We are moving toward a future where everything is going to be autonomous, fast, and highly efficient. To match the pace of this fast-moving ecosystem, application delivery times will have to be accelerated, but not at the cost of quality. Achieving quality at speed is imperative and therefore quality assurance gets a lot of attention. To fulfill the demands for exceptional quality and faster time to market, automation testing will assume priority. It is becoming necessary for micro, small, and medium-sized enterprises (SMEs) to automate their testing processes. But the most crucial aspect is to choose the right test automation framework. So let’s understand what a test automation framework is.
The term “test automation framework” refers to a structure that provides a readymade test environment to execute the automated test codes. The framework comes with tools and features that can help its user execute the test scripts and develop and analyze the process.
It is a complete system on its own that serves the specific purpose of test automation. It consists of individual guidelines, standard code practices, ideas, procedures, project ranking, reporting frameworks, test data injections, etc. all of which work to support a successful test automation system. Thus, the framework provides its user with an existing template to set the automation process to execute it successfully.
Each test automation framework comes with its specific advantages like easy coding, extensibility, adaptability, ease of understanding, reduced cost and easy maintenance, etc. Hence, it is advisable to employ more than one framework to access multiple benefits from different frameworks relevant to your project.
We decided to test the following frameworks: Nightwatch.js, Cucumber and Cypress. Whereas Nightwatch.js and Cucumber uses the selenium webdriver, Cypress is selenium independent.
Nightwatch.js is an open-source, node.js powered, automated browser testing framework. It was developed in Amsterdam and derives its name from the famous painting ‘The Night Watch’ by Dutch 17th century artist Rembrandt van Rijn.
Nightwatch.js facilitates end-to-end testing of web applications and websites, by utilizing W3C Webdriver API (also known as Selenium Webdriver) as Selenium wrapper for interacting with different browsers. It helps in making the implementation of CI/CD much easier. At the same time, it can be used to perform Selenium test automation for both unit and integration tests. This popular automated browser testing framework provides several commands and assertions to perform interactions with web elements.
It is, at times referred to as a Selenium Binding library only, which is entirely true as it is mostly used together with Selenium Server. But while implementing, the tester must remember that Nightwatch.js in itself, is complete as it contains a built-in CLI test runner, an extendible command and assertion library, and support for page object model.

Cypress is a next generation front end testing tool built for the modern web.
Cypress enables you to write all types of tests:
Thus Cypress is used to test a wide range of applications that are operational in a browser. Cypress is free and we need not buy a license for its use. It allows us to create our test cases while our application is being developed. So it can be used best in a Test Driven Development framework. Cypress also has the Dashboard service which helps to record our test execution.
Cypress can be used for all sorts of development activities as it gives a platform where debugging is fast and code maintainability is easy.

Cucumber is an open-source testing framework that supports Behavior Driven Development for automation testing of web applications. The tests are first written in a simple scenario form that describes the expected behavior of the system from the user’s perspective.
Largely used for acceptance tests, Cucumber is written in Ruby, while the tests are written in Gherkin, a non-technical and human-readable language.
Behavior Driven Development gives us an opportunity to create test scripts from both the developer’s and the customer’s perspective as well. So in the beginning, developers, project managers, QAs, user acceptance testers and the product owner (stockholder), all get together and brainstorm about which test scenarios should be passed in order to call this software/application successful. This way they come up with a set of test scenarios. All these test scripts are in simple English language, so it serves the purpose of documentation also.
