Integrating Jest with JUnit and BrowserStack Observability through CI/CD

As the modern application development landscape continues to evolve, observability and automated testing have become essential pillars for any robust software development life cycle. BrowserStack Observability emerges as a next-generation tool, specifically designed for automation result tracking and deep-dive observability insights. developers can take advantage of converting Jest test results to the widely-supported JUnit format. This blog post aims to walk you through this process.

Objectives

1. Convert Jest test results to JUnit XML format, facilitating compatibility with BrowserStack Observability.

2. Implement this conversion within a CI/CD pipeline to automate the upload of JUnit test reports to BrowserStack Observability.

Pre-Requisites

• An established JavaScript project using Jest as the testing framework.

• Yarn as the chosen package manager.

• A CI/CD platform (this post will use GitHub Actions as an example).

• An active account with BrowserStack for accessing their Observability features.

• 
  

Step 1: Converting Jest Test Results to JUnit Format

Installing jest-junit

To get started, add jest-junit as a development dependency in your project's directory:

 yarn add jest-junit --dev

Update Jest Configuration

Open your jest.config.js file and append the following lines to your existing configuration:

 reporters: [
    "default",
    "jest-junit"]

Update JUnit configuration

Open your package.json file and append the following lines to your existing configuration:

 "jest-junit": {
  "suiteName": "your-suite-name",
  "outputDirectory": "./reports",
  "outputName": "junit.xml",
  "uniqueOutputName": "false",
  "classNameTemplate": "{classname}-{title}",
  "titleTemplate": "{classname}-{title}",
  "ancestorSeparator": " › ",
  "usePathForSuiteName": "true"
}

Step 2: Automated Upload to BrowserStack Observability

CI/CD Configuration Using GitHub Actions

Create a GitHub Actions workflow by placing a main.yml file under .github/workflows/

append the following lines to your existing configuration

make sure to update repository secrets with BROWSERSTACK_USERNAME and BROWSERSTACK_ACCESS_KEY

BrowserStack Observability is a groundbreaking tool in the arena of automated result tracking and observability. While awaiting the native support for Jest, the conversion to JUnit serves as an effective interim solution. By automating this process through your CI/CD pipeline, you can fully unlock the powerful features of BrowserStack Observability.
