Cloud Source Repository

Cloud Source Repositories has not been available to new customers since June 17, 2024. Organizations that used it before that date keep access, so the details below apply to existing users.

You can design, develop, and securely manage your code with Cloud Source Repository. You can collaborate smoothly on a fully featured, scalable, and private Git repository. You also have options to extend your Git workflow by connecting to other Google Cloud tools.

• Cloud Source Repositories are fully-featured, private Git repositories hosted on Google Cloud.
• Cloud Source Repositories can be used for collaborative, version-controlled development of any app or service, including those that run on App Engine and Compute Engine.
• Cloud Source Repositories can connect to an existing GitHub or Bitbucket repository. Connected repositories are synchronized with Cloud Source Repositories automatically.
• Cloud Source Repositories automatically send logs on repository activity to Cloud Logging to help track and troubleshoot data access.
• Cloud Source Repositories offer security key detection to block git push transactions that contain sensitive information, which helps improve the security of the source code.
• They provide built-in integrations with other GCP tools like Cloud Build, Cloud Operations, Cloud Logging, Cloud Functions, and others that let you automatically build, test, deploy, and debug code within minutes.

Cloud Build

Cloud Build is a service that executes your build on Google Cloud Platform’s infrastructure. Cloud Build can import source code from a variety of repositories or cloud storage spaces, execute build according to your specified specifications, and produce artifacts such as Docker containers or Java archives.

• A fully managed, server-less service that executes builds on Google Cloud Platform’s infrastructure.
• Can pull/import source code from a variety of repositories or cloud storage spaces, execute a build to produce containers or artifacts, and push them to the artifact registry.
• Executes the build as a series of build steps, where each build step specifies an action to be performed and is run in a Docker container.
• Build steps can be provided by Cloud Build and the Cloud Build community or can be custom as well.
• Build config file contains instructions for Cloud Build to perform tasks based on your specifications, e.g. the build config file can contain instructions to build, package, and push Docker images.
• Builds can be started either manually or using build triggers.
• Uses build triggers to enable CI/CD automation.

Container Registry

Google shut down Container Registry on March 18, 2025, and writing images to it is no longer possible. New pipelines store images in Artifact Registry, covered in the next section.

We often use the short name GCR for Google Container Registry. Google Container Registry, or GCR, is a service provider on the Google cloud platform that lets us store the Docker images and share them with the team. Now let’s look at some of the features of the GCR:

• Container Registry is a private container image registry that supports Docker Image Manifest V2 and OCI image formats.
• Container Registry provides a subset of Artifact Registry features.
• It stores its tags and layer files for container images in a Cloud Storage bucket in the same project as the registry.
• Access to the bucket is configured using Cloud Storage’s identity and access management (IAM) settings.
• Integrates seamlessly with Google Cloud services.
• Works with popular continuous integration and continuous delivery systems, including Cloud Build and best CI/CD tools such as Jenkins. If you want to create your first Jenkins pipeline, please refer to the Jenkins Pipeline Tutorial and get started.

Artifact Registry

Artifact Registry is a single place for your organization to manage container images and language packages (such as Maven and npm). It is fully integrated with Google Cloud’s tooling and runtimes and comes with support for naive artifact protocols.

• Artifact Registry is a fully-managed service with support for both container images and non-container artifacts, Artifact Registry extends the capabilities of Container Registry.
• Artifact Registry is the recommended service for container image storage and management on Google Cloud.
• Artifact Registry comes with fine-grained access control via Cloud IAM. This enables scoping permissions as granularly as possible, for example, to specific regions or environments as necessary.
• Artifact Registry supports the creation of regional repositories.

Cloud Deploy

Google Cloud Deploy is a managed service that automates the delivery of your applications to a series of target environments in a defined promotion sequence. Google Cloud Deploy uses Scaffold to separate rendering tools from the delivery pipeline.

It makes manifest rendering more flexible without affecting how you define your delivery pipeline.

How to build Continuous Quality with Google Cloud CI CD Pipeline?

Using TestMu AI, you can perform both manual and automated cross browser testing at scale over an online device farm of 3000+ real devices and operating systems. Test automation platform like TestMu AI allow you to harness the power of cloud-based online Selenium Grids in conjunction with our local grid setups.

While the local Selenium Grid is a good start, it is difficult to scale the test efforts exponentially. This is where cloud Selenium Grid can be helpful in reaping the benefits offered by Cloud and Selenium. A cloud Selenium Grid like TestMu AI lets you scale your automation efforts by performing Selenium automation testing at scale on a secure, reliable, and scalable grid on the cloud.

Here’s a quick glimpse of performing Selenium automation testing on the TestMu AI platform.

You can also Subscribe to the TestMu AI YouTube Channel and stay updated with the latest tutorials around automated browser testing, Cypress E2E testing, CI/CD, and more.

If you are a Selenium fanatic, you must have used Selenium 4. Selenium 4 is the latest version of the Selenium WebDriver with a host of new features that makes Selenium automation testing more stable and less flaky than previous versions. However, if you are intrigued to know more about what’s new in Selenium 4, you can go through the Selenium 4 tutorial to learn about the features and improvements in Selenium 4.

And that’s not all! Users can also perform mobile app testing (Android or iOS) on TestMu AI emulators & simulators and real device cloud for a multitude of configurations.

TestMu AI can be used as part of your Google Cloud CI CD pipeline to test your applications. Let us explore more about the prerequisites and the step-by-step guide to integrating TestMu AI with Google Cloud CI.

Some Prerequisites!

Make sure you are ready with the following steps mentioned before integrating Google Cloud CI with TestMu AI:

• Your TestMu AI account.
• Your code repository, on GitHub/Bitbucket etc.
• TestMu AI username and token, found in the top right ‘Access Key’ option on Automation Dashboard.

