Importing Utilities

import {
  $,
  KubernetesClientHelper,
  envsubst,
  mergeYamlFiles,
  mergeYamlFilesToFile,
} from "rhdh-e2e-test-utils/utils";

Quick Examples

Bash Commands

import { $ } from "rhdh-e2e-test-utils/utils";

// Execute commands
await $`oc get pods -n my-namespace`;

// Capture output
const result = await $`oc get pods -o json`;
console.log(result.stdout);

Kubernetes Operations

import { KubernetesClientHelper } from "rhdh-e2e-test-utils/utils";

const k8s = new KubernetesClientHelper();

// Create namespace
await k8s.createNamespaceIfNotExists("my-namespace");

// Apply ConfigMap
await k8s.applyConfigMapFromObject("my-config", { key: "value" }, "my-namespace");

// Get route URL
const url = await k8s.getRouteLocation("my-namespace", "my-route");

Environment Substitution

import { envsubst } from "rhdh-e2e-test-utils/utils";

const template = "API URL: ${API_URL:-http://localhost}";
const result = envsubst(template);
// Result: "API URL: http://localhost" (if API_URL not set)

YAML Merging

import { mergeYamlFiles } from "rhdh-e2e-test-utils/utils";

const merged = mergeYamlFiles([
  "base-config.yaml",
  "override-config.yaml",
]);
