angular-testingWrite Angular component tests using TestBed, ComponentHarness, and HttpTestingController with proper signal input handling.
Angular Testing is an agent skill from HoangNguyen0403/agent-skills-standard. Write Angular component tests using TestBed, ComponentHarness, and HttpTestingController with proper signal input handling. Use when writing component tests, mocking HTTP calls, or testing signal inputs.
Its SKILL.md is about 920 tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including reference files (for example `evals/evals.json` and `references/harness-pattern.md`).
It sits in Testing & QA, covering Unit testing. It works with Angular. The repository describes itself as: A collection of Agent Skills Standard and Best Practice for Programming Languages, Frameworks that help our AI Agent follow best practies on frameworks and programming laguages. The licence is MIT.
Read from SKILL.md and the folder at commit 266fd75. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Angular Testing loads about 922 tokens when it runs, and up to ~1.3k if it reads all its reference files. Until then it costs about 55 tokens; SKILL.md has 354 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

.claude/skills/angular-testing/SKILL.md (or your agent's skills folder). This skill also uses 2 other files; get the full folder from GitHub.[WEB-TEST-01] Tripartite Naming & AAA Cadence: Test names must follow Method_Scenario_ExpectedBehavior and adhere strictly to Arrange-Act-Assert.[WEB-TEST-02] Accessible Harnesses & User Actions: Query UI components via ComponentHarness (e.g. MatButtonHarness) or accessible queries; strictly ban raw CSS class selectors or arbitrary DOM traversal.[WEB-TEST-03] Ban on Component Private State & Property Inspection: Never inspect component private state or internal properties directly. Assert on visible DOM state, output events, or harness query outcomes.[WEB-TEST-04] HTTP Boundary Mocking: Intercept HTTP requests at the boundary using provideHttpClientTesting() + HttpTestingController rather than mocking internal services or methods. Tests must verify true component data flow.[WEB-TEST-05] Bug-First Regression Lock: Every PR resolving a bug ticket or with title fix(...) must introduce a test reproducing the defect prior to the fix.[WEB-TEST-02]): Use ComponentHarness (e.g. MatButtonHarness) not CSS selectors. loader.getHarness(MatButtonHarness) + await button.click(). Never query by CSS class. See harness pattern.[WEB-TEST-04]): Intercept with provideHttpClientTesting() + HttpTestingController rather than manual mocks. Call expectOne, .flush(mockData), and verify() in afterEach.[WEB-TEST-03]): Use fixture.componentRef.setInput('name', value) + fixture.detectChanges(), not direct assignment. Signals sync — no fakeAsync needed for most signal-driven tests.@angular/build:unit-test (faster, native ESM, no Karma). Configure in angular.json. Jasmine/Karma still supported. Standalone: import directly in TestBed.configureTestingModule({ imports: [StandaloneComponent] }).[WEB-TEST-01] Vague test names: Banish non-descriptive names or mixed AAA phases; follow Method_Scenario_ExpectedBehavior.[WEB-TEST-02] Raw CSS selectors / DOM traversal: Query via ComponentHarness or accessible roles, not CSS class strings.[WEB-TEST-03] Testing private state: Never inspect internal properties or use direct @Input() assignment; use setInput().[WEB-TEST-04] Manual HttpClient mocks: Always mock the network boundary with provideHttpClientTesting() + HttpTestingController.[WEB-TEST-05] Bug fix without reproduction test: Ban bug fix PRs lacking defect regression tests.When this skill applies, preserve the following domain terminology or equivalent concrete examples in the answer when relevant:
Never query by CSS class
native ESM

Write Angular component tests using TestBed, ComponentHarness, and HttpTestingController with proper signal input handling. Angular Testing is an agent skill from HoangNguyen0403/agent-skills-standard. Write Angular component tests using TestBed, ComponentHarness, and HttpTestingController with proper signal input handling.
Angular Testing fits situations like: writing component tests; mocking HTTP calls; testing signal inputs.
Run `npx skills add HoangNguyen0403/agent-skills-standard --skill angular-testing -a claude-code`. Or copy the skill folder (skills/angular/angular-testing in HoangNguyen0403/agent-skills-standard) into .claude/skills/angular-testing in your project. Claude Code loads it when a task matches its description.
Run `npx skills add HoangNguyen0403/agent-skills-standard --skill angular-testing -a codex`. Or copy the skill folder (skills/angular/angular-testing in HoangNguyen0403/agent-skills-standard) into .agents/skills/angular-testing in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add HoangNguyen0403/agent-skills-standard --skill angular-testing -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/angular-testing, .gemini/skills/angular-testing, .github/skills/angular-testing and .opencode/skills/angular-testing in your project.
SKILL.md names no scripts, command-line tools or credentials: Angular Testing is instructions for the agent only.
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Angular Testing is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 922 tokens (SKILL.md is roughly 3.7k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 363 tokens, read only when the agent opens those files.
