unit-testing - 使用 Chutzpah 进行简单的 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，我正在实际查看转译的 JavaScript 输出:classSimple.js 在 classSimple.ts 旁边的完全相同的目录中。然而，当我使用 Chutzpah 运行规范时，我得到以下结果:

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 - 它只是在最后被切断，什么也没有发生。问题是，我在上面跟踪中指定的位置完全看到了 .js 文件，但 Chutzpah 声称​​无法找到 .. .

这与单元测试一样简单。我知道测试的工作独立于 .ts 文件，因为如果我只运行 .js 文件，测试就会通过。

我做错了什么？

感谢您发布非常详细的重现。您遇到了我已经见过几次的问题。由于 chutzpah.json 嵌套在测试文件夹中，因此您需要指定 chutzpah 应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"
}

另一个解决方法是将 chutzpah.json 放在项目的根目录下。

我需要研究如何让Cuttzpah变得更好以避免这种情况。我想我会考虑在这种情况下让大胆假设文件位于同一位置以避免这种常见的陷阱。
