Environment variables

Configure environment variables

Use environment variables to avoid hard-coding secrets and to parameterize your test runs:

• Upload one or more .env files (up to 5 MB each) by dragging and dropping into the upload area:
  • You can upload .env, .yaml, .yml, .json, .properties, .ini, or .cfg files.
  • After upload, the variables become available to your test run.
• Manually add key–value pairs:
  • Click Add Variable, then enter the Key and Value.
  • Your variables are saved for this run and applied during execution.
  • Use the bin icon to delete any key-value pair

Set environment variables

The env config lets you pass an array of name-value string pairs to set environment variables on the remote machines where tests are executed.
Currently, a maximum of 20 pairs is allowed.

Environment variables can be set using any one of the following two methods:

Inline variables

Declare each variable with a name and value. BrowserStack injects these pairs into the test environment.

File-based variables

Use sources to reference one or more files containing environment variables (for example, .env files). Use variables to add or override specific pairs.
Result: the system loads values from files first, then applies overrides.

env:
  sources:
   - path/to/env/file
  variables:
   - name: "variable1"
     value: "value1"
   - name: "variable2"
     value: "value2"
