Two changes to main:

1. LTS-5502: Semgrep image pinned by digest. .github/workflows/Semgrep.yml on main, the copy the daily cron runs, now uses returntocorp/semgrep:1.166.0@sha256:c180f0c93a17b420c0af5006214a29d3c747c5459c732b740191adf657dd0068. This is the same pin as Nightwatch-sample-repo (#2). Checked against Docker Hub: 1.166.0 resolves to that index. The actions in the file were already SHA-pinned.

2. The Nightwatch sample on main. main held only the README and .github/; the sample lived on Nightwatch-sample-repo (#1, by @amitsi-bs). It is now on main, in the same shape as the Playwright and WebdriverIO samples:

• browserstack-load.yml, nightwatch.conf.js, package.json, tests/ and the README from Nightwatch-sample-repo. The README now names browserstack-load.yml correctly, and the branch's stray .DS_Store is left out.
• .gitignore and the SC-12282 supply-chain .npmrc (ignore-scripts, save-exact, min-release-age, ...) used by the sibling samples. ignore-scripts is safe: the sample has no install scripts and the tests run on BrowserStack.
• package-lock.json refreshed within the existing package.json ranges, so the sample lands with no high npm audit finding:
  • nightwatch 3.12.3 → 3.16.0, mocha 10.3.0 → 10.8.2
  • patches to brace-expansion, js-yaml, diff and serialize-javascript
  • two moderates remain (nightwatch → uuid); npm's only fix for those is a nightwatch 2.x downgrade.

Checked locally:

• npm ci passes on Node 22 with the new .npmrc
• nightwatch.conf.js loads and finds both tests
• gitleaks is clean
• the tests only hit the public bstackdemo.com demo site

This supersedes #1.

Walkthrough

The repository adds npm package and Nightwatch configuration, BrowserStack load-test settings and instructions, and two demo-store browser tests. It also updates ignore rules and pins the Semgrep container image by digest.

Changes: Nightwatch BrowserStack sample

Layer / File(s)	Summary
Repository and package setup package.json, .npmrc, .gitignore, .github/workflows/Semgrep.yml	Adds package metadata, dependencies, version overrides, and npm settings. Adds ignore entries and pins the Semgrep image by SHA-256 digest.
Nightwatch and BrowserStack configuration nightwatch.conf.js, browserstack-load.yml, README.md	Configures Nightwatch and a BrowserStack load test. Documents repository setup, CLI downloads, test execution, and viewing results.
Demo-store browser tests tests/bstack_test_add_to_cart.js, tests/bstack_test_checkout_flow.js	Adds a cart test that checks the product name and a checkout test that proceeds to Orders without assertions.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Before / after behavior

• observed — Modified behavior in browserstack-load.yml: Added BrowserStack load-test configuration specifying the project and test names, Nightwatch test type, user count, duration, region allocation, dependency and test-config files, error-response capture setting, and headless setting.
• observed — Modified behavior in nightwatch.conf.js: Adds the Nightwatch configuration export, including the test folder, enabled workers, Chrome browser settings, disabled screenshots, and default and Chrome WebDriver settings.
• observed — Modified behavior in tests/bstack_test_add_to_cart.js: Adds an exported browser test that visits the demo store, captures the third product’s name, adds that product to the cart, captures the cart item’s name, and asserts the names are equal.
• observed — Modified behavior in tests/bstack_test_checkout_flow.js: Adds an exported browser test that signs in with the first listed credentials, adds two items, enters first/last name, address, province, and pincode, then continues checkout and opens Orders. No assertions are added.

Then hops through checkout, step by step.
The browser visits the demo store,
While load-test settings guide the run.
A pinned image guards the workflow,
And tidy files stay out of sight.}

Review comments at @.npmrc:
- Line 20: Update the setup instructions associated with the min-release-age
policy to require a Node.js version compatible with npm 11.10.0 or later, so
dependency resolution honors the seven-day delay.

Review comments at @package.json:
- Line 7: Update the package.json test script so npm test invokes the
project-local Nightwatch runner and runs the configured suite in tests instead
of always exiting with status 1.

Review comments at @README.md:
- Around line 15-21: Update the README download and run instructions to clarify
that BrowserStack CLI downloads are ZIP archives: tell users to extract the
archive into the project root before running the CLI, and provide the
appropriate run command for each supported operating system.

36-37: Functional Correctness

The repository and inspected documentation do not establish that the load runner preserves the worker setting or starts two sessions per VU. The claimed load distortion and the proposed change are therefore unsupported.

---

29-29: Data Integrity & Integration

The inspected evidence does not establish that the load runner uses these settings without changes or that it fails to create BrowserStack sessions. The plugin omission alone does not establish the claimed failure.

Assert the contents of the new order.

Capture both selected product names and assert that the new order contains them. The clicks do not check order contents, so a missing or incorrect product can go undetected.
