Flamegraph-renderer-example

Testing

There are a couple ways of testing the FlamegraphRenderer component:

1. mocking the entire component

See ./src/App.mock.spec.jsx

2. Supporting canvas

In this method you actually render the entire tree.

For that you need to:

Install canvas
Install jest-canvas-mock
Add jest-canvas-mock to your jest setup (./src/setupTests.js)
Update your jest config to not reset mocks (./jest.config.ts)

An example test is available at ./src/App.spec.jsx

Running

yarn
yarn start
