# 19. Chai ile Schema Oluşturma Örnekleri

## 1. Örnek

```javascript
// Data
const validData = {
    name: "Furkan", // required field => string
    age: 24 // optional => null or number
}

const invalidData = {
    name: 24, // required field => string
    age: "Furkan" // optional => null or number
}

// Schema
const dataSchema = {

        age: {
            type: ["number", "null"],
        }
    }
}

```

Cypress testlerini yazalım.

```javascript
// Cypress test
it("test schema with valid data", () => {
    expect(validData).to.be.jsonSchema(dataSchema);
})
 
// Cypress test
it("test schema with invalid data", () => {
    expect(badData).to.not.be.jsonSchema(dataSchema);
})
```
