Describe the feature you want to add

Currently, during the scripting phase, it is not possible to get interpolated values.

For example: req.getUrl() will return {{baseURL}}/users/{{userId}} instead of localhost:3000/users/123.

I believe it's better to have these values interpolated by default. Or at least provide both options.

Mockups or Images of the feature

For two options:

  getUrl() {
    return this.req.url;
  }

  getInterpolatedUrl() {
    return interpolateString(this.req.url);
  }

Or by default:

  getUrl() {
    return interpolateString(this.req.url);
  }
