Navigate to the Project Directory: Make sure you're in the root directory of the TigerBeetle project, which you cloned in the previous step.
Build for WASM: Use Cargo to build the project targeting WASM. Run the following command in your terminal:
```
cargo build --target wasm32-unknown-unknown --release
```
This command instructs Cargo to build the project in release mode for the WASM target. The --release flag optimizes the build for performance.
Locate the Output: After the build process completes successfully, the WASM file will be located in the target/wasm32-unknown-unknown/release/ directory. The file will typically be named tigerbeetle.wasm.

That's it! You've successfully built the WASM version of TigerBeetle. Now you're ready to test it. It might take a while to complete the build, depending on your machine’s resources, but be patient, it will be worth it. Make sure you don’t run into any errors during the build process. If you do, double-check your environment setup, and ensure that you have all the necessary tools installed and configured correctly.

Testing xpApi Features: The Fun Part

Now for the most exciting part: testing the xpApi features of your newly built WASM version of TigerBeetle. Testing is crucial to ensure that the WASM build functions as expected and that you can seamlessly integrate it into your projects. There are several ways to approach this, from simple unit tests to more comprehensive integration tests. Here’s a streamlined approach to testing:

Choose a Testing Framework: You can use any WASM-compatible testing framework. If you're building within a browser, you might use frameworks like Jest or Mocha. If you're testing from a Node.js environment, you could use the built-in assert module or a testing framework like Mocha or Chai. The choice depends on your specific needs and the environment you're testing in.
Write Test Cases: Create test cases that cover various xpApi functionalities. These test cases should be designed to validate different aspects of the API, such as account creation, transfer of funds, querying account balances, and more. Make sure to test both positive and negative scenarios.
Load the WASM File: Load your tigerbeetle.wasm file into your testing environment. You can do this using the fetch API, or by using a module bundler such as Webpack or Parcel.
Instantiate the WASM Module: Instantiate the WASM module. This process involves creating an instance of the compiled WASM code in your chosen testing environment. This allows you to interact with the TigerBeetle code through JavaScript or other languages.
Call xpApi Functions: Call the xpApi functions through the instantiated module. You'll need to define the function signatures in your test code to call the respective functions.
Verify Results: Verify the results of your API calls. This involves checking the return values and the state of the data to ensure that everything works as expected.

By following these steps, you can create a robust testing suite for your WASM build of TigerBeetle, and have confidence in the xpApi functionality. The most important thing is to be thorough in your testing and cover all the key features to make sure everything works seamlessly.

Example Test Case: Creating an Account

To make things clearer, let’s look at a simple example test case that covers creating an account using the xpApi:

// Assuming you have loaded the wasm file and instantiated the module
const wasm = await import('./tigerbeetle.wasm');

// Define a test function
async function testCreateAccount() {
  try {
    // Define an account object
    const account = {
      id: 12345n, // BigInt for 64-bit integer
      code: 0,   // Customize these values as needed
      ledger: 0, // Customize these values as needed
      flags: 0,  // Customize these values as needed
    };

    // Call the createAccount function from the WASM module
    const result = wasm.createAccount(account.id, account.code, account.ledger, account.flags);

    // Assert that the account was created successfully
    if (result === 0) {
      console.log('Account created successfully');
    } else {
      console.error('Account creation failed', result);
    }

  } catch (error) {
    console.error('Error creating account', error);
  }
}

// Run the test
testCreateAccount();

This simple example showcases how you can call the createAccount function from your WASM module and check whether the account was created successfully. You can extend this test case to cover various scenarios, such as error handling, incorrect inputs, and more complex operations.
