# Simulate Network Conditions

TestingBot allows you to test your mobile apps under various network conditions, including download speed, upload speed, packet loss and latency.

## Simulate network conditions using a predefined network profile

TestingBot provides a set of predefined network profiles which you can choose from.

 Profile Name | Bandwidth down/up (kbps) | Packet Loss (%) | Latency (ms) || Edge | 250/150 | 0 | 300 |
| 3G | 400/100 | 0 | 100 |
| 4G | 18000/9000 | 0 | 100 |
| airplane | 0 | 100 | 0 |

[CLI](https://testingbot.com#) [cURL](https://testingbot.com#)

```bash
testingbot espresso app.apk app-test.apk \
  --device "Pixel 6" \
  --platform-version "12" \
  --throttle-network "3G"
```

```bash
curl -u api_key:api_secret \
-X POST "https://api.testingbot.com/v1/app-automate/espresso/:id/run" \
-d '{ "espressoOptions": { "throttle_network": "3G" }, "capabilities":[{"version":"12", "deviceName":"Pixel 6", "platformName":"Android"}]}' \
-H "Content-Type: application/json"
```

## Simulate network conditions using a custom network profile

You can specify a custom set of parameters, including:

- Download rate (kbps) 
- Upload rate (kbps) 
- Packet loss (%) 
- Latency (ms)

The CLI supports predefined network profiles. For custom network profiles, use the cURL API directly.

```bash
# Predefined profiles: 4G, 3G, Edge, airplane
testingbot espresso app.apk app-test.apk \
  --device "Pixel 6" \
  --platform-version "12" \
  --throttle-network "Edge"
```

```bash
curl -u api_key:api_secret \
-X POST "https://api.testingbot.com/v1/app-automate/espresso/:id/run" \
-d '{ "espressoOptions": { "throttle_network": { "uploadSpeed": 10240, "downloadSpeed": 10240, "latency": 0, "loss": 0 } }, "capabilities":[{"version":"12", "deviceName":"Pixel 6", "platformName":"Android"}]}' \
-H "Content-Type: application/json"
```
