Simulate network conditions

BrowserStack App Automate enables you to test mobile apps under various network conditions such as offline mode, airplane mode, and network profiles such as 3g-umts-good, 4g-lte-good, etc on BrowserStack’s real mobile device cloud.

To simulate network conditions, you can use any of our pre-defined network profiles or create a custom one. In this guide, you will learn how to:

1. Simulate device offline and airplane mode
2. Simulate network conditions using pre-defined network profiles
3. Simulate network conditions using a custom network profile

Simulate device offline and airplane mode

To simulate device offline or airplane mode, use the following network profiles :

Use the following REST API endpoint with appropriate networkProfile parameter value :

POST /app-automate/espresso/v2/build

Example:

curl -u "YOUR_USERNAME:YOUR_ACCESS_KEY" \
-X POST "https://api-cloud.browserstack.com/app-automate/espresso/v2/build" \
-d '{"networkProfile": "no-network", "devices": ["Samsung Galaxy S8-7.0"], "app": "bs://f7c874f21852ba57957a3fdc33f47514288c4ba4", "testSuite": "bs://e994db8333e32a5863938666c3c3491e778352ff"}' \
-H "Content-Type: application/json"

Simulate network conditions using pre-defined network profiles

To simulate various network conditions such as 3G, 4G, etc, use any of the following pre-defined network profiles :

Use the following REST API endpoint with appropriate networkProfile parameter value :

POST /app-automate/espresso/v2/build

Example:

curl -u "YOUR_USERNAME:YOUR_ACCESS_KEY" \
-X POST "https://api-cloud.browserstack.com/app-automate/espresso/v2/build" \
-d '{"networkProfile": "3g-umts-good", "devices": ["Samsung Galaxy S8-7.0"], "app": "bs://f7c874f21852ba57957a3fdc33f47514288c4ba4", "testSuite": "bs://e994db8333e32a5863938666c3c3491e778352ff"}' \
-H "Content-Type: application/json"

Simulate network conditions using a custom network profile

To simulate a custom network condition, create a custom network profile using the following parameters :

• Download speed (kbps)
• Upload speed (kbps)
• Latency (ms)
• Packet loss (%)

Use the following REST API endpoint with appropriate customNetwork parameter value :

POST /app-automate/espresso/v2/build

Example :

curl -u "YOUR_USERNAME:YOUR_ACCESS_KEY" \
-X POST "https://api-cloud.browserstack.com/app-automate/espresso/v2/build" \
-d '{"customNetwork": "1000, 1000, 100, 1", "devices": ["Samsung Galaxy S8-7.0"], "app": "bs://f7c874f21852ba57957a3fdc33f47514288c4ba4", "testSuite": "bs://e994db8333e32a5863938666c3c3491e778352ff"}' \
-H "Content-Type: application/json"
