Avo and tests

It can be useful to have your Avo Codegen running as a part of your test suite.

To that end, Avo generated tracking libraries can be initialized with a noop flag that disables network requests and only run data validation.

Below is an example of initializing Avo in a jest test environment with JavaScript:

describe('Avo', () => {
  var Avo;
  beforeAll(() => {
    Avo = require('./Avo');
    Avo.initAvo({ env: 'dev', noop: true, strict: true });
  });
  test('signupStart() with email property is valid', () => {
    Avo.signupCompleted({ email: 'test@test.com' });
  });
  test('signupStart() without email property throws', () => {
    expect(() => {
      Avo.signupCompleted();
    }).toThrow();
  });
});

The noop flag is supported in JavaScript, TypeScript, Reason, Java, Objective-C, Swift and Python.

Unit tests in Kotlin and Swift

In the generated Avo file we provide wrapping interface/protocol with all the event methods.

public interface Avo {
    fun feedbackGiven(
        path: String,
        feedback: String
    )
}

public protocol AvoProtocol {
    func feedbackGiven(
        path: String,
        feedback: String
    )
}

We suggest to mock it in your tests and verify that desired method is called with particular parameters.

Avo is the analytics governance platform for product data that lets you define it consistently, implement it correctly and trust it everywhere. Using an AI agent? Connect it to the Avo MCP at https://mcp.avo.app/mcp and it can read and change your tracking plan on a branch.
