By the end, you'll be equipped to implement and configure these tools for automated testing in your CI/CD pipeline.

Anatomy of a CI/CD Pipeline

In this module, we will explore the anatomy of a CI/CD pipeline, delving into its stages and how it facilitates the seamless integration of software delivery. You'll understand the differences in pipeline responsibilities for developers and testers, ensuring alignment in workflows. Additionally, you’ll gain hands-on experience by creating Jenkins jobs and GitHub Actions pipelines through their intuitive UIs, automating key tasks in the process.

Unit Testing in Jenkins

In this module, we will focus on integrating unit testing into Jenkins pipelines. You’ll learn how to set up Jenkinsfiles in your IDE to automate both backend and frontend unit tests. Additionally, you’ll explore how to publish and visualize test results and code coverage reports for both frontend and backend components. Finally, you’ll optimize testing performance by enabling parallel test executions to speed up the testing process in Jenkins.

API Testing in Jenkins

In this module, we will dive into API testing within Jenkins, starting with how to run API tests locally as part of your development process. You’ll also learn how to configure Jenkins to launch applications for testing, execute API tests in your CI/CD pipeline, and generate reports. By the end, you'll know how to publish and visualize API test results within Jenkins, ensuring smooth and efficient API testing workflows.

E2E Testing in Jenkins

In this module, we will guide you through executing end-to-end (E2E) tests, starting with running them locally to ensure smooth integration. You’ll then learn how to set up Jenkins to execute E2E tests within your CI/CD pipeline. Finally, you’ll discover how to publish and analyze the results of your E2E tests in Jenkins, ensuring the application works as expected across all components.

Performance Testing in Jenkins

In this module, we will cover performance testing within Jenkins, starting with running performance tests locally to identify potential bottlenecks. You’ll then learn how to integrate and execute performance tests within your Jenkins pipeline. Additionally, we’ll guide you through generating and publishing performance test results, and adjusting performance test thresholds to refine your build conditions in Jenkins, ensuring optimal application performance.

Unit Testing in GH Actions

In this module, we will focus on executing unit tests within GitHub Actions. You’ll learn how to configure and run both backend and frontend unit tests in your CI/CD pipeline. Additionally, we’ll guide you through generating and publishing test results and code coverage reports for both frontend and backend components. You’ll also discover how to create code coverage comments for better visibility and enhanced collaboration in GitHub Actions, making your testing process even more effective.

API Testing in GH Actions

In this module, we will guide you through the process of API testing within GitHub Actions. You’ll begin by learning how to run API tests locally, followed by setting up your application to run within the GitHub Actions pipeline for testing. We will also cover how to execute automated API tests and publish the results, ensuring clear and actionable reports within GitHub Actions for better insights and validation.
