Tellerium

This module provides facilities for execution of captured browser tests.

The only file format currently supported is output from Selenium IDE. Files in this format can be loaded directly, validated and executed.

Tests can be exdecuted by the following engines:

Chromium (via Puppeteer)
Selenium Webdriver
Browsertack (using Selenium)

tests are executed headless in puppeteer by default

Use

CLI

A simple command line binary is provided that allows going straight from loading a file to having the tests executed and their success or failure displayed in the style of a stanard JavaScript terminal test runner.

tellerium execute --type side /path/to/file.side

npx

The module can be used without installation as a tool by using it with npx:

npx tellerium execute --type side /path/to/file.side

Library

Tellerium can also be integrated as a library. The simplest way of doing this is to use a helper function to directly load a test file.

Integrating this into an existing test suite is as simple as:

const sidedriver = tellerium.fromFile(
  path.join(TEST_DATA, "example.side"),
  "side"
);

describe("when running some browser tests", function() {
  this.before(() => {
    return sidedriver.createEnvironment();
  });

  after(() => {
    return sidedriver.destroyEnvironment();
  });

  it("should work", () => {
    return sidedriver.runTest("example");
  });
});

The exported fromFile() function takes care of loading tests from the supplied file and returns an instance of the main class.

This class can also be constructed via the named export Tellerium which allows passing test cases directly:

const instance = new tellerium.Tellerium({
  testCases: [
    {
      name: "sometest",
      commands: [
        /*...*/
      ]
    }
  ]
});

Options

Test execution can be customised by provided additonal options. While the module defaults to headless puppeteer, seeing the output visually can be requested by supplying the --ramble option. Execution of the tests via a selenium webdriver is also supported via --selenium.

BrowerStack

The module also has preliminary support for testing in BrowserStack. This can be configuried by using the --browserstack option and then invoking the binary with the following two environment variables:

BROWSERSTACK_USERNAME - the user to connect with
BROWSERSTACK_KEY - the API key for this user

An example invocation of this is as follows:

BROWSERSTACK_USERNAME=user BROWSERSTACK_KEY=xxx ./bin/tellerium --browserstack --type side ./example.side

Currently the module will select Chrome running on an arbitrary platform but upcoming changes are likely to expand the configuration syntax.

Support

Selenium IDE

Four basic commands are currently impelemented:

open
click
type
waitForElementVisible
