# Changing Runtime Setting

**Runtime is used to define iterations, parameter usage, environment settings and other options which include re-running a failed test and collecting browser logs.** 

Head over to Monitors and select Runtime

We can keep the test as a single iteration, or set it to a specific number by selecting **Multiple iterations** option and selecting the desired number of iterations. We can also match the number of iteration to the number of parameters available, by selecting **Use all parameters**

{% hint style="info" %}
**Your test script must have a parameters file attached to it in order to use them**
{% endhint %}

To add parameters go to your test script and select parameters then simply upload your file.

We can also choose a specific environment, if we don't have one yet, we can simply create one by clicking on **Manage Environments**  which will take us to the environments page
