Genesys Web Messaging Tester

Automatically test your Web Messenger Deployments

Allows behaviour for Genesys Chatbots and Architect flows behind Genesys' Web Messenger Deployments to be automatically tested using:

Scripted Dialogue - I say "X" and expect "Y" in response (example)
Generative AI - Converse with my chatbot and fail the test if it doesn't do "X" (examples)

Why? Well it makes testing:

Fast - spot problems with your chatbots sooner than manually testing
Repeatable - scenarios in scripted dialogues are run exactly as defined. Any response that deviates is flagged
Customer focused - expected behaviour can be defined as scenarios before development commences
Automatic - being a CLI tool means it can be integrated into your CI/CD pipeline, or run on a scheduled basis e.g. to monitor production

The above test is using the test-script:

examples/cli-scripted-tests/example-pass.yml

config:
  deploymentId: xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
  region: xxxx.pure.cloud
scenarios:
  "Accept Survey":
    - say: hi
    - waitForReplyContaining: Can we ask you some questions about your experience today?
    - say: 'Yes'
    - waitForReplyMatching: Thank you! Now for the next question[\.]+
  "Decline Survey":
    - say: hi
    - waitForReplyContaining: Can we ask you some questions about your experience today?
    - say: 'No'
    - waitForReplyContaining: Maybe next time. Goodbye
  "Provide Incorrect Answer to Survey Question":
    - say: hi
    - waitForReplyContaining: Can we ask you some questions about your experience today?
    - say: Example
    - waitForReplyContaining: Sorry. Please input "Yes" or "No". Do you want to proceed?

How it works

The tool uses Web Messenger's guest API to simulate a customer talking to a Web Messenger Deployment. Once the tool starts an interaction it follows instructions defined in a file called a 'test-script', which tells it what to say and what it should expect in response. If the response deviates from the test-script then the tool flags the test as a failure, otherwise the test passes.

Quick Start

Prepare your system by installing node

Install the CLI tool using npm:

npm install -g @ovotech/genesys-web-messaging-tester-cli

Testing with scripted dialogues

Write a dialogue script containing all the scenarios you wish to run along with the ID and region of your Web Messenger Deployment.

examples/cli-scripted-tests/example-pass.yml

config:
  deploymentId: xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
  region: xxxx.pure.cloud
scenarios:
  "Accept Survey":
    - say: hi
    - waitForReplyContaining: Can we ask you some questions about your experience today?
    - say: 'Yes'
    - waitForReplyMatching: Thank you! Now for the next question[\.]+
  "Decline Survey":
    - say: hi
    - waitForReplyContaining: Can we ask you some questions about your experience today?
    - say: 'No'
    - waitForReplyContaining: Maybe next time. Goodbye
  "Provide Incorrect Answer to Survey Question":
    - say: hi
    - waitForReplyContaining: Can we ask you some questions about your experience today?
    - say: Example
    - waitForReplyContaining: Sorry. Please input "Yes" or "No". Do you want to proceed?

Then run the test by pointing to the dialogue script file in the terminal:

web-messaging-tester scripted tests/example.yml

Testing with AI

This tool supports two GenAI providers:

ChatGPT (gpt-3.5-turbo model by default)
Google Vertex AI (PaLM 2 Chat Bison model)

Using ChatGPT

Start by setting up an API key for ChatGPT:

Create an API key for OpenAI
Set the key in the environment variable: OPENAI_API_KEY

Write a scenario file containing all the scenarios you wish to run along with the ID and region of your Web Messenger Deployment.

The scenarios are written as prompts, these can take some fine-tuning to get right (see examples here). The terminatingPhrases section defines the phrases you instruct ChatGPT to say to pass or fail a test.

examples/cli-ai-tests/chatgpt-example.yml

config:
  deploymentId: xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
  region: xxxx.pure.cloud
  ai:
    provider: chatgpt
    config:
      temperature: 1
scenarios:
  "Accept survey":
    setup:
      placeholders:
        NAME:
          - John
          - Jane
      prompt: |
        I want you to play the role of a customer called {NAME}, talking to a company's online chatbot. You must not
        break from this role, and all of your responses must be based on how a customer would realistically talk to a company's chatbot.

        To help you play the role of a customer consider the following points when writing a response:
        * Respond to questions with as few words as possible
        * Answer with the exact word when given options e.g. if asked to answer with either 'yes' or 'no' answer with either 'yes' or 'no' without punctuation, such as full stops

        As a customer you would like to leave feedback of a recent purchase of a light bulb you made where a customer service
        rep was very helpful in finding the bulb with the correct fitting.

        If at any point in the company's chatbot repeats itself then say the word 'FAIL'.

        If you have understood your role and the purpose of your conversation with the company's chatbot then say the word 'Hello'
        and nothing else.
      terminatingPhrases:
        pass: ["PASS"]
        fail: ["FAIL"]

Then run the AI test by pointing to the scenario file in the terminal:

web-messaging-tester ai tests/example.yml

For a slightly more detailed guide see: Let's test a Genesys chatbot with AI.

Using Google Vertex AI

Create a Google Cloud Platform (GCP) account and enabled AI access to Vertex AI
Authenticate the machine running this testing tool, with GCP
- The easiest way is setting up Application Default Credentials
Define a prompt to provide the model with context on how to behave during testing
- Learn more in Google's Introduction to prompt design

The terminatingPhrases section defines the phrases you instruct PaLM 2 to say to pass or fail a test.

    config:
      location: example-location
      project: example-gcp-project
      modelVersion: "002"
      examples:
        - input: "What would you like to do today?"
          output: "I would like to leave feedback, please"
