Understanding Cypress.json

Cypress.json is a configuration file used by the Cypress testing tool. It plays a crucial role in setting up and customizing the Cypress environment for your tests. In this article, we will explore the definition, purpose, location, and provide a detailed walkthrough of Cypress.json examples.

Cypress JSON File: Definition and Purpose

The Cypress.json file is a JSON (JavaScript Object Notation) file that contains various options and settings for configuring Cypress. It allows you to customize the behavior of the Cypress test runner, specify environment variables, set up reporters, and more.

JSON, which stands for JavaScript Object Notation, is a lightweight data interchange format. It uses a simple syntax to represent data structures consisting of key-value pairs, arrays, and nested objects. Cypress.json utilizes this syntax to define the configuration options for Cypress.

By modifying the Cypress.json file, you can tailor Cypress to suit your specific testing needs. Whether you want to change the default test spec file, set environment variables, or configure reporters, Cypress.json provides a centralized location to manage these settings.

Where is Cypress.json Located?

Cypress.json is typically located at the root of your Cypress project. When you initialize a new Cypress project using the Cypress CLI, it automatically creates a Cypress.json file for you. If the file is missing, Cypress will use default values for its configuration options.

Here’s an example of a typical Cypress project structure:

├── cypress │ ├── fixtures │ ├── integration │ ├── plugins │ ├── support │ └── cypress.json └── package.json

As you can see, the Cypress.json file resides alongside other directories such as fixtures, integration, plugins, and support. This central location ensures easy access and management of the Cypress configuration.

Cypress.json Example: A Detailed Walkthrough

To better understand the structure and usage of Cypress.json, let’s walk through an example. Consider the following Cypress.json file:

json { "testFiles": "**/*.spec.js", "reporter": "cypress", "env": { "baseUrl": "https://www.example.com", "apiKey": "YOUR_API_KEY" } }

In this example, we have defined three key options within the Cypress.json file:

testFiles: This option specifies the pattern for matching test files. In this case, it is set to **/*.spec.js, which means all files ending with .spec.js will be considered as test files.
reporter: Here, we have set the reporter option to “cypress”. This determines the reporter plugin that Cypress will use to generate test reports.
env: The env option allows you to define environment variables that can be accessed within your tests. In this example, we have set the baseUrl and apiKey variables.

By leveraging the power of Cypress.json, you can easily customize these options and many more to suit your specific testing requirements.

Remember, Cypress.json is just one part of the Cypress configuration. You can also use other configuration files like plugins/index.js and support/index.js to further extend the capabilities of Cypress.

That’s it! You now have a better understanding of Cypress.json, its purpose, location, and how to configure it using JSON syntax. Feel free to explore more examples and experiment with different options to enhance your Cypress automation testing.

Default JSON Options

The default JSON options in Cypress.json provide a way to set global configurations for your tests. These options include the default test spec file, the reporter to use for test results, and the environment variables to pass to your tests. By specifying these options in the Cypress.json file, you can ensure that they are applied to all your tests unless overridden.

Here are some examples of default options in Cypress.json:

json { "default": { "testFiles": "**/*.spec.js", "reporter": "cypress", "env": { "baseUrl": "https://example.com", "apiKey": "123456789" } } }

In the above example, the default test files are set to match any file with the “.spec.js” extension. The “cypress” reporter is used to generate test reports, and the environment variables “baseUrl” and “apiKey” are passed to the tests.

Global Options

Global options in Cypress.json allow you to configure settings that apply to all tests within your Cypress project. These options include the default timeout for Cypress commands, the behavior of screenshots and videos, and the viewport size and actionability.

To set global options, you can use the following syntax in Cypress.json:

json { "baseUrl": "https://example.com", "defaultCommandTimeout": 5000, "screenshotsFolder": "cypress/screenshots", "videosFolder": "cypress/videos", "viewportWidth": 1280, "viewportHeight": 720, "waitForAnimations": true }

In the above example, the “baseUrl” is set to “https://example.com” for all tests. The default command timeout is set to 5000 milliseconds, and screenshots and videos are stored in the specified folders. The viewport size is set to 1280×720 pixels, and animations are waited for before performing actions.

Cypress JSON Timeout

The Cypress JSON timeout option allows you to specify the timeout duration for Cypress commands. This timeout determines how long Cypress will wait for a command to complete before considering it as a failure. By default, the timeout is set to 4000 milliseconds.

To modify the timeout duration, you can add the following option to Cypress.json:

json { "defaultCommandTimeout": 6000 }

In the above example, the timeout for Cypress commands is increased to 6000 milliseconds.

Screenshots and Video Options

Cypress provides options for capturing screenshots and videos during test execution. These options allow you to control the behavior of screenshots and videos, such as their storage location and whether to include them in test reports.

To configure screenshots and videos, you can use the following options in Cypress.json:

json { "screenshotsFolder": "cypress/screenshots", "videosFolder": "cypress/videos", "includeScreenshotsInReport": true, "includeVideoInReport": true }

In the above example, screenshots are stored in the “cypress/screenshots” folder, and videos are stored in the “cypress/videos” folder. The screenshots and videos are also included in the test reports.

