# Run Settings
> Configure all aspects of test execution including retries, delays, timeouts, parallelism, setup/teardown, environment variables, and notifications.
Configure these settings to improve the accuracy and reliability of your tests. Each setting can be tailored to match your application's behavior and testing requirements.
### Individual Test Retries
* **Function**: Number of times a test is run again after a failure
* **Default Value**: 0
* **Purpose**: Automatically retry failed tests to handle flaky failures
### Action Delay
* **Function**: Adds a delay to each Playwright operation
* **Default Value**: 750 ms
* **Purpose**: Slow down test execution to handle timing issues or simulate real user behavior
### Test Timeout
* **Function**: Length of time before each test times out
* **Default Value**: 8 minutes
* **Purpose**: Prevent tests from hanging indefinitely and ensure timely test completion
### Parallelism Options
* **Auto (RECOMMENDED)**: Enables high parallelism with smart concurrency detection. This allows hundreds and thousands of parallel tests to run in parallel. Reach out if you need more workers.
* **Manual**: Choose a specific number of parallel tests
Ensure your tests are not interdependent before running them in parallel!
### Setup
* **Function**: Tests that run before the main test suite execution
* **Purpose**: Initialize test environment, create test data, or set up prerequisites
### Teardown
* **Function**: Tests that run after the main test suite execution
* **Purpose**: Clean up test environment, remove test data, or perform cleanup tasks
### Before Each
* **Function**: Tests that run before each individual test in the suite
* **Purpose**: Set up conditions specific to each test case
### After Each
* **Function**: Tests that run after each individual test in the suite
* **Purpose**: Clean up after each test case
### Environment
* Set the environment to use the [environment variables](/core-configuration/test-data#environment-variables) from the selected environment
### Custom Variables
* **Function**: Add custom environment variables specific to this suite
* **Purpose**: Override existing environment variables in this suite with new values
### Notification Settings
* **Options**:
* **Use project level settings**: Use the project notification settings
* **Use suite specific settings**: Override the notification settings for this suite (RECOMMENDED)
* **Disable notifications**: No notifications will be sent
* **Purpose**: Configure how test results are communicated to the team
### Notifications
* **Purpose**: Send Slack and email notifications for test results
