How to split long strings in IntelliJ IDEA automatically?

Question

I am writing a test with very long strings, and I need to split those strings:

private static final String TOO_LONG_JSON = \"{field1:field1, field2:field2 ... fi

You can use auto-formatting (CTRL + ALT + L), after few changes in Code Style settings.

• Press CTRL + ALT + S to open Settings window
• Find Code Style / Java section
• Make sure to uncheck "Line Breaks" option and check "Ensure right margin is not exceeded" option
• Press OK to accept changes you've made

Now when using auto-formatting (CTRL + ALT + L) long strings exceeding line character limit will be automatically cut into multiple lines.
