Mock Umbraco configuration in test project

Question

When running unit tests on code using some Umbraco Core extensions, such as string.ToUrlSegement(), the following error is thrown:

System.Configuration.ConfigurationErrorsException: Could not load the Umbraco.Core.Configuration.UmbracoSettings.IUmbracoSettingsSection from config file, ensure the web.config and umbracoSettings.config files are formatted correctly

How do you prevent this happening?

Answer 1

Beside copying all Umbraco settings into your test projects app.config, you can add the following configuration:

<configSections>
    <sectionGroup name="umbracoConfiguration">
        <section name="settings" type="Umbraco.Core.Configuration.UmbracoSettings.UmbracoSettingsSection, Umbraco.Core" requirePermission="false" />
    </sectionGroup>
</configSections>

This prevents that exception being thrown when using Umbraco core functions dependent on configuration of a main project.
