This project-based course is a detailed guide to web application development using the increasingly popular Flask framework.

Flask is known for being simple, lightweight and having a small learning curve. If you've got some experience in Python, picking up Flask will be a breeze. It's got a booming job market and will put you on track to becoming an in-demand full-stack developer. What's not to love?

Flask: Develop Web Applications in Python

The complete implementation of the problem is provided below. Let's take a look at it!
# Solution

"""Flask Application for Paws Rescue Center."""
from flask import Flask, render_template
app = Flask(__name__)


@app.route("/")
def homepage():
    """View function for Home Page."""
    return render_template("home.html")


@app.route("/about")
def about():
    """View function for About Page."""
    return render_template("about.html")


if __name__ == "__main__":
    app.run(debug=True, host="0.0.0.0", port=3000)


import React from 'react';
import { shallow, configure } from 'enzyme';
import Adapter from 'enzyme-adapter-react-16';

configure({ adapter: new Adapter() });

import HelloWorld from './app';

var TestResult = function() {
    this.succeeded = false;
    this.reason = "";
    this.input = "";
    this.expected_output = "";
    this.actual_output = "";
}

export const executeTests = function() {

  var results = [];

  result = new TestResult();
  result.input = 'HelloWorld Component';
  result.expected_output = "span containing text 'Hello World'"

  let wrapper = shallow(<HelloWorld />);

  // Call your Challenge function here.

  let type = wrapper.type();
  let testSuccessful = true;
  let failureReason;

  if (type !== 'span') {
    testSuccessful = false;
    failureReason = "You need to render exactly one span HTML element";
  } else if (wrapper.props().children != "Hello World") {
     testSuccessful = false;
     failureReason = "You have rendered wrong message in your span element";
  }

  result.actual_output = wrapper.html();

  if (testSuccessful) {
    result.succeeded = true;
    result.reason = "Succeeded"
  } else {
    result.succeeded = false;
    result.reason = failureReason;
  }

  results.push(result);

  return results;
}

# Explanation
In this solution, we have made the following improvements to the application:

- First, we replaced the template logic from views to inside the `<body>` tag of the corresponding `HTML` files.
- We also added titles in each template using the `<title>` tag. 
- Then, we imported the `render_template` function in **line #2** of `app.py`.
- Afterward, we passed the appropriate template name into the `render_template()` function (i.e `home.html` and `about.html` respectively).
- The *views*  return the value returned by the `render_template()` function instead of a `String` as shown in **line #9** and **#15**.

In this lesson, we will look into the solution of the challenge given in the previous lesson.
