Author message:

This @cybernaut package is not developed any further. Please use the new @cybernaut/test package.

@cybernaut/engine

The heart of Cybernaut: An engine for reliably asserting/verifying conditions and for reliably performing actions.

Installation

npm install --save @cybernaut/engine

Compatible APIs

• @cybernaut/chrome

Usage example

const {Engine} = require('@cybernaut/engine/lib/Engine');

const {assert, perform, verify} = new Engine();

(async () => {
  await assert(anyCondition);

  await perform(anyAction);

  if (await verify(anyCondition)) {
    /* Do something ... */
  }
})().catch(error => {
  console.error(error);

  process.exit(1);
});

Note: This example uses language features of ECMAScript 2017. Particularly useful are async functions which are natively supported by Node.js 7.6.0 or later.
