Don't show Vaadin messages during TestBench test run (@PreserveOnRefresh, reload)

Question

How can I get rid of the dismiss messages displayed during a Vaadin TestBench test run in the right lower corner? Clicking by human does not help. Messages will appear on next test run.

Answer 1

You should run tests in Production Mode by setting vaadin.productionMode to true. This will disable the developer mode widget. If you're using Maven, you might have a separate profile for this purpose, such as

<profile>
    <!-- Production mode is activated using -Pproduction -->
    <id>production</id>
    <properties>
        <vaadin.productionMode>true</vaadin.productionMode>
    </properties>
    <!-- ... -->

With Gradle, put

vaadin {
   productionMode = true
}

in your build.gradle file.
