skaffold-go-integration-coverage

Example showing how to use Skaffold and ko to collect coverage profiles from integration tests, often called end-to-end tests, for Kubernetes workloads written in Go.

For a detailed explanation of how this example works, see the tutorial Go integration test coverage profiles on the Skaffold website.

Requirements

• Go v1.20 or later
• Skaffold v2 or later

Usage

1. If you are using a remote Kubernetes cluster, configure Skaffold to use your image registry:

   shellCopy

   export SKAFFOLD_DEFAULT_REPO=[your image registry, e.g., gcr.io/$PROJECT_ID]
   

   You can skip this step if you are using a local Kubernetes cluster such as kind or minikube.

2. Build the container image with support for coverage profile collection, deploy the Kubernetes resource, run the integration tests, and collect the coverage profile data:

   shellCopy

   skaffold run --profile=coverage
   

   The coverage profile data files will be in the directory reports.

Cleaning up

When you are done, remove the resources from your cluster:

skaffold delete
