The following is a summary of changes in this pull request made by me, your security buddy :robot:. Note that this summary is auto-generated and not meant to be a definitive list of security issues but rather a helpful summary from a security perspective.

Summary:

The changes in this pull request cover updates to the Go module dependencies, improvements to the testing of the rakkess plugin, and extensive testing of the Trivy plugin in the KubViz application.

The go.mod file update adds a new dependency, github.com/google/gnostic v0.5.7-v3refs, which is likely used for parsing and working with OpenAPI specifications. As a security best practice, the security team should review the new dependency to ensure it does not introduce any known vulnerabilities or security issues.

The changes to the rakkess plugin focus on improving the testing coverage and robustness of the plugin. The new test cases cover various aspects of the plugin's functionality, including permission checks, resource access, and error handling. The use of mocking and patching techniques allows for more targeted and controlled testing, which can help identify potential security vulnerabilities.

The changes to the Trivy plugin test suite demonstrate a strong focus on ensuring the reliability and security of the vulnerability scanning functionality in the KubViz application. The extensive use of mocking and patching, as well as the creation of a fake Kubernetes client, allows for thorough testing of edge cases and error handling, which is crucial for a security-critical component like the Trivy plugin.

Files Changed:

1. go.mod: This file was updated to add a new dependency, github.com/google/gnostic v0.5.7-v3refs, which is likely used for parsing and working with OpenAPI specifications. The security team should review this new dependency to ensure it does not introduce any known vulnerabilities or security issues.

2. agent/kubviz/plugins/rakkess/rakkes_test.go: This file contains changes related to the testing of the rakkess plugin. The new test cases cover various aspects of the plugin's functionality, including permission checks, resource access, and error handling. The use of mocking and patching techniques allows for more targeted and controlled testing, which can help identify potential security vulnerabilities.

3. agent/kubviz/plugins/trivy/trivy_test.go: This file contains changes related to the testing of the Trivy plugin, which is responsible for performing vulnerability scans on Kubernetes clusters and container images. The extensive use of mocking and patching, as well as the creation of a fake Kubernetes client, demonstrates a strong focus on ensuring the reliability and security of the vulnerability scanning functionality in the KubViz application.
