Proxy Example Wrong

Code snippets for the Twilio API documentation

Guidelines

Snippets should use environmental variables to store user account information instead of placeholders. For example (in NodeJS):
```
accountSid = process.env.TWILIO_ACCOUNT_SID
```
Instead of:
```
accountSid = "ACXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX"
```
As the latter impose a high security risk for users who push their own credentials on public repositories.
Critical user account information that should be stored on environmental variables is:
- Account SID
- Sub accounts SIDs
- Authentication Token
- API key SID
- API key Secret
Any other information such as Call SID, etc. can have placeholders on them:
```
Call SID:    CAXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
```
In the case of phone numbers, the following should be used:
```
Destination Phone Number: +15558675310
From/Twilio Number: +15017122661
```
Snippet file names are important. A snippet's file extension is the only way to mark them for a specific language. This is important because the language will be visible on the docs. Also, you must mark snippets with the twilio-client version that is used in that particular snippet.

For example, a java snippet that uses twilio-java v7.x should be named as: snippet-example-1.7.x.java

The same applies to the rest of languages and library versions, and this is the list of currently supported languages and versions:
```
snippet-example-1.6.x.java
snippet-example-1.7.x.java
snippet-example-1.2.x.js
snippet-example-1.5.x.js
snippet-example-1.7.x.rb
snippet-example-1.6.x.cs
snippet-example-1.4.x.php
snippet-example-1.8.x.php
snippet-example-1.9.x.py
```
And the full structure should look like this:
```
rest/
|-- resource-example/
    └── snippet-example-1/
        |-- output/
        |   └── snippet-example-1.json
        |-- snippet-example-1.7.x.java
        |-- snippet-example-1.<sdk-version>.x.<language>
        |-- snippet-example-1.json.curl
        |-- snippet-example-1.xml.curl
        └── meta.json
```
Client version is important, as that is how the test harness knows which version of the client it should use for testing.

Continuous Integration

All snippets are run in a container-based environment for each language (see .travis.yml file), so the first check we do is for syntax error.

There're two kind of snippets we test:

API/REST snippets: For these cases we only check syntax error. But, these snippets also do a request to Twilio's endpoints, so we mock this behaviour using a fake API server.

Note: The test doesn't check if the http request body is well formed to do what the intended snippet is supposed to do, e.g., if you have a snippet doing resource.update(propA=True), but the expected result is to update propB, the test may go green because there's no syntax error. That's because some attributes are optional to update, so the request body may or may not has the parameters needed to update the resource according to the expected result.
TwiML snippets: When running TwiML snippets, the snippets should print the xml result to the standard output, so we can capture that output and compare it with the expected xml sample. We read this /output/sample.xml file which is placed in the same folder of the snippet.

How to mark specific folders as testable

If you want a snippet folder to be tested, there are two ways to mark it as testable:

Using a meta.json file: This file is required and must live in all snippet folders, inside you can enable its specific folder for testing, adding "testable": true like so:
```
{
  "title": "Snippet title",
  "type": "server",
  "testable": true
}
```
Using a test.yml file: This file is optional and can live inside any folder, it's used to specify a deep recursive testing for all folders inside. So, if the marked directory contains several snippets, all of them will be marked as testable recursively. You just need to add testable: true to the file like so:
```
testable: true
```

Notes:

For testing TwiML snippets the option available is:
```
meta.json -> "test_output": true
test.yml -> test_output: true
```
This will compare the output of the snippet with the output/sample.xml file inside the same directory of the snippet.
You can mark a directory or a snippet to be not testable too.
```
meta.json -> "testable": false
test.yml -> testable: false
```
This way, you can mark snippets or directories to be tested or not, by exception.
For a snippet to be testable, it has to contain the basic things a program in that language should have. For example in Java, the code snippet should have a public class and a main method in it.
Specific dependencies are supported for snippets. If a new dependency is introduced, the testing scripts should be modified to support it.

Local Snippet Testing

The next steps describe how to run the snippets test locally in a UNIX based operating system (examples will be provided for Debian based Linux distributions and OSX using Homebrew). This has not been tested in a Windows OS.

Setting Up the Environment

Make sure you have the following dependencies installed on your system.

Install Node.js. The best option for this is to use nvm

curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.33.2/install.sh | bash \
export NVM_DIR="$HOME/.nvm" \
[ -s "$NVM_DIR/nvm.sh" ] && . "$NVM_DIR/nvm.sh" \
nvm install --lts
npm install

Install Python and PIP.

