Taiko – A Free and Open Source Browser Automation Tool

Taiko is an automation tool that is freely available and it is an open-source browser automation tool. It is built by the ThoughtWorks team. It uses the Node.js library to automate the chrome browser. Taiko is very useful to create maintainable and highly readable JavaScript tests. 

Taiko has a simple API, smart selectors, and implicit waits. All these work together towards a single goal – No more flaky tests.

Taiko Features

Taiko is built ground up to test modern web applications. Below is a list of some of Taiko’s features that differ from other browser automation tools.

  1. Easy Installation
  2. Interactive Recorder
  3. Smart Selectors
  4. Handle XHR and dynamic content
  5. Request/Response stubbing and mocking

Easy Installation

We can use Taiko on three platforms:

1. Windows
2. macOS
3. Linux

Before starting work on Taiko scripts in JavaScript, Node.js should be installed in your system. After that open a command prompt (For Windows) and install Taiko using the below command:

$ npm install -g taiko

This will install Taiko and the Chromium browser with the latest version.

Taiko tool comes with a REPL Recorder which uses for writing test scripts. To launch the REPL, just type in CMD : 

$ taiko

Here is the output:

Version: 0.8.0 (Chromium:76.0.3803.0)

Type .api for help and .exit to quit

This will open the Taiko prompt in your cmd application. Now you can use Taiko’s API.

Let’s perform some tasks: 

Taiko’s REPL keeps a history of all run commands. Once execution finishes, you can generate a test script using the below command : 

> .code

You can copy and modify the javascript code or save it to a file in your system using the below command:

> .code taiko_demo.js

As you can see the file save in the system.

file is saved in the system

You can finish the recording using the command shown below :

> .exit

If you want to run a Taiko script, for that you need to pass the file as an argument to Taiko

Run a Taiko script

By default Taiko runs the script in headless mode, this makes it easy to run Taiko.
To view the browser while executing the script, run the command : 

$ taiko googlesearch.js –observe

There are some other methods of taiko that we can use to perform other tasks of taiko. To check all available APIs, run the command :> .api

For more details of an API with examples use:

>.api openBrowser



    openBrowser({ headless: false })



  • What are the taiko automation tool limitations?

Taiko does not assist with mobile app testing. There are no plans to support this. Taiko will only support programming languages that compile JavaScript, unlike Selenium, which may be programmed in a variety of computer languages.

  • What is Taiko testing?

Taiko was created specifically to test contemporary web applications. It generates taiko Code examples of JavaScript tests that are easy to read and maintain. Implicit waits, clever selectors, and a straightforward API all contribute to a single objective. No more erratic testing

  • How to do Test Automation Using Taiko and Gauge?

We advise combining Test Automation Using Taiko and Gauge. Gauge is a test runner for writing markdown-formatted acceptance tests that are readable and reusable. It integrates well with Taiko and is simple to install. You can now begin writing test specifications using Gauge after creating your project with Taiko and Gauge.
