Simulate network conditions

Test your website’s performance on different networks (2G, 3G, LTE etc.,) with varied upload & download speeds & latencies on BrowserStack Automate

In many cases, you would want to test how your websites looks and performs on browsers with different networks (2G, 3G, LTE etc.,) that have varied upload & download speeds & latencies.

To simulate these network conditions on mobile browsers, you can use one of our presets, or define your own custom network conditions using the browserstack.networkProfile and browserstack.customNetwork capabilities. You can also change the network conditions mid-way during the test run, just like in real world where the end-user’s network varies.

Specifying the network profile to start the tests with

networkProfile: 4g-lte-advanced-lossy

customNetwork: 1000

Changing the network profile while the tests are running

You can use the following REST API to switch network profiles in the middle of the test run.
