helm-chart-tester

Overview

helm-unittest (Helm plugin) unit-tests the rendered chart output - assert specific fields, conditional behaviors, value substitutions - to catch template bugs before deploying.

When to use

• Team ships Helm charts (in-house apps, OSS contributions).
• A chart has conditional logic ({{ if .Values.foo }}); tests verify both branches.
• A chart's rendered output must satisfy specific shape contracts (env vars, ports, labels).
