      const response = await fetch(
        `https://api.openweathermap.org/data/2.5/weather?q=${location}&units=${units}&appid=${this.config.apiKey}`
      );

      const data = await response.json();

      return {

  });

  it('should execute successfully with valid parameters', async () => {
    const result = await skill.execute({
      location: 'London',
      units: 'metric'
    });

    assert(result.success === true);
    assert(result.data.location === 'London');
  });

  it('should handle invalid location', async () => {
    const result = await skill.execute({