Viewport and Actionability

The viewport and actionability options in Cypress.json allow you to define the default viewport size and control the behavior of Cypress commands related to actionability.

To set the viewport size and actionability options, you can use the following syntax in Cypress.json:

json { "viewportWidth": 1280, "viewportHeight": 720, "waitForAnimations": true }

In the above example, the default viewport size is set to 1280×720 pixels. The “waitForAnimations” option is set to true, which means Cypress will wait for animations to complete before performing actions.

By configuring Cypress.json, you can customize the behavior of Cypress and tailor it to your specific testing requirements. Whether it’s setting default options, specifying timeouts, managing screenshots and videos, or controlling the viewport and actionability, Cypress.json provides a flexible way to configure your Cypress automation.

Overriding Default Values

Overriding Default Values in the Cypress.json File

In Cypress, the default configuration values are defined in the Cypress.json file. However, there may be situations where you need to override these default values to suit your specific needs. This can be done by modifying the Cypress.json file or by using the Cypress API within your test script.

Modifying the Cypress.json File

The Cypress.json file is the central configuration file for your Cypress setup. It contains various options and settings that control the behavior of the Cypress testing tool. By modifying this file, you can customize the default values according to your requirements.

To override a default value in the Cypress.json file, you simply need to locate the corresponding option and set it to the desired value. For example, if you want to change the default reporter used for test results, you can modify the "reporter" option in the Cypress.json file.

Here is an example of how you can override the default reporter:

json { "reporter": "cypress", "env": { "reporter": true } }

In this example, the "reporter" option is set to "cypress", which means that the Cypress test runner will use the Cypress reporter for displaying test results. Additionally, the "env" object is used to pass the "reporter" option with a value of true, enabling the reporter.

Using Cypress API in the Test Script

Another way to override default values is by using the Cypress API within your test script. This gives you more flexibility as you can dynamically set values based on specific conditions or requirements.

To override a default value via the test script, you can use Cypress commands and methods to modify the configuration options. For example, you can use the Cypress.env() method to access and modify environment variables during runtime.

Here is an example of how you can override a default value in the test script:

“`javascript
// Set a default value for a specific test
Cypress.env(“reporter”, “json”);

// Access the overridden value
const reporter = Cypress.env(“reporter”);
“`

In this example, the Cypress.env() method is used to set the "reporter" option to "json". This means that the test will use the JSON reporter for displaying test results. The overridden value can then be accessed using the same method.

By leveraging the flexibility of the Cypress API, you can override default values in a more dynamic and granular manner, allowing for greater customization and control over your Cypress automation.

Overriding Default Values via the Test Script

In addition to modifying the Cypress.json file, you can also override default values directly within your test script. This approach is useful when you need to set specific values for a particular test or scenario.

To override a default value via the test script, you can use Cypress commands and methods to modify the configuration options. For example, you can use the Cypress.config() method to set options such as the default test spec or the default reporter.

Here is an example of how you can override default values via the test script:

“`javascript
// Set a default test spec
Cypress.config(“defaultTestFiles“, [“path/to/custom/spec.js”]);

// Set a default reporter
Cypress.config(“reporter“, “json”);

// Access the overridden values
const defaultTestFiles = Cypress.config(“defaultTestFiles”);
const reporter = Cypress.config(“reporter”);
“`

In this example, the Cypress.config() method is used to set the "defaultTestFiles" option to a custom test spec file and the "reporter" option to "json". These overridden values will be used for the specific test or scenario.

By overriding default values via the test script, you have more control over the configuration options on a per-test basis, allowing for greater flexibility and customization in your Cypress project.

Remember, whether you choose to modify the Cypress.json file or override default values via the test script, understanding the JSON syntax and the available options is crucial for effective customization of your Cypress setup.

Here’s an example of how you can read a JSON file in Cypress:

javascript cy.readFile('cypress.json').then((json) => { // Access the JSON data and perform assertions or actions cy.log(json); });

Cypress Fixture JSON Array

Fixtures in Cypress are a way to load external data into your tests. If you have a JSON array that you want to use as test data, you can store it in a fixture file and load it into your tests using the cy.fixture() command. This allows you to easily manage and reuse test data across multiple tests.

Here’s an example of how you can load a JSON array from a fixture file in Cypress:

javascript cy.fixture('data.json').then((data) => { // Access the JSON array and perform assertions or actions cy.log(data); });

Cypress JSON Object

In addition to reading JSON files and using JSON arrays, Cypress also allows you to work with JSON objects directly within your tests. JSON objects are useful for storing and manipulating structured data. You can create JSON objects in Cypress using JavaScript objects and use them in your tests.

Here’s an example of how you can work with a JSON object in Cypress:

“`javascript
const user = {
name: ‘John Doe‘,
email: ‘johndoe@example.com’,
age: 25,
};

cy.wrap(user).should(‘have.property’, ‘name’, ‘John Doe‘);
“`

By utilizing these advanced configurations, you can leverage the power of JSON files, fixtures, and objects in your Cypress tests. This allows for more flexibility in managing test data, configuration settings, and structured data within your tests.
