有可用目标，而无需通过 my-package.cabal 或 package.yaml 文件进行挖掘。它对于多包项目特别有用，并且适用于 stack.yaml 的 packages: 字段中列出的所有包:

$ stack ide targets
my-package:lib
my-package:test:doctests
my-package:test:tests
my-package:bench:weight
my-package:bench:gauge
another-package:lib
another-package:exe:my-cool-executable
another-package:test:doctests
another-package:test:tests
another-package:bench:weight
another-package:bench:criterion

现在我们知道了可以调用特定基准的列表

$ stack bench my-package:bench:gauge another-package:bench:criterion
