 - Tests should be *hermetic*. Tests should not depend on external services.
 - Tests should work on all three platforms: Mac, Linux and Win. This is especially important for screenshot tests.
 
-Puppeteer tests are located in [`test/test.js`](https://github.com/puppeteer/puppeteer/blob/master/test/test.js)
-and are written with a [TestRunner](https://github.com/puppeteer/puppeteer/tree/master/utils/testrunner) framework.

-# TestRunner
-
-This test runner is used internally by Puppeteer to test Puppeteer itself.
-
-- testrunner is a *library*: tests are `node.js` scripts
-- parallel wrt IO operations
-- supports async/await
-- modular
-- well-isolated state per execution thread
-- uses the `expect` library from `npm` for assertions.
-
-### Installation
-
-```sh
-npm install --save-dev @pptr/testrunner
-```
-
-### Example
-
-Save the following as `test.js` and run using `node`:
-
-```sh
-node test.js
-```
-
-```js
-const {TestRunner, Reporter} = require('@pptr/testrunner');
-const expect = require('expect')
-
-// Runner holds and runs all the tests
-const runner = new TestRunner({
-  parallel: 2, // run 2 parallel threads
-  timeout: 1000, // setup timeout of 1 second per test
-});
-
-// Extract jasmine-like DSL into the global namespace
-const {describe, xdescribe, fdescribe} = runner;
-const {it, fit, xit} = runner;
-const {beforeAll, beforeEach, afterAll, afterEach} = runner;
-
-// Test hooks can be async.
-beforeAll(async state => {
-  state.parallelIndex; // either 0 or 1 in this example, depending on the executing thread
-  state.foo = 'bar'; // set state for every test
-});
-
-describe('math', () => {
-  it('to be sane', async (state, test) => {
-    state.parallelIndex; // Very first test will always be ran by the 0's thread
-    state.foo; // this will be 'bar'
-    expect(2 + 2).toBe(4);
-  });
-});
-
-// Reporter subscribes to TestRunner events and displays information in terminal
-const reporter = new Reporter(runner);
-
-// Run all tests.
-runner.run();
-```
