Node.js ships a full test runner. For many backends and libraries it replaces Jest or Mocha entirely, with zero dependencies. Writing tests // test/cart.test.js import { describe, it, beforeEach } from 'node:test'; import assert from 'node:assert/strict'; impo...
A matrix runs the same job with different combinations of values: several Node.js versions, operating systems or database versions, in parallel. A basic matrix jobs: test: runs-on: ${{ matrix.os }} strategy: matrix: os: [ubuntu-latest, windows-latest, macos-la...
FastAPI apps are easy to test because endpoints are plain functions behind an ASGI app, and dependencies can be swapped per test. A first test # test_books.py from fastapi.testclient import TestClient from main import app client = TestClient(app) def test_crea...
Go's testing tools are built in: no framework to choose. Tests live next to the code in _test.go files. Table-driven tests // slug_test.go func TestSlugify(t *testing.T) { tests := []struct { name, in, want string }{ {"simple", "Hello World", "hello-world"}, {...
pytest is the standard testing tool for Python. Tests are plain functions using plain assert , and pytest's output shows exactly what differed. First tests # test_pricing.py import pytest from pricing import apply_discount def test_ten_percent_discount(): asse...
Agents are non-deterministic, so traditional "input X gives exactly output Y" tests only go so far. A solid testing strategy combines normal tests for your code with task-level evaluations of the agent's behaviour. 1. Unit-test the tools Tools are ordinary fun...
React Testing Library encourages tests that interact with your UI the way users do: find a button by its label, click it, check what appears. Vitest runs those tests quickly and shares config with Vite. Setup npm install -D vitest jsdom @testing-library/react...
Modules are code that many teams depend on, so they deserve tests. Terraform includes a test framework: .tftest.hcl files with runs and assertions. A plan-only test # tests/naming.tftest.hcl variables { environment = "staging" domain = "shop.example.com" } run...
