NativeScript 测试无法运行答案

【问题描述】：

测试似乎在模拟器中运行，因为应用程序会短暂启动并显示“正在测试”然后是“总计：0，通过：0，失败：0”的文字（拍摄了模拟器窗口的视频）。

这是一个使用 TypeScript 的 NativeScript Angular 项目。我已经尝试了src/app/tests/example.js 和src/app/tests/example.ts 的示例，其中包含以下内容：

// A sample Jasmine test
describe('A suite', () => {
  it('contains spec with an expectation', () => {
    expect(true).toBe(true);
  });
});

运行tns test ios 后的最后几行日志。

【解决方案1】：

我将测试放在错误的文件夹中。试过src/tests 和src/app/tests。注意到app/tests 被提及但认为它意味着src/app。

注意tns test init 没有在app/tests 中创建任何文件。
