Runnable Parameters

Behat API Context supports inline PHP expressions in request payloads using angle brackets <>.

✨ Example

Given the request contains params:
"""
{
  "timestamp": "<(new DateTimeImmutable())->getTimestamp()>",
  "uuid": "<Ramsey\\Uuid\\Uuid::uuid4()>"
}
"""

✅ Rules

  • Expressions must be wrapped in <>
  • Do not use return statements
  • Do not end expressions with a semicolon
  • Expressions must not return null

💡 Common Use Cases

Use Case Example
Timestamps <(new DateTimeImmutable())->getTimestamp()>
UUIDs <Ramsey\\Uuid\\Uuid::uuid4()>
Relative Time <(new DateTimeImmutable('+1 day'))->format('Y-m-d')>
Random value <bin2hex(random_bytes(8))>

🔥 Pro Tip

You can mix static and dynamic parameters:

{
  "start_date": "2024-01-01",
  "end_date": "<(new DateTimeImmutable('+7 days'))->format('Y-m-d')>"
}
