restful-booker

A simple Node booking form for testing RESTful web services.

Installation

In order to run restful booker you will need to install:

1. npm and node
2. mongo db

From this folder you should then be able to execute:

npm install
npm start

Restful booker should then start running on localhost and you can access it from a browser.

Swagger documentation

API documentation with Swagger can be found on Swagger when the application is running.

Unit Tests

There are some unit tests in the /tests folder. Run these tests:

npm test

Integration tests with TextTest

In order to run the TextTest integration tests in the folder 'integration_tests' you will need to install:

1. Python
2. TextTest - see TextTest for instructions for your platform
3. A lightweight editor like Sublime Text

You will want to configure TextTest to use the correct editor - see How to Configure Default Editor and Diff Tool

When you are developing, updating and fixing tests, you will want to do this interactively with the TextTest GUI. Start it like this:

cd integration_tests
.\start_texttest.bat

or on posix:

cd integration_tests
./start_texttest.sh

This should open the TextTest GUI. If you just want to run the tests non-interactively (eg on a build server) then you can pass the argument "-con" to just run the tests on the command line.

API tests with Specmatic

These tests will check the actual api against the OpenAPI specification in oas.yaml. Before you can run these tests you will need to download Specmatic. It comes in the form of a jar file so you will also need to install Java or a JRE in order to run it.

First start the application under test running:

npm start

Then run specmatic to check the api complies with the spec:

java -jar specmatic.jar test oas.yaml --testBaseURL=http://localhost:3001

OpenAPI validator code

In app.js you can find some validation code using OpenApiValidator that will check the API matches the spec. This code is currenly only checking the responses match the specs, not the requests. If you want to check the reqeusts too, set 'validateRequests' to true.

Exploratory testing

You can use the Swagger interface to explore the API. If you are a system administrator you will know the special Auth header that can be used for example to delete bookings:
