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 :

Profile Name Description
no-network Disables network settings to send device offline
airplane-mode Turns on Airplane mode setting on the device

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"
Note:
  1. no-network profile is only supported on iPhones with iOS 11 & above.
  2. airplane-mode profile is not supported on iOS. However, you can use no-network profile to simulate airplane mode on iOS.

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 :

Profile Name Bandwidth in/out (Kbps) Latency (ms) Packet Loss (%)
2g-gprs-good 50/30 500 1
2g-gprs-lossy 30/20 650 2
edge-good 250/150 300 0
2gedge-lossy 150/100 500 1
3g-umts-good 400/100 100 0
3g-umts-lossy 200/50 200 1
3.5g-hspa-good 1800/400 100 0
3.5g-hspa-lossy 900/200 190 1
3.5g-hspa-plus-good 7000/1500 100 0
3.5g-hspa-plus-lossy 2000/600 130 1
4g-lte-good 18000/9000 100 0
4g-lte-high-latency 18000/9000 3000 0
4g-lte-lossy 7000/3000 120 1
4g-lte-advanced-good 25000/18000 80 0
4g-lte-advanced-lossy 15000/10000 70 1
reset Set network settings to Browserstack’s default configuration    

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"
Note: Network profile and custom network features for app testing are only available with a BrowserStack Paid plan. View details.
