# HealthcarePhony

This is an admittedly _rough_ RubyGem used to generate fake data that can be used in creating test HL7, CSV, or other data for healthcare integration testing. 

## Installation

Add this line to your application's Gemfile:

```ruby
gem 'healthcare_phony'
```

And then execute:

    $ bundle install

Or install it yourself as:

    $ gem install healthcare_phony

## Usage

The general purpose of this gem is to generate various pieces of data useful in creating test healthcare integration data.  Like HL7 messages or CSV files. The high level objects available are:

* Patient
* Patient Visit
* HL7 Message
* Doctor

### Patient

```ruby
patient = Patient.new
```

The above will give you a default Patient object:

```

The creation of the Patient can be customized by sending the following parameters when initializing:

* blank &rarr; An integer representing the % of times PatientName components should be blank.
* names_count &rarr; By default one PatientName is generated, this allows you to specify a number > 1.
* address_count &rarr; By default on Address is generated, this allows you to specify a number > 1.
* min_age &rarr; A minimum age (in years) for the Patient. 
* max_age &rarr; A maximum age (in years) for the Patient.
* race_count &rarr; By default on Race is generated, this allows you to specify a number > 1.

```

The above will give you a default Hl7Message object:

```
#<HealthcarePhony::Hl7Message:0x00007f81979beb58

## Examples

See the examples directory.

So far there phony_adt_sender.rb.  This script will generate a specified number of fake ADT messages and send them to the specified host and port using TCP/IP mllp.

Command line argument description:

```text
Usage: phony_adt_sender.rb [options]

    -n, --number NUMBER              Number of messages to send
    -h, --host HOST                  IP or DNS for listening host
    -p, --port PORT                  Listening port
    -c, --config CONFIGFILE          Path to configuration file (YAML) for message parameters
        --mllp-start HEX             Hex character(s) to denote start of message bytes. In form nn (example 0b for vertical tab) or nnnn (example 1c0d for file separator & carriage return)
        --mllp-end HEX               Hex character(s) to denote start of message bytes. In form nn (example 0b for vertical tab) or nnnn (example 1c0d for file separator & carriage return)
        --help                       Show this message
```

An example config file is also in the examples directory.

So to send 100 messages to 192.168.1.50:3022 using a config file phony_adt_sender.yml with non-standard mllp beginning/ending.

```text
ruby phony_adt_sender.rb -h 192.168.1.50 --number 100 --port 3022 --config phony_adt_sender.yml --mllp-start 05 --mllp-end 0304
```

Also in the examples directory are two files that can be used to generate a CSV.

* phony_csv.yml &rarr; a configuration file that can be used to set parametesr for generation patients.  Then two items specific to creating the CSV
  * number_of_rows &rarr; The # of rows to write
  * template_file &rarr; Path to a ERB template for the CSV.  If not specified the default in the library is used.
* bigger_csv_example.erb &rarr; Just another CSV template example.

Using these files in IRB (or in a script) you could do:

```ruby
csv_parameters = Psych.load_file('./examples/phony_csv.yml')
csv = HealthcarePhony::CsvFile.new(csv_parameters)
csv.to_file("d:/temp/testnewtemplate.csv")
```
