Examples Using Environment Variables

Configure tests for different environments with environment-specific variables.

Example 1: API Testing with Environment-Specific Configurations

name: APITestWithEnvironments
variables:
- name: apiBaseUrl
  value: https://staging.api.example.com
- name: timeout
  value: 30
environments:
- name: production
  variables:
  - name: apiBaseUrl
    value: https://api.example.com
  - name: timeout
    value: 60
- name: development
  variables:
  - name: apiBaseUrl
    value: https://dev.api.example.com
  - name: timeout
    value: 15
rounds:
- name: APIRound
  numberOfClients: 2
  arrivalDelay: 5000
  iterations:
  - name: FetchUserData
    httpRequest:
      url: ${apiBaseUrl}/users
      httpMethod: GET
      httpHeaders:
        X-Timeout: $timeout
    mode: R
    requestCount: 5

Run Commands:

lps run APITestWithEnvironments.yaml --environment production
lps run APITestWithEnvironments.yaml --environment development

Example 2: Secure API Calls with Token-Based Authentication

name: SecureAPIExample
variables:
- name: apiToken
  value: $read(path=../secrets/prod-token.txt)
- name: username
  value: admin
environments:
- name: staging
  variables:
  - name: apiToken
    value: $read(path=../secrets/staging-token.txt)
  - name: username
    value: staging-user
- name: development
  variables:
  - name: apiToken
    value: $read(path=../secrets/dev-token.txt)
  - name: username
    value: dev-user
rounds:
- name: SecureRound
  numberOfClients: 1
  iterations:
  - name: FetchSecureData
    httpRequest:
      url: https://secure.api.example.com/data
      httpMethod: GET
      httpHeaders:
        Authorization: Bearer $apiToken
        Username: $username
    mode: R
    requestCount: 3

Run Commands:

lps run SecureAPIExample.yaml --environment staging
lps run SecureAPIExample.yaml --environment development

Example 3: Testing Across Multiple Environments with Dynamic Endpoints

name: MultiEnvDynamicTest
variables:
- name: baseUrl
  value: https://staging.service.example.com/api
environments:
- name: production
  variables:
  - name: baseUrl
    value: https://service.example.com/api
- name: development
  variables:
  - name: baseUrl
    value: https://dev.service.example.com/api
rounds:
- name: DynamicEnvRound
  numberOfClients: 3
  arrivalDelay: 5000
  iterations:
  - name: FetchResource
    httpRequest:
      url: ${baseUrl}/resources/$counter(start=1, end=50)
      httpMethod: GET
    mode: R
    requestCount: 10

Run Commands:

lps run MultiEnvDynamicTest.yaml --environment production
lps run MultiEnvDynamicTest.yaml --environment development
