Javascript Automated Testing Framework: Javascript Explained

Table of Contents

Javascript has become one of the most popular coding languages in the world, used by millions of developers for a myriad of different purposes. It’s known for its agility and ease of use, and it has become the go-to language for many web applications. But recently, more and more developers have turned to Javascript automation testing frameworks to help manage and streamline their development process.

What is Javascript?

Javascript is a lightweight programming language used to create powerful frontend interfaces for websites and web applications. It’s a scripting language, meaning that it can be embedded into HTML documents to quickly and easily add dynamic user interactions. It can be used to modify values in the page, handle events, do calculations, and more. It’s one of the most popular technologies employed in web development, and while its syntax has some similarities with Java, it’s still unique in its own right.

Javascript is a powerful tool for web developers, as it allows them to create interactive and engaging experiences for their users. It can be used to create dynamic menus, animations, and other interactive elements. It can also be used to create games, and even to create entire web applications. With its versatility and ease of use, Javascript is an essential tool for any web developer.

Benefits of Automated Testing

Automated testing is an invaluable tool for any developer, as it streamlines the testing process and allows them to quickly identify bugs and errors in their code. By using automated testing frameworks, developers can significantly reduce the amount of time they spend manually testing code. Instead, they can rely on automated tests to quickly find errors and identify potential issues in their code.

Aside from time-saving benefits, automated testing also offers added reliability. By having a consistent set of tests that can be re-run on any given codebase, developers can be confident that their code works as intended. This means bugs can be picked up much faster than with manual testing, and the possibility of them escaping the development process is greatly reduced.

In addition, automated testing can help developers to ensure that their code is compliant with industry standards and regulations. By running automated tests, developers can quickly identify any areas of their code that may not meet the required standards, and make the necessary changes to ensure compliance.

Overview of Javascript Automated Testing Framework

In order to get started with Javascript automated testing, you’ll need to select a framework that suits your needs. The most popular Javascript automation testing frameworks include Jasmine, QUnit, Selenium, and Protractor. Each of these frameworks provide different levels of support for test automation, so it’s important to review their features and decide which one works best for your project.

Once you’ve settled on a framework of choice, you’ll need to install it into your development environment. For example, packages such as Mocha and Chai are easy to set up simply by running an installation command from the command line. These packages can then be included in a project by requiring them in a project’s entry point script.

Setting Up a Javascript Automated Testing Environment

Once your chosen framework is ready to go, you’ll need to configure your testing environment. This involves setting up tools such as a transpiler or bundler that will allow you run your tests in the environment of your choice (Node.js, Browsers, React Native, etc.). You’ll also need to configure automated test runners such as Mocha or Jasmine.

Next, you’ll need to specify the type of tests that you want to run using your framework (unit testing, integration testing, etc.), and then create and write your tests within the defined framework. For example, with Jasmine, you can write tests as JavaScript objects within Jasmine’s describe/it construct.

Writing Tests with Javascript Frameworks

Once your test environment is up and running, you can begin writing your tests. This involves creating different JavaScript objects and functions within your test framework. The goal is to create test functions for each major area of functionality within your application. Each test should describe what the expected result should be for a specific input and validate that it is being achieved. It’s important to keep your tests as simple as possible in order to reduce complexity and readability.

Your tests should also encompass all error conditions so as not to leave any functionality untested. Additionally, if you’re using a static type checker such as TypeScript or Flow, it’s important to create tests for the type checker as well. This will help ensure that types are being enforced properly within the codebase.

Running Tests with Javascript Automation Tools

Once your tests have been written and configured, it’s time to run them using your chosen test automation tool. The most popular tools for running automated tests include Grunt, Karma, Protractor, and Selenium. All of these tools provide different features and levels of support when it comes to running automated tests, so it’s important to choose one that works best for your project.

Each tool provides different ways of running tests: some allow you to specify the scripts you want to run and will then run them automatically; others allow you to set up a custom configuration file that can be used to trigger particular scripts under certain conditions; while some provide a command-line interface where you can enter specific commands and parameters in order for your tests to run.

Best Practices for Javascript Automated Testing

When it comes to automating tests with JavaScript frameworks, there are certain best practices that should be followed in order to ensure the most efficient results. Most of these best practices involve structuring your tests in a logical way. This includes writing tests that describe clear expectations for inputs, creating consistently named functions and variables, writing maintainable code by utilizing abstraction layers, and keeping tests simple enough to be easily maintainable.

It’s also important to use code coverage tools such as Istanbul or Blanket in order to measure how much of your code is actually being tested by your automated tests. Finally, using existing coding standards such as ESLint or Stylelint can help keep your code clean and consistent across different environments.

Troubleshooting Common Issues

When it comes to automated testing with Javascript frameworks, common issues often arise due to incorrect use of the framework or due to inconsistencies in the code base. It’s important to pay attention to your test output and logs when running tests so that any potential issues can be identified quickly and dealt with accordingly.

If code coverage tools have been enabled, then these should also be consulted to ensure that all parts of the application are being adequately tested. Additionally, if there are any third-party libraries being used within the application, then these should also be included in the coverage reports.

Integrating Javascript Automated Testing Into Your Workflow

Finally, integrating automated testing into your workflow can help streamline the development process and improve overall quality assurance. Setting up an automated test suite within your development environment will ensure that all changes are tested before they are deployed, significantly reducing the likelihood of introducing bugs or errors into production. In addition, integrating automated tests into Continuous Integration/Continuous Delivery (CI/CD) pipelines can help ensure that no changes slip through the cracks.

In addition to streamlining development, adding automated testing can also boost overall developer productivity. By having clear expectations for codebase quality already established within an automated test suite, developers can more confidently make changes knowing that their work will be tested before it is deployed.
