在Angular中使用TypeScript对文件大小进行Jasmine单元测试

import { Injectable } from '@angular/core';

@Injectable()
export class FileSizeService {
  getFileSize(filePath: string): number {
    // 在这里实现获取文件大小的逻辑
    return 0;
  }
}

import { TestBed } from '@angular/core/testing';
import { FileSizeService } from './file-size.service';

describe('FileSizeService', () => {
  let service: FileSizeService;

  beforeEach(() => {
    TestBed.configureTestingModule({});
    service = TestBed.inject(FileSizeService);
  });

  it('should return the correct file size', () => {
    const filePath = 'path/to/file.txt';
    const fileSize = service.getFileSize(filePath);
    expect(fileSize).toBeGreaterThan(0);
  });
});
