Built-in Test Context in Vitest

Built-in Test Context
task, expect, skip, signal, annotate, and per-test hooks from the first test argument
typescript
test('context', ({ task, expect, skip, signal, onTestFinished }) => {
console.log(task.name) // 'context'
skip(!process.env.API_KEY, 'needs API_KEY')
onTestFinished(() => cleanup())
})📌 The first test argument is the context; destructure what you need
💡 Use the context expect in concurrent tests for correct snapshots
⚡ Pass signal to fetch so a timed-out test stops its request
🔍 v5 also puts a bench fixture on the context for benchmarks
