如何在 TypeScript 中使用 Mocha 和 Jest 而不发生冲突？

我正在尝试在一个项目上安装带有类型的 Mocha 和 Jest。我们使用严格的类型检查，因此我收到与冲突的全局类型相关的错误。

我试图创建不明确的模块声明，仅定义 Mochatypes at tsconfig。我一直在尝试删除 Jest 的声明 - 但这会有部分帮助。禁用严格类型检查或库检查不是一个选项。

我本来希望能够正常工作，但结果却出现了下一个错误。

node_modules/@types/jest/index.d.ts(29,13): error TS2403: Subsequent variable declarations must have the same type.  Variable 'beforeEach' must be of type 'HookFunction', but here has type 'Lifecycle'.
node_modules/@types/jest/index.d.ts(31,13): error TS2403: Subsequent variable declarations must have the same type.  Variable 'afterEach' must be of type 'HookFunction', but here has type 'Lifecycle'.

node_modules/@types/node/globals.d.ts(926,15): error TS2430: Interface 'Global' incorrectly extends interface 'MochaGlobals'.
  Types of property 'describe' are incompatible.
    Type 'Describe' is not assignable to type 'SuiteFunction'.
      Types of property 'only' are incompatible.
        Type 'DescribeBase' is not assignable to type 'ExclusiveSuiteFunction'.
          Type 'void' is not assignable to type 'Suite'.

即使从 Jest 中删除所有类型也会出现此错误：

node_modules/@types/node/globals.d.ts(926,15): error TS2430: Interface 'Global' incorrectly extends interface 'MochaGlobals'.
  Types of property 'describe' are incompatible.
    Type 'Describe' is not assignable to type 'SuiteFunction'.
      Types of property 'only' are incompatible.
        Type 'DescribeBase' is not assignable to type 'ExclusiveSuiteFunction'.
          Type 'void' is not assignable to type 'Suite'.

截至 2019 年 8 月，此问题似乎已修复master https://github.com/facebook/jest/pull/8571，但新版本尚未发布。

与此同时，我能够通过将以下内容添加到我的定义之一来解决这些错误：

declare module '@jest/types/build/Global' {
  interface DescribeBase extends mocha.SuiteFunction {}
  interface ItBase extends mocha.TestFunction {}
}