On Linux:

sudo apt-get install python-pip python2.7-dev build-essential \
sudo pip install --upgrade pip

On OSX:

brew install python

Once you have python and pip ready, run the command below

pip install -r requirements.txt

Install JDK8 and Gradle. The best option for this is to use sdkman

curl -s "https://get.sdkman.io" | bash \
source "$HOME/.sdkman/bin/sdkman-init.sh" \
sdk install java \
sdk install gradle

Install PHP 5 with CURL.

On Linux:

sudo add-apt-repository ppa:ondrej/php -y
sudo apt-get update
sudo apt-get install -y --force-yes php5.6

On OSX:

brew install php56

Once you have php ready, please install Composer

curl -sS https://getcomposer.org/installer | \
sudo php -- --install-dir=/usr/local/bin --filename=composer

Install Ruby and RubyGems.

curl -sSL https://get.rvm.io | bash -s stable --ruby

Install MonoDevelop.

On Linux (http://www.mono-project.com/docs/getting-started/install/linux/#usage):

sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys 3FA7E0328081BFF6A14DA29AA6A19B38D3D831EF \
echo "deb http://download.mono-project.com/repo/debian wheezy main" | sudo tee /etc/apt/sources.list.d/mono-xamarin.list \
sudo apt-get update \
sudo apt-get install mono-complete -y

On OSX:

brew install mono

Install Language Dependencies

The testing and installation scripts use ruby. Before installing language dependencies you need to install the following gems:

gem install json colorize nokogiri

You can use the following command to install language dependencies, which will download the latest version of the helper libraries for each language:

ruby tools/snippet-testing/model/dependency.rb

Note: That file specifies the latest version for every helper library for each language, but for java the files to specify the versions are located in: tools/snippet-testing/language_handler/file-templates/build.<version>.gradle where <version> should be 6 or 7.

Another option is to use the snippet_tester.rb file and pass the -i flag, this will try to install whatever dependency is needed before running the tests:

ruby tools/snippet-testing/snippet_tester.rb -i

Note: This will also install missing dependencies before running the tests. sudo will be used within the dependency installation script so you might need to enter your password. DO NOT run the whole script with sudo as it would install dependencies for the wrong user.

Run the Tests

Clone and run the fake-api server in a different terminal session.

git clone [email protected]:TwilioDevEd/twilio-api-faker.git \
cd twilio-api-faker \
sudo gradle run

Make your system trust the fake server's self signed certificate.
- On Linux:
```
sudo apt-get install ca-certificates \
sudo cp twilio-api-faker/keystore/twilio_fake.pem /usr/local/share/ca-certificates/twilio_fake.crt \
sudo update-ca-certificates
```
- On OSX: Use the system's keychain to trust the provided certificate in the keystore directory of the fake-api repo. Go here for more information.

Change your hosts file.

Edit your /etc/hosts file. Add the following entries:

127.0.0.1 api.twilio.com
127.0.0.1 chat.twilio.com
127.0.0.1 fax.twilio.com
127.0.0.1 ip-messaging.twilio.com
127.0.0.1 lookups.twilio.com
127.0.0.1 messaging.twilio.com
127.0.0.1 monitor.twilio.com
127.0.0.1 notifications.twilio.com
127.0.0.1 notify.twilio.com
127.0.0.1 pricing.twilio.com
127.0.0.1 preview.twilio.com
127.0.0.1 sync.twilio.com
127.0.0.1 taskrouter.twilio.com
127.0.0.1 video.twilio.com
127.0.0.1 wireless.twilio.com

Make a copy of the .env.example file.
```
cp .env.example .env
```
Set the necessary environment variables.

Change environment variables in the .env file to match your configuration and then use the source command to export the variables.
```
source .env
```
Finally, run the tests.
```
ruby tools/snippet-testing/snippet_tester.rb
```
Note: Remember to mark the directories you want to be tested with a test.yaml file. For more information go here.

You can also specify a directory to be tested (relative or absolute path). If a directory is specified, then the default testing behavior for that directory and everything it contains is true.
```
ruby tools/snippet-testing/snippet_tester.rb -d rest/making-calls
```

	say.sub('Words to be substituted', alias: 'alias')
	say.w('Words to speak')
	end

	puts response
