使用 Chutzpah 的简单 TypeScript 测试不起作用

Question

我正在尝试使用 Jasmine 和 Chutzpah 运行最基本的 TypeScript 测试，但我无法让它工作。这是源文件：

class Simple {
    public easyTest() {
        return 5;
    }
}

这是规范：

/// <reference path="../../../scripts/typings/jasmine/jasmine.d.ts" />
/// <reference path="../../../src/typescript/classSimple.ts" />
describe("Simple Calculations", () => {
    it("should return true", () => {
        var simpl = new Simple();
        expect(simpl.easyTest()).toBe(5);
    });
});

这是我的 chutzpah.json 文件：

{
    "RootReferencePathMode": "SettingsFileDirectory",
    "Framework": "jasmine",
    "Compile": {
        "Mode": "External",
        "Extensions": [ ".ts" ],
        "ExtensionsWithNoOutput": [ ".d.ts" ]
    },
    "References": [        
        { "Path": "../../../src/typescript/classSimple.ts" }        
    ],
    "Tests": [
        { "Path": "simpleSpec.ts" }
    ],
    "EnableTracing": true
}

这是文件夹结构

TestProject.sln
-src
--typescript
---classSimple.ts
-tests
--jasmine
---typescript
----chutzpah.json
----simpleSpec.ts

此 VS.NET 项目设置为在保存时编译 TypeScript 我正在查看转译后的 JavaScript 输出：classSimple.js 接下来在完全相同的目录中至 classSimple.ts。然而，当我运行使用 Chutzpah 的规范时，我得到以下信息：

Message:Chutzpah run started in mode Execution with parallelism set to 4 Message:Building test context for C:\dev\TestProject\tests\jasmine\typescript\simpleSpec.ts Message:Building test context for 'C:\dev\TestProject\tests\jasmine\typescript\simpleSpec.ts' Message:Test file c:\dev\TestProject\tests\jasmine\typescript\simplespec.ts matched test file path from settings file Message:Investigating reference file path '../../../src/typescript/classSimple.ts' Message:Added file 'C:\dev\TestProject\src\typescript\classSimple.ts' to referenced files.

就是这样 - 它只是在最后切断，没有任何反应。问题是，我看到 .js 文件正好在上面跟踪中所述的位置，但 Chutzpah 声称 Couldn't find generated path for ...

这对于单元测试来说非常简单。我知道测试独立于 .ts 文件工作，因为如果我运行只有 .js 文件测试通过。

我做错了什么？

感谢您发布非常详细的重现。你遇到了我见过几次的问题。由于您的 chutzpah.json 嵌套在您的测试文件夹中，您需要指定 chutzpah 应该使用的文件夹路径映射来确定如何从源映射到输出文件夹。为此，只需将 chutzpah.json 更改为：

{
    "RootReferencePathMode": "SettingsFileDirectory",
    "Framework": "jasmine",
    "Compile": {
        "Mode": "External",
        "Extensions": [ ".ts" ],
        "ExtensionsWithNoOutput": [ ".d.ts" ],
        "Paths": [
            { "SourcePath": "../../../", "OutputPath": "../../../"}
        ]
    },
    "References": [        
        { "Path": "../../../src/typescript/classSimple.ts" }        
    ],
    "Tests": [
        { "Path": "simpleSpec.ts" }
    ],
    "EnableTracing": true,
    "TraceFilePath": "trace.txt"
}

另一种解决方法是将 chutzpah.json 放在项目的根目录下。

我需要考虑改进 Chutzpah 以避免这种情况。我想我会考虑在这种情况下让 chutzpah 假设文件位于同一位置以避免这种常见的陷阱。

Google 把我带到这里来解决类似的问题：

我的 Chutzpah 项目中的一些新测试是用 TypeScript 编写并编译成单个 outfile:

tsconfig.json

  "compilerOptions": {
    "noImplicitAny": true,
    "target": "es5",
    "module": "none",
    "outFile": "./Tests/mytests-ts.js",
    "sourceMap": true
  }

Chutzpah 找不到 *.ts 个文件

Chutzpah Error: System.IO.FileNotFoundException: Couldn't find generated path for D:\Code\ChutzpahProject\Scripts\DateServiceMock.ts

直到我使用 Paths 选项：

chutzpah.json

  "Compile": {
    "Extensions": [ ".ts" ],
    "ExtensionsWithNoOutput": [ ".d.ts" ],
    "Executable": "build-ts.cmd",
    "Paths": [
      { "OutputPath": "Tests/mytests-tests-ts.js" }
    ]
  },

感觉这可能是对@matthew-manela 的回答的评论...我想。
