Random Values

Random variables enable you to generate and use random data in your testing workflow. Trayce uses the faker.js library to generate random data. You can use these variables like any other variables in Trayce. The syntax to use random variables is {{$randomData}}, and you can use them in the request body, authentication, parameters, and other fields.

Using Random Variables in Scripts

To use random variables in pre-request or post-response scripts, use the bru.interpolate() function. For example:

// Generate a random first name
const firstName = bru.interpolate('{{$randomFirstName}}');
console.log('Random first name:', firstName);

// Generate a random email
const email = bru.interpolate('{{$randomEmail}}');
console.log('Random email:', email);

// Generate multiple random values in one call
const userInfo = bru.interpolate(`
  Name: {{$randomFullName}}
  Job: {{$randomJobTitle}}
  Email: {{$randomEmail}}
`);
console.log(userInfo);

// Use with environment variables
const greeting = bru.interpolate('Hello {{user}} from {{$randomCity}}');

The bru.interpolate() function allows you to embed random variables in strings and have them evaluated at runtime within scripts, just like they would be in request bodies or headers.

Usage Examples

Here are some common use cases for random variables:

1. Test Data Generation:

   {
     "user": {
       "id": "{{$randomUUID}}",
       "name": "{{$randomFullName}}",
       "email": "{{$randomEmail}}",
       "phone": "{{$randomPhoneNumber}}",
       "address": {
         "street": "{{$randomStreetAddress}}",
         "city": "{{$randomCity}}",
         "country": "{{$randomCountry}}"
       }
     }
   }

2. Authentication:

   {
     "credentials": {
       "username": "{{$randomUserName}}",
       "password": "{{$randomPassword}}",
       "lastLogin": "{{$isoTimestamp}}"
     }
   }

3. Business Data:

   {
     "company": {
       "name": "{{$randomCompanyName}}",
       "catchPhrase": "{{$randomCatchPhrase}}",
       "department": "{{$randomDepartment}}",
       "account": {
         "number": "{{$randomBankAccount}}",
         "type": "{{$randomTransactionType}}"
       }
     }
   }
