From 47093b537c4aa1643e83f396f8f8d356a76f9be2 Mon Sep 17 00:00:00 2001 From: Rohit27 <137439791+GitNinja36@users.noreply.github.com> Date: Tue, 5 Aug 2025 18:25:18 +0530 Subject: [PATCH 1/3] feat: Add comprehensive unit tests for UI functionality - Add unit tests for pkg/ui.go with 100% coverage - Add unit tests for pkg/internal/enterprise.go GetUIEndpoint with 94.4% coverage - Refactor code to use dependency injection for better testability - Test multiple scenarios like : NodePort, LoadBalancer, error handling - Made all tests self-contained and independent These changes boost test reliability and improve overall code quality. --- pkg/internal/enterprise.go | 7 +- pkg/internal/enterprise_test.go | 129 ++++++++++++++++++++++++++++++++ pkg/ui.go | 4 +- pkg/ui_test.go | 49 ++++++++++++ 4 files changed, 186 insertions(+), 3 deletions(-) create mode 100644 pkg/internal/enterprise_test.go create mode 100644 pkg/ui_test.go diff --git a/pkg/internal/enterprise.go b/pkg/internal/enterprise.go index ac7ec15..692dfdc 100644 --- a/pkg/internal/enterprise.go +++ b/pkg/internal/enterprise.go @@ -24,6 +24,9 @@ kubeslice: type: %s ` +var runCommandCustomIO = util.RunCommandCustomIO +var getNodeIPFunc = getNodeIP + func InstallKubeSliceUI(ApplicationConfiguration *ConfigurationSpecs) { util.Printf("\nInstalling KubeSlice Manager...") if ApplicationConfiguration.Configuration.HelmChartConfiguration.UIChart.ChartName == "" { @@ -112,7 +115,7 @@ func GetUIEndpoint(cc *Cluster, profile string) string { ep := "" var outB, errB bytes.Buffer -

Adds a dedicated test suite in pkg/internal/secret_test.go to cover the GetSecretName function. - Ensures robust, cross-platform test coverage using a fake kubectl binary and environment variable overrides. - Covers successful secret retrieval, command pipeline validation, and edge cases such as missing or malformed output. - No changes to production code; all improvements are limited to the test suite.
