To run tests for the helixml/chat-widget project, follow the steps outlined below. The tests are integral to ensuring the functionality and reliability of the codebase.

Prerequisites

Ensure you have the following installed on your machine:

• Node.js (version 12.x or later)
• npm (Node Package Manager, which typically comes with Node.js)
• TypeScript (install globally if not already done)

You can check if these are installed by running the following commands:

node -v
npm -v
tsc -v

Step 1: Clone the Repository

First, clone the project repository to your local machine:

git clone https://github.com/helixml/chat-widget.git
cd chat-widget

Step 2: Install Dependencies

Once you are in the project directory, install the required dependencies using npm:

npm install

This command reads the package.json file and installs all the necessary packages mentioned in the dependencies and devDependencies sections.

Step 3: Configure TypeScript

If not already configured, ensure that your TypeScript settings align with the project’s requirements. The TypeScript configuration file (tsconfig.json) should be set up properly.

Here is an example of what a basic tsconfig.json might look like:

{
  "compilerOptions": {
    "target": "es5",
    "module": "commonjs",
    "strict": true,
    "esModuleInterop": true,
    "skipLibCheck": true,
    "forceConsistentCasingInFileNames": true,
    "outDir": "./dist"
  },
  "include": ["src/**/*"]
}

Step 4: Run Tests

Once everything is set up, you can execute the tests. The tests are commonly run using a testing framework, which should be installed as part of the project’s dependencies.

To run the tests, execute the following npm command:

npm test

This command will kick off the test suite defined in the project. The framework typically used in projects like this may utilize Jest or Mocha.

Example Test Command

If you are using Jest for testing, the script entry in package.json might look like this:

"scripts": {
  "test": "jest"
}

When the npm test command is executed, Jest will find and run all the test files that match the pattern defined in your configuration, usually files with .test.ts or .spec.ts extensions.

Step 5: Review Test Results

After the tests have completed running, you should review the results displayed in the terminal. Successful tests will typically show a summary, while failing tests will provide detailed output to help in diagnosing issues.

For instance, failing tests might output a message like:

FAIL src/__tests__/example.test.ts
  ● example test
    expect(received).toBe(expected) // Object.is equality

    Expected: true
    Received: false

Step 6: Debugging Failing Tests

If there are any failing tests, carefully review the messages and investigate the code related to the failures. Consider adding console logs or using a debugger to shed light on the state of the application when the tests fail.

Conclusion

Each of these steps is crucial for appropriately executing and troubleshooting tests within the helixml/chat-widget project. Consistent testing fosters code quality, aids in upstream development, and facilitates easier maintenance of the software over time.