• Lastly, login into your Google Cloud CI CD platform and go to Cloud Build API.

• Click on ENABLE and add a billing account to your Google Cloud Platform for the CI/CD tool to function.

Integrate your code repository with Google Cloud CI

In order to run tests on TestMu AI via Google Cloud CI, we first need to connect our code repository. For this article, let us fork this TestMu AI Repository on GitHub to begin with.

Now let us open our GCP console and follow the below-mentioned steps:

• Click on the Console option in the top right corner.
• Create a New Project and name it ‘TestMu AI-Google-Cloud-CI-Demo’.

• Open the left pane of the dashboard and pin the ‘Cloud Build’ tool found under CI/CD category.

• Click on ‘Triggers’ from the drop-down options.

• Now we will connect our code repository using the ‘CONNECT NEW REPOSITORY’ option.

• After that, follow the remaining steps, which are pretty straightforward to complete the integration process.

Running Single Selenium Test Via Google Cloud CI

Selenium is a very popular test framework using which you can create scalable test cases for automated UI testing or cross browser testing. Building and executing Selenium projects with automation platforms is a powerful way to test websites (or web apps) at a faster pace. By using Selenium testing tools, you can test faster, more often, and more accurately.

In this section of this article on the Google Cloud CI CD pipeline, we will try to run our Selenium tests without any cluster or Docker configuration via Google Cloud CI. We just need the correct Cloud Build config file to proceed with this case. Since we have already connected to the repository, which contains some sample TestNG-Selenium tests, now we will run them via Google Cloud Build.

• Click on the ‘Create Trigger’ option and provide a name for it.

• Select the testing code repository and its branch.

• Under the ‘Configuration‘ option, select Cloud Build configuration file (yaml or json).

• In the ‘Advanced’ category, select ADD VARIABLE option. Enter your TestMu AI Access Token details as shown below.

• Click on ‘CREATE’ option, and our trigger project will be created on the selected Google Cloud CI GitHub repository.

• To run a single test from the sample TestNG Selenium GitHub repository through Google Cloud CI, click on ‘RUN‘ as shown below.

• The Google Cloud CI console shows the new build which has been triggered. The current status of this build will be ‘Running’ or ‘Successful’.

• The detailed insights of the test execution can also be found on TestMu AI Automation Dashboard.

Running Parallel Test Via Google Cloud CI

Parallel testing is a process where you run the same tests simultaneously in different environments. The goal of this process is to resolve the limitations of time and budget while still assuring quality.

To run parallel tests on TestMu AI cloud via Google Cloud CI, we need to perform minor tweaks in the cloudbuild.yml file.

Add the following command mvn test -P parallel in the args of the YAML file to allow parallel testing.

Filename: cloudbuild.yaml

steps:
- name: gcr.io/cloud-builders/docker
  args: ['run' , '-d', '--name=lt', '--network=cloudbuild', 'lambdatest/tunnel', '--user', '${_LT_USERNAME}', '--key', '${_LT_ACCESS_KEY}', '--tunnelName', 'GCloud', '--infoAPIPort', '15000','--load-balanced']
- name: curlimages/curl
  args: ['-s', '--retry-connrefused', '--connect-timeout', '5', '--max-time', '5', '--retry', '30', '--retry-delay', '2', '--retry-max-time', '60', 'http://lt:15000/api/v1.0/info']
- name: 'ubuntu'
  args: ['sleep', '20']
- name: 'bash'
  args: ['ls']
- name: 'maven'
  entrypoint: 'mvn'
  args: ['test', '-P', 'local', 'mvn test -P parallel']
  env:
  - 'LT_USERNAME=${_LT_USERNAME}'
  - 'LT_ACCESS_KEY=${_LT_ACCESS_KEY}'

Rebuild and trigger the project again from the Google Cloud Build dashboard to execute the tests in parallel.

Running Local Test Via Google Cloud CI

Local testing is a perfect time saver when you are building and testing on the go. During development, you can run and test your container image locally before deploying. You can use Cloud Code or Docker installed locally to run and test locally, including running locally with access to Google Cloud services.

However, TestMu AI allows you to run your local tests via Google Cloud CI just with the help of a configuration file!

You can test your locally hosted pages and privately hosted pages at the TestMu AI Selenium test automation platform using the TestMu AI tunnel app. Interestingly, you can also run such parallel tests via Google Cloud CI.

To run your local tests on TestMu AI cloud via Google Cloud CI, we need to perform minor tweaks in the cloudbuild.yml file.

Add the following command mvn test -P local in the args of the YAML file to allow local testing.

Filename: cloudbuild.yaml

steps:
- name: gcr.io/cloud-builders/docker
  args: ['run' , '-d', '--name=lt', '--network=cloudbuild', 'lambdatest/tunnel', '--user', '${_LT_USERNAME}', '--key', '${_LT_ACCESS_KEY}', '--tunnelName', 'GCloud', '--infoAPIPort', '15000','--load-balanced']
- name: curlimages/curl
  args: ['-s', '--retry-connrefused', '--connect-timeout', '5', '--max-time', '5', '--retry', '30', '--retry-delay', '2', '--retry-max-time', '60', 'http://lt:15000/api/v1.0/info']
- name: 'ubuntu'
  args: ['sleep', '20']
- name: 'bash'
  args: ['ls']
- name: 'maven'
  entrypoint: 'mvn'
  args: ['test', '-P', 'local', 'mvn test -P local']
  env:
  - 'LT_USERNAME=${_LT_USERNAME}'
  - 'LT_ACCESS_KEY=${_LT_ACCESS_KEY}'

The below snapshot shows the local tests being executed.
