## Why is this an issue?

A `org.assertj.core.configuration.Configuration` will be effective only once you call `Configuration.apply()` or `Configuration.applyAndDisplay()`.

This rule raises an issue when configurations are set without the appropriate call to apply them.

### Noncompliant code example

    Configuration configuration = new Configuration(); // Noncompliant, this configuration will not be applied.
    configuration.setComparingPrivateFields(true);

### Compliant solution

    Configuration configuration = new Configuration();
    configuration.setComparingPrivateFields(true);
    configuration.applyAndDisplay();
    // Alternatively: configuration.apply();
